REFRIGERATION CYCLE DEVICE

WIPO Patent Application WO/2022/038950

A1

A refrigeration cycle device provided with refrigerant circuit switching units (14a-14c, 161a-161c, 22) for switching refrigerant circuits. The refrigerant circuit switching units (14a-14c, 161a-161c, 22) switch between: a first circuit for causing a refrigerant that has been made to release heat in an outdoor heat exchanger (18) to flow into a liquid storage part (15), causing the refrigerant that has flowed out from the liquid storage part (15) to be decompressed in a second decompression unit (16b), and causing the refrigerant that has evaporated in evaporators (19, 20) to be drawn into a compressor (11); and a second circuit for causing the refrigerant that has been made to release heat in a heat dissipation unit (12) to flow into the liquid storage part (15), causing the refrigerant that flowed out from the liquid storage part (15) to to be decompressed in a first decompression unit (16a), and causing the refrigerant that evaporated in the outdoor heat exchanger (18) to be drawn into the compressor (11). When a switch is made from the first circuit to the second circuit, the compressor (11) is stopped, and an outdoor unit inlet-side opening/closing part (161a) for opening/closing the inlet side of the outdoor heat exchanger (18) is closed.
