    Abstract: A working fluid for heat cycle, a composition for a heat cycle system containing the working fluid, and a heat cycle system employing the composition are provided. The working fluid contains trifluoroethylene, 2,3,3,3-tetrafluoropropene, and difluoromethane. A proportion of the total amount of trifluoroethylene, 2,3,3,3-tetrafluoropropene, and difluoromethane based on the entire amount of the working fluid is higher than 90 mass % and at most 100 mass %. Based on the total amount of trifluoroethylene, 2,3,3,3-tetrafluoropropene, and difluoromethane, the proportion of trifluoroethylene is at least 10 mass % and less than 70 mass %, the proportion of 2,3,3,3-tetrafluoropropene is at most 50 mass %, and the proportion of difluoromethane is higher than 30 mass % and at most 75 mass %. The working fluid can replace R410A and has a low global warming potential and high durability.

    Abstract: There are provided a heat cycle system that uses a system for heat cycle designed to use 1,1,1,3,3-pentafluoropropane (HFC-245fa) as a working fluid as it is and is thereby excellent in economic efficiency, and is equal to or higher in cycle performance and lower in environmental burden than in the case of using HFC-245fa, and a heat cycle method using the heat cycle system. The heat cycle system includes a working fluid and a system for heat cycle, the system for heat cycle is suitable for HFC-245fa being used as a working fluid, and the working fluid contains 1-chloro-2,3,3,3-tetrafluoropropene, and the heat cycle method uses the heat cycle system.
