Abstract:
A device for cooling the engine of a motor vehicle and for air conditioning the passenger compartment of the vehicle, includinga) a heat-conveying fluid first circuit including a radiator for cooling the engine and a heat exchanger through which flows air to be directed into the passenger compartment, andb) a refrigerant fluid second circuit including a compressor, a condenser, an expansion unit and an evaporator, the condenser and the evaporator being capable of tranferring heat from a first medium in contact with the evaporator to a second medium in contact with the condenser via the refrigerant fluid to cool said flow of air, wherein said first and second media are the heat-conveying fluid flowing in the first circuit, the first circuit including a supply member capable of being selectively in communication between the heat exchanger and either the engine or the evaporator for supplying said heat exchanger with a flow of hot fluid from the engine or a flow of fluid cooled by the evaporator or a mixture of hot fluid and cold fluid, to regulate the temperature of said flow of air.
