Abstract (en)
There is provided a refrigerant circuit system (1) capable of being effectively operated even if there is a change in a utilization-side inlet temperature of a heat pump or the like. The refrigerant circuit system (1) includes a compressor (10), a utilization-side heat exchanger (11), a receiver (14), a first expansion valve (12) configured to depressurize a refrigerant introduced from the utilization-side heat exchanger (11), a receiver, a second expansion valve (15) configured to depressurize the refrigerant flowing out from the receiver, a heat source-side heat exchanger (17), a first bypass circuit (13) configured to bypass the flow of the refrigerant passing through the first expansion valve (12), a second bypass circuit (16) configured to bypass the flow of the refrigerant passing through the second expansion valve (15), and a control device (100) configured to control opening and closing of the first bypass circuit (13) and opening and closing of the second bypass circuit (16).
