Abstract
A heating or air conditioning system for a passenger compartment of a motor vehicle has a heat exchanger which is arranged in a cooling water circuit of an internal combustion engine and through which an air stream passes. A supplementary electric heater through which the same air stream can flow is also provided. In order to design the heating or air conditioning system in such a way that a separate installation space is not necessary for the installation of the supplementary electric heater, the supplementary electric heater is physically integrated into the heat exchanger. The supplementary electric heater includes a plurality of electric heating rod assemblies arranged between water ducts of the heat exchanger which extend parallel with one another along the air passage surface of the heat exchanger.
