Abstract
The invention relates to a ventilation, heating and/or air conditioning equipment for the passenger compartment of a motor vehicle provided with a main thermodynamic loop comprising at least, according to the direction of flow of a refrigerant fluid: a compressor (14), a condenser (16), an expansion device (20), and a main air-cooling evaporator (22). According to the invention, the equipment furthermore comprises a secondary fluid loop for the flow of a heat conductor fluid coupled with the main thermodynamic loop in order to cool the heat conductor fluid when this is desirable.
Claims15
