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.

What is claimed is: 1. A heating or air-conditioning system for a motor vehicle, comprising: a housing; a heater that produces warm air situated within the housing, wherein the heater is located centrally within the housing and occupies the entire area within an outer periphery having a first lateral side and a second lateral side opposite to said first lateral side; first and second cold-air ducts formed in the housing, the first cold air duct located on said first lateral side and the second cold air duct located on said second side of the heater outer periphery, the cold-air ducts being configured to channel air into separate air streams that are each routed laterally around a different one of said opposed lateral sides of the outer periphery of the heater and each cold-air duct having an associated cold-air flap that controls air flow therethrough; and partition walls within the housing, the partition walls forming four independent 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, one of the partition walls dividing each of the cold air ducts into two separate cold air ducts, to define four independent cold air ducts with each cold air duct communicating with one of the air mixing chambers and having said associated cold air flap therein. 2. A heating or air-conditioning system as claimed in claim 1, wherein the cold-air flap is arranged at a mouth of the respective cold-air duct, and movable between an opened position and a closed position, the cold-air flap deflecting cold air toward warm air exiting the heater into the respective air-mixing chamber in its open position. 3. A heating or air-conditioning system as claimed in claim 2, wherein the cold-air flap is curved. 4. A heating or air-conditioning system as claimed in claim 1, wherein the lamellae of each warm-air control element in their open position deflect warm air laterally toward cold air entering the air-mixing chamber from the respective cold air duct. 5. A heating or air-conditioning system as claimed in claim 1, wherein the four heating/air-conditioning zones comprise a front driver side, a front passenger side, a rear right passenger side and a rear left passenger side of a vehicle. 6. A heating or air-conditioning system as claimed in claim 1, wherein the heater includes at least a heat exchanger adapted to have drive unit coolant of a motor vehicle flowing through it. 7. A heating or air-conditioning system as claimed in claim 6, wherein the heater further includes an additional heater arranged parallel to the heat exchanger. 8. A heating or air-conditioning system as claimed in claim 7, where the additional heater includes at least one electric heating element. 9. A heating or air-conditioning system as claimed in claim 1, wherein each cold-air duct is formed between one of said lateral sides and an interior surface of the housing. 10. A heating or air-conditioning system for a motor vehicle, comprising: a housing; a heater that produces warm air situated within the housing, wherein the heater is located centrally within the housing and occupies the entire area within an outer periphery having a first lateral side and a second lateral side opposite to said first lateral side; first and second cold-air ducts formed in the housing, the first cold air duct located on said first lateral side and the second cold air duct located on said second side of the heater outer periphery, the cold-air ducts being configured to channel air into separate air streams that are each routed laterally around a different one of said opposed lateral sides of the outer periphery of the heater and each cold-air duct having an associated cold-air flap that controls air flow therethrough; and partition 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. 11. A heating or air-conditioning system as claimed in claim 10, wherein one of the partition walls divides each of the cold air ducts into two separate cold air ducts, to define four independent cold air ducts with each cold air duct communicating with one of the air mixing chambers and having said associated cold air flap therein. 12. A heating or air-conditioning system as claimed in claim 11, wherein the cold-air flap is arranged at a mouth of the respective cold-air duct, and movable between an opened position and a closed position, the cold-air flap deflecting cold air toward warm air exiting the heater into the respective air-mixing chamber in its open position. 13. A heating or air-conditioning system as claimed in claim 11, wherein the four heating/air-conditioning zones comprise a front driver side, a front passenger side, a rear right passenger side and a rear left passenger side of a vehicle. 14. A heating or air-conditioning system as claimed in claim 10, wherein each cold-air duct is formed between one of said lateral sides and an interior surface of the housing. 15. A heating or air-conditioning system for a motor vehicle, comprising: a housing; a heater that produces warm air situated within the housing, wherein the heater is located centrally within the housing and occupies the entire area within an outer periphery having a first lateral side and a second lateral side opposite to said first lateral side; first and second cold-air ducts formed in the housing, the first cold air duct located on said first lateral side and the second cold air duct located on said second side of the heater outer periphery, the cold-air ducts being configured to channel air into separate air streams that are each routed laterally around a different one of said opposed lateral sides of the outer periphery of the heater and each cold-air duct having an associated cold-air flap that controls air flow therethrough; and at least one partition wall within the housing, the partition walls forming 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. 16. A heating or air-conditioning system as claimed in claim 15, wherein each cold-air duct is formed between one of said lateral sides and an interior surface of the housing.
