In the outdoor unit 50, the vapor refrigerant evaporated in the evaporator 31a of the indoor unit 30 is sucked into the compressor 51, compressed, sent to the condenser 52, and cooled by the condenser 52 to be a liquid refrigerant. In the indoor unit 30, the high-pressure liquid refrigerant sent from the condenser 52 is sent out to the evaporator 31 a through the expansion valve 39. The liquid refrigerant evaporates in the low-pressure evaporator 31a, and the surroundings are cooled by the heat exchanger 31. Air is sucked in from outside through the heat exchanger 31 by the blower 32 and discharged to the outside, thereby cooling the outside. FIG. 4 is a schematic side view of a conventional air conditioner indoor unit. In the indoor unit 40,
A blower 42 sucks air from the room through a heat exchanger 41 that performs heat exchange with an evaporator of a refrigeration cycle, cools the room, and sends out the cooled air through a blower outlet 44 to cool the room. When the temperature of the heat exchanger 41 is equal to or lower than the dew point temperature of the air B to be sucked in, dew forms on the heat exchanger 41.
Therefore, there is a problem that the thermal resistance between the heat exchanger and the air increases, and the performance index (COP) of the refrigeration cycle decreases. Further, it is necessary for the dew receiving tray 43 to receive all the water condensed on the heat exchanger 41. If the heat exchanger 41 is large, the equipment for drain becomes large.

The blower 22 sucks in air from the room through the dehumidifying unit 21 to dehumidify the air, and also sucks in air from the room through the opening 26 as it is. When the mixed air of the dehumidified air and the air sucked as it is cooled in the cooling unit 24, the temperature is set to a wet bulb temperature at which no dew condensation occurs. As a result, the dew condensation portion becomes only the dehumidifying portion 21 which is a part of the cooling portion, and the dew condensation does not occur in the cooling portion 24. Therefore, the thermal resistance between the air and the cooling portion 24 does not increase due to the dew condensation. The coefficient (COP) is improved.

However, since there is no condensation in the cooling units 14 (FIG. 1) and 24 (FIG. 2) according to the present invention, the planes of the fins constituting the heat exchangers serving as the cooling units 14 and 24 need to be arranged in the horizontal direction. it can. This allows the cooling units 14 and 24 to also have the function of a louver for rectifying the air to be discharged. Further, the fins constituting the heat exchangers serving as the cooling units 14 and 24 have a structure in which the fin spacing is increased toward the air discharge side so that the cooled air is uniformly discharged into the room. Further, the fins constituting the heat exchangers serving as the cooling units 14 and 24 have a structure in which the fin interval is narrowed toward the lower side of the heat exchanger, so that the fins are cooled and emit a large amount of heavy air upward. In addition, the room temperature is made uniform.
