Abstract (en)
[origin: WO2011141655A2] The invention relates to a ternary composition comprising: - from 5 to 50% of difluoromethane; - from 2 to 20% of pentafluoroethane; and - from 30 to 90% of tetrafluoropropene. The tetrafluoropropene may be 1,3,3,3-tetrafluoropropene or 2,3,3,3-tetrafluoropropene. This composition can be used as a heat-transfer fluid in a vapour compression circuit.
