To provide a working medium for heat cycle which has inflammability suppressed, 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 (efficiency), and a heat cycle system whereby safety is secured and which is excellent in the cycle performance (efficiency). A working medium for heat cycle comprising 1,1-dichloro-2,3,3,3-tetrafluoropropene 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). |
