초록

A ternary composition including: 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 vapor compression circuit. A process for heating or cooling a fluid or a body using a vapor compression circuit containing a heat transfer fluid, said process successively including evaporation of the heat transfer fluid, compression of the heat transfer fluid, condensa...
