In an air-conditioning installation for vehicles with a blower for supplying fresh air to a vehicle interior space, with a temperature sensor for detecting the interior space temperature and with an air jet pump, consisting of a venturi pipe and of an air suction connection for producing an air flow over the temperature sensor, the air jet pump is arranged integrated in the blower for reducing the individual components for the temperature detection and for reducing the requisite installation space in the vehicle in such a manner that its air outlet opening lies within the blower stream. The temperature sensor is thereby so arranged that it is acted upon by the interior space air sucked-in by way of the air suction connection.

Air-conditioning installation for vehicles

A system for the air-conditioning of the interior of a motor vehicle having an engine cooling circuit is provided which has a water/air heat exchanger and a water/water heat exchanger connected in series in the engine cooling circuit. The water/air heat exchanger is arranged upstream of the water/water heat exchanger. The water/water heat exchanger is between the water/air heat exchanger and panel heat exchangers which are located in the interior of the vehicle.

System for the air-conditioning of the interior of a motor vehicle

A heat exchanger for the independent heating of the driver and front-seat passenger side of a passenger space, having flow pipes located at the ends of the heat exchanger at the transition between the upper and lower water compartment. These flow pipes are connected to the central flow connection via a flow channel transverse to the central flow connection and corresponding juncture channel. The transverse channel is located above a collecting chamber which is located at the lower side of the upper water compartment. The flow pipes guide the flow from the upper water compartment to the lower water compartment. Return pipes are positioned to guide the flow from the lower water compartment into the collecting chamber in the upper water compartment. From the collecting chamber the flow travels out of the upper water compartment through return connections.

Heat exchanger for the independent heating of the driver and front-seat

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.
