Abstract
To provide a composition for a hat cycle system which comprises a working fluid containing 1,1,2-trifluoroethylene, having cycle performance sufficient as an alternative to R410A while suppressing influence over global warming, and a heat cycle system employing the composition. A composition for a heat cycle system, which comprises a working fluid for heat cycle containing 1,1,2-trifluoroethylene, CF3I and at least one compound selected from a hydrofluorocarbon, a hydrofluoroolefin other than 1,1,2-trifluoroethylene and a hydrocarbon, and having a temperature glide of at most 7° C., and a heat cycle system employing the composition for a heat cycle system.
Claims12
A composition for a heat cycle system, comprising:
- a working fluid for heat cycle containing 1,1,2-trifluoroethylene, CF3I and 2,3,3,3-tetrafluoropropene,
- wherein the working fluid has and having a temperature glide of at most 7° C.,
- a content of the 2,3,3,3-tetrafluoropropene is 50 mass % or more relative to a total content of the 1,1,2-trifluoroethylene, the CF3I, and the 2,3,3,3-tetrafluoropropene,
- a content of the 1,1,2-trifluoroethylene is 20 mass % or more relative to a total content of the working fluid, and
- a total content of the 1,1,2-trifluoroethylene and the CF3I is 50 mass % or less relative to the total content of the working fluid.
