[PROBLEMS] To provide a heat cycle working medium that provides a heat cycle system that is less combustible, has less impact on the ozone layer, has less impact on global warming, and has excellent cycle performance (capacity), and safety. And providing a thermal cycle system with excellent cycle performance (capacity). A working medium for heat cycle containing 1,1,2-trifluoroethylene and difluoromethane is used in a heat cycle system (Rankine cycle system, heat pump cycle system, refrigeration cycle system 10, heat transport system, etc.). Use. [Selection] Figure 1 |
