WIPO Patent Application WO/2019/146099

A1

An air conditioning device according to the present invention has a compressor, a condenser, an expansion valve, an evaporator, a receiver for storing excess refrigerant and connected between the condenser and the expansion valve, and a pump connected between the receiver and the expansion valve, and executes a refrigeration cycle and a pump cycle. The receiver is equipped with a first inlet, which is an inlet enabling refrigerant to flow into the receiver. The condenser has a first outlet, which is an outlet enabling refrigerant to flow out from the condenser, said first outlet being at a lower position than the first inlet. A refrigerant circulation circuit is equipped with a bypass pipe a first end of which, that is, a refrigerant inflow-side end of which is connected between the first outlet and the first inlet at a position lower than the first inlet, and a second end of which, that is, a refrigerant outflow-side end of which is connected between the receiver and the pump.
