ABSTRACT:
The invention relates to a heating or air-conditioning system for vehicle interiors having an air distributor which is connected to an air guiding duct and has air outlet openings for the lower plane of the vehicle interior. An air guiding duct with air outlet openings for a center plane of the vehicle interior is connected by way of a cold-air inlet with the cold-air duct and by way of a warm-air inlet with the air distributor. One cold-air or warm-air flap respectively is in each case assigned to the cold-air and warm-air inlet. The flaps are configured and disposed for the purpose of a faster cooling of the vehicle interior by the large-area flowing of cold air into all areas of the vehicle interior. On the one hand, the geometry of the cold-air flap swivelling about a swivel axis arranged in the center and, on the other hand, the arrangement of the swivel axis in the air guiding duct is defined such that, in its opening position completely opening up the cold-air inlet, the cold-air flap projects by means of its one longitudinal edge into the cold-air inlet and, by means of its opposite other longitudinal edge, rests against a wall area of the air guiding duct which, viewed in the air flow direction, is situated behind the warm-air inlet and, as a result, divides the cold-air flow flowing into the cold-air inlet into a partial flow to the center nozzle and a partial flow to the air distributor.
