Ventilation, heating and salon air-conditioning

THE GENERAL DATA

Ventilation and heating

For regulation of temperature of air the system of mixing of cold and hot air is used. This system provides quick-response regulation of temperature of air which practically does not depend on speed of movement of the car. Intensity of giving of air in salon is defined by speed of rotation of the fan. Therefore if necessary the fan should be included even at car movement. For heating of a zone of an arrangement of feet of passengers on a back seat warm air is brought on the air lines located under a rug.

Central deflectors


Air can arrive in salon through both central дефлектора. Degree of giving of air is regulated depending on position of a regulator of giving of air placed between lattices. The direction of streams of air from central дефлекторов can be adjusted at will both in horizontal, and in vertical planes with the help рычажков which provide an inclination and turn дефлекторов.

Lateral deflectors

Air can arrive in car salon through left and right lateral deflectors.

Nozzles it blows lateral glasses of forward doors


Cold or warm air arrives on having blown both wind, and lateral glasses of forward doors (mainly in zones which provide visibility of external rear-view mirrors).

Central air of air of salon

Systems of ventilation, heating and air conditioning represent the uniform functional complex intended for maintenance of as much as possible comfortable conditions in the car during any season of year, irrespective of weather conditions and air temperature. The block of cooling of a central air carries out decrease in temperature and humidity of air, and also its filtration from a dust. The block of heating of system of heating provides air rise in temperature in any operating modes depending on position of a regulator of temperature. The quantity of air arriving in salon depends on a fan operating mode.

The conditioner switch

Control lamp

The button serves for inclusion and deenergizing of the conditioner of air.

Start the Engine, establish by means of the switch a demanded operating mode of the fan and press the button of inclusion of the conditioner. At conditioner inclusion the control lamp will light up. For conditioner deenergizing repeatedly press the same button.

It is necessary to mean that air conditioner does not join, if the switch of operating modes of the fan is in position OFF or air temperature more low 0 With.

The prevention

If air central air works during car movement on long liftings or in the conditions of intensive city movement, watch engine temperature. Conditioner work in this case can become the reason of an overheat of the engine. If the temperature of a cooling liquid exceeds admissible value, switch off air central air.

Ррегулятор air temperatures


The regulator provides smooth change largely temperatures of air arriving in salon of the car. Thus external air can be warmed up, be cooled or go to salon without temperature change. Moving of the handle of a regulator to the left increases inflow of cooled air (a blue zone). Moving of the handle of a regulator to the right increases inflow of the warmed-up air (a red zone).

The switch of operating modes of the fan


The switch is intended for a speed control of rotation of the fan. In total it is provided four operating modes of the fan.

Regulator of distribution of air


The regulator allows to establish a desirable mode of distribution of air arriving in salon.

Top level mode: air arrives in salon through central and lateral ventilating deflectors.

Two-level mode: air arrives in salon through central, lateral and bottom ventilating deflectors in a zone of an arrangement of feet of the forward passenger and the driver.

The bottom mode: air, basically, arrives in salon through deflectors in a zone of an arrangement of feet of the forward passenger and the driver.

Having blown in glasses: air goes on having blown wind and lateral glasses of forward doors.

The mode switch recycling air

Press the switch button at movement on strongly dusty district or in a dense transport stream to avoid hit in salon of the car of a dust and загазованного air. This mode can be useful also to fast decrease or air rise in temperature in salon. At mode inclusion recycling the control lamp and receipt in salon of external air lights up stops.

For mode deenergizing recycling air and renewal of ventilation of salon of the car it is necessary to press the same button repeatedly. Thus the control lamp will go out.

The prevention

It is not necessary to use a mode recycling air long time. It can lead to increase in humidity of air in salon and запотеванию glasses. Movement with the misted over glasses dangerously as visibility thus worsens and increases probability of road and transport incident.

The maximum mode of cooling of salon

It is recommended to use in hot weather and after long parking of the car on the sun. Open for short time of a window to air salon of the car from нагретого air.


The conditioner switch: it is included.

The mode switch recycling air: it is included.

Regulator of distribution of air:

Regulator of temperature of air: extreme left position (a blue zone).

The switch of operating modes of the fan: position 4.

Normal mode of cooling of salon

It is recommended to use at trips on a city and in the country.


The conditioner switch: it is included.

The mode switch recycling air: it is switched off.

Regulator of distribution of air:  or    .

Regulator of temperature of air: in a blue zone.

The switch of operating modes of the fan: at will.

Two-level mode of ventilation

It is recommended to use in inter-season period when the low temperature of air and not enough sunlight keeps.

If the regulator of temperature of air is established on average position (between blue and red zones), warmer air will arrive in a zone of an arrangement of feet, and colder – in the top part of salon of the car.

The conditioner switch: it is included.

The mode switch recycling air: it is switched off.

Regulator of distribution of air:.

Regulator of temperature of air: between blue and red zones.

The switch of operating modes of the fan: at will.

Ventilation

External air arrives in salon through the central and lateral ventilating lattices.


The conditioner switch: it is switched off.

The mode switch recycling air: it is switched off.

Regulator of distribution of air:   or    .

Regulator of temperature of air: at will.

The switch of operating modes of the fan: at will.

The maximum mode of heating


The conditioner switch: it is switched off.

The mode switch recycling air: it is included.

Regulator of distribution of air:.

Regulator of temperature of air: extreme right position (a red zone).

The switch of operating modes of the fan: position 4.

At condensation of a moisture and запотевании glasses switch off a mode recycling air.

Normal mode of heating

The conditioner switch: it is switched off.

The mode switch recycling air: it is switched off.

Regulator of distribution of air:

The conditioner switch: it is switched off or included.

The mode switch recycling air: it is switched off.

Regulator of distribution of air:.

Regulator of temperature of air: at will.

The switch of operating modes of the fan: at will.

The prevention

In avoidance запотевания glasses in rainy weather establish a regulator of distribution of air in position it blows glasses at receipt in salon of cold air from the outside (the heater is switched off). The difference of temperatures of air and a windscreen can cause moisture condensation on an internal surface of glass and deterioration of the review from the car.

Recommendations about conditioner operation

If the car was on parking under direct beams of the sun before including the conditioner, open windows and air salon.

That in rainy weather to clear the misted over glasses of a condensate, lower air temperature in salon, having included the conditioner. This reception is useful during a rainy season when humidity of air is very high.

At driving on a city with an intensive transport stream the air conditioning system effectiveness can decrease because of frequent stops and movement of the car with small speed

If air conditioner is not used long time (month or more), it is necessary to include once a week it for some minutes, even in the winter. Before inclusion of the conditioner of air start the Engine. Periodic inclusions of the conditioner promote preservation of a layer of greasing on details of the compressor and consolidations, and also prolong central air service life.

The compressor of a central air of air does not join, if the fan switch is in position OFF or air temperature more low 0 With.
