[First Embodiment]
First, a configuration of an air conditioning system including an air conditioning device according to the first embodiment of the present invention will be described with reference to FIGS. 1 to 3.

(Configuration of air conditioning system)
As shown in FIG. 1, the air conditioning system 500 according to the first embodiment includes a vapor compression air conditioner 110, a showcase 80, and an air conditioner 100.

The air conditioner 100 includes an indirect vaporization heat exchanger 1. The showcase 80 also includes a refrigerator 81. The refrigerator 81 includes a condenser 21 and an evaporator 22. The vapor compression air conditioner 110 and the showcase 80 are installed in the store 90. Further, the indirect vaporization heat exchanger 1 and the condenser 20 are installed outdoors. The store 90 is an example of the "indoor" in the claims.

(Configuration of air conditioner)
The air conditioner 100 according to the first embodiment includes an indirect vaporization heat exchanger 1, as shown in FIG. The indirect vaporization heat exchanger 1 also includes a core portion 2. In the store 90, the wall surface 91 side is the X1 direction, and the side opposite to the wall surface 91 is the X2 direction. The right side of the showcase 80 when viewed from the X2 direction is the Y1 direction, and the left side is the Y2 direction. The ceiling 92 side is the Z1 direction, and the floor surface 93 side is the Z2 direction.

As shown in FIG. 2, the core part 2 includes a wet flow path 16 and a dry flow path 17. The wet flow paths 16 and the dry flow paths 17 are configured to be alternately stacked. The wet flow path 16 and the dry flow path 17 are held at a predetermined interval by a spacer. The predetermined interval is, for example, 5 mm. A partition 18 is provided between the wet flow path 16 and the dry flow path 17. The partition wall 18 is made of a material capable of conducting heat and impervious to water. For example, the partition 18 is made of a polypropylene film or a thin sheet. A nonwoven fabric 16b is provided on the inner surface 16a of the wet channel 16. For example, the non-woven fabric 16b is made of polypropylene or a hygroscopic filter paper. Water fed from the water supply pipe 30 (see FIG. 1) is retained in the non-woven fabric 16b. A fan 14a (see FIG. 1) is installed at the inlet of the wet flow path 16. A fan 11a (see FIG. 1) is installed at the entrance of the dry flow path 17. Further, the dry flow path 17 spreads over the entire width of the core portion 2 in the X direction, and the taken-in air 11 spreads over the entire width in the X direction and flows from the Z1 direction to the Z2 direction. In addition, the wet flow path 16 extends over the entire width of the core portion 2 in the X direction, and the taken-in air 14 extends over the entire width in the X direction and flows from the Z2 direction to the Z1 direction. As described above, the wet flow path 16 and the dry flow path 17 have substantially the same shape in the XZ direction and overlap each other in the Y direction. Further, the water discharged from the wet flow path 16 is drained to the outside by the drain pipe 31 (see FIG. 1).

Further, as shown in FIG. 1, the indirect vaporization heat exchanger 1 has a first inlet 10 a that takes the air 10 into the dry flow path 17. The air 10 is heated by the heat entering the store 90 from the outside or the air 50 taken into the refrigerator 81 from the store 90 by the condenser 21 and heated by the heated air 51 discharged into the store 90. Further, the indirect vaporization heat exchanger 1 has an outlet 10b that supplies the air 12 discharged from the outlet of the dry flow path 17 to the store 90. The first inlet 10a is connected to the upper portion (upper Z1 side) of the store 90 by the first duct 40. Further, the outlet 10b is connected to the lower portion of the store 90 (lower portion on the Z2 side) by the second duct 41.

The indirect vaporization heat exchanger 1 also has a second inlet 13 a that takes the outside air 13 into the wet flow path 16. Further, the indirect vaporization heat exchanger 1 has an outlet 13b for discharging the air 15 discharged from the outlet of the wet flow path 16. Further, the outlet 13b is connected to the air intake port 15a of the condenser 20 by the third duct 42.

Here, in the first embodiment, the indirect vaporization heat exchanger 1 moves the inside of the dry flow passage 17 by the heat of vaporization generated by the vaporization of the moisture in the wet flow passage 16 by the air 14 in the wet flow passage 16. The air 11 flowing and the air 14 flowing in the wet channel 16 are cooled, the air 12 cooled in the dry channel 17 is supplied from the outlet 10b to the store 90, and the air cooled in the wet channel 16 is also supplied. 15 is exhausted from the outlet 13b to the condenser 20.

Specifically, the indirect vaporization heat exchanger 1 uses the fan 11 a installed at the inlet of the dry flow path 17 to heat the warm air 10 in the store 90 from the first inlet 10 a via the first duct 40. It is configured to supply air. Further, the indirect vaporization heat exchanger 1 is configured to supply the outside air 13 from the second inlet 13a by the fan 14a installed at the inlet of the wet flow path 16. Further, when the air 14 passes through the wet flow path 16, the water retained in the nonwoven fabric 16b (see FIG. 2) is vaporized, and the heat of vaporization generated cools the air 14 and the wet flow path 16. Then, the dry flow path 17 and the air 11 are cooled by the heat of vaporization generated in the wet flow path 16 via the partition wall 18. The air 12 cooled in the dry flow path 17 passes through the second duct 41 and is supplied to the store 90. Further, the air 15 cooled in the wet flow path 16 passes through the outlet 13b and is discharged to the condenser 20 from the air intake port 15a of the condenser 20 via the third duct 42. The warm air 10 in the store 90 is an example of "warm air in the room" in the claims. The air 11 and the air 14 are examples of “air flowing in the dry flow path” and “air flowing in the wet flow path” in the claims, respectively.

Here, an operation example of the air conditioning system according to the first embodiment will be described. As shown in FIG. 3, it is assumed that the outside air 13 has a temperature/humidity th1 and the warm air 10 in the store 90 has a temperature/humidity th2. Here, th1 is, for example, a temperature of 40° C. and a humidity of 34% RH. Also, th2 is, for example, a temperature of 35° C. and a humidity of 44.5% RH. Further, for example, when the surface area of the wet flow passage 16 is adjusted so that the humidity of the air 14 flowing through the wet flow passage 16 rises to 85% RH, the air 14 in the wet flow passage 16 is At the exit of enthalpy, the enthalpy increases by H1, but the temperature drops to 29°C. Further, the enthalpy of the air 11 in the dry flow passage 17 is reduced by H2 due to the heat exchange with the wet flow passage 16, so that the temperature at the outlet of the dry flow passage 17 drops to 32°C. As a result, in the store 90, the air 10 at 35° C. is cooled to 32° C. by the air conditioner 100 and circulated. Further, outside air of 40° C. is cooled to 29° C. by the air conditioner 100 and is supplied to the condenser 20.

Thus, in the air conditioner 100, the indirect vaporization heat exchanger 1 takes in the warm air 10 in the store 90 from the first inlet 10a, cools it via the dry flow path 17, and supplies the air to the store 90. The outside air 13 taken in through the second inlet 13a is cooled to a temperature lower than the outside air temperature by the wet flow path 16 and exhausted to the condenser 20 installed outdoors.

The air conditioner 100 is configured to supply the air 90 cooled in the wet flow path 16 to the inside of the store 90 and exhaust the air 15 to the condenser 20 from the outlet 13b. As a result, the air 11 flowing in the dry flow passage 17 can be cooled by the indirect vaporization heat exchanger 1, and the air 14 flowing in the wet flow passage 16 can also be cooled. As a result, by supplying the air 12 cooled by the dry flow path 17 to the store 90, the temperature rise in the store 90 can be suppressed.

The indirect vaporization heat exchanger 1 is provided with the second duct 41 that allows the interior 10b and the store 90 to communicate with each other. As a result, the warm air 10 in the store 90 passes through the first duct 40 and is directly supplied to the dry flow passage 17, so that it is discharged to a place other than the dry flow passage 17 as compared with the case where the first duct 40 is not provided. The amount of air 10 can be reduced. In addition, the second duct 41 can reduce the amount of air discharged from the dry flow path 17 other than inside the store 90. As a result, the processing amount of the air 10 increases and the amount of the cooled air 12 supplied to the store 90 increases, so that the temperature rise in the store 90 can be suppressed.

In addition, in the first embodiment, as described above, the indirect vaporization heat exchanger 1 is provided with the third duct 42 that connects the outlet 13b and the air intake port 15a of the condenser 20.

In the second embodiment, as described above, the indirect vaporization heat exchanger 1 includes the vapor compression type air conditioner 110 having the evaporator 120 installed in the store 90 and the condenser 20 installed outdoors. It is installed at 90. The indirect vaporization heat exchanger 1 cools the warm air 10 in the store 90 taken in from the first inlet 10a by the dry flow path 17 and supplies it to the store 90, and wets the air 10 taken in from the second inlet 13a. The air conditioner 200 is configured so that it is cooled to a temperature lower than the outside air temperature by the flow path 16 and supplied to the condenser 20. As a result, the air 10 can be supplied directly from the first inlet 10a and the second inlet 13a to the indirect vaporization heat exchanger 1, so that the amount of air 10 that can be treated increases. Further, since the air 10 can be directly taken in from the first inlet 10a and the air 12 cooled in the dry flow path 17 can be directly supplied to the store 90, when the indirect vaporization heat exchanger 1 is installed outdoors. It is not necessary to provide the provided ducts that respectively connect the first inlet 10a and the outlet 10b of the dry flow path 17 and the store 90. As a result, as compared with the case where the indirect vaporization heat exchanger 1 is installed outside the store 90, more air 10 can be treated, so that the temperature rise in the store 90 can be suppressed. In addition, since it is not necessary to provide a duct at the first inlet 10a or the outlet 10b of the dry flow path 17, the number of parts is greater than that in the case where the indirect vaporization heat exchanger 1 installed outdoors and the store 90 are connected by a duct. Can be suppressed.

The other effects of the second embodiment are similar to those of the first embodiment.

It should be understood that the embodiments disclosed this time are exemplifications in all points and not restrictive. The scope of the present invention is shown not by the above description of the embodiments but by the scope of the claims, and further includes meanings equivalent to the scope of the claims and all modifications (modifications) within the scope.

For example, in the first embodiment described above, the warm air 10 in the store 90 is taken in from the Z1 side of the core portion 2 and the air 11 is caused to flow into the dry flow path 17 toward the Z2 side, and the outside air 13 is taken in from the X1 side to make The example in which the air 11 and the air 14 pass through the indirect vaporization heat exchanger 1 in a direction in which the air 11 and the air 14 face each other has been shown by flowing the air 14 in the wet flow path 16 from the side toward the Z1 side. Not limited. For example, as shown in FIG. 5, by providing the second inlet 13a on the X2 side surface of the indirect vaporization heat exchanger 1, and by providing the outlet 13b on the X1 side surface of the indirect vaporization heat exchanger 1. The air 11 and the air 14 may be substantially orthogonal to each other by causing the air 14 to flow in the wet flow path 16 from the X2 side to the X1 side.

Further, in the first embodiment, the warm air 10 in the store 90 is taken in from the Z1 side of the core portion 2 and the air 11 is caused to flow into the dry flow path 17 toward the Z2 side, and the outside air 13 is taken in from the X1 side to obtain Z2. The example in which the air 11 and the air 14 pass through the indirect vaporization heat exchanger 1 in a direction in which the air 11 and the air 14 face each other has been shown by flowing the air 14 in the wet flow path 16 from the side toward the Z1 side. Not limited. For example, as shown in FIG. 6, the second inlet 13a is provided on the same surface as the first inlet 10a of the indirect vaporization heat exchanger 1, and the X1 side surface of the indirect vaporization heat exchanger 1 (opposite to the outlet 10b). By providing the outlet 13b on the surface (1) to change the direction of the flow of the air 14 from the Z1 side to the Z2 side, the air 11 and the air 14 may proceed in parallel.

Moreover, in the said 1st Embodiment, although the example which connected the outlet 13b and the air intake 15a of the condenser 20 with the 3rd duct 42 was shown, this invention is not restricted to this. For example, as shown in FIG. 7, the outlet of the wet flow path 16 may be provided with an exhaust port 13d. Thereby, the cooled air 15 discharged from the wet flow path 16 is exhausted through the exhaust port 13d and is taken into the condenser 20 from the air intake port 15a of the condenser 20. As a result, since it is not necessary to provide a duct for connecting the indirect vaporization heat exchanger 1 and the condenser 20, it is possible to reduce the number of parts as compared with the case where the indirect vaporization heat exchanger 1 and the condenser 20 are connected by a duct. The increase can be suppressed.

Further, in the above-described first embodiment, an example in which the indirect vaporization heat exchanger 1 is provided outside the store 90 is shown, but the present invention is not limited to this. For example, as shown in FIG. 8, the outlet of the wet flow path 16 is provided with an exhaust port 13d, and the first inlet 10a and the outlet 10b of the indirect vaporization heat exchanger 1 are provided on the wall of the store 90. May be configured to be embedded in. Thereby, the cooled air 15 discharged from the wet flow path 16 is exhausted through the exhaust port 13d and is taken into the condenser 20 from the air intake port 15a of the condenser 20. Further, the warm air 10 in the store 90 is directly taken in from the first inlet 10a, cooled by the dry flow path 17, and supplied to the store 90 through the outlet 10b, so that the indirect vaporization heat exchanger 1 is placed outdoors. It is no longer necessary to provide the ducts that connect the first inlet 10a and the outlet 10b of the dry flow path 17 and the store 90, which are provided in the case of installation in the store. As a result, compared to the case where the indirect vaporization heat exchanger 1 installed outdoors and the store 90 are connected by a duct, and the indirect vaporization heat exchanger 1 and the condenser 20 are connected by a duct, the number of parts is reduced. The increase can be suppressed.

Moreover, in the said 1st Embodiment, although the example which connects the indirect vaporization type heat exchanger 1 and the air intake port 15a of the condenser 20 by the 3rd duct 42 was shown, this invention is not restricted to this. .. For example, as shown in FIG. 9, in the indirect vaporization heat exchanger 1, the air intake port 15b of the condenser 141 and the outlet 13b of the indirect vaporization heat exchanger 1 are connected by the fourth duct 43. But it's okay. The condenser 141 is installed outdoors. A showcase 80 is installed in the store 90, and includes a refrigerator 81. The refrigerator 81 includes an evaporator 140, and the evaporator 140 and the condenser 141 are connected via a refrigerant pipe 140a. Thereby, the air 15 cooled in the wet flow path 16 is exhausted to the condenser 141 through the fourth duct 43, so that the cooling efficiency of the refrigerator 81 can be improved.

Further, in the second embodiment, the example in which the indirect vaporization heat exchanger 1 installed in the store 90 is connected to the condenser 20 installed outdoors via the third duct 42 has been shown. The invention is not limited to this. For example, as shown in FIG. 10, the indirect vaporization heat exchanger 1 provided in the store 90 has an air intake of the condenser 21 of the refrigerator 81 provided in the outlet 13 b and the showcase 80 provided in the store 90. The inlet 15c may be connected by the fifth duct 44. As a result, the air 15 cooled by the wet flow path 16 is exhausted to the condenser 21 via the fifth duct 44. As a result, the cooling efficiency of the condenser 21 can be improved.

In addition, in the second embodiment, an example in which the indirect vaporization heat exchanger 1 and the air intake port 15a of the condenser 20 are connected by the third duct 42 has been shown, but the present invention is not limited to this. .. For example, as shown in FIG. 11, an outlet 13e may be provided at the outlet of the wet flow path 16. As a result, the cooled air 15 discharged from the wet flow path 16 is exhausted through the exhaust port 13e and is taken into the condenser 20 from the air intake port 15a of the condenser 20. As a result, since it is not necessary to provide a duct for connecting the indirect vaporization heat exchanger 1 and the condenser 20, it is possible to reduce the number of parts compared with the case where the indirect vaporization heat exchanger 1 and the condenser 20 are connected by a duct. The increase can be suppressed.

Further, in the above-described second embodiment, an example in which the second inlet 13a of the wet flow path 16 is provided on the same surface as the first inlet 10a of the dry flow path 17 is shown, but the present invention is not limited to this. For example, as shown in FIG. 12, a second inlet 13a may be provided on the outlet side of the dry flow passage 17 so as to take in a part of the air 12 cooled in the dry flow passage 17. Even with such a configuration, the same effect as that of the second embodiment can be obtained.

In the first and second embodiments, the example in which the fan 11a is provided at the inlet of the dry flow passage 17 and the fan 14a is provided at the inlet of the wet flow passage 16 has been shown, but the present invention is not limited to this. For example, a fan may be provided at each of the outlet of the dry flow passage 17 and the outlet of the wet flow passage 16.
