Abstract
A heating and ventilating apparatus for a motor vehicle includes a cold air admission duct supplying the admission and heating circuit in order to produce a stream of cold or heated air for introduction into the inlet of a distribution circuit having air outlet ducts which exhaust into different parts of the cabin of the vehicle. The apparatus includes a priority demisting duct which is separate from the distribution circuit, and which has an inlet communicating with the admission and heating circuit, together with an outlet which exhausts behind the windshield. A shut-off valve is displaced between a priority demisting position, in which it closes off the inlet of the distribution circuit, and a normal position in which it closes off the inlet of the priority demisting duct.
