You can adjust the direction of air flows entering the interior of the deflectors using the regulators. Send the air in the desired direction by moving the levers of the deflectors left-right and up-down.

Air supply through side ventilation deflectors, located on the left and right on the control panel, can be completely discontinued. In order to close or open the side ventilation deflector, turn the knob that is located on the side of the deflector.

The deflector, located on the top shelf of the control panel, can be opened or closed using a lever, which is between central ventilation deflectors.

If one of the air distribution modes is turned on or, then in the upper position, the air lever will enter the car interior simultaneously through the central and upper ventilation deflectors. To stop the air intake through the upper deflector, completely lower the lever down.

For the functioning of the heating systems of the cabin and air conditioning, the car engine worked. The heater uses the hot coolant of the engine for heating the air entering the interior. If the engine does not warm up to a normal operating temperature, it will take a few minutes before in the cabin will begin to come warm air.

In the absolute majority of cases, the best results of the systems that provide a comfortable microclimate are achieved in the outdoor air survey mode. Long inclusion of the mode recycle airEspecially with non-working air conditioner, leads to fogging glass. Therefore, it is recommended to include air recirculation mode only if necessary and for short time, for example, when driving around the terrain with a smoke or contaminated atmosphere. Once the need to insulate the interior of the car from the atmosphere disappeared, turn off the air recirculation mode.

The outer atmospheric air enters the heating and air conditioning systems through the receiving grille, located in front of the windshield. Periodically clean the openings of the receiving lattice from the leaves and other garbage that makes it difficult to pass the air.

Guys and on me on the go, when I was driving with kondeem in the salon, the sharp smell of the type of wiring and condo is finished working. What is thinking?

Hello. And at the moment I have the same thing, the smell of something burnt and after found that the climate does not see. You have something bad luck. Temperature on Street 7. It was necessary to turn on.

Confressor Konduyuk Daughter. Notpor did not clean the radiator, he clogged, ultimately overheating the system is excessive pressure and here's the result! Now, under the replacement, the radiator and compressor. Although there may be a radiator!

Have a good time day. He will not be flown with you, the temperature of the condushka does not affect the temperature.

but on the sink, when the car was fingering, I heard how the condo and the air is a cool bleach.

I had it in the spring, but the degree was 10 somewhere, rain, slush. In the morning I started everything worked, I drove to the mother-in-law, went to her for half an hour, then came out, started, drove and feel straight stiffishly terribly and the windows sweat. I come on to poke the Condeye button (I have a sleeper-control), but nothing happened! In the evening, it climbed into the Internet, and a hundred there just did not read, I decided to also sign up for the service! BUT! In the morning, the machine was pleasantly surprised, condo works🙂

well, right now, it shows, tomorrow if I also go to the garage and check there.

below 4 will not turn on.

Where does this information come from?

on the street how many degrees? After 0 degrees, it will not turn on.

Heating, ventilation and air conditioning

The car, depending on the configuration, can be equipped with a system of heating, ventilation and air conditioning with manual control and automatic climate adjustment in the cabin - climate control system. The air into the car's salon can act through the central and side deflectors located on the instrument panels, as well as through the air ducts - to the feet of the driver and passengers.
The cabin air purification filter prevents dust and harmful particles in the air in the air.
It turns out the air from the salon to the trunk through the ventilation grids located in the shelf under the rear glass. From the trunk, the air comes out through the grilles under the rear bumper.

Side deflector of heating, ventilation and air conditioning system: 1 - lever changes in the direction of air flow direction; 2 - the intensity regulator of air intake.

Central heating, ventilation and air conditioning system deflectors.
The control unit of the heating system, ventilation and air conditioning is located on the center console of the instrument panel.

The control unit of the heating system, ventilation and air conditioning (on car controlled vehicles): 1 - air temperature controller; 2 - switch mode of the heater fan operation; 3 - air flow distribution regulator; 4 - the air conditioner switch button; 5 - Air Recycle Recycling Switch.
By turning the handle of the air temperature controller 1, change the temperature of the air entering the interior. To increase the air temperature, you must rotate the knob of the regulator to the right, in the red sector of the scale, and to reduce the air temperature - to the left, in the blue sector. The intensity of air supply to the salon is regulated by turning the handle of the fan operation mode switch 2. In this case, one of the four fan rotation rates are turned on. Turning the knob of the switch clockwise, increase the speed of rotation of the fan. Air flows entering the salon can be adjusted. The flow distribution regulator 3 sets the following direction of air multiple air in the cabin:
- Air flow through deflectors in the instrument panel enters the top of the car's interior;
- The air flow comes only to the driver's location zone and passengers;
- the air flow enters the location zone, as well as to the lattices of blowing windshield;
- The air flow comes only to the lattices of windshield blowing.
To enable air recycling mode, press the switch button 5. In this case, the indicator lights up the button. To turn off, press the button again. Air recirculation mode (termination of the outdoor air supply to the cabin) It is recommended to use if necessary to quickly reduce or increasing the air temperature in the cabin, as well as when driving on dusty terrain or in a dense traffic flow to avoid dust, exhausted gases and unpleasant odors.
It is not recommended to use recycling mode for a long time, as this may lead to an increase in air humidity in the cabin and fogging glass.
To turn on the air conditioner, press the 4 switch button with the engine running and the heater fan turned on. In this case, the indicator lights up the button.
Re-pressing the button turn off the air conditioner. The air conditioner is also turned off when the heater fan is turned off. On the protracted lines or in the conditions of intensive urban motion, the operation of the air conditioner can lead to overheating of the engine. Therefore, if the cooling fluid temperature exceeds the allowed value, the air conditioner should be turned off. If the car is put on the parking lot in the right rays of the sun, before turning on the air conditioner, you must open the windows and ventilate the interior. To avoid fogging in rainy weather, you need to set the maximum fan speed, turn on the air conditioner and transfer the air flow distribution regulator to the position, while the air temperature controller is recommended to be installed on the border of blue and red zones.
After a long parking lot in hot weather in the sun When the air conditioner is turned on, do not direct the flow of cold air to the windshield in order to avoid cracking.
If there is no need to use the air conditioner, it must be included every month for several minutes, and even in the winter period of operation (during thaws).
This contributes to the preservation of lubrication on the parts of the compressor and seals, which extends the service life of the air conditioning system.
The car can be equipped with climate control system, which automatically controls the temperature, quantity and distribution of air flow and regulates them depending on the conditions specified by the driver, as well as weather conditions. This saves the ability to manually control the system.
The climate control control unit is located on the center console of the instrument panel.

Climate control control unit: 1 - fan rotation speed regulator; 2 - information display; 3 - air temperature regulator; 4 - air conditioning power button; 5 - the air recirculation mode button; 6 - buttons distribution of air flows in the cabin; 7 - Inea / moisture removal mode button on windshield; 8 - button on the automatic microclimate control system.

Pressing button AUTO. Includes automatic mode at which the set temperature in the cabin will be maintained automatically. When you press any of the climate control buttons, the automatic mode changes - the button is on, the function will be managed manually, the remaining functions are automatically. Turning on and off the air conditioner is carried out by pressing the button 4. When the air conditioner is turned on, the inscription will appear on the display. AC. The fan rotation speed is adjusted by the rotation of the regulator 1. The fan settings are displayed on the display in the form of strokes. The direction of air flows in the cabin are set by buttons 6. Button 5 is used to select the feed mode to the car of the outdoor air and recycling, when the feed in the outdoor air interior is stopped. To remove an inlet / moisture from the windshield, a button 7 is intended. When you press this button, the air conditioner will be automatically turned on, and the air recirculation is disabled. In this case, automatic control of the frequency of rotation of the fan and air temperature in the cabin occurs.

REAR VIEW MIRRORS

Depending on the configuration on the car, outer rear view mirrors can be installed with manual or electrical drive and heated. The position of the outer rear view mirror with manual drive is adjustable from the car's interior with a turn of the mirror handle. To adjust the position of the rear-view mirrors ...

... The driver's door armrest is located.
To adjust the position of the left or right outer mirrors, we translate (with the ignition turned on) the knob of the regulator, respectively, to the position L. or R.. Then, tilting the handle to the right and left and back and forth, change the position of the mirror. To turn on the heating of the mirrors, we translate the knob of the regulator to position 1.
When the electric drive fails, the mirror position can be adjusted manually by pressing the edges of the mirror element. The position of the inner mirror of the rear view can be adjusted in horizontal and vertical planes, turning the mirror body on the hinge. There are two modes of the position of the inner mirror: "Day" and "Night". To reduce the blinding action of the headlights of moving from behind, we translate the mirror to the "Night" position ...

... moving back the lever located at the bottom of the housing.
In this case, the angle of reflection of the mirror and the blinding effect decreases.
It is not recommended to place items on the shelf in front of the rear glass that can reduce the viewing zone through the mirror.

Salon lighting plander

In the upholstery of the ceiling of the car, the plane is installed, in which the interior lighting lamp and two directional light bulbs are located.

Salon Lighting Plafof: 1 - Fixture Lamp Switch Button; 2 - key switch lamp lighting of the cabin and directional light; 3 - section of the direction of directional light; 4 - section of the interior lighting lamp.
When you press the 1 button in the ceiling, the corresponding directional light lamp lights up. When you press the lamp button again goes out.
When not pressed (average position), the key 2 lamps of the interior lighting and directional light are automatically lighting up when the car is unlocked, opening one of the doors or removing the key from the ignition lock.
The lighting turns off after a few seconds after all the doors are closed or immediately after turning on the ignition. When you click on the right edge of the 2 keys, all the lamps of the ceiling light up. To turn off the plaffone lamps, press the left edge of the key 2. In this case, the directional light lamp can be turned on by pressing the corresponding button 1.

it became warm how to properly use recycling in VW Polo Sedan so that there is no sweat

Veronica Recycling is not intended to combat the fogging of glasses.

Victor first understand yourself what the term mean. And everything will become intuitive.

Inna So that it is necessary to put a fence of the air from the street.

Lily so that when the recirculation is turned on, the glass does not sweat, it is necessary to turn on the air conditioner. It will dry the air. I often go in summer, but no smells from the street comes, and there is a better condo, because you don't have to cool new portions from the street every time.

My review about "Polo Sedan"

Six months have passed since the purchase of the machine - VW Polo Sedan. Mileage 5800 kilometers.

Russian "Volkswagen"
As you know, Polo Sedan has developed specifically for the Russian market, and they also collect it in Russia, at the VW plant in Kaluga. The quality of the assembly is beautiful. If on the forums about other foreign cars collected in Russia, you can meet feedback on the fact that in the cars received there and there are shoals of the type of barbecues or missed parts, then everything is done very carefully and smooth. There are no differences from the "European" hatchbacks polo.
However, I still found marriage assembly, and what else! As soon as the spring rains went and slush, there was a presequitable thing: in crude weather when the air conditioner is turned on, from somewhere from under the buckage on the front passenger rug, as if under pressure was injected somewhere 100 ml of water. The situation was repeated periodically, apparently, as the water set somewhere inside the car.
In May, I went to the official service, Avilon. They checked the drainage there (it turned out to be in order), poured the car with water on the sink - did not find anything, the effect was not repeated (I suspected, I poured little). I planned, inviting to drive into the rain, how water will be on the rug again. At home, scratching turnips, I decided not to wait for the weather from the weather. After all, it can not be on tens of thousands of cars collected on the conveyor only I have such a defect? Sent through the form on the website VW.RU, a message to Russian "Volkswagen" with a description of the problem and asked me to send me to such a service that has experience to eliminate such faults.
Four days later they called me from Volkswagen and said that the defect would fix the same "Avilon" - they will give him relevant recommendations. Then they called from the service, invited to call. Interestingly, the representative of "Volkswagen" arrived at the service of my car. As a result, it turned out that when assembling my car at the plant, they forgot to cry the seam, going under a plastic apron, to which the "wipers" fall. Water penetrated through this seam, causing the problem described. Seam sealed, and - now there were already two strong rain - everything seems to be in order.
Representatives of the service swore and it was that the defect is in fact very rare. In general, it can be believed to believe, since "Avilon" is one of the largest VW centers in Moscow and with their volumes they would definitely be faced with this problem if it were more or less mass. In addition, at the request of the representative "Volkswagen", the place of repair was photographed - obviously, with an ordinary malfunction they do not come, followed by orgvoda.
There are no problems otherwise. Even the light bulbs are not burned.
Engine and transmission
On the Polo, the sedan put one engine - a regular atmospheric of 1.6 liters and a capacity of 105 hp, and a mechanical or automatic 6-speed gearbox (I have the last one). When I chose what kind of car model in general, this engine seemed to me nonselveny: Koreans, for example, in Hyundai Solaris and Kia Rio put engines of the same volume, but the capacity is already 122 forces. But it turned out that Korean "Horses" somehow Dholese German: their more numerous herd develops almost the same torque (155 nm against 153 nm in polo), and at 4,200 revolutions per minute, while polo - with only 3800 turns .
It is believed that with the "automatic" you need to put engines more powerful, strength of 150. Otherwise, like, "not going". Nonsense! 105 hp Polo in combination with an automatic box allow you to be completely efficiently controlled with the machine. Rebuildings, overtaking, sharp jerks in the formed spaces in traffic jams - no problems. And it is even in simple mode of operation of the box, and there is still a sporty ("s"), in which the transmissions switch up slower, and down - faster, so it's generally fire. In both modes, the reaction to the gas pedal is adequate: you press the average - the machine immediately dials the move, click "in the floor" ("Kikdown") - pause 1-1.5 seconds, switching the transfer down and jerk forward. No sensations like "does not go" no and close.
Yes, by the way, who doubts that choose when buying a car - mechanics or automatic - personally for me mechanics now (polo - my first car with automatic machine) died. Automatic box is simply incomparably more comfortable. And the conversations of the type "I love to feel the car" is, in my opinion, from the category of conversations about the "warm tube sound". On the automatic box at VW, by the way, there is a manual mode - pull the handle, switching the transfer up-down. Well, I tried it, well, it works. Just why? So did not use them more.
Comfort and Other
The relative budget of the machine imposes certain limitations. Noise isolation is weaker than the next class machine - "Jetty", the sound of the engine is not so muted. But, nevertheless, noise in the cabin is quite acceptable, talk and hear the interlocutor 120 kilometers per hour can not be strained.
The desire for marketers "Volkswagen" emphasizes the differences between the polo from other, more expensive models in places comes to funny (with sadness). For example, I have in the car there are such expensive options as climate control, leather multi-glass, heated windshield, ESP system, side airbags. But but there is no lighting lamp for the rear passengers (kopeck after all the plafof!). Also, they also saved on the again a muster backlight of the glover (I do not care, I do not use it, but the people in the forums are in the forums). Highlighting the trunk (if such a booze went) is.
Full tape recorder and acoustics were very pleased. Of course, I am not a maniac (see "Warm Lamp Sound"), but somehow I have no desire to improve. Here, however, on individual songs, where the low frequencies are specific, the sheathing of the doors begins to resonate. It is probably necessary to make noise insulation still.
The stove is weak. At temperatures below -10, the salon warms up long: only after 15 minutes in it in it can be located without a hat, and after 15 it becomes quite comfortable. But this is a lack of many cars, including much more expensive, so this evil is inevitable.
In general, impressions are mostly positive.

What do you need to do with air conditioning in winter? | All-Russian Club ...

4 Apr. 2015 - All-Russian Volkswagen Polo Club Sedan ... The air conditioner does not work if the temperature is below 4 degrees, even though it will not work, so ... I do not turn on Candert in winter. .... I tried the window to sweat the window, without kondey did not shove, I turned it on immediately.

POLO SEDAN SEDAN CONSTRUCTION SYSTEM. The heater nodes and the air conditioner heat exchanger heat exchanger are connounted in one block. Air conditioning system controls are located on the panel, common with heater controls.

The schematic diagram of the refrigerant movement in the air conditioning system is shown on a schematic figure below.

Circuit diagram of refrigerant movement in air conditioning system: 1 - combined pressure sensor; 2 - a plot of high pressure pipeline; 3 - Receiver-desiccant; 4 - High pressure line service valve; 5 - condenser (air conditioner radiator); 6 - condenser fan and cooling system radiator; 7 - air conditioning compressor; 8 - Low Pressure Pipeline section; 9 - service valve lines of low pressure; 10 - heater fan; And - evaporator; 12 - thermostatic valve

The compressor is installed on the engine cylinder block and is driven by a lyclinic belt, the compressor provides the refrigerant circulation in the system. The compressor shaft is installed in the aluminum front cover of the housing on the bearings and is sealed from the drive side of the drive with the gland.

Compressor drive pulley set to two<рядном шариковом подшипнике и при работающем двигателе постоянно вращается крутящий момент передается от шкива к валу компрессора через ведомый диск.

Notes

If the system is properly, while the air conditioner is turned on, the clutch is a clamping clutch disc under the action of an electromagnet comes into engagement with the pulley of the drive, and the compressor rotor begins to rotate.

But during the operation of the air conditioner, the following compressor faults may occur.

1. If, when the air conditioner is turned off, there is extraneous sounds during rotation, the smell of Gary is heated or appears, it probably began to collapse its bearing. In this case, it is necessary to replace the bearing. In some launched cases, it may be necessary to replace the compressor coupling assembly or components of its parts.

2. If after switching on the air conditioner, it is not audible, then the following problems are possible:

• refrigerant leakage occurred, and the control system blocks the inclusion of the compressor;
• the pressure sensor in the system has failed;
• malfunctions in electrical circuits of the control system;
• the winding of the coil of the coupling electromagnet burned;
• the engine control unit for any reason (high engine cooling fluid, high engine speed) blocked the enable compressor.

3. If the coupling rotates easily and freely, but when you turn on the air conditioner, extraneous noises are clearly audible or even stalls the engine, then most likely jammed the compressor. The inner pumping part of the compressor is not subject to repair. In this case, the compressor will have to be replaced.

4. And the last, the most unpleasant option. Click is distributed, the coupling easily rotates the compressor shaft, and the cooling of the air in the cabin does not occur. In this case, the compressor works in a frightened, nothing pumping. Only an experienced specialist in the presence of special control and diagnostic equipment can determine this malfunction.

You can most accurately determine the cause of the malfunction after complete diagnosis in a specialized service center for the repair of automotive air conditioners.

At the bottom of the rear compressor cover, an emergency pressure reset valve is set. In the case of pressure growth in the system while refusing a pressure sensor or other abnormal situations, when the installed maximum pressure of the valve membrane is destroyed and part of the refrigerant is ejected to the street as a rule, after which the emergency valve does not have sufficient tightness. Therefore, after eliminating the causes that caused pressure and reset the refrigerant, the valve is subject to a mandatory replacement.

A WARNING

When the valve is triggered, the refrigerant is unexpectedly ejected by strong jets in all directions. To prevent injury, people were closed by a cap.

Condop (air conditioner radiator) multithreaded type is located in front of the radiator of the engine cooling system. It is attached using brackets to the cooling system radiator. Condensor cells are made of flat thin-walled aluminum tubes with internal longitudinal partitions for rigidity and outer fins to improve heat exchange. Aluminum tanks, with flanges for connecting pipelines and receiver. In height, the tank is divided into sections, so passing through the condenser, the refrigerant flow changes several times the direction. In condensor, the steam condensation of the refrigerant compressed by the refrigerant compressor and the heat of heat released into the surrounding air occurs.

When the air conditioner is turned on, the engine control unit turns on the power supply circuit of the electric fan of the engine cooling radiator, which improves heat exchange in the condensor and reduces the pressure in the air conditioner system.

Evaporator Located in the block and air conditioning of the cabin. The evaporator is made of aluminum tubes with outdoor fins to improve heat exchange. Passing along the tubes of the evaporator, the boiling refrigerant actively absorbs heat from the air that blows the outer feeff surface of the tubes. The air is cooled and the fan is supplied to the interior of the car.

On the side surface of the evaporator there is a flange for mounting the thermal control valve.

Thermoregulation valve Block type is located in the evaporator case. The valve is attached to the pipelines and the evaporator using flange connections passing through the throttling hole in the valve body, the liquid refrigerant sharply reduces its pressure and begins to boil. In the valve case, an adjusting element is installed, changing the flowing section of the throttle opening, depending on the pressure and temperature of the refrigerant. The adjustment element is configured on the WPC-de-manufacturer and during operation the adjustment is not subject to.

Receiver-desiccant Mounted on condense on the left side and is a collapsible block. Inside the case there is a filter element (cartridge) filled with desiccant granules (silica gel). A liquefied refrigerant passing through the receiver is cleaned from possible impurities, dirt and moisture. At the top of the receiver case, a hole is located to replace the filter element.

Pipelifiers Connect all the elements of the air conditioning system into a single hermetic circuit. Pipelines and fastening flanges are made of aluminum alloys.

Wrap metal parts of pipelines from dents and beggars. Any narrowing of the pipeline cross section leads to a decrease in system performance.

To connect the intercommunicable elements of the pipeline system, some areas are equipped with flexible inserts (Fig. 12.3) from synthetic materials.

In places of compounds of individual elements of the system installed sealing rings Round cross section of neoprene. During the repair of the system, when separating pipelines, sealing rings are subject to mandatory replacement. Threaded pipelines tighten the recommended point. Weak or excessively severe tightening leads to deformation of the sealing surfaces and refrigerant leakage.

Service valves To connect diagnostic and refueling equipment are located on pipelines.

Valves are closed with threaded caps to protect them from dirt.

Sloves are installed in the valves, similar in design with spools of tires of wheels, but differ from them.

Special key is used for turning and screwing the spools.

Pressure meter Mounted in the engine compartment on the high pressure line pipeline.

By sensor signals, the electronic motor control unit turns off the air conditioner compressor when the system is deployed or an emergency increase in pressure in it in order to protect the compressor from overloads.

Control unit panel The ventilation, air conditioning and heating of the vehicle is installed on the instrument panel console.

Air temperature sensor In the cabin is located in the front panel of the control unit, if the climate control system is installed on the car. To exclude incorrect readings of temperature values \u200b\u200bdue to the effect of heated elements of the panel, the sensor is equipped with a compulsory blowing system. The system provides a uniform air duct from the front of the car's interior through the sensor housing. For normal air movement, protect the input hole of the sensor housing from any solid particles or fluid. This is especially true of cases of chemical cleaning of the cabin. During the cleaning of the salon, the vacuum cleaner is strictly forbidden to bring the suction tip of the vacuum cleaner pipe to the sensor inlet. With a difficult airbone through the sensor housing, the normal functioning of the automatic climate control system is broken.

Outdoor temperature sensorAlthough it is located in the front of the car behind the rubber cladding in a protected from solar radiation and ventilated location, exposed to such factors as warm air from the engine and radiation from the heated asphalt. Therefore, its testimony can sometimes be somewhat overestimated, especially after a long idleness in traffic jams. The appearance of the outdoor air can be considered correct when driving at a rate of at least 40 km / h for at least 10 minutes.

To improve the efficiency of the climate management system and a more comfortable distribution of air flows in the cabin, a solar illumination sensor is installed. Depending on the degree of heating the cabin with the rays of the sun along the sensor signals, the air flows are sent to the head or foot of the driver and the front passenger. The sensor is located on the instrument panel near the windows glass.

Refrigerant. The system is refilled by the HFC134A refrigerant (R134A). The refrigerant added special oil for lubricating the compressor is strictly forbidden to use the refrigerants and oils of other types in the system.
