Hereinafter, embodiments of the present invention will be described with reference to the drawings. Here, the same portions are denoted by the same reference numerals throughout the drawings.
FIG. 1 schematically shows a configuration of an air conditioning system 10 according to an embodiment of the present invention. As shown, the air conditioning system 10 includes an air conditioner 12 having at least one air blowing port 14 (14a, 14b), at least one non-contact temperature sensor 16 (16a, 16b), and at least one The target plate 18 (18a, 18b, 18c) and the control unit 20 are included. The air conditioning system 10 adjusts the temperature of a space S (see FIGS. 2 to 5) in which a plurality of facilities including a facility that generates heat is installed. The air conditioner 12 performs a heat exchange using a refrigerant to blow out cold air or hot air whose temperature is adjusted, and is called a so-called air conditioner. The air blowing port 14 of the air conditioner 12 is such that the air blowing direction and the amount of air blown are controlled independently by the air blowing ports 14a and 14b.

  The non-contact temperature sensor 16 remotely measures the temperature of the target plate 18 installed at a position away from the non-contact temperature sensor 16 in a non-contact manner, and is a movable focus that can adjust the distance to the temperature detection target. The type is used. In the air conditioning system 10 according to the embodiment of the present invention, the non-contact temperature sensor 16 is not limited to this, but an infrared radiation sensor with a focus laser function is used. Moreover, in the example of FIG. 1, one non-contact temperature sensor 16a is installed so that the temperature of two target plates 18a and 18b may be detected among two non-contact temperature sensors 16a and 16b, and the other non-contact temperature sensor 16a and 16b. The temperature sensor 16b is installed so as to detect the temperature of the remaining target plate 18c. For this reason, at least the non-contact temperature sensor 16a moves the focal direction between the two directions in which the target plates 18a and 18b are installed so that each of the two target plates 18a and 18b can be focused. A swing mechanism is added. The non-contact temperature sensor 16a that detects the temperatures of the two target plates 18a and 18b detects the temperature by selecting one of the target plates 18 according to, for example, the operation status of the equipment, or both targets. The temperature of the plate 18 is detected in order. Each of the non-contact temperature sensors 16 is connected to the control unit 20 so as to be able to perform data communication so as to transmit the detected temperature to the control unit 20.

  The target plate 18 is installed at a specific position representing the temperature in the space S, which is set in the space S to be air-conditioned by the air conditioning system 10. This specific position is not a position that is not affected by the heat generation of the equipment at all or a position that is not excessively affected by the heat generation of the equipment, but a temperature in the space S where the temperature changes moderately due to the heat generation of the equipment. Is set to an appropriate position representative of In the example of FIG. 1, three such specific positions are set in the space S, and target plates 18a to 18c are installed at the specific positions. The target plate 18 is formed of a material having high thermal conductivity and easily detecting the temperature by the non-contact temperature sensor 16 so as to accurately reflect the ambient temperature around the installation position. When the non-contact temperature sensor 16 is an infrared radiation sensor, the target plate 18 is formed of, for example, a black plastic plate (0.5 mm thickness or more). Other black materials may be used, but an emissivity suitable for the material needs to be selected by the infrared radiation sensor.

  When the non-contact temperature sensor 16 is an infrared radiation sensor, the temperature of the target plate 18 is appropriately detected according to the performance (distance counting) of the infrared radiation sensor and the distance from the sensor to the target plate 18. It is formed in a plate shape having a main surface with a possible area. Each target plate 18 is installed at each specific position with the main surface directed toward the non-contact temperature sensor 16 installed so as to detect the temperature of the target plate 18. For example, when the target plate 18 is installed in the vicinity of a particularly high temperature part of the facility that generates heat, the target plate 18 has a high temperature on the part on the high temperature part side (back surface, side part, etc.) of the facility. Coating or a cover made of a material having high heat reflectivity that suppresses the influence of heat radiation from the part is applied.

  The control unit 20 controls the operation of the air conditioner 12 based on the temperature of the target plate 18 detected by the non-contact temperature sensor 16 and is connected to the air conditioner 12 and installed. Moreover, it is good also as receiving the information regarding the presence or absence of the driving | operation of each installation 30 (refer FIGS. 2-5) from the control part of each installation 30 as needed. In the example of FIG. 1, the control unit 20 determines the air blowing direction and the air volume of one air outlet 14 a of the air conditioner 12 based on the temperatures of the two target plates 18 a and 18 b detected by the one non-contact temperature sensor 16 a. To control. For example, when the non-contact temperature sensor 16a detects the temperatures of the two target plates 18a and 18b in order, the control unit 20 calculates an average value of the two detected temperatures. And the air volume which blows off from the ventilation opening 14a while directing the ventilation opening 14a of the air conditioner 12 to the area | region in which the two target plates 18a and 18b were installed so that the calculated average temperature may approach the preset target temperature. Adjust. Further, the control unit 20 controls the blowing direction and the air volume of the other blowing port 14b of the air conditioner 12 based on the temperature of the remaining one target plate 18c detected by the other non-contact temperature sensor 16b. For example, the air outlet 14b of the air conditioner 12 is directed to the area where the target plate 18c is installed, and the amount of air blown from the air outlet 14b is adjusted so that the temperature of the target plate 18c approaches a preset target temperature. . The control unit 20 is installed near the air conditioner 12 as a control panel including a power circuit, a control circuit, and the like, for example.

Then, with reference to FIGS. 2-5, the 1st-4th Example of the air conditioning system 10 which concerns on embodiment of this invention is demonstrated. Each embodiment will be described with a focus on differences from the other embodiments. In each of the four embodiments, four production facilities 30 (30a to 30d) are installed, and the space S in which the worker P works is targeted for air conditioning. 30c has a portion 32 that is particularly hot. An infrared radiation sensor is used as the non-contact temperature sensor 16 (16a, 16b). At least in the second to fourth embodiments, a focus-movable infrared radiation sensor to which a swing mechanism is added is used.
First, in the first embodiment shown in FIG. 2, the air conditioning system 10 includes an air conditioner 12 having one air outlet 14, one non-contact temperature sensor 16, and one target plate 18. And the control unit 20.

  The direction of the non-contact temperature sensor 16 is set to an appropriate specific position representative of the temperature in the space S where the temperature of the target plate 18 is moderately affected by the heat generated by the part 32 that is particularly high in the equipment 30c. It is installed with the main surface facing. At this time, when a coating or a cover made of a material having high heat reflectivity is applied to a portion of the target plate 18 on the high temperature portion 32 side of the facility 30c, the target plate is considered in consideration of the effect of reducing the heat radiation. 18 installation positions are determined. The target plate 18 is mounted on a pole standing on the floor so as not to be affected by the temperature of the floor of the space S. At this time, for example, a pole formed of a material having low thermal conductivity may be used so that the temperature of the floor surface is not transmitted to the target plate 18 through the pole, or between the target plate 18 and the pole. A heat insulating material may be added. In the second to fourth embodiments described later, the target plate 18 (18a to 18c) is mounted on the pole as described above.

The non-contact temperature sensor 16 is installed with a focus on the target plate 18 in the direction in which the target plate 18 is installed so as to detect the temperature of the target plate 18. In FIG. 2, the non-contact temperature sensor 16 is installed in the vicinity of the air conditioner 12 and the control unit 20, but the temperature of the target plate 18 is appropriately detected and the detected temperature is sent to the control unit 20. The installation position of the non-contact temperature sensor 16 is arbitrary as long as it can be transmitted.
The controller 20 controls the air conditioner 12 so that the temperature of the target plate 18 detected by the non-contact temperature sensor 16 becomes a target temperature in the preset space S. For example, the control unit 20 adjusts the amount of air blown from the air blowing port 14 while swinging the air blowing direction of the air blowing port 14 of the air conditioner 12 in the left-right direction.

  Next, the second embodiment shown in FIG. 3 will be described. In the second embodiment, among the four facilities 30a to 30d installed in the space S, only the facilities 30a and 30b are operated, only the facilities 30c and 30d are operated, and the facilities 30a to 30d. It is assumed that three patterns of operating conditions occur, with all operating. In consideration of these operating conditions, the air conditioning system 10 in the second embodiment includes three target plates 18a to 18c installed as the target plate 18 at the following positions. That is, the target plate 18a is a first specific position representative of the temperature in the space S where the temperature changes moderately under the influence of heat generated by the facilities 30c and 30d (including the heat generated by the high-temperature portion 32). Is installed. The target plate 18b is a second specific position representative of the temperature in the space S where the temperature changes moderately under the influence of heat generated by the facilities 30a to 30d (including the heat generated by the high temperature portion 32). Is installed. Furthermore, the target plate 18c is installed at a third specific position representing the temperature in the space S where the temperature changes moderately under the influence of heat generated by the facilities 30a and 30b. Further, each target plate 18 is installed with its main surface facing the non-contact sensor 16.

  On the other hand, in order to detect the temperatures of the three target plates 18a to 18c, the non-contact sensor 16 is a plan view centered on the installation position of the non-contact sensor 16 including the direction in which all the target plates 18 are installed. It is installed so as to be able to swing so as to move the focus in the fan-shaped area. Furthermore, the non-contact sensor 16 selects the target plate 18 for detecting the temperature from among the three target plates 18a to 18c according to the operation status of the facilities 30a to 30d, and detects the temperature of the selected target plate 18. To do. That is, the non-contact sensor 16 is a target plate that is installed at a specific position where the temperature changes moderately under the influence of heat generated by the facilities 30a and 30b when only the facilities 30a and 30b are operating. 18c is selected to detect the temperature. Further, when only the facilities 30c and 30d are operating, the temperature is detected by selecting the target plate 18a, and when all the facilities 30a to 30d are operating, the temperature is selected by selecting the target plate 18b. To detect. Note that the operation of the non-contact sensor 16 as described above may be controlled by the control unit 20.

  On the other hand, the control unit 20 controls the operation of the air conditioner 12 based on the operating status of the facilities 30 a to 30 d and based on the temperature of the target plate 18 selected by the non-contact sensor 16. That is, the control unit 20 according to the present embodiment receives information related to whether or not each facility 30 is operating from the control unit (not shown) of each facility 30. Then, based on the received information, for example, when it is determined that only the facilities 30a and 30b are operating, the control unit 20 does not operate the other facilities 30c and 30d, and further, the facilities 30c and 30d. It is determined that there is no worker P in the vicinity. Then, the air conditioner 12 is set so that the temperature of the target plate 18c detected by the non-contact sensor 16 in a situation where only the facilities 30a and 30b are operating becomes the target temperature in the preset space S. To control the operation. In particular, the air volume of the air conditioner 12 is adjusted while the air outlet 14 of the air conditioner 12 is directed toward the peripheral area of the target plate 18c where the facilities 30a and 30b are installed.

Similarly, when the control unit 20 determines that only the facilities 30c and 30d are operating, the peripheral region of the target plate 18a where the facilities 30c and 30d are installed so that the temperature of the target plate 18a becomes the target temperature. In contrast, control is performed so that the air outlet 14 of the air conditioner 12 is directed. In addition, when it is determined that all of the facilities 30a to 30d are in operation, the target plate 18b and all the areas where the facilities 30a to 30d are installed so that the temperature of the target plate 18b becomes the target temperature. The air volume of the air conditioner 12 is adjusted while directing the air outlet 14 of the air conditioner 12.
In addition, the control part 20 always detects the temperature of each target plate 18a-18c by the non-contact sensor 16, without receiving the information regarding the presence or absence of the driving | operation of each equipment 30, and adjusts the space S to appropriate temperature. Moreover, it is good also as adjusting suitably the air volume of the air conditioner 12 with respect to the peripheral region of each target plate 18a-18c.

  Then, with reference to FIG. 4, the air conditioning system 10 in a 3rd Example is provided with three ventilation opening 14a-14c in which the air conditioner 12 can adjust a ventilation direction and an air volume independently. . The three target plates 18a to 18c are installed at three specific positions that represent the temperature in the space S, respectively. And the non-contact temperature sensor 16 detects the temperature of the three target plates 18a-18c in order at a predetermined timing. The control unit 20 controls the blowing direction and the air volume of each blowing port 14 of the air conditioner 12 based on the temperatures of the three target plates 18a to 18c. That is, the control unit 20 mainly directs the air blowing direction of the air blowing port 14a of the air conditioner 12 toward the peripheral region of the target plate 18a so that the temperature of the target plate 18a becomes a predetermined target temperature in the space S. At the same time, the air volume from the air outlet 14a is controlled. At the same time, the control unit 20 mainly changes the blowing direction of the blowing ports 14b and 14c so that each temperature of the target plates 18b and 18c becomes a predetermined target temperature in the space S. While directing to the peripheral area, the air volume from the air outlets 14b and 14c is controlled. In addition, by setting different target temperatures for the peripheral regions of the three target plates 18a to 18c, the control unit 20 performs air conditioning so that each of the target plates 18a to 18c has the set target temperature. Each air outlet 14 of the machine 12 may be controlled. Further, if necessary, two or more air outlets 14 may blow toward the peripheral area of one target plate 18.

  Next, in the fourth embodiment shown in FIG. 5, the air conditioning system 10 includes two non-contact temperature sensors 16a and 16b. Each of the two non-contact temperature sensors 16 a and 16 b is installed so as to detect the temperature of a different target plate 18. That is, the non-contact temperature sensor 16a is installed so as to detect the temperatures of the target plates 18a and 18b, and the non-contact temperature sensor 16b is installed so as to detect the temperature of the target plate 18c. Moreover, the control part 20 controls the ventilation direction and air volume of the two ventilation openings 14a and 14b of the air conditioner 12 based on the temperature of the target plates 18a and 18b detected by the non-contact temperature sensor 16a. At this time, the control unit 20 calculates an average value of the temperatures of the target plates 18a and 18b. Then, the air blowing directions of both the air blowing ports 14a and 14b are directed to the peripheral regions of both the target plates 18a and 18b so that the calculated average temperature becomes a predetermined target temperature in the space S, and the air blowing ports 14a and 14b. Controls the airflow from Furthermore, the control unit 20 changes the air blowing direction of the air outlet 14c to the peripheral region of the target plate 18c so that the temperature of the target plate 18c detected by the non-contact temperature sensor 16b becomes a predetermined target temperature in the space S. The air volume from the air outlet 14c is controlled.

  Now, according to the embodiment of the present invention configured as described above, the following operational effects can be obtained. That is, in the air conditioning system 10 according to the embodiment of the present invention, for example, as illustrated in FIG. 2, a facility 30 that generates heat, such as a facility that performs metal processing or a facility that heats an object to be processed, is installed. The temperature of the space S in which a specific temperature region is partially generated is adjusted. Here, the singular temperature region indicates a region where the temperature is locally different, which is clearly higher than that of other surrounding regions. This occurs when the temperature in the vicinity of 30 rises. In the example of FIG. 2, the area around the high-temperature part 32 of the facility 30c particularly corresponds to the singular temperature area. The air conditioning system 10 includes an air conditioner 12, at least one target plate 18, at least one non-contact temperature sensor 16, and a control unit 20, as can be seen in FIGS.

  The air conditioner 12 includes at least one air blowing port 14 capable of adjusting the blowing direction, and blows out cold air or hot air whose temperature is adjusted from the air blowing port 14. The target plate 18 is installed at a specific position representing the temperature in the space S, which changes under the influence of heat generated by the equipment 30. That is, the position at which the temperature changes moderately under the influence of the heat generation of the equipment 30 by appropriately considering factors that affect the temperature of the space S such as the environment around the equipment 30 that generates heat and the size of the space. And a specific position representative of the temperature in the space S. And the target plate 18 is installed in the specific position. For this reason, for example, a position where the equipment 30 that generates heat, a position that is excessively affected by the heat generated by the equipment 30, or a position that is not affected by the heat generated by the equipment 30 at all are specified positions where the target plate 18 is installed. Excluded from.

  Moreover, the non-contact temperature sensor 16 detects the temperature of the target plate 18 installed in the position away from the non-contact temperature sensor 16 in a non-contact manner. The number of installed units is determined according to the number and the number of installed target plates 18. The control unit 20 controls the operation of the air conditioner 12 based on the temperature of the target plate 18 detected by the non-contact temperature sensor 16. For example, the blowing direction and the air volume of the air conditioner 12 are controlled so that the temperature of the target plate 18 installed at a specific position representative of the temperature in the space S becomes the target temperature in the space S set in advance. .

  That is, the air conditioning system 10 according to the embodiment of the present invention detects the temperature of the target plate 18 installed at the specific position as described above by the non-contact temperature sensor 16, thereby affecting the heat generated by the equipment 30. Can be acquired as a temperature representative of the space S. As a result, the temperature of the space S can be adjusted based on an appropriate temperature that represents the inside of the space S without being directly affected by the heat generated by the equipment 30 as a disturbance, thereby preventing excessive temperature adjustment. Therefore, the temperature of the space S can be adjusted efficiently.

  In addition, as shown in FIG. 3, the air conditioning system 10 according to the embodiment of the present invention targets a space S in which a plurality of facilities 30 including a facility 30 that generates heat is installed as an air-conditioning target, and the temperature in the space S A plurality of specific positions representing the above are set, and each of the plurality of target plates 18 is installed at each specific position. For this reason, the non-contact temperature sensor 16 may detect a temperature by selecting a specific target plate 18 from among the plurality of target plates 18 according to, for example, the operating status of the plurality of facilities 30 or the like. The temperatures of the plurality of target plates 18 may be detected in order. When selecting a specific target plate 18, for example, a specific temperature that represents an appropriate temperature in the space S is reflected from the target plate 18 by reflecting the influence of heat generated by the currently operating equipment 30. The target plate 18 installed at the position is selected.

  In the example of FIG. 3, four facilities 30 a to 30 d are installed in the space S, and three target plates 18 a to 18 c are installed as the target plate 18. And in the situation where only facilities 30a and 30b are operating, the non-contact temperature sensor 16 reflects the influence of heat generation of the operating facilities and is at a specific position that represents an appropriate temperature in the space S. The installed target plate 18c is selected. In a situation where only the facilities 30c and 30d are operating, the target plate 18a installed at a specific position representing an appropriate temperature representative of the inside of the space S is reflected by the influence of heat generated by the operating facilities. Select. Furthermore, in the situation where all of the facilities 30a to 30d are operating, the target plate is installed at a specific position representing an appropriate temperature in the space S, reflecting the influence of heat generated by the operating facilities. 18b is selected. Thereby, it becomes possible to perform temperature adjustment more efficiently according to the operation status of the plurality of facilities 30.

  On the other hand, when the temperatures of the plurality of target plates 18 are sequentially detected by the non-contact temperature sensor 16, the control unit 20 calculates an average value of these temperatures as a representative temperature in the space S, and based on the calculated temperature. Temperature adjustment may be performed. Alternatively, the control unit 20 selects the highest temperature during the cooling operation of the air conditioner 12 from among the temperatures of the plurality of target plates 18, and selects the lowest temperature during the heating operation. It may be used as a representative temperature. Thereby, temperature adjustment can be performed, considering the temperature of the several area | region in which the several target plate 18 was installed.

  In addition, as shown in FIG. 4, the air conditioning system 10 according to the embodiment of the present invention includes a plurality of air blowing ports 14 that can adjust the air blowing direction and the air volume, so that each air blowing port 14 is provided. The air blowing direction and the air volume are controlled. Thereby, for example, the following control is performed. That is, by directing each of the plurality of air outlets 14 to different areas where the plurality of target plates 18 are installed, the areas of the areas where the target plates 18 are installed based on the temperature of each of the plurality of target plates 18. Temperature adjustment is performed simultaneously for each region. Moreover, the target plate 18 in which the temperature farthest from the target temperature of the space S is detected is selected from the plurality of target plates 18, and the air conditioner 12 is directed toward the area where the selected target plate 18 is installed. The air is sent from all the air outlets 14. Alternatively, one or more air outlets 14 are fixed toward an area where a specific target plate 18 is installed, and the remaining air outlets 14 are directed to a plurality of areas while swinging. Thus, temperature adjustment can be performed flexibly corresponding to a plurality of regions where the target plate 18 is installed.

  Furthermore, in the air conditioning system 10 according to the embodiment of the present invention, as shown in FIG. 5, a plurality of non-contact temperature sensors 16 may be installed. In this case, each of the plurality of target plates 18 is The temperature is detected by any one of the plurality of non-contact temperature sensors 16. As a result, a larger number of target plates 18 can be installed while sharing a plurality of target plates 18 that are targets of temperature detection among the plurality of non-contact temperature sensors 16. Further, the control unit 20 controls the blowing direction and the air volume of the plurality of air outlets 14 of the air conditioner 12 based on the temperatures detected by the plurality of non-contact temperature sensors 16. At this time, each air outlet 14 of the air conditioner 12 is made to correspond to any one of the plurality of non-contact temperature sensors 16, and the non-contact temperature sensor 16 is based on the temperature detected by each non-contact temperature sensor 16. The air blowing direction and the air volume of the air blowing port 14 corresponding to the above may be controlled. Thereby, temperature adjustment can be performed, detecting the temperature of the several target plate 18 efficiently.

  In a large space such as a production factory, a plurality of air conditioners are usually installed. For this reason, when applying this invention to such a space, what is necessary is just to install the structure of the air conditioning system 10 which concerns on embodiment of this invention as shown, for example in FIGS. .
