Abstract:
To provide a composition for a heat cycle system having favorable lubricating properties and comprising a working fluid for heat cycle which has a low global warming potential and which can replace R410A, and a heat cycle system employing the composition. A composition for a heat cycle system, which comprises a working fluid for heat cycle containing an unsaturated fluorinated hydrocarbon compound having a specific structure, and a refrigerant oil having a breakdown voltage of at least 25 kV, a hydroxy value of at most 0.1 mgKOH/g, and a kinematic viscosity at 40° C. of from 5 to 200 mm 2 /s and a kinematic viscosity at 100° C. of from 2 to 30 mm 2 /s, and a heat cycle system employing the composition for a heat cycle system.

Claim (Index 8):
The composition for a heat cycle system according to  claim 4 , wherein trifluoroethylene and 2,3,3,3-tetrafluoropropene are contained as the unsaturated fluorinated hydrocarbon compound, and difluoromethane is contained as the saturated fluorinated hydrocarbon compound,\n the proportion of the total amount of trifluoroethylene, 2,3,3,3-tetrafluoropropene and difluoromethane based on the entire amount of the working fluid for heat cycle is higher than 90 mass % and at most 100 mass %, and 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 higher than 0 mass % and at most 50 mass %, and the proportion of difluoromethane is higher than 30 mass % and at most 75 mass %.
