Embodiment Construction

[0055] In the following description, the invention is now described in a more detailed and non-limiting manner.

[0056] The invention relates to a heat transfer method for cooling and / or heating objects or fluids in a motor vehicle, which method is implemented by means of a heat transfer device. The apparatus comprises first and second heat transfer compositions, each heat transfer composition comprising a heat transfer fluid comprising one or more heat transfer compounds.

[0057] In the application under consideration, the term "heat transfer compound" is intended to mean a compound capable of absorbing heat by evaporation and releasing heat by condensation.

[0058] In the context of the present invention, "HFO-1234yf" means 2,3,3,3-tetrafluoropropene, "HCFO-1233zd" means 1-chloro-3,3,3-trifluoropropene, "HCFO- 1224yd" refers to 1-chloro-2,3,3,3-tetrafluoropropene, and "HFO-1336mzz" refers to 1,1,1,4,4,4-hexafluorobut-2-ene.

[0059] The motor vehicle may be a combustion...

Abstract

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 compositionand 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 usefor 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 DEG C, chosen from among the hydrochlorofluoroolefins, the hydrofluoroolefins and combinations thereof.

Description

technical field [0001] The invention relates to a method for cooling and / or heating objects or fluids in a motor vehicle, and a device suitable for carrying out the method. The present invention also relates to the use of hydrochlorofluoroolefins and hydrofluoroolefins having a boiling point of 0-40° C. for this purpose. Background technique [0002] In motor vehicles, a heat engine comprises a circuit for the circulation of a heat exchange fluid, which is used to cool the engine and to heat the passenger compartment. To this end, said circuit notably comprises a pump and a unit heater (heater, unit heater), in which an air flow is circulated, which takes up the heat stored by the heat exchange fluid to heat the passenger compartment. [0003] Furthermore, an air-conditioning (air-conditioning) system intended to cool the passenger compartment of a motor vehicle includes an evaporator, a compressor, a condenser, an expansion valve, and a fluid (commonly called as refriger...
