ABSTRACT:
A heating and ventilating apparatus for the cabin or passenger compartment of an automotive vehicle includes a cold air transmission branch and an air heating branch, communicating with each other through a mixing zone and leading respectively to a de-icing port for the windshield of the vehicle, aerators or cabin vents at the level of the fascia panel, and lower outlet ports in the lower part of the cabin. A direct guide duct is arranged with its inlet penetrating partly into the outlet of the air heating branch, and with its outlet opening in the vicinity of the de-icing port, which allows warm air coming from the air heating branch to be mixed with the pre-mixed air coming from the mixing zone.
