Zusammenfassung:	The refrigerant device (10) includes a refrigerant circuit (20) performing a refrigeration cycle in which one of the heat-source-side heat exchanger (23) and the utilization-side heat exchanger (28) serves as a radiator, while the other serves as an evaporator. The refrigerant circuit (20) is filled with a refrigerant including hydrocarbon fluoride having the property of causing disproportional reaction. The refrigerant circuit (20) includes an ejector (25) provided with a depressurization channel (25a), a suction channel (25b) and an ejection channel (25c), a gas-liquid separator (26) into which a refrigerant ejected from the ejection channel (25c) flows, an expansion mechanism (27) depressurizing a liquid refrigerant flowing from the gas-liquid separator (26) into the evaporator, and a suction pipe (21b) guiding a gas refrigerant of the gas-liquid separator (26) into the compressor (21). As a result, it is possible to reduce the risk of disproportional reaction of the refrigerant.
