Abstract

In order to solve the problems of ventilation and dehumidifying of an air conditioner, the air conditioner includes a refrigerant circuit formed by coupling at least a compressor (7), an indoor heat exchanger (4), a decompressor (8) and an outdoor heat exchanger (6), a humidifying/dehumidifying apparatus (10, 11, 12, 13, 14) provided separate from the refrigerant circuit, for removing moisture in the room, a moisture detection sensor (31) for detecting indoor moisture, and a control unit (34) for switching an operation mode based on the moisture detected by the moisture detection sensor (31). The humidifying/dehumidifying apparatus (10, 11, 12, 13, 14) guides the sucked indoor air to a path communicated to the room and a path communicated to the outside of the room in a ventilation mode (37, 35), and guides the sucked indoor air to the outside of the room in a dehumidifying mode.
