Title:
REFRIGERATION CYCLE DEVICE
Document Type and Number:
WIPO Patent Application WO/2021/111605
Kind Code:
A1
Abstract:
A refrigeration cycle device (100), wherein a refrigerant circulates. The refrigeration cycle device (100) comprises a compressor (1), a first heat exchanger (2), a second heat exchanger (6), a first receiver (31), a second receiver (32), a first valve (4), an expansion valve (5), and a bypass unit (7). The first receiver (31) and the second receiver (32) retain a liquid refrigerant. The refrigerant circulates through the compressor (1), the first heat exchanger (2), the first receiver (31), the second receiver (32), the first valve (4), the expansion valve (5), and the second heat exchanger (6) in the stated order. The bypass unit (7) guides the refrigerant from the first heat exchanger (2) to the second receiver (32) so as not to pass through the first receiver (31).
