Abstract

The invention relates to a method and an arrangement for regulating air mixing in a heating and/or air-conditioning system of a motor vehicle. In the system, recirculated air and/or fresh air is/are distributed via air-flow control elements to different air vents and supplied to the passenger compartment. In order to optimize energy consumption and provide a simpler and therefore more cost effective arrangement, the proportion of recirculated air is determined as a function of the position of the air-flow control element(s). The control unit is designed in such a manner, e.g., by implementation of a computer program, that signals being emitted by the control unit for opening the recirculated-air intake opening are dependent on, inter alia, the position(s) of the air-flow control element(s).
