Abstract (en)
[origin: WO2019197783A1] The invention relates to a method for cooling and/or heating a body or a fluid in a motor vehicle using a system comprising a steam compression circuit in which flows a first heat transfer composition and a secondary circuit in which flows a second heat transfer composition. The invention also relates to an installation for cooling and/or heating a body or a fluid in a motor vehicle, and to a use for cooling and/or heating a body or a fluid in a motor vehicle, to a heat transfer composition comprising one or more heat transfer compounds having a boiling point between 0 and 40°C, chosen from among the hydrochlorofluoroolefins, the hydrofluoroolefins and combinations thereof.
