Abstract:
1. An air conditioner comprising: a supply air passage which introduces outside air into a room; an exhaust air passage which discharges air from the room; a dehumidifier having adsorbing means capable of adsorbing moisture in air, a part of the dehumidifier being disposed in the supply air passage, a part or all of a remaining part of the dehumidifier being disposed in the exhaust air passage, the adsorbing means adsorbing moisture in supply air in the supply air passage, the adsorbing means being dried by exhaust air in the exhaust air passage; a refrigerating device provided with a refrigeration cycle including: a compressor; a heater which is disposed on a discharge side of the compressor and which is disposed so that a refrigerant compressed by the compressor radiates heat to heat exhaust air in the exhaust air passage; an expansion valve into which the refrigerant flows that has radiated heat in the heater; and an evaporator which is disposed on an outlet side of the expansion valve and which is disposed so that the refrigerant whose pressure has been lowered by the expansion valve evaporates to cool supply air in the supply air passage; and a sensible heat exchanger which allows supply air dehumidified by the rotary dehumidifier to exchange sensible heat with exhaust air before flowing into the heater, the refrigerating device having a heat exchanger between an outlet side of the heater and an inlet side of the expansion valve, the heat exchanger being disposed externally from the exhaust air passage and the supply air passage.
