Climate in the car
Various and precise adjustable heating and ventilation systems prevent annoying fogging of the windows and relieve the driver of premature fatigue when properly controlled. The supply of fresh air and forced exhaust ventilation are thus a prerequisite for optimum climate conditions in the vehicle.
Purpose of heating and ventilation
The air moving in front of the windshield enters through the fairing grille and is forced, if necessary, by means of a fan into the interior of the car body. Depending on the position of the valves in the heater housing, fresh outside air rushes to the aluminum plates of the heat exchanger, which looks like a small radiator, and heats up there. The air heated in this way flows through individual air nozzles and, accordingly, heating holes into the vehicle interior.
