➤ Installation of air conditioner Lada Granta liftback

As standard, cars of the Lada Granta family are not equipped with an air conditioning system. As necessary, owners install the equipment themselves, having previously purchased it from a car store.

The efficiency of the air conditioning system depends on the correct selection of the unit, its technical characteristics, power, and other indicators.

The cost of installing an air conditioner on Granta Liftback varies depending on the region, type of service station, and professionalism of the craftsmen. Minimum price 5000 rubles.

In megalopolises and large cities, the installation of air conditioning on the Lada Granta Liftback is 15 - 20% higher. Prevention, replacement of the air conditioner drain hose, refilling with freon from 1,500 rubles.

In car markets you can find cheaper units, the cost of which does not exceed 20 - 24 thousand rubles. Most likely, such equipment is not covered by a warranty; it is called disposable.

Components of an air conditioner

The thermostatic valve is located in the evaporator housing and is designed to reduce pressure. This phenomenon causes the refrigerant to boil in the evaporator. It should be noted that the device does not require configuration.

As for the receiver-dryer, this unit is used for liquefied refrigerant purification. Filtration is carried out using silica gel. Long-term depressurization of the air conditioning system requires replacement of the device. This is due to the fact that the dehumidifier in the Frost model, after refueling the system, is not able to fully perform its functions. The result can be the formation of acids and their destruction inside the air conditioning system.

The components of the structure under consideration are connected to each other by a pipeline. This product is made of aluminum alloy and has a single sealed circuit. During the operation of the vehicle, it is recommended to avoid possible dents or scratches on this pipeline. The moving elements of the air conditioner are connected to each other by special flexible inserts made of synthetic raw materials. These inserts can withstand pressures up to 30 bar. Each rubber pipeline connection is equipped with rings that are designed to improve sealing. It should be noted that these rings are disposable, so they require replacement when dismantling or disconnecting pipelines and inserts.

Installation method: certified service station or do it yourself

If we consider the issue from an economic point of view, then if you install it yourself, you can save 5–6 thousand. On the other hand, unprofessional work cannot guarantee long-term operation or elimination of defects free of charge.

Radiator and evaporator

Climate control in Granta involves the use of a multi-flow condenser. This device is located in front of the main radiator cooling the engine system. The radiator honeycombs are made of small aluminum tubes. It should be noted that the Frost air conditioner is designed as follows: the refrigerant passes through the system several times, while it changes its direction. A condenser is used to condense steam and remove refrigerant, which releases heat into the environment. The climate control system provides for the forced cooling fan motor to start when the air conditioner is turned on.

Important Notes

The air conditioner will turn on only when the engine is running, the interior fan is turned on at any speed and when the outside air temperature is not lower than minus 5 ° C
When the air conditioner is running, drops of water may appear under the bottom of the car - this removes condensed moisture from the air.
When the button is pressed, at least one of the central or side nozzles must be open, otherwise the air conditioner evaporator may freeze and cut off the air supply to the cabin.
It is recommended to direct the air from the ventilation nozzles slightly upward. Do not block the windshield and side window blower nozzles on the instrument panel, as well as the footwell blower nozzles of the front and rear rows of seats with various objects.
When the car is moving, the heater/air conditioning fan should always be turned on, at least at 2nd speed, to create excess pressure in the cabin in order to prevent dust and dirt from entering through leaks in the body, as well as to avoid fogging up the windows.
When washing a car, do not turn on the climate system fan.
When using the air conditioner in conditions of high air humidity and outside temperature from minus 3 ° C to plus 5 ° C, it is recommended to turn on the air conditioner fan at least at speed 3 to avoid freezing of the cooler.
Do not direct cooled air onto the windshield when the outside air humidity is high! This may cause the glass to fog up or freeze and impair your vision.
It is not recommended to direct the flow of cooled air onto the face and open areas of the body - this can lead to hypothermia and illness.
When the air conditioner is operating, the specific fuel consumption increases, because Additional power from the engine is required to drive the compressor.
Driving in mountainous areas or in difficult road conditions with a trailer may cause the air conditioning compressor to be switched off to prevent engine overheating. In this case, the air entering the cabin will not be cooled. To turn off the air conditioner, press the “air conditioner” button again, the indicator light will go out.

Conclusion

How does air conditioning work in Lada Granta?

A modern car air conditioner consists of the following elements:

condenser;
evaporator;
compressor;
connecting tubes;
auxiliary parts - sensors, wiring and fan.

The operating principle of the device is as follows:

When you press the A/C button in the Grant, the engine ECU receives a request to turn on the air conditioning. The ECU checks the system pressure using a refrigerant pressure sensor. If the result is satisfactory, the pull request is considered approved.
The compressor clutch closes. Through a belt drive, the compressor pulley begins to rotate together with the clutch and spins the compressor shaft. The cooling fan turns on at full power.
Freon begins to compress and enters the condenser under pressure through connecting tubes and hoses. Passing through the condenser, it cools and goes into the evaporator. The air near the evaporator begins to rapidly cool. The heater fan blows cool air into the passenger compartment.
Condensation appears on the evaporator in the form of moisture, which drips into a special drain pipe under the car. It is normal for water to appear under the car while the air conditioner is running.
If the permissible pressure in the system is exceeded, the compressor is switched off. As soon as the pressure returns to normal, it will turn on again. All this is accompanied by characteristic clicks under the hood.

Climate control differs from air conditioning only in that it is the control part of the climate system and can turn on the clutch when required.

These systems can work both together and separately, as, for example, in simple machines. The air conditioner is turned on manually.

About recycling

Recirculation is turned on using handle No. 3 (Granta, Kalina) or by pressing the arrow button in a circle No. 19 (Vesta, XRAY).

To speed up the heating or cooling of the interior after parking the car, you can turn on the recirculation mode for a short time; after reaching a comfortable temperature or when the windows fog up, you must turn on the supply of fresh air.
Prolonged use of the recirculation mode may cause the driver to become drowsy or drowsy and result in loss of control. Use recirculation mode only when necessary. It is recommended to preferentially use the supply air mode.
You cannot sleep in a car with recirculation mode on. This could result in serious injury or death due to reduced oxygen levels in the vehicle interior.
