Description

Drain treatment structure in single body-type air conditioner

The present invention relates to an integrated air conditioner, and more particularly, to effectively treat condensate generated in an evaporator without a separate drainage device.

In general, an air conditioner includes a compressor, a condenser, a capillary tube, and an evaporator, as shown in FIG. 1, in which a refrigerant compressed in the compressor is isostatically condensed in the condenser, adiabaticly expanded in the capillary tube, and isothermally evaporated in the evaporator. It is a device that makes up. Here, the refrigerant circulating each refrigeration cycle is circulated while maintaining the following temperature.

The inlet temperature (T1) of the compressor and the outlet temperature of the evaporator are 10 to 15 ° C, the outlet temperature (T2) of the compressor is 80 to 100 ° C, and the inlet temperature (T2 ') of the condenser is 60 to 80 ° C. The outlet temperature T3 of the condenser is 40 to 50 ° C, and the inlet temperature T4 of the evaporator is 8 to 10 ° C.

On the other hand, the air conditioner can be largely divided into a separate air conditioner and an integrated air conditioner, the separate air conditioner has a structure in which an indoor unit having an evaporator or a capillary tube and an outdoor unit having a condenser and a compressor are separated, and an integrated air conditioner has one main body. The evaporator / capillary / condenser / compressor is integrated in the structure.

In particular, the integrated window air conditioner, as shown in Figure 2, the sirocco fan (1) for introducing the indoor air into the device and discharged back to the room and the evaporator (2) to heat-exchange the indoor air introduced into the device Is provided with an indoor unit, an axial fan (3) which introduces outdoor air into the device and discharges it to the outside again, and a condenser (4) cooled by the air that is cooled by the compressor and the air that is cooled by the air flowing into the device. The provided outdoor unit is integrally formed.

In addition, the integrated window type air conditioner is provided in the outer side of the axial fan (3) to suck the condensate generated in the evaporator (2), the Schringer ring (5) to allow the condensate to be scattered by the rotational force of the axial fan more It is provided, and the condensate is scattered to the high temperature condenser (4) to cool the condenser. Therefore, as the condenser is cooled by the amount of air generated by the axial fan 3 and the condensate that is scattered, the condenser pressure, which is the condensation temperature of the condenser, may be lowered, and as the condensate is evaporated by the high temperature condenser 4, Condensate removal is easy without the need for a separate condensate treatment unit except for Schringer rings and axial fans.

However, after the flow air generated by the axial fan 3 flows in through the side of the device, and the discharge direction is determined to be perpendicular to the inflow direction, the flow velocity distribution of the flow air becomes very nonuniform, resulting in large noise. There is a problem.

In addition, since the integrated window type air conditioner has an evaporator 2 in the interior part and a condenser 4 in the outdoor part, there is a problem that the overall structure is complicated and the manufacturing process takes a long time.

When the structure of the Schringer ring 5 employed in the integrated window air conditioner is applied to the integrated mobile air conditioner, the size of the mobile air conditioner is reversed. That is, the method of treating condensate water employed in the integrated window type air conditioner is possible because the structure of the indoor part having the evaporator 2 and the outdoor part having the condenser 4 as described above is possible. It becomes too large to apply to the integrated portable air conditioner for miniaturization.

As a result, the integrated mobile air conditioner according to the prior art, although not shown, is provided with a separate condensate storage chamber (not shown) in the apparatus, and takes a method of collecting and draining condensate generated from an evaporator (not shown). In addition, a pump (not shown) and a drain hose (not shown) are used to drain the condensate from the condensate storage chamber to the outside.

However, this conventional technology has the inconvenience of having to empty the condensate storage chamber every predetermined time.

In addition, there is a problem that the noise of the pump (not shown) is high, the power consumption is high, and the number of parts to be attached increases, thereby increasing the manufacturing cost.

The present invention is to solve the problems of the prior art, the purpose of improving the structure of the integrated air conditioner, to effectively treat the condensate generated in the evaporator without a separate drainage device.

In order to achieve the above object, the present invention provides a condenser and an integrated air conditioner equipped with an evaporator, wherein the evaporator and the condenser are adjacent to each other, the evaporator is located above the condenser, is generated in the evaporator It provides a condensate treatment structure of an integrated air conditioner to allow the condensate to be evaporated by the high temperature heat generated in the condenser.

Referring to the drawings to describe the above content in more detail as follows.

Condensate treatment structure of the integrated air conditioner according to the present invention, as shown in Figures 3 and 4, in the integrated air conditioner with a condenser and the evaporator, the evaporator 10 and the condenser 20 is mutually It is made adjacent, the evaporator is positioned above the condenser, so that the condensate generated in the evaporator is evaporated by the high temperature heat generated in the condenser.

At this time, the evaporator 10 and the condenser 20 may be formed integrally with each other. In this way, the structure and fabrication is very simple, the condensate generated in the evaporator 10 flows down to the condenser 20, the condensed water is evaporated and removed by the high temperature heat generated in the condenser.

In addition, in order to reduce heat loss that may occur between the evaporator 10 and the condenser 20, a condenser having a lower temperature than the refrigerant inlet 20a formed in the condenser 20, as shown in FIG. Preferably, the refrigerant outlet 20b is located at the evaporator 10 side. The reason is that since the refrigerant inlet temperature of the condenser (40-50 ° C.) is lower than the refrigerant inlet temperature (60-80 ° C.) of the condenser, the refrigerant inlet of the condenser can be kept at a lower temperature than that of the evaporator. This is because comfort can be improved by improving cooling power and generating a lot of condensate.

In addition, in order to reduce heat loss that may occur between the condenser 20 and the evaporator 10, the refrigerant outlet 10b of the evaporator having a relatively higher temperature than the refrigerant inlet 10a formed in the evaporator 10 is It is preferably located on the condenser 20 side. The reason is that since the refrigerant outlet temperature (10-15 ° C.) of the evaporator is higher than the refrigerant inlet temperature (8-10 ° C.) of the evaporator, the refrigerant inlet of the evaporator is kept at a lower temperature of the evaporator, compared to that provided at the condenser side. It is because it can improve a cooling power and generate a lot of condensed water, and can improve comfort.

In summary, in order to more effectively reduce heat loss that may occur between the condenser 20 and the evaporator 10 and to double cooling power and comfort, the refrigerant outlet 20b of the condenser and the evaporator Preferably, the refrigerant outlets 10b are provided adjacent to each other.

In addition, the condensate treatment structure of the integrated air conditioner according to the present invention, as shown in Figure 4, is provided at the bottom of the condenser 20, evaporated in the condenser of the condensate generated in the evaporator 10 Condensate receiving 30 for receiving a small amount of condensate can not be further included can be made.

At this time, the refrigerant inlet 20a side formed in the condenser 20 is immersed in the condensate accumulated on the condensate receiver 30, thereby cooling the condenser 20 and condensed water by the high temperature heat generated by the condenser. It is preferred to allow the to evaporate.

Hereinafter, with reference to the accompanying Figure 4, the operation of the air conditioner according to the present invention in detail.

As the high temperature refrigerant compressed by the compressor 40 flows into the refrigerant inlet 20a of the condenser, the condenser 20 is naturally cooled by the condensate, and condensate is evaporated and removed by the high temperature heat of the condenser. In addition, the refrigerant flowing into the refrigerant inlet 20a of the condenser flows into the condenser refrigerant outlet 20b while the temperature is gradually lowered, and then flows into the capillary tube 50.

Then, after the temperature is lowered in the capillary tube 50, the coolant introduced into the evaporator 10 through the refrigerant inlet 10a of the evaporator is gradually increased in temperature while exchanging heat with the flow air, and thus the refrigerant outlet 10b of the evaporator. Spills into. At this time, the condensate generated in the evaporator 10 is evaporated by the high temperature condenser 20 located in the lower portion while flowing in the direction of gravity by gravity, the condensate can be removed by evaporating all by the high temperature heat of the condenser If a small amount of condensate that has not been removed is collected in the condensate receiver 30, it is completely removed by the high temperature heat of the refrigerant inlet 20a side of the condenser.

Thereafter, the refrigerant flowing out of the refrigerant outlet 20b of the condenser is introduced into the compressor 40 again to repeat the circulation.
