초록

A composition includes between 11 and 13 wt. % of difluoromethane; between 58 and 62 wt. % of pentafluoroethane; between 18 and 29 wt. % of tetrafluoropropene; and between 0 and 7 wt. % of propane. The tetrafluoropropene can be 1,3,3,3-tetrafluoropropene or 2,3,3,3-tetrafluoropropene. The composition can be used as a heat transfer fluid in a vapor compression circuit.

청구항

1. A composition comprising: from 11 to 13% by weight of difluoromethane;from 58 to 62% by weight of pentafluoroethane;from 18 to 29% by weight of 2,3,3,3-tetrafluoropropene; andfrom 0 to 7% by weight of propane. 2. A process for heating or cooling a fluid or a body by means of a vapor compression circuit containing a heat transfer fluid, said process successively comprising the evaporation of the heat transfer fluid, the compression of the heat transfer fluid, the condensation of the heat fluid and the expansion of the heat transfer fluid, wherein the h...
