  The problem in the conventional example is that the room temperature rises during the dehumidifying operation, so that the comfort is lacking.

  That is, in the conventional product, when dehumidifying the room, the heat pump first converts the refrigerant into a high-temperature and high-pressure gas state with a compressor, the refrigerant flows to the radiator, applies air to the radiator, and dissipates heat. By cooling the cooler, the refrigerant is deprived of heat and liquefied. Next, the refrigerant liquefied by the radiator is brought into a gas-liquid two-phase state by lowering the pressure by the expansion means. Let the refrigerant in the state flow to the heat absorber. Since the heat absorber is cooled, if indoor air is applied to the heat absorber, it can be condensed and dehumidified. Here, in order to increase the dehumidifying efficiency in the heat absorber, it is necessary that the radiator is cooled efficiently, but the temperature of the cooling air generated by cooling the radiator increases and is released into the room. For example, during the rainy season when dehumidification is performed, the indoor temperature rises due to the increased cooling air, which is not comfortable.

  Therefore, the present invention aims to improve comfort.

In order to achieve this object, the present invention includes a main body case that has an intake port and first, second, and third exhaust ports and is installed indoors, and a heat pump that is provided in the main body case. The heat pump is formed by a compressor and a radiator, an expansion unit, and a heat absorber sequentially provided downstream of the compressor, and the air sucked into the main body case from the intake port is passed through the heat absorber. A first blower for blowing air to the first exhaust port, and air sucked into the main body case from the intake port to the second exhaust port or the third exhaust port via the radiator; A second air supply means for supplying air is provided, the first and second exhaust ports communicate with the main body case and the room, and the third exhaust port communicates with the main body case and the outdoors. Between the air inlet and the radiator. Air path switching means for switching the air path from the air intake port into the main body case to the second exhaust port or the third exhaust port via the radiator, Drain water supply means for supplying the dew condensation water generated in the heat absorber to the radiator is provided, thereby achieving the intended purpose.

  As described above, the present invention includes an air inlet, a first, second, and third air outlet, a main body case installed indoors, and a heat pump provided in the main body case. Is formed by a compressor and a radiator, an expansion means, and a heat sink sequentially provided downstream of the compressor, and the air exhausted into the main body case from the air inlet through the heat absorber A first air blowing means for blowing air to the opening, and a second air for blowing the air sucked into the main body case from the intake opening to the second exhaust opening or the third exhaust opening through the radiator. The first and second exhaust ports communicate with the main body case and the room, and the third exhaust port includes communication means for communicating the main body case and the outside. Humidification means is provided between the air inlet and the radiator, Air path switching means for switching the air path from the air inlet into the main body case to the second exhaust port or the third exhaust port via the radiator is generated in the heat absorber. Since the drain water supply means for flowing the condensed water to the radiator is provided, the rise in the room temperature can be reduced and the dehumidification efficiency can be improved. As a result, the comfort can be improved. is there.

  That is, in the dehumidifying operation, first, the refrigerant is brought into a high-temperature and high-pressure gaseous state by the compressor, the refrigerant flows to the radiator, and by cooling the radiator, the refrigerant is deprived of heat and then liquefied. The refrigerant liquefied by the radiator is brought into a gas-liquid two-phase state by lowering the pressure by the expansion means. Finally, the refrigerant in the gas-liquid two-phase state is passed through the heat absorber, and the room air is condensed on the heat absorber. By dehydrating, it is dehumidified. Here, when the refrigerant is cooled by the radiator, air is applied to the radiator and the radiator is cooled by the condensed water generated by the heat absorber. Here, the air that has cooled the radiator is exhausted to the outside from the third exhaust port via the communication means.

  That is, the rise in the room temperature can be reduced and the dehumidification efficiency can be improved. As a result, the comfort can be improved.

The refrigerant flowing from the bottom flows from the lower part to the upper part of the heat absorber 13.

  As shown in FIG. 2, the air sucked into the main body case 1 from the air inlet 2 by the air blowing means 18 is blown to the air outlet 3 through the air purifying filter 7 a as the air purifying means 7 and the heat absorber 13 in order. Then, the air sucked into the main body case 1 from the air inlet 2 by the air blowing means 19 passes through the air purifying filter 7a as the air purifying means 7, the humidifying means 21, and the radiator 11 in this order to the exhaust port 4 or the exhaust port 5. It is to be blown into. Switching of the air path to the exhaust port 4 or the exhaust port 5 is performed by the air path switching unit 20, and the air path switching unit 20 is provided between the exhaust port 4, the exhaust port 5, and the air blowing unit 19. It is provided in the air passage.

  The air blowing means 18 is an air path between the heat absorber 13 and the exhaust port 3, faces the heat absorber 13, and is located closer to one side surface of the main body case of the heat absorber 13. The air path between the exhaust port 4 and the exhaust port 5 faces the radiator 11 and is located closer to the other side surface of the main body case of the radiator 11.

  The humidifying means 21 is located between the radiator 11 and the air blowing means 19 and has a water storage case 22 containing a certain amount of water, and a disk-shaped part in which a part of the peripheral edge is immersed in the water of the water storage case 22. The humidifying filter 23 and a water supply unit 24 that pumps water from the water storage case 22 to the humidifying filter 23 and supplies the water are formed.

  With the above configuration, a humidifying operation and a dehumidifying operation are performed.

  First, in the humidifying operation, the heat pump 6 and the air blowing means 18 are stopped, the air path switching means 20 switches the air path to the exhaust port 4, and the air blowing means 19 sucks air into the main body case 1 from the air inlet 2. The blown air is blown from the exhaust port 4 into the room through the radiator 11 and the humidifying filter 23. That is, the humidifying filter 23 which is the humidifying means 21 contains the water of the water storage case 22, so that this water gives moisture to the air blown by the blower means 19, and the air containing the moisture causes the room to pass through the room. It is to be humidified.

  Here, the humidifying means 21 will be described in detail. As shown in FIGS. 3 and 4, the humidifying means 21 includes a water storage case 22 containing a certain amount of water, and a part of the peripheral portion immersed in the water of the water storage case 22. The disk-shaped humidification filter 23 is included, and a water supply unit 24 that pumps water from the water storage case 22 into the humidification filter 23 and supplies the water. Specifically, the water storage case 22 has a substantially box shape with an upper surface opened and contains a certain amount of water supplied from a water supply tank (not shown). The water storage case 22 is rotatable. The water supply part 24 is installed in. The water supply section 24 is formed of a first frame body section 25, a second frame body section 26, and a water supply case section 27. The first frame body 25 has a disc shape and is provided with a rotation shaft portion 28 serving as a center of rotation at the center portion and a plurality of water supply case fixing portions 29 for fixing the water supply case portion at the peripheral portion. The rotating shaft portion 28 and the plurality of water supply case fixing portions 29 are connected to each other by linear and circular beam portions 30. The second frame body portion 26 has a disk shape, and a rotation shaft portion 31 that is a center of rotation is provided at the center portion, and a cylindrical shape that fits with the peripheral edge portion of the first frame body portion 25 at the peripheral edge portion. The peripheral holding part 32 is provided, and the rotating shaft part 31 and the peripheral holding part 32 are connected by a linear and circular bar part 33. The water supply case portion 27 has a substantially box shape having an opening 34 that is open on one side, and is fixed to a water supply case fixing portion 29 of the first frame body portion 25, and the first frame body portion 25 is a rotating shaft portion. By rotating about 28, the water in the water storage case 22 is pumped up at the lowest point, and water is supplied to the humidifying filter 23 at the highest point. Further, the humidifying filter 23 has a disc shape formed of a plurality of fibers, and is fixed between the first frame body portion 25 and the second frame body portion 26.

  With such a configuration, the humidifying filter 23 is fixed between the first frame body part 25 to which the plurality of water supply case parts 27 that are the water supply parts 24 are fixed and the second frame body part 26 that is the water supply part 24. Then, by rotating by a rotating means (not shown), the water supply case part 27 pumps up the water in the water storage case 22 at the lowest point, and the water in the water supply case part 27 is supplied to the humidifying filter 23 at the highest point. Water is poured and water is supplied.

  A feature of the present embodiment is that a drain water supply means 8 is provided for flowing condensed water generated in the heat absorber 13 to the radiator 11 during the dehumidifying operation, and the radiator 11 is cooled by the condensed water.

  That is, in the dehumidifying operation, the heat pump 6 is operated, and the air sucked into the main body case 1 from the air inlet 2 by the air blowing means 18 passes through the air purifying filter 7a, which is the air purifying means 7, and the heat absorber 13 sequentially. The air is blown to the exhaust port 3. Here, the air blown to the heat absorber 13 is dehumidified by dew condensation in the heat absorber 13, and the dehumidified air is blown into the room to dehumidify the room. On the other hand, the air sucked into the main body case 1 from the air inlet 2 by the air blowing means 19 is blown to the air outlet 5 through the radiator 11 and the humidifying filter 23. In this way, the air blower 19 applies air to the radiator 11 to cool the radiator 11, and also provides the drain water supply means 8 for flowing the condensed water generated in the heat absorber 13 to the radiator 11. The radiator 11 is cooled (described in detail later with reference to FIGS. 2 and 4). Thus, the dehumidification efficiency can be improved by increasing the cooling efficiency of the radiator 11.

  Further, the air that has cooled the radiator 11 is exhausted from the exhaust port 5 to the outside through the communication unit 9 by switching the air path to the exhaust port 5 by the air path switching unit 20. Can be reduced.

  As a result, it is possible to reduce the rise in the room temperature and improve the dehumidification efficiency.

  As shown in FIGS. 5 and 6, the heat absorber 13 is located above the radiator 11, and the drain water supply means 8 is located between the heat absorber 13 and the radiator 11. is there. The drain water supply means 8 is configured to supply the dew condensation water generated by the heat absorber 13 to the windward side of the radiator 11. Specifically, the drain water supply means 8 has a substantially box shape, and includes a first opening 35 on the upper surface and a second opening 36 on the lower side of the windward leeward side, and the first opening 35. Is configured to cover the lower surface of the heat absorber 13. That is, the drain water supply means 8 includes a substantially horizontally long first rectangular opening 35 that covers the bottom surface of the heat absorber on the substantially horizontally long upper surface of the box, and the wind path leeward side surface. In the lower part, a second opening 36 having a substantially horizontally long square shape opened to the upper windward side of the radiator 11 is provided. Here, the dew condensation water generated in the heat absorber 13 is dropped from the lower surface of the heat absorber 13 into the drain water supply means 8 through the first opening 35. The dripped dew condensation water flows down from the drain water supply means 8 to the upper windward side of the radiator 11 through the second opening 36.

  That is, since the heat absorber 13 is located at the upper part of the radiator 11 and the drain water supply means 8 is located between the heat absorber 13 and the radiator 11, the drain water generated in the heat absorber 13 is reduced by gravity. It can be supplied to the radiator 11. Further, since the drain water supply means 8 supplies the dew condensation water generated by the heat absorber 13 to the windward side of the radiator 11, the dew condensation water supplied to the heat radiator 11 flows from the upper part to the lower part of the radiator 11. The heat sink 11 flows down while cooling. Here, there is a distance from the windward side to the leeward side of the radiator 11 even if the condensed water supplied to the radiator 11 by the blowing of the blowing unit 19 flows to the blowing unit 19 side. It is possible to suppress suction from the leeward side of the radiator 11 into the blower means 19 while the radiator 11 flows down while cooling from the bottom to the bottom. Further, the drain water supply means 8 has a substantially box shape, and includes a first opening 35 on the upper surface and a second opening 36 on the lower side of the wind path leeward side. Since the opening is provided so as to cover the lower surface of the heat absorber 13, the drain water generated in the heat absorber 13 is not dripped to the outside of the drain water supply means 8, and is drained through the first opening 35. It can be led to the water supply means 8.

  Moreover, the lower surface 37 of the drain water supply means 8 is configured to be inclined toward the radiator 11 side. Thereby, the dew condensation water generated in the heat absorber 13 is dropped into the drain water supply means 8 from the lower surface of the heat absorber 13 through the first opening 35. The dripped dew condensation water flows along the lower surface 37 inclined toward the radiator 11 in the drain water supply means 8 and flows down to the upper windward side of the radiator 11 through the second opening 36. . In other words, since the lower surface 37 of the drain water supply means 8 is inclined toward the radiator 11, the dew condensation water dripped into the drain water supply means 8 can be easily flowed to the second opening 36.

  Further, as shown in FIG. 2, the length of the heat sink 11 in the main body case 1 in the left-right direction is substantially the same as the length of the heat sink 13 in the left-right direction, and the left and right ends are substantially vertical. It is what is located. Specifically, the heat radiator 11 and the heat absorber 13 have a substantially horizontally long rectangular parallelepiped shape, and the length in the left-right direction in the main body case 1 is substantially the same. The left and right end portions of the vessel 13 are positioned on a substantially straight line. That is, when the drain water generated in the heat absorber 13 flows into the radiator 11 via the drain water supply means 8, the drain water generated in the left side portion of the heat absorber 13 when viewed from the front side of the main body case 1. Flows to the left side of the radiator 11, drain water generated at the right side of the heat absorber 13 flows to the right side of the radiator 11, and drain water generated at the center of the heat absorber 13 flows to the center of the radiator 11. It is flowing. That is, the drain water generated by the heat absorber 13 can be uniformly supplied to the entire radiator 11.

  The heat absorber 13 is formed of a bellows-like conduit portion 16 and a plurality of fin portions 17 fixed to the conduit portion 16, and the fin portions 17 are substantially vertically long rectangular shapes and extend in the vertical direction. It is. Specifically, a plurality of fin portions 17 having a substantially vertically long rectangular shape extending in the vertical direction, and penetrating through the plurality of fin portions 17, and a predetermined horizontal direction between the surfaces of adjacent fin portions 17. The straight pipe part 38 that extends in the horizontal direction, which is the fixed pipe part 16 having the above-described space, and the curved curved pipe part 39 that is the conduit part 16 that connects the straight pipe part 38 are formed.

  That is, the dew condensation water generated at the fin portion 17 of the heat absorber 13 flows down to the lower portion of the fin portion 17 along the fin portion 17 extending in the vertical direction in a substantially vertically rectangular shape. The generated condensed water can be collected in the drain water supply means 8 through the fin portion 17.

  The radiator 11 is formed of a bellows-like conduit portion 14 and a plurality of fin portions 15 fixed to the conduit portion 14, and the fin portions 15 are substantially vertically long and extend in the vertical direction. It is. Specifically, a predetermined space in the horizontal direction is formed between the plurality of fin portions 15 that extend in the vertical direction in a substantially vertically long rectangular shape and the surfaces of the adjacent fin portions 15 while penetrating through the plurality of fin portions 15. The straight pipe part 40 which is a fixed and horizontally extending conduit part 14 and the curved bent pipe part 41 which is the conduit part 14 connecting the straight pipe part 40 are formed.

  That is, the dew condensation water generated at the fin portion 15 of the heat absorber 13 and dripped into the drain water supply means 8 extends along the fin portion 15 of the radiator 11 extending in the vertical direction in a substantially vertical rectangular shape. Therefore, the entire fin portion 15 of the radiator 11 can be cooled from the upper portion to the lower portion of the radiator 11.

  Further, the opening area of the second opening 36 is smaller than the opening area of the first opening 35. Thereby, the air sucked into the main body case 1 from the air inlet 2 by the air blowing means 18 flows into the heat absorber 13 through the air purifying filter 7a which is the air purifying means 7, and the air flowing into the heat absorber 13 is The air that flows into the radiator 11 side through the drain water supply means 8 by the air blowing means 19 or the air that has been sucked into the main body case 1 from the air inlet 2 by the air blowing means 19 is the air that is the air purifying means 7. The air flowing into the radiator 11 through the clean filter 7a and the air flowing into the radiator 11 can be reduced from flowing into the heat absorber 13 through the drain water supply unit 8 by the blower unit 18.

  Moreover, the 2nd opening part 36 of the drain water supply means 8 is a substantially horizontally long square shape, and this peripheral part and the fin part 15 of the heat radiator 11 are contacting. Specifically, the second opening 36 of the drain water supply means 8 has a substantially horizontally long rectangular shape opened to the upper windward side of the radiator 11, and the upper windward side of the peripheral portion and the fin portion 15 of the radiator 11. Are in contact with the ends of the.

  That is, the dew condensation water generated in the heat absorber 13 is dropped from the lower surface of the heat absorber 13 into the drain water supply means 8 through the first opening 35, and this dripped dew condensation water is the drain water supply means 8. It flows from the inside to the second opening 36. Here, for example, if the peripheral edge portion of the second opening 36 of the drain water supply means 8 and the fin portion 15 of the radiator 11 are not in contact with each other, the dew condensation water in the drain water supply means 8 is the second opening. A water film is formed by the portion 36, and it becomes difficult to flow from the second opening 36 to the radiator 11. Therefore, a water film is formed at the second opening 36 by bringing the peripheral edge of the second opening 36 of the drain water supply means 8 and the upper windward end of the fin portion 15 of the radiator 11 into contact with each other. However, since this water film is in contact with the upper windward end of the fin portion 15 of the radiator 11, the water film can easily flow along the fin portion 15 of the radiator 11 from the second opening 36. .

  Moreover, the length of the fin part 15 of the heat radiator 11 in the vertical direction is longer than the length of the fin part 17 of the heat absorber 13 in the vertical direction, and the length of the fin part 15 of the heat radiator 11 in the main body case 1 is The fin portion 17 of the heat absorber 13 is configured to be shorter than the length of the main body case 1 in the front-rear direction. Specifically, the fin portion 15 of the radiator 11 and the fin portion 17 of the heat absorber 13 are substantially vertically rectangular and have substantially the same surface area, but the vertical length of the fin portion 15 of the radiator 11 is the same. The length of the main body case 1 in the front-rear direction is longer than the fin portion 17 of the heat absorber 13, and the fin portion 17 of the heat absorber 13 is longer than the fin portion 15 of the radiator 11.

  That is, the length of the main body case 1 in the front-rear direction is such that the fin portion 17 of the heat absorber 13 is longer than the fin portion 15 of the heat radiator 11, so that the condensed water generated in the fin portion 17 of the heat absorber 13 is dew condensation in the horizontal direction. By connecting the water droplets, the water droplets are likely to be large, so that they can be quickly collected in the drain water supply means 8, and as a result, the condensed water can be quickly supplied to the fin portion 15 of the radiator 11. Further, since the fin portion 15 of the radiator 11 is longer than the fin portion 17 of the heat absorber 13 in the vertical direction, the dew condensation water that has flowed into the radiator 11 from the drain water supply means 8 15, the distance that flows down along the fins 15 increases and spreads over a wide area of the fins 15 while flowing down along the fins 15 of the radiator 11. As a result, the fins 15 of the radiator 11 are efficiently cooled by the condensed water. can do.

  The air blowing means 18 faces the heat absorber 13 and is located near one side surface of the main body case 1, and the air blowing means 19 faces the heat radiator 11 and is located near the other side surface of the main body case 1. It is what. Specifically, the air blowing means 18 is formed of a scroll-shaped casing portion 46, an electric motor 42 installed in the casing portion 46, and a blade portion 43 that is rotated by the electric motor 42. A discharge port 44 is provided on the upper surface of the casing portion 46, and a suction port 45 is provided on a side surface facing the heat absorber 13. Similarly, the air blowing means 19 is formed of a scroll-shaped casing portion 46, an electric motor 47 installed in the casing portion 46, and a blade portion 48 rotated by the electric motor 47. A discharge port 49 is provided on the upper surface of the casing portion 46, and a suction port 50 is provided on the side surface facing the heat absorber 13. For example, the suction port 45 of the casing part 46 that is the air blowing means 18 faces the heat absorber 13, is located closer to the right side surface as viewed from the front surface of the main body case 1, and the air inlet of the casing part 46 that is the air blowing means 19. Reference numeral 50 denotes a configuration that faces the radiator 11 and is located closer to the left side surface when viewed from the front surface of the main body case 1. That is, the suction port 45 of the blower means 18 and the blower means 19 suction port 50 are respectively positioned closer to different side surfaces of the main body case 1.

  As a result, the heat absorber 13 has a larger air volume on the suction port 45 side of the air blowing means 18 in the left-right direction in the main body case 1 than an air volume on the suction port 50 side of the air blowing means 19 in the left-right direction in the main body case 1. In the heat absorber 13, the amount of condensation on the suction port 45 side of the air blowing means 18 in the left and right direction in the main body case 1 is larger than the amount of condensation on the suction port 50 side of the air blowing means 19 in the left and right direction in the main body case 1. Here, the condensed water condensed on the suction port 45 side of the air blowing means 18 in the left-right direction in the main body case 1 of the heat absorber 13 flows down to the suction port 45 side of the air blowing means 18 in the left-right direction in the main body case 1 of the radiator 11. That is, the dew condensation condensed on the suction port 50 side of the blower 19 in the left-right direction in the main body case 1 of the heat absorber 13 flows down to the suction port 50 side of the blower 19 in the left-right direction in the main body case 1 of the radiator 11. It will be.

  That is, the radiator 11 has a larger air volume on the suction port 50 side of the blower means 19 in the left-right direction in the main body case 1 than an air volume on the suction port 45 side of the blower means 18 in the left-right direction in the main body case 1. The cooling by the ventilation of the body 19 cools the suction port 50 side of the air blowing means 19 in the left-right direction in the main body case 1, but the cooling by the condensed water from the heat absorber 13 The suction port 45 side is further cooled. That is, the radiator 11 is cooled by more condensed water from the heat absorber 13 on the suction port 45 side of the air blowing means 18 in the left-right direction in the main body case 1 where the air volume by the air blowing means 19 is small. In the main body case 1 where the air volume is large, the suction port 50 side of the air blowing means 19 in the left-right direction is cooled by a small amount of condensed water from the heat absorber 13, and as a result, the entire radiator 11 is blown by air and condensed water. It can be cooled efficiently.

  Further, the air blowing means 19 is configured to be located at the lower part facing the radiator 11. That is, since the refrigerant flowing from the compressor 10 flows from the lower part to the upper part of the radiator 11, the amount of air blown by the blowing means 19 to the part where the temperature of the radiator 11 is high is increased, and the heat is radiated more efficiently. The vessel 11 can be cooled.

  Further, the humidifying means includes a water storage case 22 containing a certain amount of water, a disc-shaped humidifying filter 23 in which a part of the peripheral edge is immersed in the water of the water storage case 22, and a water storage case in the humidifying filter 23.

Specifically, the water supply case part 27 pumps up the water in the water storage case 22 at the lowest point, and supplies the water in the water supply case part 27 to the humidification filter 23 at the substantially highest point. Here, the portion of the humidifying filter 23 supplied with water at the uppermost point rotates from the air blowing means 18 toward the air blowing means 19 and faces the suction port 50 of the air blowing means 19. That is, the humidifying filter 23 portion that is supplied with water at the highest point and contains the most water faces the suction port 50 of the blowing means 19 immediately after being supplied with water, and as a result, the humidifying filter 23 portion that contains the most water. In addition, the amount of air blown by the blowing means 19 is increased, and the humidification ability can be improved.

  Moreover, as shown in FIG. 7, the communication means 9 which connects the main body case 1 and the outdoors is a flexible hollow pipe 51. Specifically, the communicating means 9 is a cylindrical flexible pipe 51 that is provided in the exhaust port 5 and has a flexible hollow shape that communicates the main body case 1 with the outside. One end of the pipe 51 is connected to the exhaust port 5 and the other end is taken out through a hole provided in the indoor wall, for example, a hole for air conditioning piping. Thus, when communicating the exhaust port 5 of the main body case 1 and the outdoors, since it is the flexible pipe 51, the piping work can be easily performed.

  The communication means 9 is provided with a heat insulating portion on the outer peripheral portion. Specifically, a heat insulating material 52 that is a heat insulating portion is wound around an outer peripheral portion of a pipe 51 that is a communication means 9. Thereby, dew condensation in the pipe 51 can be suppressed.

  Further, the air purifying means 7 is provided between the air inlet 2 and the radiator 11 and the heat absorber 13. As a result, indoor air is blown from the intake port to the radiator 11 and the heat absorber 13 via the air cleaning means 7, so that air purification can be performed while humidifying and dehumidifying.

  As described above, the present invention includes an air inlet, a first, second, and third air outlet, a main body case installed indoors, and a heat pump provided in the main body case. Is formed by a compressor and a radiator, an expansion means, and a heat sink sequentially provided downstream of the compressor, and the air exhausted into the main body case from the air inlet through the heat absorber A first air blowing means for blowing air to the opening, and a second air for blowing the air sucked into the main body case from the intake opening to the second exhaust opening or the third exhaust opening through the radiator. The first and second exhaust ports communicate with the main body case and the room, and the third exhaust port includes communication means for communicating the main body case and the outside. Humidification means is provided between the air inlet and the radiator, Air path switching means for switching the air path from the air inlet into the main body case to the second exhaust port or the third exhaust port via the radiator is generated in the heat absorber. Since the drain water supply means for flowing the condensed water to the radiator is provided, an increase in the room temperature can be reduced and the dehumidification efficiency can be improved.

  That is, in the dehumidifying operation, first, the refrigerant is brought into a high-temperature and high-pressure gaseous state by the compressor, the refrigerant flows to the radiator, and by cooling the radiator, the refrigerant is deprived of heat and then liquefied. The refrigerant liquefied by the radiator is brought into a gas-liquid two-phase state by lowering the pressure by the expansion means. Finally, the refrigerant in the gas-liquid two-phase state is passed through the heat absorber, and the room air is condensed on the heat absorber. By dehydrating, it is dehumidified. Here, when the refrigerant is cooled by the radiator, air is applied to the radiator and the radiator is cooled by the condensed water generated by the heat absorber.

  Thereby, the improvement of dehumidification efficiency can be aimed at. Furthermore, since the air that has cooled the radiator is exhausted from the third exhaust port to the outside through the communication means, an increase in the room temperature can be reduced.

  As a result, it is possible to reduce the rise in the room temperature and improve the dehumidification efficiency.

  Therefore, utilization as an air conditioner for home use or office use is expected.
