Refrigerants containing (E)-1,1,1,4,4,4-hexafluorobut-2-ene

摘要

A composition including (E)-1,1,1,4,4,4-hexafluorobat-2-ene as a mixture with at least one hydrocarbon, hydrofluorocarbon or fluoroolefin compound having a boiling point less than or equal to −12° C., and also to the use of this composition as a heat transfer fluid. A process for reducing the environmental impact of heat-transfer equipment including a vapor compression circuit containing an initial heat-transfer fluid, said process comprising a step replacing the initial heat-transfer fluid in the vapor compression circuit with a final heat-transfer fluid, the final heat-transfer fluid having a GWP which is lower than the initial heat-transfer fluid, wherein the final heat-transfer fluid is the above composition.

1. A composition comprising (E)-1,1,1,4,4,4-hexafluorobut-2-ene and at least one compound having a boiling point less than or equal to −12° C. at a pressure of 101.325 KPa selected from the group consisting of an ether, a hydrofluoroether and a fluoroolefin, wherein the difference between the liquid saturation pressure and the vapor saturation pressure of the composition at a temperature of −5° C. is less than or equal to 10% of the liquid saturation pressure.
