PROBLEM TO BE SOLVED: To provide a method for heating and/or air conditioning of a passenger compartment of an automobile using a reversible cooling loop, where the method is particularly useful when outdoor temperature is -15°C or less and can be used for hybrid automobiles designed for operation alternatively using a thermal engine and an electric motor.SOLUTION: The invention relates to a method for the heating and/or air conditioning of a passenger compartment of an automobile using a reversible cooling loop in whose interior a coolant flows. The interior has a first heat exchanger 13, an expansion valve 14, a second heat exchanger 15, a compressor 11, and means 12 for reversing the direction of the flow of the coolant. The coolant comprises 2,3,3,3-tetrafluoropropene. |
