WIPO Patent Application WO/2019/065855
Kind Code:
A1
Abstract:
A first flow adjustment valve (14) provided on the outflow side of a heat source-side heat exchanger (12) and a second flow adjustment valve (23) provided on the outflow side of a first use-side heat exchanger (22) are connected in a refrigeration circuit (2). A control unit (100) is provided which, during an operation in which the heat source-side heat exchanger (12) and the first use-side heat exchanger (22) act as a condenser and a second use-side heat exchanger (32, 42) acts as an evaporator, adjusts the opening degree of the flow adjustment valves (14, 23) on the basis of an index that indicates the amount of liquid refrigerant accumulated in the heat source-side heat exchanger (12) and the first use-side heat exchanger (22).
