Abstract: To provide a working medium for heat cycle which has less influence over the ozone layer, which has less influence over global warming and which provides a heat cycle system excellent in the cycle performance (the efficiency and the capacity), and a heat cycle system excellent in the cycle performance (the efficiency and the capacity). A working medium for heat cycle comprising 1,2-difluoroethylene is employed for a heat cycle system (such as a Rankine cycle system, a heat pump cycle system, a refrigerating cycle system 10 or a heat transport system).

Abstract: There are provided an air-conditioner working fluid for electric vehicle providing sufficient cycle performance in practical use in an electric vehicle, in particular, sufficient cycle performance also in the heating time, while suppressing influence on global warming, and usable without greatly changing an air-conditioner device for a conventional working fluid, for example, HFC-134a or HFO-1234yf, and an air-conditioner working fluid composition for electric vehicle containing the same. The air-conditioner working fluid for electric vehicle contains trifluoroethylene, difluoromethane and 1,3,3,3-tetrafluoropropene, wherein a percentage of a total amount of trifluoroethylene, difluoromethane and 1,3,3,3-tetrafluoropropene with respect to a total amount of the working fluid is more than 90 mass % and 100 mass % or less.

Abstract: A refrigeration cycle apparatus includes a compressor, a condenser, a pressure reducing mechanism and an evaporator and use a working fluid containing a hydrofluoroolefin (HFO). The compressor, condenser, pressure reducing mechanism and evaporator are connected with a pipeline to form a refrigeration cycle. A deoxidizing portion where the working fluid is brought into contact with a desiccant or a deoxidizer is provided at any place within the refrigeration cycle.
