Abstract
A heating or air-conditioning system for a passenger cell of a motor vehicle has a heat exchanger which is arranged in the cooling water circuit of an internal combustion engine and through which an air stream passes. The system also has a supplementary electric heater through which the same air stream flows. The heat exchanger and supplementary electric heater are arranged in an air box, and have an electronic control unit for controlling heating or air conditioning. In order to give the heating or air-conditioning system a design which is economical in terms of installation space and which is easy to mount, the control unit is arranged downstream of the heat exchanger and the supplementary heater in the floor area of the air box. The supplementary heater is oriented at a right angle with respect to the control unit and makes contact with the control unit on its underside.
