Abstract
An air conditioning unit for a vehicle is inserted between an inlet conduit (12), supplied with fresh air and/or recycled air, and the passenger space of the vehicle. The unit comprises a fan (16) which supplies two conduits placed parallel, of which one (19) permanently heats the air by contact with a heating component (21, 22), the heated air being dispatched either into the passenger space, or towards the exterior with the aid of a valve (25). The other conduit (20) is opened or closed by a valve (27), according to whether one wishes to cool or to heat the passenger space. The heating component (21, 22) is thus permanently cooled, both when the passenger space is heated and when it is cooled.
