Abstract: A heating and air-conditioning system for a motor vehicle has a conditioning housing that includes a connecting section which is provided with at least one air outlet opening. Using connecting structure on the connecting section, the air outlet opening may be connected to either an attachable rear vehicle compartment temperature-control unit or closed tightly, in a leak-proof manner, by a removable covering part.

Abstract: A heating and air-conditioning unit includes a heating unit, at least one cold-air duct guided around the heating unit, and air-mixing spaces downstream of the heating unit. At least one partition separates the mixing spaces into which cold and heated air can each be controllably introduced by air-flow control elements. As a result, air which can be temperature-controlled separately, can be supplied to at least two zones. To minimize the structural space occupied by the unit, at least one first partial air stream flows through a first assigned subregion (22VR and 22VL) of the heating unit (22) in a first direction, and at least one second partial air stream flows through a second assigned subregion (22HR and 22HL) of the heating unit (22) in a second direction opposed to the first direction.

Abstract: A four zone conditioned air unit for use in a motor vehicle providing heating or cooling to a plurality of regions having relatively independent temperature setting. The structure provides compact, flexible and convenient temperature conditioning for each region.

Abstract: A heating and air-conditioning system for a motor vehicle having a conditioning housing in which at least one heat exchanger is integrated and which has a plurality of air outlet openings for guiding air to front interior zones of the motor vehicle is known. According to the invention, the conditioning housing has a connecting section which is provided with at least one air outlet opening and is intended for connecting to an optionally attachable rear temperature-control unit which, when not utilized can be tightly, in a leak-proof manner, closed by a removable covering part.

Abstract: A heating or air-conditioning unit for a motor vehicle includes a heating unit for generating heated air, at least one cold-air duct guided around the heating unit, and air-mixing spaces provided downstream of the heating unit in the direction of flow. The mixing spaces are separated from one another by at least one partition and into which cold and heated air can be introduced in each case in a controllable manner by means of air-flow control elements, in order to mix the air in each mixing space to a certain mixing temperature. It is thereby possible to supply air which can be temperature-controlled separately to at least two air-conditioning zones.

Abstract: An air-conditioning unit for a motor vehicle comprises a housing having arranged therein, a blower, an evaporator of a cooling unit, and a heater heat exchanger. The evaporator and the heater heat exchanger are arranged downstream of the housing in terms of the airstream, and a plurality of discharge connection stubs which are arranged downstream of the heater heat exchanger are provided in the housing. In order to achieve the smallest possible space requirement and to subject the air channeling to the smallest possible changes in direction, the evaporator and the heater heat exchanger are arranged in the housing in the form of a V with respect to one another, such that respective ends thereof rest closely together in the vicinity of an initial section of the blower spiral.

Abstract: Heating and/or air-conditioning system for a motor vehicle which has at least two air flaps mounted along a common pivot axis in a housing. For independent control of the air flaps, transmission elements located coaxially with respect to the pivot axis are associated with the two positioning devices.
