AIR CONDITIONER

摘要

In dehumidification operation, too large an air volume of an indoor unit leads to too small an extent of the evaporation region of an indoor heat exchanger to dehumidify the air. An air conditioner of the present invention is capable of performing: cooling operation in which the entirety of the indoor heat exchanger functions as the evaporation region; and dehumidification operation in which a portion of the indoor heat exchanger close to a liquid inlet functions as the evaporation region. The air conditioner includes an indoor fan opposed to the indoor heat exchanger. In the dehumidification operation, the compressor and the expansion valve are controlled so that the extent of the evaporation region varies depending on a load. The maximum number of revolutions of the indoor fan in the dehumidification operation is smaller than the maximum number of revolutions of the indoor fan in the cooling operation.
