PROBLEM TO BE SOLVED: To provide a heat pump device and an organic Rankine cycle device capable of maintaining a stable heat cycle even if HFO or HCFO is used as a refrigerant.SOLUTION: A refrigerant circulation device 1 is a refrigerant circulation device using a refrigerant. The refrigerant contains hydrofluoroolefin or hydrochlorofluoro-olefin including carbon-carbon double bonds in a molecular structure, and a reaction inhibition unit 6 inhibiting an isomerization reaction of the refrigerant is provided in a refrigerant circulation circuit. The reaction inhibition unit 6 includes a reaction inhibitor mainly containing at least one type of a material selected from the group consisting of copper, iron, aluminum, nickel, titanium, metal silicon, silicon steel, tin, magnesium, zinc, and zeolite. |
