Title:

AIR CONDITIONER

Document Type and Number:

WIPO Patent Application WO/2015/056780

Kind Code:

A1

Abstract:

During dehumidifying operations, the amount of blowing of an indoor unit is excessively large, the range of the evaporation region of an indoor heat exchanger becomes small, and it is not possible to dehumidify. This air conditioner performs a cooling operation in which the entirety of an indoor heat exchanger is the evaporation region, and a dehumidifying operation in which the portion closer to a liquid entrance of the indoor heat exchanger is the evaporation region. The air conditioner has an indoor fan that opposes the indoor heat exchanger; during the dehumidifying operation, a compressor and an expansion valve are controlled in a manner such that the range of the evaporation region changes in accordance with the load; and the maximum rotational frequency of the indoor fan during the dehumidifying operation is less than the maximum rotational frequency of the indoor fan during the cooling operation.
