Control device for a vehicle air-conditioning system

Air conditioning unit for vehicle which is compact and economical, while ensuring simplification of the combination of means for controlling the temperature of different elements of the vehicle. The unit comprises a fan which supplies two conduits placed parallel, of which one permanently heats the air by contact with a heating component, the heated air being dispatched either into the passenger space, or towards the exterior with the aid of a valve. The other conduit is opened or closed by a valve, according to whether one wishes to cool or to heat the passenger space. The heating component is thus permanently cooled, both when the passenger space is heated and when it is cooled. SMH - MCC Smart car concepts (electric & hybrid).
