Heating (air-conditioning) and a blower

Ventilation systems, heating and air conditioning installed in the car function effectively with the windows closed and constitute a single system that provides maximum comfort in the car, regardless of the weather conditions and the ambient temperature. The temperature in the cabin is regulated by mixing cold and hot air. The cooling unit air conditioning system lowers the temperature and humidity of the air, cleans it from dust. The heater increases the temperature of the air in all operating modes of the system.

The system provides quick-response control of air temperature, virtually independent of vehicle speed. The amount of air in the passenger compartment is mainly determined by fan operation, so it is necessary to include even while running at a high speed.

Outside air can enter the room through the windows of doors at the open window and blower, located in front of the windshield. Air from the blower can enter the interior of the vehicle through the air vents of the windshield, the side and center nozzles and lower nozzles through the heater housing.

Volume, temperature, direction and intensity of air flow is controlled switches installed in the control unit of heating, ventilation and air-conditioning.

The direction of air flow through the side and the central nozzle can be changed by turning the deflectors (vertical direction) and the flaps (horizontal direction).

To change the temperature of the air in the passenger compartment turn the knob temperature controller. The blue part of the scale corresponds to the maximum supply of cooling air, the red - the most heated. When the average position of the handle in the cabin is supplied with air at ambient temperature.

To increase the intensity of the air in the cabin while driving and ensure air supply to the stationary vehicle switch handle switch one of four modes of the fan blower.

To change the direction of air flow control knob to select air distribution is one of the four options (clockwise):

- Feeding air into the upper compartment (through lateral and central nozzle instrument panel);

- Feeding air into the upper and lower part of the cabin (through lateral and central dashboard nozzles and lower nozzles through the heater housing);

- Feeding air into the lower part of the compartment (through the lower nozzle housing heater);

- Supply of air to the windscreen (via the air vents of the windscreen).

To cool the air entering the interior of the vehicle, press the button on the air conditioning (if installed on the vehicle) - is lit green indicator lamp. To turn off the air conditioner to re-press the button.

To activate recirculation move the choke lever to the right recirculation. When the recirculation mode the outside air does not enter the room, and the fan blower circulates the air inside the cabin. This mode is used to quickly warm the interior in the cold season, as well as increased dust and gas content of the ambient air.

Depending on different combinations of switching control unit switches the heating and ventilation system works in the following main modes:

- The maximum cooling mode. Used in hot weather, and after a long parking in the sun for a quick cooling of the interior air. In this case, before turning on the air conditioner is recommended to open the windows for a short time to remove the hot air from the passenger compartment.

Switches the air conditioning and recirculated air should be included;

- Normal cooling. It is used when traveling around the city and in the country at a moderately warm weather. C switch must be turned on, the switch recycling - off;

- Ventilation mode. It used in the off-season, which is characterized by low temperature and lack of sunlight;

- The maximum heating mode. It is used at very low ambient temperatures and to quickly warm the air in the cabin after a long stay. C switch must be turned off, the switch recycling - enabled;

- Normal heating mode. It is used during the cold season to maintain optimum air temperature in the cabin after an intense warm-up mode, maximum heating. Switches the air conditioning and recirculated air should be turned off;

- Mode of blowing glass windshield and front doors. It is used to quickly remove misting at high humidity. C switch may be in any position depending on the ambient temperature, and the switch must be turned off recirculation.
