Title:
REFRIGERATION CYCLE DEVICE
Document Type and Number:
WIPO Patent Application WO/2020/071300
Kind Code:
A1
Abstract:
A refrigeration cycle device that has a main refrigerant circuit (20) and a sub refrigerant circuit (80) and cools or heats a main refrigerant flowing between a main heat source-side heat exchanger (25) and main usage-side heat exchangers (72a, 72b), by causing a sub usage-side heat exchanger (85) to function as a sub refrigerant evaporator or radiator. A first main expansion mechanism (27) and second main expansion mechanisms (71a, 71b, 44), that decompress the main refrigerant, are provided on the upstream and downstream sides of the sub usage-side heat exchanger (85) in the main refrigerant circuit (20).
