Title
(EN) Working medium for heat cycle and heat cycle system
Abstract
(EN)

A working medium for heat cycle includes 1,1-dichloro-2,3,3,3-tetrafluoropropene, and a hydrofluorocarbon. A content of the hydrofluorocarbon is from 1 to 60 mass % in the working medium for heat cycle. The working medium for heat cycle preferably further includes a hydrocarbon. The hydrofluorocarbon is preferably at least one of difluoromethane, difluoroethane, trifluoroethane, tetrafluoroethane, pentafluoroethane, pentafluoropropane, hexafluoropropane, heptafluoropropane, pentafluorobutane or heptafluorocyclopentane. A heat apparatus includes the working medium for heat cycle.
