Heat exchange line 152 has an interface 155 and an interface 156. The interface 153 of the heat exchange line 151 is connected to the main throttling device 121. The interface 154 of the heat exchange line 151 is connected to the liquid-side shutoff valve 142, and the line connecting the interface 154 and the liquid-side shutoff valve 142 is also connected to the interface 155 of the heat exchange line 152 via the bypass throttle device 122. The interface 156 of the heat exchange pipeline 152 is connected with the enthalpy-increasing gas inlet 212 of the compressor 21 or the inlet 221 of the gas-liquid separation tank 22.

Further, the interface 154 of the heat exchange line 151 may be directly connected to the liquid side stop valve 142; or the module radiator 157 in the electronic control box is connected, and the module radiator 157 is further connected with the liquid side stop valve 142, wherein the module radiator 157 is used for radiating heat of the electronic control box.

The oil separator 23 is connected to a valve port D of the four-way valve 13 and an exhaust port 211 of the compressor 21, respectively. The oil separator 23 is used for separating lubricating oil in the high-pressure gaseous refrigerant discharged from the exhaust port 211 of the compressor 21, so as to ensure safe and efficient operation of the apparatus. The lubricating oil separated by the oil separator 23 is preferably returned to the compressor 21 again, and the working principle of the oil separator 23 and the specific pipeline involved in the oil return belong to the understanding scope of those skilled in the art, and are not described herein again.

Under the refrigeration condition, the high-pressure gaseous refrigerant discharged from the exhaust port 211 of the compressor 21 reaches the valve port D of the four-way valve 13 through the oil separator 23; then, the refrigerant is conveyed to the outdoor heat exchanger 11 from a valve port C of the four-way valve 13 to exchange heat with the outdoor environment at the outdoor heat exchanger 11, so that the high-pressure gaseous refrigerant is changed into an intermediate-temperature high-pressure liquid refrigerant; then, the refrigerant is conveyed from the outdoor unit heat exchanger 11 to the main path throttling device 121, and is throttled and depressurized by the main path throttling device 121 to become a low-temperature low-pressure liquid refrigerant; and then from the main circuit throttling device 121 to the heat exchange line 151 of the economizer 15. The refrigerant passing through the heat exchange pipeline 151 is divided into two parts, one part is conveyed to the liquid side stop valve 142 and reaches the indoor unit heat exchanger, and heat exchange is carried out between the indoor unit heat exchanger and the indoor environment to absorb heat and evaporate the refrigerant into a gaseous refrigerant; then, the refrigerant is sent to a valve port E of the four-way valve 13 through the gas-side shutoff valve 141, then sent to the gas-liquid separation tank 22 through a valve port S of the four-way valve 13, and finally sent to the compressor 21 through the gas-liquid separation tank 22 to perform a new cycle of refrigerant circulation. The other part is delivered to the auxiliary throttle device 122 through the auxiliary throttle device 122, so that the temperature of the other part of the refrigerant is further reduced under the throttle control of the auxiliary throttle device 122 and delivered to the heat exchange pipeline 152 of the economizer 15, so as to further exchange heat with the refrigerant in the heat exchange pipeline 151, and thus the sub-cooling treatment of the refrigerant in the heat exchange pipeline 151 is realized. The principle and function of the supercooling process are understood by those skilled in the art, and will not be described in detail herein.

In the heating condition, the high-pressure gaseous refrigerant discharged from the exhaust port 211 of the compressor 21 passes through the oil separator 23 and reaches the valve port D of the four-way valve 13; then, the refrigerant is conveyed to the air side stop valve 141 from a valve port E of the four-way valve 13, reaches an indoor unit heat exchanger through the air side stop valve 141, and is subjected to heat exchange with the indoor environment at the indoor unit heat exchanger to release heat and be liquefied into a liquid refrigerant; then, the refrigerant is divided into two parts after passing through the liquid side stop valve 142, and one part of the refrigerant passes through the heat exchange pipeline 151 of the economizer 15 and the main path throttling device 121 in sequence to reach the outdoor heat exchanger 11 so as to exchange heat with the outdoor environment at the outdoor heat exchanger 11; then, the air is conveyed from the outdoor heat exchanger 11 to a valve port C of a four-way valve 13; and then sent from a valve port S of the four-way valve 13 to the gas-liquid separation tank 22, and finally sent from the gas-liquid separation tank 22 to the compressor 21 for a new cycle of refrigerant circulation. Another part of the refrigerant is sequentially delivered to the enthalpy-increasing gas inlet 212 of the compressor 21 through the auxiliary throttling device 122 and the heat exchange pipeline 152, so as to provide a gaseous refrigerant with intermediate pressure for the enhanced vapor injection of the compressor 21. The principle and action of enhanced vapor injection are within the understanding of those skilled in the art, and are not described herein.

In one embodiment, the outdoor unit of the air conditioner further includes a solenoid valve 161.

The outdoor unit of the air conditioner further includes an electromagnetic valve 162. The solenoid valve 162 is connected between the enhanced enthalpy inlet 212 of the compressor 21 and the connection 156 of the heat exchange line 152 of the economizer 15 to open the solenoid valve 162 when enhanced vapor injection is required by the compressor 21 to provide an intermediate-pressure gaseous refrigerant for enhanced vapor injection of the compressor 21. The solenoid valve 162 and the solenoid valve 161 are respectively connected to the port 156 of the heat exchange pipeline 152.

Further, the outdoor unit of the air conditioner further comprises a silencer 17, wherein the silencer 17 is arranged between the enthalpy-increasing air inlet 212 of the compressor 21 and the electromagnetic valve 162 and used for reducing noise generated by the pipeline due to enhanced vapor injection, so that the overall noise of the outdoor unit of the air conditioner is reduced, and the use experience of a user is improved.

Further, the outdoor unit of the air conditioner may further include a solenoid valve 163. The electromagnetic valve 163 and the main path throttling device 121 are connected in parallel between the economizer 15 and the outdoor heat exchanger 11, and are used for selectively guiding the refrigerant output by the outdoor heat exchanger 11 to the economizer 15, and the electromagnetic valve 163 is used for assisting in increasing the refrigerant volume conveyed by the main path under the refrigeration condition.

Of course, in other embodiments of the present application, the outdoor unit of the air conditioner may not include the electromagnetic valve 163, and is not limited herein.

Further, the outdoor unit of the air conditioner further includes a check valve 18. The check valve 18 is connected between the solenoid valve 163 and the economizer 15, and particularly between the solenoid valve 163 and the port 153 of the heat exchange line 151 of the economizer 15. The check valve 18 allows the refrigerant to flow only from the solenoid valve 163 to the heat exchange line 151 of the economizer 15, but does not allow the refrigerant to flow from the heat exchange line 151 of the economizer 15 to the solenoid valve 163, and further prevents the refrigerant from flowing from the heat exchange line 151 of the economizer 15 to the solenoid valve 163.

Further, the solenoid valve 16 may further include a solenoid valve 164, and the solenoid valve 164 is connected to the compressor 21 and the gas-liquid separation tank 22, respectively. Specifically, the first port of the solenoid valve 164 is connected to a pipe line connecting the port S of the four-way valve 13 and the inlet 221 of the gas-liquid separation tank 22, and the second port of the solenoid valve 164 is connected to a pipe line between the port D of the four-way valve 13 and the oil separator 23. The solenoid valve 164 is used to regulate the pressure differential.

brackets

51, 52 and 53, by way of example only, and not by way of limitation.

Based on the pipeline principle, direct pipeline connection exists between the four-way valve 13 and the solenoid valve bank 16, and direct pipeline connection exists between the solenoid valve bank 16 and the economizer 15. In view of this, the present embodiment preferably has the bracket 52 and the bracket 53 disposed opposite to each other and at a distance from each other, and the bracket 51 is located at the same side end of the bracket 52 and the bracket 53, as shown in fig. 3. In other words, the holder 51 is located at one end of the holder 52, the holder 51 is also located at one end of the holder 53, and the end of the holder 52 where the holder 51 is located and the end of the holder 53 where the holder 51 is located are located on the same side of the holder 52 and the holder 53.

In this way, the four-way valve 13 and the solenoid valve block 16 are disposed adjacent to each other, and the solenoid valve block 16 and the economizer 15 are disposed adjacent to each other, which is advantageous for shortening the length of the integrated piping connecting the four-way valve 13 and the solenoid valve block 16 and for shortening the length of the integrated piping connecting the solenoid valve block 16 and the economizer 15.

The bracket 54 is located at the other same side end of the two brackets which are oppositely arranged at intervals, and the bracket 54 is oppositely arranged with the rest one bracket. For example, in the case where the

brackets

brackets

52 and 53, the bracket 54 is located at the other side end of the

The support 51, the support 52 and the support 53 of the tube group assembly are arranged between the compressors, so that pipelines of the functional devices on the support 51, the support 52 and the support 53 connected with the compressors extend to two sides of the tube group assembly to be connected to the corresponding compressors, the length of the pipelines is favorably shortened, interference is not easily generated between the pipelines extending towards two sides, and the pipelines are conveniently arranged.

Further, the reference plane α extends in a vertical direction. In other words, it can be understood that two of the

supports

51, 52 and 53 are coplanar, the other support being parallel to but not coplanar with the two supports; or it can be understood that the

brackets

51, 52 and 53 are parallel to each other but not coplanar.

Fig. 7 shows that the

brackets

51, 52 and 53 are parallel to each other but not coplanar, which is only necessary for discussion and not limiting.

Through the mode, at least two of the bracket 51, the bracket 52 and the bracket 53 are mutually separated, so that the welding of pipelines connected among functional devices on the bracket 51, the bracket 52 and the bracket 53 can be facilitated, and the requirements of process and module compactness can be met. In addition, the stand 51, the stand 52, and the stand 53 are designed separately from each other, so that the outdoor unit can be easily adapted to various types of outdoor units, such as an outdoor unit without an economizer, an outdoor unit without a four-way valve, and the like.

Please refer to fig. 8a-8 b. In a further alternative embodiment, the planes in which two of the

supports

51, 52 and 53 lie are arranged coplanar, i.e. the planes in which two of the

supports

51, 52 and 53 lie are parallel to each other and the perpendicular projections of the two supports onto a reference plane α, which is perpendicular to the planes in which the two supports lie, overlap each other. Further, the reference plane α extends in the vertical direction. The plane of the rest of the

FIG. 8a shows the co-planar arrangement of the

brackets

51 and 52, with the bracket 53 lying in a plane that is at an angle to the plane of the

brackets

51 and 52, and with the bracket 53 lying adjacent the end of the

brackets

51 and 52 that are remote from one another; figure 8b shows the bracket 51 and bracket 52 in a coplanar arrangement, the bracket 53 lying in a plane that is at an angle to the plane of the bracket 51 and bracket 52, and the bracket 53 lying adjacent the ends of the bracket 51 and bracket 52 that are close to each other. The foregoing is merely illustrative and not limiting.

Through the mode, the plane of the rest one of the

supports

51, 52 and 53 and the plane of the rest two supports are arranged at an angle, namely the supports are arranged at an angle, so that the pipelines can be conveniently connected through bending positions, and even if the pipelines have space angles, the overall strength and the vibration resistance of the pipelines can be improved. The space of the chassis of the air conditioner outdoor unit can be better utilized, specifically, the support of the integrated module with larger occupied space can be arranged corresponding to the long edge of the chassis, and the support of the integrated module with smaller occupied space can be arranged corresponding to the short edge of the chassis, so that the requirements of process and structure compactness are met. And the angle setting between the supports can also make things convenient for the mounted position of different integrated module to exchange for the tube group assembly can satisfy the arrangement demand of the air condensing units of different models.

Similarly, the bracket 51, the bracket 52 and the bracket 53 in the above embodiment form a bracket structure similar to "ㄈ", and also relates to the case of angular arrangement between the brackets, that is, the remaining one of the bracket 51, the bracket 52 and the bracket 53 is respectively arranged at an angle with two opposite and spaced brackets, so that the above technical effects of the present embodiment are also achieved.

It should be noted that, in the above-mentioned embodiment and other embodiments of the present application, the bracket 51 may not be provided with the four-way valve 13 or is not limited to being provided with the four-way valve 13, the bracket 52 may not be provided with the solenoid valve set 16 or is not limited to being provided with the solenoid valve set 16, and the bracket 53 may not be provided with the economizer 15 or is not limited to being provided with the economizer 15. The tube assembly includes a bracket assembly comprising a bracket 51, a bracket 52 and a bracket 53, which are arranged to form the installation area, and at least part of the integrated pipeline connected with the functional device is arranged in the installation area.

In one embodiment, two of the

legs

51, 52 and 53 are angled in a plane. Specifically, the planes on which any two of the

brackets

51, 52 and 53 are located may be arranged at an angle. Further, the space between two supports that the angle set up is towards the panel of dismantling of shell 32, so after dismantling the panel under the dismantlement, the space between two supports that the angle set up is towards the user, and the degree of sheltering from is lower, conveniently carries out operations such as dismouting, maintenance and maintenance.

For example, fig. 15 illustrates the solenoid valve assembly 16 mounted to the bracket 52 and the economizer 15 mounted to the bracket 53, wherein the plane of the bracket 52 and the plane of the bracket 53 are angled, as will be described in greater detail below. Fig. 15 also shows the case where the space between the holder 52 and the holder 53 faces the lead opening 311. Fig. 15 also shows the case where the space between the holder 52 and the holder 53 is oriented toward the above-described detachable panel, since the above-described detachable panel is provided on the side of the lead opening 311.

With continued reference to fig. 3 and 4, in one embodiment, considering the direct piping connection between the four-way valve 13 and the solenoid valve set 16, the at least two integrated modules may include the integrated module 41 and the integrated module 42, and the bracket 51 and the bracket 52 have a predetermined positional relationship, including but not limited to a coplanar arrangement, a parallel arrangement, an angled arrangement, and an opposite arrangement of the plane of the bracket 51 and the plane of the bracket 52.

Please refer to fig. 8 c. In one embodiment, the bracket 51 and the bracket 52 are disposed opposite and spaced apart. Especially, when the tube set assembly of the present embodiment is installed in an outdoor unit of an air conditioner, the detachable panel is located at the same side end of the bracket 51 and the bracket 52, that is, the space between the bracket 51 and the bracket 52 faces the detachable panel. In this way, after the detachable panel is detached, the space between the bracket 51 and the bracket 52 faces the user, and the degree of shielding the space between the bracket 51 and the bracket 52 is low, so that the user can conveniently perform operations such as detaching (for example, welding, etc.), maintenance, and overhaul on the pipeline between the bracket 51 and the bracket 52.

Fig. 8c shows that the lead opening 311 is located at the same side end of the stent 51 and stent 52. Fig. 8c also shows the above-mentioned detachable panel at the same side of the holder 51 and the holder 52, since it is located at the side of the lead opening 311.

The economizer in the embodiment can be eliminated; or the economizer and the bracket 53 thereof are arranged at intervals with the bracket 51 and the bracket 52 so as to reduce the shielding degree of the economizer and the bracket 53 thereof on the space between the bracket 51 and the bracket 52 and avoid the economizer and the bracket 53 thereof from shielding the space between the bracket 51 and the bracket 52 as much as possible.

Also, the size of the bracket 53 may be smaller than the size of the

brackets

51 and 52 to further reduce the degree of obstruction of the space between the

brackets

51 and 52 by the economizer and the bracket 53 in which it is located. Fig. 8c shows the stent 53 on the same side of the stent 51 as the stent 52, in particular the stent 53 on the side of the lead opening 311 adjacent to the stent 51 and the stent 52.

Of course, considering the direct piping connection between the solenoid valve assembly 16 and the economizer 15, the at least two integrated modules may also include only the integrated module 42 and the integrated module 43, and the bracket 52 and the bracket 53 have a predetermined positional relationship, including but not limited to a coplanar arrangement, a parallel arrangement, an angled arrangement, an opposite arrangement, etc. of the plane of the bracket 52 and the plane of the bracket 53. The case in which the holder 52 and the holder 53 are opposed and spaced apart will be described in detail later.

In one embodiment, with continued reference to fig. 3 and 4, the tube-set assembly includes a mounting base 56, and the at least two integrated modules of the tube-set assembly are mounted to the mounting base 56. Further, the fixing base plate 56 is fixed to the bottom plate 31 of the outdoor unit of the air conditioner, so that the at least two integrated modules of the tube group assembly are fixed to the bottom plate 31.

Of course, in other embodiments of the present application, the tube assembly may not include the fixing bottom plate 56, and the at least two integrated modules of the tube assembly are directly fixed to the chassis 31 of the outdoor unit of the air conditioner, which is not limited herein.

Alternatively, a vibration damping structure (not shown) may be disposed below the fixed base plate 56, that is, a vibration damping structure may be disposed on a side of the fixed base plate 56 facing the chassis 31; and/or, a vibration damping structure may be disposed below the base plate 31, that is, a vibration damping structure is disposed on a side of the base plate 31 away from the tube group assembly, so as to improve the vibration damping effect of the whole air conditioner outdoor unit through the vibration damping structure. The damping structure may be a damping rubber foot pad, a damping spring, etc., and is not limited herein.

In an embodiment, with reference to fig. 3 and fig. 4, the bottom plate 31 is provided with a pipe guiding opening 311, and the pipe guiding opening 311 is used for a pipeline of the outdoor unit of the air conditioner connected to the indoor unit of the air conditioner to pass through. Also, the outlet and inlet 111 of the outdoor heat exchanger are generally disposed adjacent to the duct opening 311 of the base plate 31. The outlet and inlet 111 of the outdoor heat exchanger are the outlet and inlet of the heat exchange tube in the outdoor heat exchanger, and the refrigerant enters the outdoor heat exchanger through the inlet of the outdoor heat exchanger and is output from the outlet of the outdoor heat exchanger. Fig. 3 shows that the outlet and inlet 111 of the outdoor unit heat exchanger and the lead pipe opening 311 are disposed at the same corner of the outdoor unit of the air conditioner.

When the tube assembly is installed in the outdoor unit of the air conditioner, the tube assembly includes at least two integrated modules closer to the lead pipe opening 311 and the outlet and inlet 111 of the outdoor unit heat exchanger than the gas-liquid separation tank 22. Therefore, the length of the pipeline of the integration module for connecting the outdoor unit heat exchanger and the indoor unit heat exchanger is favorably shortened, the pipeline design of the pipe group assembly is favorably simplified, the overall volume of the pipe group assembly is reduced, the pipeline material cost is saved, and the like.

The bracket where the electromagnetic valve group is positioned is coplanar or parallel to the bracket where the economizer is positioned

Further, the reference plane γ extends in the vertical direction.

In this way, the tube set assembly can be conveniently applied to multiple compressors 21 and other scenes, that is, to an outdoor unit of an air conditioner having multiple compressors 21. The bracket 52 and the bracket 53 of the tube set assembly are arranged between the compressors 21, and pipelines for connecting the compressors 21 to the functional devices on the bracket 52 and the bracket 53 extend towards two sides of the tube set assembly so as to be connected to the corresponding compressors 21. It is understood that the embodiment is not limited to the scenario of only two compressors, and the embodiment can be applied to the scenario of a single compressor, and can also achieve the effects of saving space and facilitating the arrangement of pipelines.

Moreover, when the bracket 52 and the bracket 53 are not coplanar, that is, as shown in fig. 10, the bracket 52 and the bracket 53 are separated from each other, so that the welding of the pipes connected between the functional devices on the bracket 52 and the bracket 53 can be facilitated, and the requirements of the process and the compactness of the module can be satisfied. In addition, the stand 52 and the stand 53 are designed separately from each other, so that the outdoor unit can be conveniently adapted to more types of outdoor units, such as an outdoor unit without an economizer, an outdoor unit without a four-way valve, and the like.

Further, the reference plane δ extends in the vertical direction. The tube set assembly includes integrated piping for connecting the solenoid valve block 16 and the economizer 15 to the two compressors 21 on either side of the support 52 and the support 53. That is, the present embodiment corresponds to the application of the tube bank assembly to the multiple compressors 21 and other scenarios, which is only for example and not limited thereto.

In one embodiment, the solenoid valve set 16 includes a solenoid valve 162, a valve port of the solenoid valve 162 is provided with a silencer 17, and the solenoid valve 162 is connected to the compressor 21 through the silencer 17. Wherein the vertical projection of the silencer 17 onto the reference plane γ at least partially falls into the first spaced area 191, and the vertical projection of the silencer 17 onto the reference plane δ at least partially falls into the second spaced area 192.

Of course, the tube assembly in this embodiment may further include a bracket 54, the bracket 54 is located at the bracket 51 and the other side end of the bracket opposite to the bracket 51, and the bracket 54 is disposed opposite to the other bracket of the bracket 52 and the bracket 53. Fig. 16 shows that the bracket 54 is located at the other side end of the bracket 51 and the bracket 53, and the bracket 54 is arranged opposite to the bracket 52. That is, the bracket 54 participates in and constitutes a bracket structure similar to a "mouth" shape on the basis that the bracket 51, the bracket 52 and the bracket 53 constitute a bracket structure similar to a "ㄈ" shape.

Or the bracket 51 is arranged opposite to the bracket 52 and the bracket 53 at the same time, that is, the bracket 51, the bracket 52 and the bracket 53 are surrounded to form a bracket structure similar to a triangle, as shown in fig. 17, the bracket 51, the bracket 52 and the bracket 53 can have good structural stability, and further the overall structural stability can be ensured in the processes of integrally dismounting, mounting and maintaining the tube group assembly.

The integrated module is arranged on the tank body

Referring to fig. 18, fig. 18 is a schematic structural diagram of an outdoor unit of an air conditioner according to a fourth embodiment of the present application.

In one embodiment, the integrated module comprises a fixing member and a functional device, wherein the functional device is arranged on the fixing member. The fixing member may be a bracket for arranging the functional device as set forth in the above embodiments. Of course, the fastening element is also understood to be a connecting medium formed by the process of mounting the functional component, rather than an additionally designed component. For example, when the functional device is mounted by a soldering process, the fixing member may be a solder point formed after soldering, or the like. The following description will be given taking as an example a bracket for arranging a functional device, in which the fixing member is described in the above embodiments.

The tank 20 of the outdoor unit of the air conditioner can be used as a carrier of an integrated module of the tube set assembly, that is, a bracket where a functional device is located is disposed on the tank 20. In this way, the integrated module disposed on the tank 20 does not occupy the space of the chassis 31 of the outdoor unit, and the utilization rate of the space of the chassis 31 can be improved, so that the outdoor unit has a more compact structure, and meets the requirements of reducing stress and the like; the reasonable selection of the arrangement positions of different functional devices can be realized, for example, the functional device with high failure rate is arranged on the chassis 31, and the functional device with low failure rate is arranged on the tank body 20, so that the space of the chassis 31 is further saved; the integrated module is arranged on the tank body 20, so that elements such as vibration reduction feet and the like arranged at the bottom of the tank body 20 can be utilized, and vibration reduction elements do not need to be additionally arranged aiming at the integrated module, so that the vibration reduction cost can be saved; in addition, the integrated module is arranged on the tank body 20, so that the transmission of the vibration stress can be weakened to a certain degree, the anti-vibration effect is improved, particularly, the integrated module with the four-way valve 13 arranged on the tank body 20 can weaken the transmission of the vibration stress from the compressor 21 to a certain degree, the reasonable optimization of pipeline vibration is realized, the functional devices are combined with the support, and the fixing part can be reasonably selected according to the vibration condition. The integrated module is arranged on the tank body 20, so that the integrated module can be conveniently disassembled and assembled along with the tank body 20 integrally, and particularly, the functional device takes the tank body 20 as a carrier in the disassembling and assembling process of the pipeline of the functional device, so that the functional device can be disassembled and assembled without an additional tool.

Referring to fig. 18, in an embodiment, the fixing member of the partially integrated module of the tube set assembly is disposed on the tank 20, and the fixing member of the partially integrated module is disposed on the bottom plate 31 of the outdoor unit of the air conditioner.

Specifically, the tube-set assembly includes an integration module 41, an integration module 42, and an integration module 43. The integrated module 41 includes a bracket 51 and the four-way valve 13 disposed on the bracket 51, the integrated module 42 includes a bracket 52 and the solenoid valve set 16 disposed on the bracket 52, and the integrated module 43 includes a bracket 53 and the economizer 15 disposed on the bracket 53.

Because the number of pipelines connected to the solenoid valve set 16 is large and the pipe diameter is small, the pipelines are often welded after the solenoid valve set 16 is fixed, which leads to that if the solenoid valve set 16 is disposed on the tank 20, the welding of the pipelines connected to the solenoid valve set 16 is likely to damage the protective layer (paint surface) on the surface of the tank 20. The pipeline connecting the four-way valve 13 and the economizer 15 is relatively simple and has a large pipe diameter, so that the four-way valve 13 and the economizer 15 can be mounted on the tank body 20 after the pipeline is welded, and the influence of a welding process on the stability of the tank body 20 can be avoided.

Therefore, the present embodiment preferably has the bracket 51 and/or the bracket 53 provided on the can 20, and the bracket 52 provided on the chassis 31. Fig. 18 shows the bracket 51 and the bracket 53 disposed on the tank 20, and the bracket 52 disposed on the chassis 31, for example only, and not for limitation. Therefore, the space occupied by the integrated module on the chassis 31 is reduced as much as possible, and the influence of the welding process of the pipeline connected with the solenoid valve set 16 on the stability of the tank 20 is avoided as much as possible.

Alternatively, the tank 20, which may be the carrier of the integrated module, may be a gas-liquid separation tank and/or an oil separator or the like. The oil separator used as the carrier of the integrated module should be a relatively large oil separator. In addition, the compressor itself works to generate severe vibration, and thus is not suitable as a carrier of the integrated module. Fig. 18 illustrates the case where the tank 20 is a knock out tank 22, which is only necessary for discussion and is not intended to be limiting.

Please continue to refer to fig. 18. In one embodiment, the bracket 51 and the bracket 53 are both provided to the tank 20. Wherein the bracket 51 and the bracket 53 may be provided in the same tank 20. Considering that a small-sized oil separator is preferably used for the outdoor unit, the tank 20 suitable for installing the integrated module in the outdoor unit may only have the gas-liquid separation tank 22, and thus the bracket 51 and the bracket 53 are provided on the same tank 20, and particularly the bracket 51 and the bracket 53 are provided on the gas-liquid separation tank 22. Of course, the bracket 51 and the bracket 53 are provided in the same tank 20, which facilitates the overall assembly, disassembly, maintenance, and the like of the four-way valve 13 and the economizer 15.

The bracket 51 and the bracket 53 may be respectively provided in different tank bodies 20, and particularly, when a large-sized oil separator is used as the outdoor unit of the air conditioner, both the gas-liquid separation tank and the oil separator may be provided with an integrated module. In this way, the four-way valve 13 and the economizer 15 can be respectively disassembled, assembled and maintained, and the like, so that the operations of disassembling, assembling, maintaining and the like of the air conditioner outdoor unit are more flexible and convenient.

Further, the bracket 51 and/or the can 20 on which the bracket 53 is located is close to the lead opening 311 on the chassis 31 relative to the bracket 52. In this way, the four-way valve 13 on the bracket 51 and the economizer 15 on the bracket 53 are disposed adjacent to the duct guiding opening 311, which is beneficial to shortening the length of the pipeline connecting the four-way valve 13 and the economizer 15 to the heat exchanger of the indoor unit, and is further beneficial to simplifying the pipeline design of the outdoor unit of the air conditioner, reducing the overall volume of the outdoor unit of the air conditioner, saving the cost of the pipeline material, and the like.

Further, the bracket 51 and/or the bracket 53 are disposed on the tank 20 adjacent to the outlet and the inlet of the outdoor heat exchanger, that is, the bracket 51 and/or the bracket 53 are disposed on the tank 20 opposite to the bracket 52 adjacent to the outlet and the inlet of the outdoor heat exchanger. Since the outlet and inlet of the outdoor heat exchanger are usually located at the same corner position as the pipe guiding opening 311 of the bottom chassis 31, fig. 18 shows that the bracket 51 and/or the bracket 53 is located at the position where the tank 20 is close to the pipe guiding opening 311 of the bottom chassis 31 relative to the bracket 52, and also shows that the bracket 51 and/or the bracket 53 is located at the position where the tank 20 is close to the outlet and inlet of the outdoor heat exchanger relative to the bracket 52.

Therefore, the length of the pipeline connecting the four-way valve 13 with the outdoor heat exchanger and the length of the pipeline connecting the economizer 15 with the outdoor heat exchanger are advantageously shortened, and further, the pipeline design of the outdoor air conditioner unit is facilitated, the overall size of the outdoor air conditioner unit is reduced, the material cost of the pipeline is saved, and the like.

Please continue to refer to fig. 18. In one embodiment, the frame 53 on which the economizer 15 is located is provided to the tank 20. Since the economizer 15 has the interface 153, the interface 154, the interface 155, and the interface 156, the interface of the economizer 15 is disposed away from the tank 20, that is, the interface 153, the interface 154, the interface 155, and the interface 156 are disposed away from the tank 20. Therefore, even if the economizer 15 is mounted on the tank 20 and then the interface is welded with the integrated pipeline, the interface of the economizer 15 is separated from the tank 20, so that the influence of the welding process of the pipeline on the stability of the tank 20 can be avoided to a certain extent.

Referring to fig. 19, fig. 19 is a schematic structural diagram of an outdoor unit of an air conditioner according to a fifth embodiment of the present application.

In one embodiment, the outdoor unit of an air conditioner has a first tank 24 and a second tank 25. The first tank 24 and the second tank 25 may be the tank 20 described above, that is, the gas-liquid separation tank and/or the oil separator described above. The first tank 24 and the second tank 25 are arranged at intervals, and the bracket arranged on the tank 20 in the above embodiment is bridged between the first tank 24 and the second tank 25.

In this way, the integrated module does not occupy the space of the chassis of the outdoor unit of the air conditioner, and the degree of combination between the integrated module and the tank 20 can be reduced, so as to avoid the influence on the stability of the tank 20 caused by the welding process of the functional devices of the integrated module as much as possible.

Referring to fig. 20, fig. 20 is a schematic structural diagram of an outdoor unit of an air conditioner according to a sixth embodiment of the present application.

In one embodiment, the bracket 51 is provided on the can 20, and the bracket 52 and the bracket 53 are provided on the chassis 31. As for the arrangement of the support 52 and the support 53 on the chassis 31, the vertical projections of the support 52 and the support 53 on the reference plane γ as explained in the above embodiments may be staggered from each other, and the plane on which the support 52 is located, the plane on which the support 53 is located, and the reference plane γ are parallel to each other, as shown in fig. 9 and 10; or the plane of the support 52 and the plane of the support 53 are arranged at an angle as explained in the previous embodiment; or the bracket 52 and the bracket 53 are disposed opposite and spaced from each other as described in the following embodiments. Fig. 20 shows the case where the

brackets

52 and 53 are opposed and spaced apart. And the foregoing several arrangements will be described in detail in the corresponding parts of the present application, and will not be described herein again.

Please continue to refer to fig. 19. In one embodiment, the stability of the tank 20 can be ensured considering that when the welding position of the pipeline connected to the solenoid valve set 16 is far away from the solenoid valve set 16, the welding process of the pipeline will not damage the tank 20. Thus, unlike the previous embodiment, this embodiment allows the bracket 52 on which the solenoid valve assembly 16 is located to be mounted on the tank 20 to minimize the space occupied by the tube set assembly on the chassis 31.

For the case that the bracket disposed on the tank 20 is bridged between the first tank 24 and the second tank 25 as explained in the above embodiments, in this embodiment, the bracket 51 and the bracket 53 are disposed on the first tank 24 and the second tank 25, and the bracket 52 is bridged between the first tank 24 and the second tank 25, as shown in fig. 19, so as to increase the distance between the solenoid valve set 16 on the bracket 52 and the first tank 24 and the second tank 25, and avoid the damage to the tank 20 caused by the welding process of the pipeline connected to the solenoid valve set 16 as much as possible, thereby ensuring the stability of the tank 20.

Dodging port

Referring to fig. 3 and 21, fig. 21 is a schematic top view of a tube group assembly of the outdoor unit of the air conditioner shown in fig. 3.

The following description will be made with respect to the case where the above-described

brackets

52 and 53 are disposed opposite to and spaced apart from each other, and the bracket 51 is located at the same side end of the

brackets

52 and 53.

In one embodiment, the side of the bracket 53 remote from the bracket 51 is provided with an escape opening 55, as shown in fig. 21. The perpendicular projection of the escape opening 55 onto the reference plane β is located in the area defined by the perpendicular projection of the outer edge of the bracket 52 onto the reference plane β. The reference plane β is perpendicular to the relative orientation of the holder 52 and the holder 53. Further, the reference plane β extends in a vertical direction.

In this way, part of the integrated pipeline may be disposed at the avoiding opening 55, that is, the avoiding opening 55 provides an avoiding position for the integrated pipeline, which is beneficial to reducing the overall volume of the pipe assembly and the space occupied by the pipe assembly, and is further beneficial to improving the space utilization rate of the outdoor unit of the air conditioner.

Specifically, the outdoor unit of the air conditioner includes an integrated pipe 611 and an integrated pipe 612, the integrated pipe 611 is connected to the outdoor unit heat exchanger (the outlet and the inlet 111 of the outdoor unit heat exchanger are shown in fig. 3 and 21, the same applies hereinafter) and the valve port C of the four-way valve 13, and the integrated pipe 612 is connected to the outdoor unit heat exchanger and the main throttle device 121, respectively. Wherein, the integrated pipe 611 and the integrated pipe 612 are disposed at the avoidance port 55.

The support where the economizer is positioned provides clearance

Please continue to refer to fig. 3. In one embodiment, the four-way valve 13 is disposed on the bracket 51, the economizer 15 is disposed on the bracket 53, and the gas-side shutoff valve 141 is located on a side of the bracket 53 facing away from the four-way valve 13. The height of the bracket 53 is lower than that of the bracket 51, and the integrated piping 621 of the valve port E of the four-way valve 13 connected to the gas-side shutoff valve 141 extends above the bracket 53.

Through the mode, the integrated pipeline 621 can be conveniently connected with the air side stop valve 141 through the space formed by the height difference between the bracket 53 and the bracket 51, and then connected with the indoor unit heat exchanger. In addition, the height of the bracket 53 is low, which means that the size of the bracket 53 is small, the space occupied by the bracket 53 can be reduced, the space utilization rate is improved, the material required for manufacturing the bracket 53 is small, and the material cost for manufacturing the bracket 53 is saved.

It should be noted that the height of the bracket 51 and the height of the bracket 53 are to be understood as the height of the tops of both the bracket 51 and the bracket 53 in the vertical direction when the tube set assembly is properly placed. Specifically, the height of the bracket 53 itself may be lower than the height of the bracket 51 itself, so that the height of the bracket 53 is lower than the height of the bracket 51; or the height of the bracket 53 and the height of the bracket 51 are not obviously different, but the bracket 53 and the bracket 51 are offset in the vertical direction, and the bracket 53 is offset relative to the bracket 51 towards the bottom of the bracket 51, so that the tops of the bracket 51 and the bracket 53 have a height degree, namely the height of the bracket 53 is lower than that of the bracket 51. Fig. 3 illustrates the bracket 53 itself having a lower height than the bracket 51 itself, which is only required for discussion and is not limiting.

Further, the four-way valve 13 includes a four-way valve main body 131. The four-way valve body 131 is provided with a port C, a port D, a port E, and a port S of the four-way valve 13. Specifically, a valve port D of the four-way valve 13 is disposed on one side of the four-way valve body 131, and a valve port C, a valve port E, and a valve port S of the four-way valve 13 are disposed on one side of the four-way valve body 131 departing from the valve port D. Wherein, the valve port E, the valve port S and the valve port C of the four-way valve 13 are sequentially arranged along the direction close to the bracket 53.

Please continue to refer to fig. 3 and 21. Integrated circuit 621 includes a first tube segment 6211, a second tube segment 6212, a third tube segment 6213, and a fourth tube segment 6214. First pipe segment 6211 is connected to valve port E and extends in a direction away from valve body 131. The second pipe segment 6212 is connected to the first pipe segment 6211 and extends toward the bracket 53 in the axial direction of the four-way valve body 131. The third pipe segment 6213 is connected to the second pipe segment 6212 and extends in a direction close to the four-way valve body 131. The fourth pipe segment 6214 is connected to the third pipe segment 6213 and extends above the bracket 53, wherein the fourth pipe segment 6214 is connected to the air side stop valve 141, i.e., for connecting the indoor unit heat exchanger, and the height difference between the bracket 53 and the bracket 51 is used for providing clearance for the fourth pipe segment 6214.

Fig. 3 and 21 show that the first 6211 and third 6213 tube sections are straight tubes, the second 6212 tube section is connected to the first 6211 and third 6213 tube sections, respectively, by bends, and the third 6213 and fourth 6214 tube sections are connected by bends as well. Therefore, the mode is favorable for improving the anti-vibration effect of the pipe group assembly by additionally arranging a plurality of pipeline bending positions to weaken the transmission of the vibration stress.

Further, with continued reference to FIGS. 3 and 4, the tube set assembly also includes integrated piping 631. The integration line 631 connects the economizer 15 and the liquid side shutoff valve 142, respectively. Specifically, the integrated pipe 631 is connected to the interface 154 of the heat exchange pipe of the economizer 15, and the integrated pipe 631 is further connected to the liquid side stop valve 142, and further connected to the indoor unit heat exchanger.

The interface 154 of the economizer 15 is arranged opposite to the liquid side stop valve 142, the integrated pipeline 631 extends to the upper side of the support 53, and the integrated pipeline 631 can be conveniently connected with the liquid side stop valve 142 through a space formed by the height difference between the support 53 and the support 51, so as to be connected with an indoor unit heat exchanger.

Fig. 3 illustrates that the integrated circuit 631 includes a first pipe segment 6311 and a second pipe segment 6312. With continued reference to fig. 3 and 4, a first pipe segment 6311 is connected to interface 154 of heat exchange line 151 of economizer 15 and a second pipe segment 6312 is connected to liquid side shut-off valve 142. In fig. 3, the first pipe segment 6311 and the second pipe segment 6312 are not directly connected, and when the economizer 15 needs to connect the module radiator in the electronic control box as described in the above embodiment, the first pipe segment 6311 may be connected to the module radiator in the electronic control box first, and then connected to the second pipe segment 6312, and then connected to the liquid side stop valve 142; while the first tube segment 6311 and the second tube segment 6312 may be directly connected when the economizer 15 does not need to be connected to the module radiator in the electronic control box.

Please continue to refer to fig. 3. In one embodiment, when the tube set assembly is installed in the outdoor unit of the air conditioner, the tube set assembly comprises at least two integrated modules, which are closer to the lead pipe opening 311 and the outlet and inlet 111 of the outdoor unit heat exchanger than the gas-liquid separation tank 22. Therefore, the length of the pipeline of the integration module for connecting the outdoor unit heat exchanger and the indoor unit heat exchanger is favorably shortened, the pipeline design of the pipe group assembly is favorably simplified, the overall volume of the pipe group assembly is reduced, the pipeline material cost is saved, and the like.

Please continue to refer to fig. 1a-1b and fig. 3. In one embodiment, to facilitate the connection of the pipes between the outdoor unit and the indoor unit and shorten the length of the pipes, the lead opening 311 of the bottom chassis 31 is usually disposed near the edge of the bottom chassis 31, i.e. near the casing 32 on the side of the bottom chassis 31.

Since the installation, welding, maintenance, etc. of the outdoor unit of the air conditioner are generally performed through the outer casing 32 on the side of the base plate 31, the outer casing 32 near the pipe opening 311 of the base plate 31 is generally designed with a detachable panel 321, and a space formed by detaching the detachable panel 321 contacts the inside of the outdoor unit of the air conditioner to perform the installation, welding, maintenance, etc. of the outdoor unit of the air conditioner.

In view of this, the height of the bracket 53 is lower than the height of the bracket 51, and the bracket 53 is closer to the lead opening 311 on the chassis 31 than the bracket 51, so that the bracket 53 is closer to the detachable panel 321 on the housing 32 than the bracket 51. In this way, since the height of the bracket 53 is low, the pipeline on the side of the bracket 53 away from the lead opening 311 can be exposed, that is, the operations such as installation, welding and maintenance of the pipeline behind the bracket 53 are facilitated, and a sufficient operation space is reserved for the operations such as installation, welding and maintenance of the pipeline behind the bracket 53. In addition, the bracket 53 is closer to the pipe guiding opening 311 on the chassis 31 than the bracket 51, so that the economizer 15 on the bracket 53 is closer to the pipe guiding opening 311, which is beneficial to shortening the length of the pipeline of the economizer 15 connected with the indoor unit heat exchanger, and is further beneficial to simplifying the pipeline design of the pipe assembly, reducing the overall volume of the pipe assembly, saving the pipeline material cost and the like.

It should be noted that, the bracket 51 and the bracket 53 described in this embodiment may be disposed opposite to and spaced apart from the bracket 52 and the bracket 53 described in the above embodiments, and the bracket 51 is located at the same side end of the bracket 52 and the bracket 53. Of course, in other embodiments of the present application, the bracket 51 and the bracket 53 may be disposed opposite and spaced apart from each other, and the like, which is not limited herein.

The bracket where the electromagnetic valve group is positioned is opposite to the bracket where the economizer is positioned at intervals

Please continue to refer to fig. 3. In one embodiment, the solenoid valve assembly 16 is mounted to the bracket 52 and the economizer 15 is mounted to the bracket 53. The bracket 52 and the bracket 53 are opposed to each other and spaced apart from each other. The tube set assembly also includes an integrated circuit disposed between the bracket 52 and the bracket 53 and connecting the solenoid valve block 16 and the economizer 15.

In this way, the opposing arrangement of the bracket 52 and the bracket 53 means that the linear distance of the piping connection between the solenoid valve block 16 and the economizer 15 is short, which facilitates shortening of the pipe length and also facilitates the piping alignment. Moreover, the mode can improve the integral integration level of the pipe group assembly, is favorable for reducing the integral volume of the pipe group assembly and the space occupied by the pipe group assembly, and further is favorable for improving the space utilization rate. In addition, because direct pipeline connection exists between the solenoid valve bank 16 and the economizer 15, and the support 52 and the support 53 are arranged oppositely, the pipeline alignment and positioning can be facilitated in the process of welding the integrated pipeline with the solenoid valve bank 16 and the economizer 15, and the welding process is convenient to operate.

In this embodiment, the height of the connection port of the economizer 15 for the integrated piping is lower than the height of the connection port of the solenoid valve block 16 for the integrated piping, so that the integrated piping has at least one bent pipe section. This means that, the design that the height of the interface of the economizer 15 for the integrated pipeline is lower than the height of the interface of the solenoid valve bank 16 for the integrated pipeline is adopted, so that the bending design of the integrated pipeline for connecting the solenoid valve bank 16 and the economizer 15 is convenient, the bending number is convenient to increase, and the increase of the bending is beneficial to weakening the transmission of the vibration stress and improving the vibration reduction effect of the integrated pipeline.

Please refer to FIG. 4. Specifically, the solenoid valve set 16 includes a solenoid valve 161, and the solenoid valve 161 is used for further connecting the gas-liquid separation tank 22 to selectively conduct the economizer 15 to the gas-liquid separation tank 22 through the integrated pipeline. The electromagnetic valve 161 is specifically connected to the interface 156 of the heat exchange pipeline of the economizer 15 and the inlet 221 of the gas-liquid separation tank 22. The solenoid valve 16 further includes a solenoid valve 162, the solenoid valve 162 being adapted to further couple to the compressor 21 to selectively communicate the economizer 15 to the compressor 21 via the integrated circuit described above. The solenoid valve 162 is specifically connected between the enthalpy-increasing air inlet 212 of the compressor 21 and the interface 156 of the heat exchange line of the economizer 15.

The integrated piping connecting the solenoid operated valve pack 16 and the economizer 15 includes the integrated piping 632. The height of the port of the economizer 15 for connecting the integrated circuit 632 is lower than the height of the ports of the solenoid valve 161 and the solenoid valve 162 for connecting the integrated circuit 632, so that the integrated circuit 632 has at least one bent pipe section, which is beneficial to reducing the transmission of vibration stress and improving the vibration damping effect.

Further, the integrated circuit 632 includes a first sub-circuit 6321 and a second sub-circuit 6322. The solenoid valve 161 and the solenoid valve 162 are connected in parallel through a first sub-line 6321. The first sub-pipe 6321 may be specifically a tee joint, and the like, two interfaces on the same side of the first sub-pipe 6321 are respectively connected with the electromagnetic valve 161 and the electromagnetic valve 162, and an interface on the other side of the first sub-pipe 6321 is connected with the second sub-pipe 6322, so that the first sub-pipe 6321 is connected with the economizer 15 through the second sub-pipe 6322. The second sub-conduit 6322 has at least one curved tube segment to facilitate damping of the transmission of vibrational stresses and improve damping.

Further, the second sub-conduit 6322 includes a first linear conduit segment 63221, a second linear conduit segment 63222, a third linear conduit segment 63223, a first curved conduit segment 63224, and a second curved conduit segment 63225. One end of the first linear tube section 63221 is connected to the first sub-tube 6321, one end of the second linear tube section 63222 is connected to the economizer 15, and the first and second

linear tube sections

63221 and 63222 extend toward each other in the opposite direction of the cradle 52 and cradle 53. The third linear tube section 63223 is obliquely disposed with respect to the relative orientation of the carriage 52 and the carriage 53, with one end of the third linear tube section 63223 being engaged with the other end of the first linear tube section 63221 through the first curved tube section 63224, and the other end of the third linear tube section 63223 being engaged with the other end of the second linear tube section 63222 through the second curved tube section 63225.

That is, the above explains the case where the second sub-pipe 6322 has two curved pipe sections, i.e., the first curved pipe section 63224 and the second curved pipe section 63225. In this way, when the height of the interface of the economizer 15 to which the integrated pipeline 632 is connected is lower than the height of the interface of the solenoid valve 161 and the solenoid valve 162 to which the integrated pipeline 632 is connected, the solenoid valve group 16 and the economizer 15 are connected through the integrated pipeline 632, and meanwhile, the second sub-pipeline 6322 is facilitated to be additionally bent, so that the transmission of the vibration stress is facilitated to be weakened, and the vibration reduction effect is improved.

Please refer to FIG. 21. In an exemplary embodiment, the perpendicular projection of the solenoid valve assembly 16 on the reference plane β and the perpendicular projection of the economizer 15 on the reference plane β are offset from each other, in particular, in a vertical direction (i.e., perpendicular to the paper of fig. 21), wherein the reference plane β is perpendicular to the relative direction of the bracket 52 and the bracket 53. In the above manner, the integrated circuit connecting the solenoid valve assembly 16 and the economizer 15 has at least one curved pipe section, i.e., the integrated circuit 632 has at least one curved pipe section.

In view of this, the height of the bracket 53 is lower than the height of the bracket 52, and the bracket 53 is closer to the lead opening 311 on the chassis 31 than the bracket 52, so that the bracket 53 is closer to the detachable panel 321 on the housing 32 than the bracket 52. In this way, since the height of the bracket 53 is low, the pipeline on the side of the bracket 53 away from the lead opening 311 can be exposed, that is, the operations such as installation, welding and maintenance of the pipeline behind the bracket 53 are facilitated, and a sufficient operation space is reserved for the operations such as installation, welding and maintenance of the pipeline behind the bracket 53. In addition, the bracket 53 is closer to the pipe guiding opening 311 on the chassis 31 than the bracket 52, so that the economizer 15 on the bracket 53 is closer to the pipe guiding opening 311, which is beneficial to shortening the length of the pipeline of the economizer 15 connected with the indoor unit heat exchanger, and is further beneficial to simplifying the pipeline design of the pipe assembly, reducing the overall volume of the pipe assembly, saving the pipeline material cost and the like.

It should be noted that the opposing and spaced arrangement of the

brackets

52 and 53 in this embodiment can be specifically applied to the opposing and spaced arrangement of the

brackets

52 and 53 described in the above embodiments, and the bracket 51 is located at the same side end of the

brackets

52 and 53.

The injection pipe and the exhaust pipe are arranged in parallel and in parallel

Referring to fig. 22, fig. 22 is a schematic structural diagram of an outdoor unit of an air conditioner according to a seventh embodiment of the present application.

In one embodiment, the compressor 21 has an exhaust port 211 and an enthalpy-increasing intake port 212. The outdoor unit of the air conditioner further includes an exhaust pipe 641 and an injection pipe 642. The discharge pipe 641 is connected to the discharge port 211 of the compressor 21. Further, the exhaust pipe 641 is also connected to an oil separator 23. An injection pipe 642 is connected to the enthalpy-increasing intake port 212 of the compressor 21. Further, the injection pipe 642 is further connected to the interface of the heat exchange pipeline of the economizer, specifically, the injection pipe 642 is connected to the muffler 17 and is connected to the solenoid valve 162 through the muffler 17, and is further connected to the interface of the heat exchange pipeline of the economizer through the solenoid valve 162.

At least part of the pipe section of the exhaust pipe 641 is arranged parallel and side by side with at least part of the pipe section of the injection pipe 642. Therefore, the exhaust pipe 641 and the injection pipe 642 can be integrally formed, that is, the exhaust pipe 641 and the injection pipe 642 can be equivalent to a pipe section, so that the pipeline rigidity and the vibration resistance of the exhaust pipe 641 and the injection pipe 642 can be obviously enhanced, and the transmission of the vibration stress can be further weakened.

Further, the at least partial pipe section of the exhaust pipe 641 and the at least partial pipe section of the parallel injection pipe 642 are connected by an interconnecting piece 643, wherein the interconnecting piece 643 provides a rigid connection, so that the exhaust pipe 641 and the injection pipe 642 are integrated, that is, the exhaust pipe 641 and the injection pipe 642 are equivalent to one pipe section, and the exhaust pipe 641 and the injection pipe 642 vibrate synchronously under the action of a vibration stress, so that the exhaust pipe 641 and the injection pipe 642 integrally exhibit strong pipeline rigidity and vibration resistance, and further the vibration stress can be reduced.

Optionally, the distance between the at least part of the tube segment of the exhaust pipe 641 and the at least part of the tube segment of the parallel injection tube 642 is greater than or equal to 10mm and less than or equal to 100 mm. In this way, the distance between the at least partial section of the exhaust pipe 641 and the at least partial section of the parallel injection pipe 642 can be adapted to the size of the interconnecting piece 643, the distance between the at least partial section of the exhaust pipe 641 and the at least partial section of the parallel injection pipe 642 is sufficient to accommodate the interconnecting piece 643, and the distance between the at least partial section of the exhaust pipe 641 and the at least partial section of the parallel injection pipe 642 facilitates the interconnecting piece 643 to connect the exhaust pipe 641 and the injection pipe 642. The interconnecting piece 643 may be a pipe clamp, etc., and is not limited herein.

Further, the sum of the lengths of the at least some pipe sections of the exhaust pipe 641 accounts for 50% or more of the total length of the exhaust pipe 641, and the sum of the lengths of the at least some pipe sections of the injection pipe 642 accounts for 50% or more of the total length of the injection pipe 642.

As such, the at least partial section of the exhaust pipe 641 and the at least partial section of the injection pipe 642 have a sufficient pipe length to facilitate a rigid interconnection between the at least partial section of the exhaust pipe 641 and the at least partial section of the injection pipe 642 via the interconnecting member 643. Specifically, the above-mentioned at least part of the tube section of the exhaust pipe 641 and the above-mentioned at least part of the tube section of the injection tube 642 have a sufficient tube length to allow a rigid interconnection therebetween through a sufficient number of the interconnects 643.

Please continue to refer to fig. 22. In one embodiment, the exhaust pipe 641 and the injection pipe 642 respectively have at least one linear segment, and the linear segment of the exhaust pipe 641 and the linear segment of the injection pipe 642 are parallel and arranged side by side. The present embodiment preferably provides the linear sections of the exhaust pipe 641 and the injection pipe 642 in parallel and side-by-side arrangement, as the interconnection between the linear sections is facilitated by an interconnection 643, such as a pipe clamp.

For example, fig. 22 shows that the linear segment 6411 of the exhaust pipe 641 and the linear segment 6421 of the injection pipe 642 are arranged in parallel and side-by-side, and the linear segment 6411 of the exhaust pipe 641 and the linear segment 6421 of the injection pipe 642 are interconnected by an interconnecting member 643, such as a pipe clamp. Of course, in other embodiments of the present application, the exhaust pipe 641 and the injection pipe 642 may have a larger number of linear pipe sections that are parallel to each other and are arranged side by side, and are not limited herein.

Please continue to refer to fig. 22. In one embodiment, the exhaust pipe 641 and the injection pipe 642 have at least one U-bend section, respectively. Since the U-shaped bent pipe section is beneficial to reducing the transmission of the vibration stress, the exhaust pipe 641 and the injection pipe 642 can reduce the transmission of the vibration stress on the exhaust pipe 641 and the injection pipe 642 by designing the U-shaped bent pipe section, which is beneficial to prolonging the service life of the pipelines including the exhaust pipe 641 and the injection pipe 642.

For example, fig. 22 shows the exhaust pipe 641 having a U-bend 6412 and a U-bend 6413, and the injection pipe 642 having a U-bend 6422 and a U-bend 6423. Of course, in other embodiments of the present application, the exhaust pipe 641 and the injection pipe 642 may have other numbers of U-shaped bent pipe sections, which are not limited herein.

Please continue to refer to fig. 3 and 22. In one embodiment, the compressor 21 is connected to the oil separator 23 through the exhaust pipe 641, and the oil separator 23 is further connected to the valve port D of the four-way valve 13. The oil separator 23 is arranged close to the four-way valve 13, so that the oil separator 23 can be integrated in a pipe set assembly, and the integration level is improved; and is advantageous in shortening the length of the pipeline connecting the oil separator 23 and the four-way valve 13, thereby facilitating simplification of the pipeline design of the pipe stack assembly, reduction of the overall volume of the pipe stack assembly, saving of the material cost of the pipeline, and the like.

Further, the outdoor unit of the air conditioner includes a bracket 51 and a bracket 52. The four-way valve 13 is provided on the bracket 51. The plane in which the bracket 51 lies is at an angle to the plane in which the bracket 52 lies. Preferably, the

brackets

52 and 53 are opposite and spaced apart, and the bracket 51 is located at the same side end of the

brackets

52 and 53, so that the plane of the bracket 51 is arranged at an angle to the plane of the bracket 52. The oil separator 23 is further provided at a corner formed by the bracket 51 and the bracket 52 on the basis of being provided adjacent to the four-way valve 13, which contributes to further improving the integration of the tube group assembly.

Further, the solenoid valve 162 connected to the injection tube 642 is disposed on the bracket 52, which is advantageous for further improving the integration of the tube set assembly.

Please continue to refer to fig. 3 and 22. In one embodiment, in the case that the tube set assembly is disposed on the bottom chassis 31 of the outdoor unit of the air conditioner, the four-way valve 13 has two opposite ends along the axial direction thereof, a side of the four-way valve 13 away from the bottom chassis 31 is provided with the valve port D, and the oil separator 23 is located on a side of the four-way valve 13 facing the bottom chassis 31. One end of the integration pipe 622 is connected to the valve port D of the four-way valve 13, the integration pipe 622 extends in the axial direction of the four-way valve 13 and extends from the outside of the end of the four-way valve 13 to the side of the four-way valve 13 facing the chassis 31, and the oil separator 23 is connected to the other end of the integration pipe 622.

Through the above manner, the integrated pipeline 622 extends from the oil separator 23 from bottom to top, and the lubricating oil and the like doped in the refrigerant conveyed by the integrated pipeline 622 naturally flow back to the oil separator 23 under the action of gravity, so that the separation effect of the oil separator 23 can be ensured. Meanwhile, the integrated pipeline 622 is additionally provided with a bent position, so that the transmission of the vibration stress from the compressor 21 is reduced, and the service life of the pipeline including the integrated pipeline 622 is prolonged.

The valve bodies are arranged side by side

Please continue to refer to fig. 3. In one embodiment, the tube-set assembly includes an integrated module 42. The integrated module 42 includes a support 52 and a valve body disposed on the support 52. The number of the valve bodies is at least two, and the at least two valve bodies are arranged side by side on the support 52. The integrated module 42 further includes at least two integrated pipelines, each integrated pipeline being connected to a corresponding valve body.

Through the mode, the at least two valve bodies are arranged on the support 52 side by side, so that the integration level of the pipe group assembly is improved, the support 52 can be used for mounting and fixing the at least two valve bodies, the number of required supports can be reduced, and the material cost is saved. And above-mentioned at least two valve bodies are concentrated and are arranged, conveniently concentrate maintenance, detection, change operation etc. to these at least two valve bodies.

It should be noted that the valve body may include the solenoid valve 16, the main throttle device 121, the auxiliary throttle device 122, the check valve 18, and the like described in the above embodiments, that is, the valve body may be at least one of the solenoid valve 16, the main throttle device 121, the auxiliary throttle device 122, the check valve 18, and the like. The valve body is exemplified as the solenoid valve set 16, which is only needed for discussion, and is not limited to the valve bodies arranged side by side.

In one embodiment, the at least two valve bodies include a solenoid valve 161 and a solenoid valve 162, and the solenoid valve 161 and the solenoid valve 162 are disposed side by side on the bracket 52. The tube set assembly also includes a frame 53 and an economizer 15 mounted on the frame 53.

Please refer to FIG. 4. As in the previous embodiment, the bracket 52 is spaced apart from and opposite to the bracket 53. The at least two integrated circuits include an integrated circuit 632, and the integrated circuit 632 includes a first sub-circuit 6321 and a second sub-circuit 6322. The first sub-pipe 6321 may be specifically a tee joint, etc., a first nozzle of the first sub-pipe 6321 is connected to the first valve port of the solenoid valve 161, a second nozzle of the first sub-pipe 6321 is connected to the first valve port of the solenoid valve 162, a third nozzle of the first sub-pipe 6321 is connected to the economizer 15, and a third nozzle of the first sub-pipe 6321 is specifically connected to the economizer 15 through the second sub-pipe 6322.

The first sub-conduit 6321 lies in a plane parallel to the direction of opposition of the support 52 and the support 53. In this way, the first sub-pipe 6321 is provided by using the space between the bracket 52 and the bracket 53, and the space between the bracket 52 and the bracket 53 can be sufficiently used, thereby improving space utilization. Meanwhile, the plane where the first sub-pipeline 6321 is located is parallel to the relative direction of the support 52 and the support 53, and is not obliquely arranged relative to the relative direction of the support 52 and the support 53, so that the extension of other pipelines can be prevented as much as possible, avoidance can be provided for other pipelines, the pipeline layout design of the pipe group assembly is facilitated, and the high integration of the pipe group assembly is further facilitated.

In one embodiment, the second port of the solenoid valve 162 is provided with a muffler 17, and the solenoid valve 162 is connected to the compressor 21 through the muffler 17. Wherein the muffler 17 is located below the solenoid valve 162. Preferably, the muffler 17 extends in a direction away from the solenoid valve 162.

In this way, when the bracket 52 and the bracket 53 are disposed opposite to each other and at an interval, the muffler 17 does not occupy a space between the bracket 52 and the bracket 53, so as to reserve a sufficient space for arranging other pipes between the bracket 52 and the bracket 53, which is beneficial to the pipe layout design of the pipe assembly, and is further beneficial to the high integration of the pipe assembly.

In one embodiment, the at least two valve bodies further include a solenoid valve 163, and the solenoid valve 163 is located at one side of the

solenoid valves

161 and 162, i.e., the

solenoid valves

161, 162 and 163 are arranged side by side. The solenoid valve 163 is connected to the economizer 15 and is also used for connecting to the outdoor heat exchanger 11, and is used for selectively guiding the refrigerant output by the outdoor heat exchanger 11 to the economizer 15.

The integrated module 42 further includes a check valve 18, the check valve 18 is disposed at a first port of the solenoid valve 163, and the check valve 18 is disposed below the solenoid valve 163. The solenoid valve 163 is connected to the economizer 15 through the check valve 18, and a second port of the solenoid valve 163 is connected to the outdoor heat exchanger 11.

In this way, when the bracket 52 and the bracket 53 are disposed opposite to each other and at an interval, the check valve 18 does not occupy a space between the bracket 52 and the bracket 53, so as to reserve a sufficient space for arranging other pipelines between the bracket 52 and the bracket 53, thereby facilitating the pipeline layout design of the tube bank assembly, and further facilitating the high integration of the tube bank assembly.

Because the electromagnetic valve 163 is directly connected to the outdoor heat exchanger through the pipeline, when the tube set assembly of the present embodiment is applied to an outdoor unit of an air conditioner, the electromagnetic valve 163 is closer to the outlet and the inlet 111 of the outdoor heat exchanger than the electromagnetic valve 161 and the electromagnetic valve 162, which is beneficial to shortening the length of the pipeline connecting the electromagnetic valve 163 to the outdoor heat exchanger, and is further beneficial to simplifying the pipeline design of the tube set assembly, reducing the overall volume of the tube set assembly, and saving the material cost of the pipeline. The solenoid valve 163 is disposed closer to the solenoid valve 161 or the solenoid valve 162, and is not limited thereto.

In one embodiment, the at least two valve bodies further comprise solenoid valves 164. The solenoid valve 164 is located at one side of the

solenoid valves

161 and 162, that is, the

solenoid valves

161, 162 and 164 are arranged side by side. The solenoid valve 164 is used to connect the compressor 21 and the gas-liquid separation tank 22.

Since the electromagnetic valve 164 is directly connected to the gas-liquid separation tank 22 through a pipeline, when the tube set assembly of the present embodiment is applied to an outdoor unit of an air conditioner, the electromagnetic valve 164 is closer to the compressor 21 and the gas-liquid separation tank 22 than the electromagnetic valve 161 and the electromagnetic valve 162, which is beneficial to shorten the length of the pipeline connecting the electromagnetic valve 164 to the compressor 21 and the gas-liquid separation tank 22, and is further beneficial to simplify the pipeline design of the tube set assembly, reduce the overall volume of the tube set assembly, and save the material cost of the pipeline. The solenoid valve 164 is disposed closer to the solenoid valve 161 or closer to the solenoid valve 162, and is not limited thereto.

For example, FIG. 3 shows solenoid valve 161, solenoid valve 162, solenoid valve 163, and solenoid valve 164 arranged side by side. The solenoid valve 163 is located on the side of the solenoid valve 162 facing away from the solenoid valve 161, and the solenoid valve 164 is located on the side of the solenoid valve 161 facing away from the solenoid valve 162.

In one embodiment, the tube set assembly further includes a four-way valve 13, an oil separator 23, and an integrated circuit 622. One end of the oil separator 23 is connected to the four-way valve 13 via an integrated line 622, and the other end of the oil separator 23 is connected to the compressor 21. The oil separator 23 is closer to the solenoid valve 164 than the four-way valve 13, and the second port of the solenoid valve 164 is connected to the integration pipe 622 so that the solenoid valve 164 is connected to the compressor 21. Moreover, the oil separator 23 is disposed adjacent to the solenoid valve 164, which is advantageous for shortening the length of the pipeline connecting the solenoid valve 164 and the integrated pipeline 622, thereby facilitating simplification of the pipeline design of the pipe set assembly, reduction of the overall volume of the pipe set assembly, and saving of the pipeline material cost.

Cover body

Referring to fig. 3, 23 and 24, fig. 23 is a schematic structural view of an outdoor unit of an air conditioner according to an eighth embodiment of the present application, and fig. 24 is a schematic structural view of the outdoor unit of the air conditioner shown in fig. 23, which is seen from above.

In one embodiment, the tubing set assembly includes a housing 70. The housing 70 encloses a receiving space 71. The pipe group assembly further comprises an integrated module, the integrated module comprises a functional device and an integrated pipeline, and the functional device is connected with the integrated pipeline. The integrated module is arranged in an accommodating space 71 formed by enclosing the cover body 70, and the cover body 70 can slow down the diffusion of the refrigerant leaked from the integrated pipeline.

In this way, when refrigerant leakage detection is performed on the integrated pipeline of the pipe set assembly, if refrigerant leakage occurs in the integrated pipeline, the cover 70 can slow down the diffusion of refrigerant leaked from the integrated pipeline, which means that the refrigerant is restricted by the cover 70 and temporarily stays in the accommodating space 71 formed by the cover 70 in an enclosing manner, and the rising of the concentration of the refrigerant in the accommodating space 71 can be accurately captured by the detection probe, wherein the detection probe is an instrument for refrigerant leakage detection, so that the detection efficiency and the detection precision of refrigerant leakage detection can be improved by designing the cover 70.

For the situation that the cover body 70 is not designed, the refrigerant leaked from the integrated pipeline to the external environment can be diffused quickly, so that the concentration of the refrigerant in the external environment around the integrated pipeline is difficult to change obviously, the detection probe is difficult to capture the refrigerant leakage situation, and the detection efficiency and the detection precision of the refrigerant leakage are low.

It should be noted that, referring to fig. 1, the cover 70 of the present embodiment is different from the casing assembly 30 of the outdoor unit of the air conditioner, which includes the chassis 31 and the casing 32, the cover 70 is independent from the casing assembly 30, and on the basis that the pipe assembly is disposed in the inner space formed by the chassis 31 and the casing 32, the integrated module of the pipe assembly is further disposed in the accommodating space 71 defined by the cover 70.

In one embodiment, the side of the cover 70 is formed with an open area 72, and the open area 72 connects the accommodating space 71 to the outside. The area of the open area 72 is smaller than the area of the side surface of the cover 70, that is, more parts of the open area 72 are in an open state, and the accommodating space 71 is communicated with the external environment, so as to allow the integrated pipeline of the integrated module to pass through the open area 72, and further be connected with a functional device outside the pipe assembly. For example, FIG. 23 shows the side of the enclosure 70 where the open area 72 is located completely free of the enclosure 70. Also, the side surfaces of the cover 70 should be understood to include the top surface, the bottom surface, and the surfaces disposed around the opposite direction of the top surface and the bottom surface of the cover 70.

The number of the open areas 72 is at most one, so as to reduce the degree of communication between the accommodating space 71 and the external environment as much as possible, and restrict the refrigerant from staying in the accommodating space 71 as much as possible, that is, slow down the refrigerant diffusion as much as possible. Of course, in other embodiments of the present application, the accommodating space 71 may not be provided with the opening area 72, and the integrated pipeline of the integrated module connected to the external functional device is disposed through the cover 70, that is, an opening is formed on the cover 70 for the integrated pipeline to pass through (which will be described in detail below), so as to reduce the degree of communication between the accommodating space 71 and the external environment to the maximum extent, that is, slow down the refrigerant diffusion to the maximum extent.

In addition, referring to fig. 1, the cover 70 may cooperate with the chassis 31 and the casing 32 of the housing assembly 30 to form an accommodating space 71. For example, the bottom of the accommodating space 71 is directly disposed on the chassis 31, i.e., the bottom of the accommodating space 71 is not provided with the cover 70; or at least one side of the accommodating space 71 abuts against the housing 32, i.e., the at least one side of the accommodating space 71 is not provided with the cover 70. In this way, the use of the cover 70 can be reduced to save material cost, and the overall weight of the tube set assembly can be reduced, thereby facilitating the overall assembly, disassembly, and transportation of the tube set assembly.

Fig. 23 shows that the bottom of the accommodating space 71 is directly disposed on the chassis 31, the bottom of the accommodating space 71 is not provided with the cover 70, and the side of the cover 70 facing the outlet and inlet 111 of the outdoor heat exchanger is provided with the open area 72, which is only necessary for discussion and not limiting.

Please continue to refer to fig. 3 and 23. In one embodiment, the number of the integrated modules is at least two, each integrated module includes a bracket, the functional device of each integrated module is disposed on the respective bracket, and the brackets of the at least two integrated modules have a predetermined positional relationship. The cover body 70 is disposed at the periphery of the support of each integrated module, that is, the cover body 70 uses the support of the integrated module as a carrier, which can facilitate the disposition of the cover body 70, and facilitate the enclosure of the cover body 70 at the periphery of the support of the integrated module.

Further, the at least two integrated modules include an integrated module 41, an integrated module 42, and an integrated module 43. The integrated module 41 includes a bracket 51 and a four-way valve 13 disposed on the bracket 51, the integrated module 42 includes a bracket 52 and a solenoid valve set 16 disposed on the bracket 52, and the integrated module 43 includes a bracket 53 and an economizer 15 disposed on the bracket 53. The

brackets

52 and 53 are arranged opposite and spaced apart, and the bracket 51 is located at the same side end of the

brackets

52 and 53.

The cover 70 is provided on the outer periphery of the holder 51, the holder 52, and the holder 53. When the casing 70 has an open area 72, the open area 72 is disposed opposite to the bracket 52, specifically, the open area 72 faces the outlet and inlet 111 of the outdoor heat exchanger, so that the pipeline of the four-way valve 13 connected to the outdoor heat exchanger and the pipeline of the economizer 15 connected to the outdoor heat exchanger can pass through. Specifically, the integrated pipe 611 connecting the outdoor heat exchanger and the valve port C of the four-way valve 13 and the integrated pipe 612 connecting the outdoor heat exchanger and the main throttle device 121 are connected to the outdoor heat exchanger through the open area 72.

When the tube set assembly is installed in the outdoor unit of the air conditioner, the open area 72 faces the outlet and inlet 111 of the outdoor unit heat exchanger, and the open area 72 allows the integrated pipeline of the four-way valve 13 connected to the outdoor unit heat exchanger and the integrated pipeline of the economizer 15 connected to the outdoor unit heat exchanger to pass through and be connected to the outdoor unit heat exchanger. The open area 72 faces the outlet and inlet 111 of the outdoor heat exchanger, which is beneficial to shortening the integrated pipeline of the four-way valve 13 connected to the outdoor heat exchanger and the integrated pipeline of the economizer 15 connected to the outdoor heat exchanger, and is further beneficial to simplifying the pipeline design of the pipe set assembly, reducing the overall volume of the pipe set assembly, saving the material cost of the pipeline, and the like.

Of course, in other embodiments of the present application, the bracket surrounded by the cover 70 may be only one or two of the bracket 51, the bracket 52 and the bracket 53, and when the bracket surrounded by the cover 70 is any two of the bracket 51, the bracket 52 and the bracket 53, the any two brackets may be disposed oppositely, disposed in parallel, disposed in a coplanar manner, disposed at an angle, and the like, which is not limited herein.

Please continue to refer to fig. 24. In one embodiment, the housing 70 is provided with a first opening 73, and at least a portion of the integrated piping of the tubing set assembly extends to the exterior of the housing 70 through the first opening 73 to connect the integrated piping inside the housing 70 with external functional devices. Specifically, the integrated piping of the four-way valve 13, the solenoid valve assembly 16, and the economizer 15 to which external functional devices are connected may extend to the outside of the housing 70 through the first opening 73.

The pipe diameter of the integrated pipeline that the big or small adaptation of first opening 73 passes through when guaranteeing that the integrated pipeline can pass, furthest reduces the degree that accommodation space 71 and external environment communicate, and then furthest slows down the refrigerant diffusion, guarantees refrigerant leak testing's detection efficiency and detection precision.

It will be appreciated that the manifold may extend outwardly through a first opening 73 in the cover 70 in addition to the open area 72 described above.

Please continue to refer to fig. 23. In one embodiment, the cover 70 is provided with a second opening 74 to allow the detection probe to be inserted into the interior of the cover 70 through the second opening 74 for refrigerant leakage detection. Of course, in other embodiments of the present application, the detection probe may extend into the interior of the casing 70 through the opening 72 for detecting the refrigerant leakage, which is not limited herein.

Further, the tube set assembly includes a cover 75 covering the second opening 74, and the cover 75 is configured to be opened by pushing the test probe and to be automatically closed after the test probe is removed from the interior of the cover 70. In this way, while the detection probe is allowed to be inserted into the cover 70 through the second opening 74, the cover 75 can be automatically closed, which is further beneficial to reducing refrigerant diffusion.

In one embodiment, the cover 70 has the basic function of protecting the integrated module disposed inside the cover 70, and has the protection functions of preventing rain and snow, besides the function of slowing down the diffusion of the refrigerant.

Further, the material of the cover 70 is a fireproof material and/or a noise reduction material. The design of the cover body 70 can concentrate and reduce noise of the integrated modules arranged in the cover body 70, noise reduction materials do not need to be respectively arranged for all the integrated modules to reduce noise, the cost of the noise reduction materials can be saved, and meanwhile, the noise reduction materials are convenient to disassemble and assemble. Moreover, the cover body 70 can concentrate on the integrated module arranged in the cover body for fire prevention, and when the refrigerant is a flammable refrigerant, the cover body 70 made of a fireproof material is favorable for inhibiting the fire from spreading, so that a good fire prevention effect can be achieved.

Alternatively, the material of the cover 70 is preferably soundproof cotton, felt, rubber leather sheath, etc., and the material of the cover 70 has a certain noise reduction function and a certain fire prevention function, which is not limited herein.

In one embodiment, the bracket includes at least two uprights 57 and at least one cross-member 58. The at least two columns 57 are arranged side by side and at intervals, the cross beam 58 is bridged between the adjacent columns 57, and the functional devices of the integrated module of the tube group assembly are arranged on the cross beam 58.

In this way, the functional device and the integrated circuit connected to the functional device can be mounted, maintained, and the like through the gap formed between the adjacent pillars 57. Particularly, the functional device and the integrated pipeline connected with the functional device are convenient to disassemble and assemble, the integrated pipeline is convenient to weld, and the like.
