The present invention relates to a composition 2,3,3,3-tetrafluoropropene, 1,1,1,2-tetrafluoroethane and at least one compound selected from propane, propylene and ethylene, which can be used for refrigeration, air-conditioning and heating. The invention also relates to a method for heating and/or air-conditioning the passenger compartment of an automobile using a reversible cooling loop in which a refrigerant fluid including said composition flows. The method is particularly suitable for when the outdoor temperature is lower than −20° C. The method is also suitable for use in hybrid vehicles adapted for alternately operating by means of a thermal engine and an electric motor, as well as for electric vehicles.
