Abstract: Heating, ventilating and/or air-conditioning system for a motor vehicle, comprising a control device (12), at least one functional component (16) and at least one driver device (14) which is implemented separately from the control device (12) and from the at least one functional component (16), wherein the control device (12) is connected to the at least one driver device (14) in terms of information technology by means of a bus system (18), and wherein the driver device (14) has at least one driver (24) for the functional component (16), which can operate the functional component (16)

Abstract: A vehicle heating, ventilating and/or air conditioning device (10) comprising a housing (12), in which at least two hot-air guiding ducts (18, 19) are formed for different vehicle interior regions, the hot-air guiding ducts (18, 19) being separated by a housing wall (28). A common heating device (30) and a common air treatment element (32) are provided which are arranged in each case in both hot-air guiding ducts (18, 19), the air treatment element (32) being arranged in the air flow downstream of the heating device (30). The air treatment element (32) has a dividing wall (34) which divides the air treatment element (32) into at least two part regions which are assigned to in each case one hot-air guiding duct (18, 19).

Abstract: Heating and/or air conditioning unit for a vehicle having a heat exchanger (2, 4), to the outlet side of which a temperature flap (10), a duct which serves, at least in sections, as mixing chamber and/or distributor, an air flow control flap (12) and an air outlet are connected, at least one section of the duct containing a partial air guide duct (22) running essentially parallel in a duct-inside-a-duct arrangement, making it possible to carry a proportion of the heated and/or conditioned air essentially without interference from other air flows.

Abstract: An air duct, in particular for a motor vehicle heating, ventilating and/or air conditioning system, which is acoustically optimized by virtue of the fact that at least one cross-sectional discontinuity is constructed by making use of a phenomena which occur as acoustic scattering processes at the cross-sectional discontinuity. The cross-sectional discontinuity should extend substantially perpendicular to the flow direction in the air duct.

Abstract: A device for the filtration of an airstream, in particular for a heating and/or air conditioning installation in a motor vehicle. The device provides, on one hand, a filtration that includes as much as possible of the entire airstream, while, on the other hand, for cooling and/or heating purposes, the device provides the entire air-conveying capacity without any air-output losses due to the filtration. The device includes a first outer air-channel containing fixed filter-wall parts of an activated carbon-filter arrangement, and a second inner air-channel containing second filter-wall parts of a particle-filter arrangement. The second filter-wall parts can be pivoted between an opening position which is essentially parallel to the first filter-wall parts and a closure position. Also included is a closure device at the exit of the outer air-channel, such that in the closure position, the entire airstream is conveyed at least through the filter-wall parts.
