The invention relates to a heating or air-conditioning system for a motor vehicle, by which individual zones of the vehicle interior can be supplied with separately temperature-controlled air. An improved heating or air-conditioning system, which requires just a small amount of installation space, feeds differently temperature-controlled air to a plurality of air-conditioning zones. Despite the small amount of installation space, optimum mixing of cold air and warm air takes place in the heating or air-conditioning system, with the result that the air emerging from air-outlet openings in a respective air-conditioning zone have a constant temperature over the outlet cross section.

1. A heating or air-conditioning system for a motor vehicle, comprising:a housing;a heater that produces warm air situated within the housing;two cold-air ducts formed in the housing, the cold-air ducts being routed laterally around both sides of the heater and each cold-air duct having an associated cold-air flap that controls air flow therethrough; andpartition walls within the housing, the partition walls forming four air-mixing chambers downstream of the heater in a direction of air flow, each individual mixing chamber including a warm-air control element that controls air flow therethrough and an air duct that feeds to an associated heating/air-conditioning zone, wherein the warm-air control element includes a plurality of moveable lamellae movable between an open position and a closed position to block heated air from the heater,wherein the lamellae of each warm-air control element in their open position are oriented to be partially open so as to deflect warm air laterally toward cold air entering the air-mixing chamber from the respective cold air duct.
