Abstract
A motor-vehicle heating and/or air conditioning device has a cold-air duct (12), a hot-air duct (14) housing a heating radiator (18), a mixing chamber (28) communicating with respective air outlets (24, 26) of the ducts, and mixing means which comprise at least one flap (30) configured in such a way that, when the flap passes from a “hot” position to a “cold” position, the shutter wall (34) of the flap first of all clears a region of the outlet (24) of the cold-air duct which is close to the outlet (26) of the hot-air duct, so as to promote the mixing of a cold airflow (F1) and of a hot airflow (F2).
