Abstract:
The present disclosure provides a gas heat pump air conditioner that can prevent refrigeration oil from staying in a heat exchanger when the heat exchanger is used as an evaporator. This air conditioner is configured by a compressor 101, an outdoor heat exchanger 106, a flow rate adjustment valve 112, and an indoor heat exchanger 201 being sequentially connected in a ring by refrigerant piping, circulates a refrigerant through the refrigerant piping, exchanges heat with the air in a predetermined space with the indoor heat exchanger 201, and controls the temperature of the predetermined space. The outdoor heat exchanger 106 is equipped with a first region 106a and a second region 106b in which the refrigerants circulate parallel to each other, and an open-close valve 113 that is installed at the refrigerant inlet of the first region 106a on the flow rate adjustment valve 112 side.
