This refrigeration cycle device, a plurality of which are coupled to constitute a refrigeration cycle system, comprises a refrigerant circuit (10) configured by connecting, via refrigerant piping, a compressor (1), a channel switching device (6), a heat source side heat exchanger (2), an expansion device (4), and a refrigerant channel of a heat carrier heat exchanger (50) having a heat carrier channel in which a heat carrier flows and the refrigerant channel in which a refrigerant which will exchange heat with the heat carrier flows, wherein the refrigerant is circulated inside the refrigerant circuit (10). The refrigeration cycle device further comprises: a heat carrier inlet pipe (60a), both ends of which are coupling portions and an intermediate portion of which is connected to a heat carrier inflow port (5a) of the heat carrier heat exchanger (50); a heat carrier outlet pipe (60b), both ends of which are coupling portions and an intermediate portion of which is connected to a heat carrier outflow port (5b) of the heat carrier heat exchanger (50); and a set of opening and closing means (61) that is installed between the intermediate portion and at least one end of the ends of the heat carrier inlet pipe (60a) and heat carrier outlet pipe (60b). |
