和機。 A refrigeration cycle is constructed by connecting the compressor, four-way valve, outdoor heat exchanger, electronic expansion valve whose opening is controlled during cooling and heating and fully closed during defrost, and the indoor heat exchanger in this order. In an air source heat pump type air conditioner in which the four-way valve is switched to guide discharge gas from the compressor to an outdoor heat exchanger, a refrigerant circuit between the outdoor heat exchanger and the electronic expansion valve is provided. Between the four-way valve and the refrigerant circuit between the indoor heat exchanger, a throttle, an on-off valve that opens during defrosting, a check valve that only allows refrigerant to flow from the outdoor heat exchanger side, and a heat storage material are provided. A bypass circuit is provided in which heat storage units having a heat exchanger are sequentially connected, and in parallel with the heat storage unit, a part of the high-temperature refrigerant gas flowing in the refrigerant circuit between the four-way valve and the indoor heat exchanger is reverse-blocked during heating operation. An air heat source heat pump type air conditioner characterized by having a circuit for natural circulation via a valve.
