17 Claims

1. A method for regulation of the temperature of a battery of an electric or hybrid motor vehicle by means of a system comprising a vapor compression circuit in which a first heat-transfer composition comprising 2,3,3,3-tetrafluoropropene circulates and a secondary circuit in which a second heat-transfer composition comprising 1-chloro-3,3,3-trifluoropropene having a Z form to E form ratio of less than or equal to 9 circulates, the method comprising:

an exchange of heat between the battery and the second heat-transfer composition;

an exchange of heat between the second heat-transfer composition and the first heat-transfer composition.
