refrigerant composition comprising difluoromethane (HFC32), pentafluoroethane (HFC125) and 2,3,3,3-tetrafluoropropene (HFO1234yf)

摘要

Use of a refrigerant composition in conditioners domestic / industrial air, wherein cooling comprises lacomposición difluoromethane (HFC32), pentafluoroethane (HFC125) and 2,3,3,3-tetrafluoropropene (HFO-1234yf), being the ratio of HFC32 / HFC125 / HFO1234yf in a intervalodelimitado by points (0/21/79 mass%), (16.6 / 25.3 / 58.1 mass%) and (0 / 28.4 / 71.6 mass%) in undiagrama a ternary refrigerant composition containing HFC32, HFC125 and HFO1234yf and essentially comprising HFC32 lacomposición.
