Title:
REFRIGERATION CYCLE DEVICE
Document Type and Number:
WIPO Patent Application WO/2022/038951
Kind Code:
A1
Abstract:
Provided is a refrigeration cycle device comprising a heating unit (12, 121, 50), a first decompression unit (13), an outdoor heat-exchange unit (14), a second decompression unit (16), and an indoor evaporation unit (17). The heating unit (12, 121, 50) heats air to be blown. The first decompression unit (13) decompresses a refrigerant flowing out from the heating unit (12, 121, 50). The outdoor heat-exchange unit (14) performs heat exchange between the refrigerant flowing out from the first decompression unit (13) and outside air. The second decompression unit (16) decompresses the refrigerant flowing out from the outdoor heat-exchange unit (14). The indoor evaporation unit (17) cools the air to be blown before said air is heated at the heating unit (12, 121, 50). A first decompression control unit (40b) controls the operation of the first decompression unit (13) such that the supercooling degree (SC1) of the refrigerant flowing into the first decompression unit (13) is a target supercooling degree (SCO) or less.
