Abstract

A refrigeration cycle device according to the present disclosure is capable of causing two load-side heat exchangers to independently function as radiators or evaporators. A compressor, a flow-passage switching device, and a heat-source-side heat exchanger, from among the components of the refrigeration cycle device, are heat-source-side components. A throttle device and load-side heat exchangers, from among the components of the refrigeration cycle device, are load-side components. If the heat-source-side components and the load-side components are defined in this manner, when the refrigeration cycle device according to the present disclosure causes both two load-side heat exchangers to function as radiators, a coolant flows through all of a plurality of coolant pipes coupling the heat-source-side components to the load-side components.
