Abstract
A heating or air-conditioning system for passenger cars is described that is equipped with a main heat exchanger comprising a ribbed-tube block against which the air flows that is guided into the passenger space and of a forward-flow radiator tank through which water flows and a return-flow radiator tank. The heating or air-conditioning system is also equipped with one or several additional panel radiators that are connected to an additional circulating system and are arranged so that they are distributed at or in the interior of the vehicle. This additional circulating system has a forward-flow chamber that is assigned to the return-flow radiator tank of the main heat exchanger. As a result, the advantage is achieved that the panel radiators, during the heating operation, can be acted upon directly from the main heat exchanger by a lower temperature. Also, the advantage is achieved that the panel heat exchangers in the cooling operation of the air-conditioning system, may also be used for cooling.
