A heating or cooling arrangement in a motor vehicle is provided with an equipment block, in which a heat exchanger, an evaporator, a condenser or a cooler are arranged on the inlet and outlet pipes. The heat exchanger, evaporator, condenser or cooler is slid into the equipment block as a preassembled heating or cooling unit. The equipment block is provided with clamping elements by which inlet and outlet pipes arranged on the heat exchanger, the evaporator, the condenser or the cooler in a preassembled manner are connected with the equipment block.

Heating or cooling arrangement in a motor vehicle

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.

Heating and air conditioning system for vehicles

A device for use in vehicles with electric or hybrid drive for monitoring the air conditioning of a vehicle based on health and energy consumption readings. The device monitors the operation of the air conditioning to determine when differentials between outside and inside temperature are excessive, and/or inside atmospheric humidity is too low and/or air quality is poor. An occurrence of any of these conditions results in the system suggesting to the driver that he should interrupt travel to the desired destination. In addition, if necessary, the device performs a vehicle range estimate as a function of the selected air conditioning operation.
