It is an exchange. The mounted state of the heat exchanger unit 1 shown in FIG. 1 is shown up, down, left and right as a normal usage mode when the heat exchanger unit 1 is mounted inside the air conditioner 100. Although the details will be described later, in the present embodiment, the first air means the air supply (SA) which is the air blown out to the air-conditioned space where the air conditioner 100 performs the air conditioning, and the second air is the first air. It is used to cool the air and means the exhaust (EA) which is the air blown out after the actual heat exchange with the first air.

The sensible heat exchanger 10 has a box-shaped outer shell, and is provided with a first path 11 through which the first air flows and a second path 12 through which the second air flows. The first path 11 and the second path 12 in the sensible heat exchanger 10 are composed of a plurality of metal plates having a hollow structure, and each of these metal plates is provided in parallel. The metal plate having the hollow structure may be, for example, one composed of a plurality of fins or a flat tube. For example, the efficiency of sensible heat exchange can be improved by forming the plate with aluminum, copper, or the like, which are metals having good heat transfer properties, or an alloy containing these as main components.

The hollow structure of the metal plates constituting the first path 11 forms each first channel 110 (see FIG. 7) in the first path 11. That is, the first path 11 includes a plurality of first channels 110, and the first air flows through each of the first channels 110. Similarly, the hollow structure of the metal plates constituting the second path 12 forms the respective second channels 120 (see FIG. 7) in the second path 12. That is, the second path 12 includes a plurality of second channels 120, and the second air flows through each of the second channels 120. Alternatively, the second channels 120 of the second path 12 may be formed by gaps between the outer surfaces of the plurality of metal plates arranged side by side to form the first path 11. That is, in the plurality of metal plates constituting the first path 11, the second channel 120 of the second path 12 may be formed by the gap between the adjacent metal plates.

As described above, the first air to be supplied air flows through each of the first channels 110 constituting the first path 11.

That is, the first path 11 communicates the sensible heat exchanger 10 in the left-right direction (horizontal direction), and the second path 12 communicates the sensible heat exchanger 10 in the vertical direction (vertical direction). That is, the first path 11 and the second path 12 are orthogonal to each other. Since the first channel 110 constituting the first path 11 and the second channel 120 constituting the second path 12 are provided alternately side by side with each other, the adjacent first channel 110 and the second channel are adjacent to each other. At 120, sensible heat is exchanged between the first air and the second air. In the present embodiment, it is assumed that the first path 11 and the second path 12 form a orthogonal flow by the first air and the second air, but the present invention is not limited to this. The first path 11 and the second path 12 are provided by the sensible heat exchanger 10 so as to form alternating current, parallel flow, or orthogonal pairing by the first air and the second air. May be good.

Specifically, there is a joint on the upper side of the water receiving portion 14, and water is sent from the inner diameter portion of the joint. As described above, the inlet of the second path 12 is provided on the upper surface of the sensible heat exchanger 10. That is, each of the open ends of the second channels 120 constituting the second path 12 is provided on the upper surface of the sensible heat exchanger 10. Therefore, the water dropped from the water supply body 13 flows into the second channel 120 from each of the opening ends of the second channel 120 constituting the second path 12.

A plurality of ventilation holes 171 (in the example in the drawing, four ventilation holes 171) are provided on the left side surface of the support member 17, and the front surface of the support member 17 is in a grid pattern due to the plurality of ventilation holes 171. Is formed in. The left side surface of the support member 17 provided with the ventilation hole 171 and the left side surface of the sensible heat exchanger 10 where the inlet of the first path 11 is located face in the same direction.

It is separated from the second air flowing into 12.

The second air passes through the ventilation hole 171 provided on the left side surface of the support member 17, and forms the inlet of the second path 12 provided on the upper surface of the sensible heat exchanger 10, that is, the second path 12. It flows into each of the second channels 120 from the open end of each of the channels 120.

The upper surface of the support member 17 includes an area on which the water supply body 13 is placed and an area on which the water supply body 13 is not placed, and the area on which the water supply body 13 is placed is on the right side side. It is provided. The area of the upper surface on which the water supply body 13 is not placed is provided so as to be inclined from the upper edge of the front surface where the ventilation hole 171 is provided so as to be close to the upper surface of the sensible heat exchanger 10.

A configuration example of the water supply body 13 will be described. FIG. 2 is a schematic perspective view showing a configuration example of the water supply body 13 according to the first embodiment. The water supply body 13 has a rectangular shape in a plan view (see FIG. 3), and includes a box body 16 as an outer shell. The water supply body 13 is positioned above the sensible heat exchanger 10 so as to be perpendicular to the path direction of the first path 11. The water supply body 13 is provided so as to be supported above the sensible heat exchanger 10 by being placed on the upper surface of the support member 17 as described above. The area on the upper surface on which the water supply body 13 is placed is provided on the right side side of the support member 17.

That is, the water supply body 13 is provided above the inlet of the second path 12 so as to be biased toward the outlet side of the inlet of the first path 11. In the first path 11 of the sensible heat exchanger 10, the closer to the water supply body 13, the lower the temperature is due to the water supplied from the first tank 71 (see FIG. 8) described later. The temperature of the first air at the inlet of the first path 11 corresponds to the room temperature of the air-conditioned space, and is the highest temperature in the temperature distribution of the first air in the first path 11. On the other hand, by providing the water supply body 13 on the downstream side of the first path 11, that is, on the outlet side of the first path 11, the temperature of the first air and water covers the entire area of the first path 11. The difference can be made large, and the cooling efficiency with respect to the first air can be improved.

FIG. 3 is a schematic plan view showing a configuration example of the water supply body 13. FIG. 4 is a schematic bottom view showing a configuration example of the water supply body 13. FIG. 5 is a schematic side view showing a configuration example of the water supply body 13. The water supply body 13 includes a box body 16 that has a rectangular shape in a plan view and serves as an outer shell, and is made of, for example, resin. The upper surface 161 of the water supply body 13 is provided with a cylindrical water receiving portion 14 and a plurality of ribs 150 extending radially from the water receiving portion 14.

The water receiving portion 14 is provided so as to be biased to one side in the longitudinal direction on the upper surface 161. A second supply channel 82 (see FIG. 8) branched from the supply channel 8 (see FIG. 8) extending from the first tank 71 (see FIG. 8), which will be described later, is communicated with the water receiving unit 14. .. Further, the upper surface 161 has a surface in the vicinity of the water receiving portion 14 formed horizontally, and is inclined downward from a predetermined position toward the rear. In the present embodiment, when viewed from the left side surface 160 as shown in FIG. 5, the upper surface 161 has a planar shape from the front end to the fifth vertical rib 152, and is rearward from the fifth vertical rib 152. It is inclined so that it becomes lower toward the rear to the end. By forming the surface in the vicinity of the water receiving portion 14 horizontally, the water dropped in the center of the water receiving portion 14 draws concentric circles and is evenly distributed to each flow channel 15. Further, since the water is inclined from a position away from the water receiving portion 14, the separated water flows into each of the second channels 120 without staying in the flowing water channel 15. As shown in FIG. 3, since the flow path width of the water flow channel 15 is formed to be wider as the distance from the water receiving portion 14 is increased, when the upper surface 161 is a horizontal plane, the flow velocity of the divided water becomes gentler as it goes downstream. It is conceivable that it will become. However, since the upper surface 161 has an inclination, it is possible to flow the separated water into each of the second channels 120 without impairing the flow velocity.

The water supplied from the second supply channel 82 is received by the water receiving unit 14, and then is divided along a plurality of ribs 150 radially extending from the water receiving unit 14, and the separated water exchanges sensible heat. It is dropped inside the second path 12 of the vessel 10. That is, the water supply body 13 functions as a sprinkler unit for sprinkling the water supplied from the first tank 71 to each of the plurality of second channels 120 constituting the second path 12 of the sensible heat exchanger 10.

The plurality of ribs 150 extending radially from the outer peripheral surface of the water receiving portion 14 are provided at equal intervals, and the pitch is, for example, 6 mm. By forming the pitches at equal intervals, the effect of evenly splitting can be enhanced. Each of the plurality of ribs 150 is bent one or more times from the water receiving portion 14 toward the edge on the long side of the upper surface 161 to form an L-shape, a U-shape (C-shape), or a crank shape. It is formed.

In the plurality of ribs 150 extending radially from the water receiving portion 14, the water flow channel 15 is formed by the grooves formed by the two adjacent ribs 150. That is, each of the flow channels 15 on the upper surface 161 of the water supply body 13 is composed of grooves formed by two adjacent ribs 150 provided on the upper surface 161 of the water supply body 13. The water received by the water receiving portion 14 flows toward the long side edge portion on the upper surface 161 along the flow channel 15, that is, the groove formed by the two adjacent ribs 150.

The angles of the two adjacent ribs 150 are set to be equal in all of the plurality of ribs 150 extending from the outer peripheral surface of the water receiving portion 14. Therefore, when the water received by the water receiving unit 14 is sprinkled and distributed to each of the flowing water channels 15, it is possible to suppress a large difference in the amount of distributed water in each of the flowing water channels 15.

Each of the plurality of ribs 150 is branched into two parallel ribs 150 at a point close to the edge on the long side of the upper surface 161. That is, the plurality of ribs 150 extend from the water receiving portion 14 which is the base end to the edge portion on the long side side of the upper surface 161 and have two at the end portion 151 located at a point close to the edge portion. Branches to. From each of the ends 151 of the bifurcated ribs 150, the water supply body 13 is bent from the upper surface 161 toward the side surface 160, and extends as vertical ribs 152 from above to below the side surface 160. .. That is, the vertical rib 152 is composed of a pair of two parallel ribs extending vertically on the side surface 160 of the water supply body 13.

On the upper surface 161 of the water supply body 13, a V-shaped notch 162 is provided on the side opposite to the short side on the side where the water receiving portion 14 is provided. A part of the ribs 150 extending from the water receiving portion 14 toward the side of the short side provided with the V-shaped notch portion 162 is formed by the V-shaped notch portion 162. It is bent toward the inner wall surface and extends as a vertical rib 152 from the upper side to the lower side of the inner wall surface.

The vertical ribs 152, which are two parallel ribs provided on the inner wall surface formed by the side surfaces 160 on the long side and the V-shaped notch 162, are arranged at equal intervals in the front-rear direction. It is arranged side by side on the inner wall surface formed by the side surface 160 and the V-shaped notch portion 162. In each of the side surfaces 160 on the long side, the vertical ribs 152 provided on one side surface 160 and the vertical ribs 152 provided on the other side surface 160 are staggered so as not to overlap in a side view. It is provided. That is, as an example, in the left side view shown in FIG. 5, a vertical rib provided on the other side surface 160 is provided between the vertical rib 152 provided on one side surface 160 and the vertical rib 152 adjacent to the vertical rib 152. Vertical ribs 152 on each side surface 160 are provided such that 152 is located. Similarly, in the inner wall surface formed by the V-shaped notch portion 162, the vertical ribs 152 provided on the inner wall surfaces facing each other are provided in a staggered manner.

By providing the vertical ribs 152 on one side surface 160 and the other side surface 160 in this way, the vertical ribs 152 can be provided on the upstream side and the downstream side in the second air flow direction. As described above, since the vertical ribs 152 are provided in a staggered manner on one side surface 160 and the other side surface 160, the upstream side and the downstream side in the second air flow direction have different second channels 120. Water can be dropped toward the water, the distribution of the water dropping points from the water supply body 13 is biased, the occurrence of deviation in the temperature distribution is suppressed, and the water is efficiently dropped into the second path 12. Can be done. For example, the vertical ribs 152 of each side surface 160 are provided so as to be evenly spaced when arranged in a row in the front-rear direction. As a result, water can be dropped at equal intervals, and the cooling efficiency is improved.

FIG. 6 is an explanatory diagram schematically showing the air flow in the heat exchanger unit 1. FIG. 7 is an explanatory diagram illustrating a main part of the water supply body 13 in the heat exchanger unit 1. In FIG. 7, only a part of the sensible heat exchanger 10 is shown. The first air and the second air flow from the same side surface side (left side side side) of the heat exchanger unit 1 toward the heat exchanger unit 1. As described above, the first air flows into the inside of the sensible heat exchanger 10 from the inlet of the first path 11 located on the left side surface of the sensible heat exchanger 10, that is, the opening end of each of the first channels 110. The second air passes through the ventilation hole 171 formed on the left side surface of the support member 17 provided so as to cover the upper surface of the sensible heat exchanger 10, and then the second path located on the upper surface of the sensible heat exchanger 10. It flows into the inside of the sensible heat exchanger 10 from the inlet of 12, that is, the open end of each of the second channels 120. The arrow representing the second air in FIG. 6 indicates that the second air flows in from the inlet of the second path 12 on the upper surface of the sensible heat exchanger 10 and flows downward, and is on the lower surface of the sensible heat exchanger 10. It shows how the second air flows out from the outlet of the two paths 12 and flows backward.

There is. The water supply body 13 is placed on the upper part of the sensible heat exchanger 10 so that the tips of the two ribs constituting the vertical rib 152 overlap with the opening ends of the second channels 120, respectively. The distance between the two ribs forming the vertical rib 152 is made larger than the pitch width of the first channel 110 forming the first path 11. Therefore, the water supply body 13 is placed on the upper part of the sensible heat exchanger 10 so that the first channels 110 forming the first path 11 are located between the two ribs forming the vertical ribs 152. There is.

Water flowing downward from the upper surface 161 of the water supply body 13 along the inner wall surface formed by the side surface 160 or the V-shaped notch 162 travels on the outer surface side of the two ribs constituting the vertical rib 152. And run down. Since each of the two ribs constituting the vertical rib 152 is located at the opening end of each of the adjacent second channel 120 in the plurality of second channels 120 constituting the second path 12, the vertical rib 152 is formed. The water flowing down along the outer surface side of the second channel 120 can be dropped onto the opening end of each of the second channels 120.

The number of vertical ribs 152 that can be formed on the side surface 160 is also limited in order to secure the pitch between the ribs 150 provided on the upper surface 161. Therefore, on the side of one side surface 160, a second path 12 in which water is not dropped is generated. On the other hand, since the vertical ribs 152 provided on each side surface 160 are formed in a staggered pattern, the other side surface 160 is opposed to the second path 12 where water is not dropped on one side surface 160 side. Water can be dropped on the second path 12 by the vertical rib 152 provided in the second path 12. Similarly, in each of the inner wall surfaces formed by the V-shaped notch 162, water can be dropped into each of the corresponding second paths 12 by the vertical ribs 152 provided in a staggered manner. With the vertical ribs 152 provided in a staggered manner in this way, the pitch between the ribs 150 provided on the upper surface 161 is sufficiently secured, and all the second paths 12 in the sensible heat exchanger 10 are connected from the first tank 71. The supplied water can be dropped to improve the cooling capacity of the sensible heat exchanger 10.

The vaporization filter 21 is provided in the first path 11, and is provided between the sensible heat exchanger 10 and the first fan 61.

The vaporization filter 21 is provided with one surface of a rectangular filter element facing the side surface of the sensible heat exchanger 10 provided with the outlet of the first path 11. The first flow path 41 from the vaporization filter 21 to the first outlet 4 extends upward from the vaporization filter 21.

The first tank 71 forms, for example, a rectangular box having an opening formed in the upper portion thereof, and is provided below the vaporization filter 21 and the drain pan 103.

The recovered water is stored in the first tank 71 via a recovery channel 9 for recovering the water remaining in the cooling unit 2. The recovery channel 9 includes a first recovery channel 91 and a second recovery channel 92. The first tank 71 and the vaporization filter 21 communicate with each other via the first recovery water channel 91. The first tank 71 and the drain pan 103 are communicated with each other via the second recovery water channel 92. The ends of the first recovery channel 91 and the second recovery channel 92 on the first tank 71 side, that is, the outlets of the first recovery channel 91 and the second recovery channel 92 are directed to the opening of the first tank 71. The details will be described later, but the water remaining in the cooling unit 2 is the water supplied from the first tank 71 to the vaporization filter 21 and the heat exchanger unit 1, and is the water remaining in a liquid state without vaporization. be.

Inside the first tank 71, a pump 101 for supplying the water stored in the first tank 71 to the vaporization filter 21 and the heat exchanger unit 1 is provided. The pump 101 is not limited to the case where it is provided inside the first tank 71, but the main body of the pump 101 is provided outside the first tank 71, and the pump 101 is provided via a water channel communicating the pump 101 and the first tank 71. It may convey the water in the first tank 71.

The pump 101 is connected to a controller 102 composed of, for example, a microcomputer or the like by a communication line, and is driven or stopped based on a control signal output from the controller 102. In the figure, the controller 102 is shown as being provided at the lower part of the air conditioner 100, but the present invention is not limited to this. The controller 102 is provided, for example, on the outer peripheral surface side of the flow path wall forming the second flow path 51 from the sensible heat exchanger 10 to the second air outlet 5, and the flow path wall of the second flow path 51 is provided. It may be cooled by the second air through the air.

The pump 101, the vaporization filter 21, and the sensible heat exchanger 10 are communicated with each other by the supply water channel 8. Therefore, the first tank 71, the vaporization filter 21, and the sensible heat exchanger 10 communicate with each other via the pump 101 and the supply water channel 8. The supply channel 8 includes a first supply channel 81 and a second recovery channel 92, and is branched into a first supply channel 81 and a second recovery channel 92 in the vicinity of the vaporization filter 21 and the sensible heat exchanger 10. The first supply water channel 81 communicates with the vaporization filter 21. The second supply water channel 82 communicates with the sensible heat exchanger 10.

The water supplied from the first supply water channel 81 is temporarily retained by the first water supply unit 211 provided in the upper part of the vaporization filter 21, and is once supplied to the vaporization filter 21 from the water supply hole 212 provided in the first water supply unit 211. It is dropped and penetrates into the vaporization filter 21. The water supplied from the second supply water channel 82 is dropped into the inside of the second path 12 of the sensible heat exchanger 10 via the water supply body 13 provided in the upper part of the sensible heat exchanger 10.

It was conveyed from the first tank 71 to the vaporization filter 21 and the sensible heat exchanger 10 by the pump 101 provided in the first tank 71, and was not vaporized by the vaporization filter 21 and the sensible heat exchanger 10 and remained in a liquid state. The water is returned to the first tank 71 by gravity. That is, a water circulation channel is formed by the first tank 71, the supply channel 8, the cooling unit 2, and the recovery channel 9.

The supply water channel 8 is branched into a first supply water channel 81 and a second supply water channel 82 according to the vaporization filter 21 and the heat exchanger unit 1 included in the cooling unit 2. The recovery water channel 9 includes a first recovery water channel 91 and a second recovery water channel 92 according to the vaporization filter 21 and the heat exchanger unit 1 included in the cooling unit 2. Therefore, the circulation water channels include the vaporization filter 21 system water channel by the first supply water channel 81, the vaporization filter 21 and the first recovery water channel 91, the second supply water channel 82, the second path 12 of the heat exchanger unit 1, and the second recovery water channel. Includes a water channel configured in parallel with the heat exchanger unit 1 system water channel according to 92.

In the volume flow rate per unit time of the water conveyed by the drive of the pump 101, the volumetric flow rate of the first supply water channel 81, which is the vaporization filter 21 system water channel, is the volume flow rate of the second supply water channel 82, which is the heat exchanger unit 1 system water channel. It is less than the volumetric flow rate. For example, the volumetric flow rate of the first supply channel 81 is 0.3 L / min, the volumetric flow rate of the second supply channel 82 is 3 L / min, and the volumetric flow rate of the first supply channel 81 is the volumetric flow rate of the second supply channel 82. It may be 1/10 of the above. As a result, it is possible to increase the amount of water for cooling the second air by sensible heat in the sensible heat exchanger 10 while suppressing the amount of water vapor blown out to the air-conditioned space together with the first air, and the cooling unit 2 The cooling efficiency in the above can be further improved.

The air conditioner 100 sucks the air in the air-conditioned space from the suction port 3, and the sucked air passes through the suction flow path 32 and the dust collection filter 31 and flows into the heat exchanger unit 1. Corresponding to the outlet of the suction flow path 32, the inlets of the first path 11 (SA: air supply side path) and the second path 12 (EA: exhaust side path) of the heat exchanger unit 1 are the heat exchanger unit 1. The suction air is divided into a first air (SA) flowing through the first path 11 and a second air (EA) flowing through the second path 12.

Water supplied from the first tank 71 is dropped onto the second path 12 via the water supply body 13 provided above the sensible heat exchanger 10. That is, in the second path 12, the second air and the water dropped from the water supply body 13 are mixed. The water stored in the first tank 71 is the water recovered from the vaporization filter 21 and is cooled by the heat of vaporization. Therefore, the water temperature of the water supplied from the first tank 71 is lower than the temperature of the second air immediately after flowing into the second path 12. The second air exchanges heat with the water dropped from the water supply body 13. That is, it is cooled by the water. Further, as described above, the water dropped from the water supply body 13 is distributed to each of the second channels 120 constituting the second path 12, and is dropped into the inside of the second channel 120, so that the water is in contact with the second air. Surface area increases. As a result, a part of the water dropped from the water supply body 13 is vaporized, and the second air is also cooled by the heat of vaporization.

The first air flowing through the first path 11 of the sensible heat exchanger 10 and the second air flowing through the second path 12 form a direct flow, and sensible heat is generated between the first air and the second air. It will be exchanged. As described above, the second air flowing through the second path 12 is cooled by the water supplied from the first tank 71, and the first air is cooled by the water supplied from the first tank 71. It is cooled by air.

The first air that has passed through the first path 11 of the sensible heat exchanger 10 flows into the first flow path 41 from the sensible heat exchanger 10 to the first outlet 4. In the first flow path 41, a vaporization filter 21 is provided on the downstream side of the sensible heat exchanger 10, and the first air passes through the vaporization filter 21.

Water supplied from the first tank 71 is dropped onto the vaporization filter 21 via the first water supply unit 211 provided above the vaporization filter 21. Since the inside of the first flow path 41 is maintained at a negative pressure, the water supplied from the first tank 71 is sucked into the inside of the vaporization filter 21 from the water supply hole 212 provided on the bottom surface of the first water supply unit 211. , Penetrates into the vaporization filter 21. The water that has permeated the vaporization filter 21 is vaporized by the passage of the first air through the vaporization filter 21, and is vaporized, that is, evaporated to become water vapor and contained in the first air. The heat of vaporization cools the first air and lowers the temperature of the first air. The cooled first air is blown out from the first outlet 4 by the first fan 61 into the air-conditioned space as supply air (SA).

With such a configuration, the first air blown out to the air-conditioned space as air supply (SA) has two stages including primary cooling by the sensible heat exchanger 10 and secondary cooling by the vaporization filter 21. Cooling can be done. Therefore, for example, the temperature of the first air can be further lowered as compared with the direct vaporization method using only the vaporization filter 21. At this time, the first water supply unit 211 may be replaced with the water supply body 13.

The second air that has flowed into the second path 12 of the sensible heat exchanger 10 is mixed with the water that has been dropped from the water supply body 13 and supplied to the outlet of the second path 12 located below the sensible heat exchanger 10. It is transported toward. Since the second path 12 extends from the upper side to the lower side of the sensible heat exchanger 10 in the region where the direct flow with the first path 11 is formed, the water supplied from the water supply body 13 is mixed. The generated second air flows from the upper side to the lower side of the sensible heat exchanger 10.

A drain pan 103 is provided on the downstream side of the outlet of the second path 12 of the sensible heat exchanger 10, and the second flow path 51 from the drain pan 103 to the second outlet 5 is directed upward from the drain pan 103. It has been extended. The second flow path 51 is formed in the rear direction, which is the depth direction of FIG. Therefore, the second air mixed with the water supplied from the water supply body 13 flows out from the outlet of the second path 12 of the heat exchanger 10, and then is folded up and down with the point where the drain pan 103 is located as the lowest point. It will flow. That is, the second flow path 51 including the second path 12 of the sensible heat exchanger 10 extends downward from above the sensible heat exchanger 10, passes through the place where the drain pan 103 is located, and then extends upward. Includes a folded part in the vertical direction.

Centrifugal force is generated when the second air mixed with the water supplied from the water supply body 13 passes through the folded-back portion, that is, changes from the downward flow direction to the upward flow direction. Since the water flowing together with the second air has a higher specific gravity than the air, it is separated from the second air, that is, gas-liquid separated by being biased toward the outer peripheral side of the folded-back portion by centrifugal force.

The water separated from the second air (gas-liquid separation) is temporarily retained in the drain pan 103, and is recovered in the first tank 71 via the second recovery water channel 92 provided in the lower part of the drain pan 103. The water adhering to the inner wall surface of the second path 12 of the sensible heat exchanger 10 also moves to the outlet of the second path 12 due to gravity, and by dropping from the outlet, the water is retained in the drain pan 103 and recovered second. It is collected in the first tank 71 via the water channel 92.

A portion of the sensible heat exchanger 10 extending upward from above in the second path 12, a drain pan 103 provided below the outlet of the second path 12, and a second extending upward from the drain pan 103. The flow path 51 constitutes a gas-liquid separation mechanism that separates the water from the second air mixed with the water supplied from the water supply body 13. By separating water from the second air by the gas-liquid separation mechanism, it is possible to suppress an increase in the absolute humidity of the second air.

The second air that has passed through the drain pan 103 flows into the second flow path 51 from the drain pan 103 to the second outlet 5. The second flow path 51 is provided between, for example, the side surface of the sensible heat exchanger 10 and the inner surface of the housing 104 facing the side surface, and the second air flows through the second flow path 51. , The drain pan 103 is conveyed to the fan chamber in which the fan motor 6 and the second fan 62 are placed. That is, since the fan motor 6 is provided in the middle of the second flow path 51, it is cooled by the second air. Since the fan motor 6 is provided on the downstream side of the gas-liquid separation mechanism, the fan motor 6 can be efficiently cooled by the second air after the water is separated. The second air that has cooled the fan motor 6 is blown out as exhaust from the second outlet 5.

As shown in this embodiment, by using an air conditioner equipped with a heat exchanger unit 1 including a water supply body and a heat exchanger, the second air cooled by the water supplied to the heat exchanger can be used. The cooled first air can be blown out to the air-conditioned space as supply air.
