Title:
REFRIGERATION CYCLE DEVICE
Document Type and Number:
WIPO Patent Application WO/2020/213537
Kind Code:
A1
Abstract:
This refrigeration cycle device (10) is provided with refrigeration circuit switching units (14a-14c). The refrigeration circuit switching units (14a-14c) switch: a first circuit that allows a refrigerant flowing out of a heat dissipating unit (12, 62) to flow into a liquid reservoir unit (15), allows the refrigerant flowing out of the liquid reservoir unit (15) to flow into a first depressurizing unit (16a), and further allows the refrigerant depressurized in the first depressurizing unit (16a) to flow into an outdoor heat exchanger (18); and a second circuit that allows the refrigerant flowing out of the outdoor heat exchanger (18) to flow into the liquid reservoir unit (15), allows the refrigerant flowing out of the liquid reservoir unit (15) to flow into second depressurizing units (16b-16d), and further allows the refrigerant depressurized in the second depressurizing units (16b-16d) to flow into evaporating units (19, 19a, 30a, 72).
