<p>The invention relates to a device for heating and ventilating the passenger compartment of a motor vehicle with an engine which releases only a small amount of heat. The device includes an air inlet (14) equipped with an air impeller (20), an air outlet (38) feeding at least one outlet duct (40, 42) emerging in the passenger compartment (H), an air-heating branch (30) interposed between the air inlet and the air outlet, and heating means contained in the air-heating branch (30), these means comprising an electric radiator (48) with pure resistance, and an electric radiator (50) with a resistance with a positive temperature coefficient, these two radiators being electrically connected in series in a circuit powered by a voltage source (58). The device makes it possible to match the electrical power consumed to the heat power desired, this being under conditions of maximum safety. <IMAGE></p> |
