This binary refrigeration cycle device has: a low-temperature-side refrigeration cycle provided with a low-temperature-side compressor and a heat-source-side heat exchanger that absorbs heat from an external heat source; a high-temperature-side refrigeration cycle provided with a high-temperature-side compressor and a use-side heat exchanger that supplies heat to the use side; an intermediate heat exchanger for exchanging heat between the refrigerants of the low-temperature-side refrigeration cycle and the high-temperature-side refrigeration cycle; a casing that is loaded with at least the use-side heat exchanger; use-side piping that is loaded in the casing, is connected to the use-side heat exchanger, causes heat exchange and supply to the use side of a use-side fluid flowing through and the refrigerant of the high-temperature-side refrigeration cycle; a bypass pathway that is connected in parallel to the use-side piping and the use-side heat exchanger, and that sends the use-side fluid at the use-side heat exchanger exit side of the use-side piping to the use-side heat exchanger entrance side; and a fluid control means that controls the flow of the use-side fluid flowing within the bypass pathway. |
