Abstract:
An object of the present invention is to provide an air-conditioning apparatus that can control a decrease in efficiency of a refrigeration cycle. The air-conditioning apparatus includes a suction pipe having one end connected to a suction side of a compressor and an other end connected to an evaporator, a receiver connected to a refrigerant pipe connecting the evaporator and a condenser to each other, a first bypass pipe having one end connected to the receiver and an other end connected to the suction pipe and configured to supply refrigerant from the receiver to the suction pipe, a flow control valve provided to the first bypass pipe, a heat recovery portion disposed downstream of a portion of the suction pipe connected to the first bypass pipe and configured to exchange heat between refrigerant flowing into the suction pipe from the evaporator and the first bypass pipe and refrigerant in the receiver, and a control device configured to control an opening degree of the flow control valve based on a degree of superheat of refrigerant in the heat recovery portion.
