Title:
AIR CONDITIONER
Document Type and Number:
WIPO Patent Application WO/2013/157406
Kind Code:
A1
Abstract:
A problem exists in which dehumidification cannot be carried out when the load decreases. The air conditioner of the present invention comprises an indoor heat exchanger having an auxiliary heat exchanger (20) and a main heat exchanger (21) that is arranged on the downstream side of the auxiliary heat exchanger (20). During operation in a predetermined dehumidifying operation mode, all of the liquid refrigerant supplied to the auxiliary heat exchanger (20) evaporates partway through the auxiliary heat exchanger (20). As a result, only a portion of the upstream side of the auxiliary heat exchanger (20) is an evaporation region, and the area on the downstream side of the evaporation region for the auxiliary heat exchanger (20) is a superheating region. In addition, during the predetermined dehumidifying operation, a compressor and an expansion valve are controlled so that the area of the evaporation region of the auxiliary heat exchanger (20) changes in accordance with the load.
