徴とするヒートポンプ式空調機。 A heat pump air conditioner consists of a compressor, an indoor heat exchanger, an outdoor heat exchanger, a pressure reducer, a four-way valve, etc. It also includes a liquid injection circuit that injects a portion of the high-pressure liquid refrigerant into the compression stroke, a compressor, and a four-way valve. For those equipped with a hot gas bypass circuit with an on-off valve interposed between the piping connecting the indoor heat exchanger and the piping connecting the pressure reducing device and the outdoor heat exchanger, an on-off valve is provided in the liquid injection circuit. During defrosting operation, the on-off valve of the hot gas bypass circuit is opened and the pressure reducing device is closed, and the on-off valve of the liquid injection circuit is controlled to be opened when the low pressure falls below a set value. Heat pump type air conditioner.
