ートポンプ式空調機。 A heat pump type that can be heated and cooled using a compressor, an air conditioning/heating switching valve, an indoor heat exchanger, an outdoor heat exchanger, a pressure reducing device, and a liquid injection circuit that connects the compressor to piping that connects the indoor heat exchanger and pressure reducing device. In the heat pump type air conditioner which constitutes a refrigerant circuit and performs defrosting operation by sending high temperature refrigerant discharged from the compressor to the outdoor heat exchanger when frost forms on the outdoor heat exchanger during heating, A heat pump type air conditioner characterized in that an on-off valve is provided in a liquid injection circuit, the on-off valve is closed during defrosting operation, and the defrosting operation is performed after the discharge temperature rises.
