摘要： The display glass of an indicating instrument which is placed in front of a displaying front plate is heated by the absorption of radiating heat which is emitted by the heating of the displaying front plate by PTC electrical resistance elements which are advantageously fastened at the displaying front plate's rear side. By way of this device that is simple and cost-effective in regard to construction, fogging is removed on a display glass of an indicating instrument and a repeated fogging is reliably avoided.

摘要： An air conditioning system for a preferably air cooled vehicle has a housing having an evaporator, a chamber and at least one blower. The housing, by way of outlet ducts having individually blockable defroster, center and legroom nozzles, is connected with a passenger compartment. By way of a warm air duct having an exhaust gas heat exchanger, the housing is acted upon by warm air, by way of an inflow duct having a fresh air flap controlled by an electric motor, it is acted upon by fresh air, and by way of an inflow duct for circulating air, it is acted upon by air from the interior of the vehicle. In this case, warm air and/or fresh air and/or circulating air, by way of a temperature mixing flap, is guided to a blower, is swirled together and mixed in it, and subsequently by way of the individual outlet ducts, is guided to the passenger compartment. In order to avoid air throughput fluctuations, the fresh air flap is controlled as a function of the driving speed of the motor vehicle, of the position of the temperature mixing flap, of a rotational speed step of the blower and of a switching condition of an electromagnetic clutch of a refrigerant compressor.
