Manual control of the ventilation, heating and air conditioning system Mercedes-Benz Vito W639

The Mercedes Vito heating (air conditioning) and interior ventilation system installed on the car effectively operates with the windows closed and is a single complex that provides the most comfortable conditions in the car, regardless of weather conditions and ambient temperature. The temperature in the cabin is controlled by mixing cold and hot air. The cooling unit of the air conditioning system reduces the temperature and humidity of the air, cleans it from dust. The heater increases the air temperature in all operating modes of the system.

The heating (air-conditioning) and ventilation system of the passenger compartment provides quick-response regulation of the air temperature, which is practically independent of the speed of the vehicle. The amount of air entering the passenger compartment is mainly determined by the mode of operation of the fan, so it must be turned on even while driving at high speed.

Depending on the configuration, a control unit for the heating (air conditioning) and ventilation system with manual control or an automatic microclimate control system (climate control) is installed on the car.

Outside air can enter the passenger compartment through the door windows with the windows down and the air intake located in front of the windshield.

The air from the air intake can enter the passenger compartment through the blower nozzles (windshield, side, center and bottom nozzles).

The direction of the air flow up and down is changed by turning the handle up and down.
