Title:
REFRIGERATION CYCLE DEVICE
Document Type and Number:
WIPO Patent Application WO/2021/140625
Kind Code:
A1
Abstract:
A refrigeration cycle device (100), wherein a refrigerant circulates in the order of a compressor (1), a first heat exchanger (2), a decompression device (3), and a second heat exchanger (4). The refrigeration cycle device (100) comprises a refrigerant container (5), a first switching unit (6), a second switching unit (7), and a control device (10). If a first condition, which indicates that the amount of liquid refrigerant stored in the refrigerant container (5) is excessive, is satisfied, the control device (10) controls the first switching unit (6) to lead the refrigerant from the compressor (1) to the first heat exchanger (2) through the refrigerant container (5), and controls the second switching unit (7) to lead the refrigerant from the second heat exchanger (4) to the compressor without going through the refrigerant container (5). If the first condition is not satisfied, the control device (10) controls the first switching unit (6) to lead the refrigerant from the compressor (1) to the first heat exchanger (2) without going through the refrigerant container (5), and controls the second switching unit (7) to lead the refrigerant from the refrigerant container (5) to the compressor (1).
