Abstract:
Heating or air-conditioning system for a vehicle interior comprising:an air distributor which is connected to an outlet side of a first air duct through which warm air can pass and which has outlet openings for air outlet directly from said first air duct, at least into a lower plane of the vehicle interior,a heat exchanger which covers an inlet side of said first air duct through which warm air can pass, an air guiding duct with outlet openings for the air outlet into a center plane of the vehicle interior which is connected, by way of a first air inlet through which cold air can pass, with a second air duct through which cold air can pass and, by way of a second air inlet through which warm air can pass, with the air distributor,a first air flap which is assigned to the first air inlet and which can be swivelled about a swivel axis arranged approximately at a center of the first air flap from a closed position completely closing-off the first air inlet into an opened position completely exposing the first air inlet and vice versa, anda second air flap which is assigned to the second air inlet and which completely closes off the second air inlet in one of two swivel end positions and opens it up completely in the other swivel end position,wherein the first air flap is configured and arranged with its swivel axis in the air guiding duct such that the first air flap, in its opened position, has one longitudinal edge which projects into and divides the first air inlet and an opposite other longitudinal edge which rests on a wall area of the air guiding duct which, viewed in the air flow direction, is situated behind the second air inlet, and, as a result, a partial flow to the second air inlet branches off a cold air flow entering in the first air inlet.
