A working fluid for a heat cycle, comprising:
- trifluoroethylene;
- a first component comprising propane;
- and
- a second component selected from the group consisting of hydrofluoroolefins where trifluoroethylene is excluded,
- wherein
- the hydrofluoroolefins have a global warming potential in the Intergovernmental Panel on Climate Change Fourth Assessment Report of 2000 or less,
- a ratio of a total amount of the trifluoroethylene, the first component and the second component with respect to an entire amount of the working fluid for the heat cycle is in a range of over 90 mass % to 100 mass %,
- a ratio of an amount of the trifluoroethylene with respect to the total amount of the trifluoroethylene, the first component and the second component is in a range of 10 mass % to 90 mass %,
- a ratio of an amount of the propane with respect to the total amount of the trifluoroethylene, the first component and the second component is in a range of 10 mass % to 50 mass %, and
- a ratio of an amount of the second component with respect to the total amount of the trifluoroethylene, the first component and the second component is in a range of 1 mass % to 70 mass %.
