In fact, not so many drivers are familiar with this regime and know about its useful and negative sides.

Air recycling in a car is a fence and "distillation" of air masses directly from. At the same time, the air is reduced by cooling, passing through the climatic installation, and after passing, it is distributed over air nozzles to supply to the salon.

pros

When using this mode, a decrease in the air temperature in the cabin is carried out in faster lines, rather than the air massersion mode from ambient. Basically, this is due to the repeated passage of air in the car, the temperature of which is lower than the environment, through the climatic installation.

With the reverse procedure - heating, it is still simpler, since the temperature in the cabin is much higher than outside the car.

Another positive point is the fact that the cost consumption of the compressor is significantly lower than when the outside fence.

Recycling is also an indispensable regime for people sensitive to road dust, floral pollen, unpleasant odors and other allergenic factors.

As an example, it is worth mentioning the situation that is probably familiar with any driver - this is a kamaz or any other car in front of you, issuing strong specific smells, recycling in this case - This is a great way out.

Minuses

To negative air recycling factors should include one very important moment - This is the absence of any air exchange. If simple words, you have to breathe the same air.

With prolonged use, the occurrence of the fogging of glasses is inevitable due to increased humidity in the car cabin. Many solve this problem of joint and recirculation regimen.

Where is the power button

The location of the recycling button varies depending on the model of your car, but there are two generally accepted designations (icons), with which they will not be founded.

Buttons look like this:

These designations are characteristic, unfortunately, not for all models. For example, on the "vases", the recycling button looks like a circle of three lines and is located on the left of the temperature regulator. Or maybe it can look like the arrow circle.

For those whose car, the question of using or non-use of this regime is largely disposed of itself, as it takes care of the purity and temperature of the air.

The principle of recycling is applicable not only to cars, but also is actively used at home and in industrial spheres.

For example, embedded hoods in the kitchen, which work on the same principle, which has been described above, allow you to connect to a stationary ventilation pipe, but are engaged in integrated filters.

Ventilation and heating VAZ 2109

As is known, on the VAZ 2109, the interior heating is provided by air heated by the radiator. On VAZ 2109, heating and ventilation of the cabin are interconnected and represent a certain special system.
In this article, we will look at the general principles of the system of heating and ventilation VAZ 2109.

Heating system

As a rule, the heating system of the car VAZ 2109 consists of several basic elements and nodes carried out below.

Heater

The heater itself or stove is the main link in the heating system. It is fastened with 4 nuts in the car's cabin under the bolts.
Air ducts are installed on the stove, which are fixed to the instrument panel from below. Sealing gaskets are required in their designs.

What is the stove

The heater of the VAZ 2109 consists of:

• 2 plastic shells connected to each other brackets (fastening brackets are connected around the perimeter);
• Special harness laid in the grooves for sealing;
• Electric fan, which forcibly delivers air to the cabin and is fastened with screws over the stove;

Note. The motor is installed on the stove so that its dismantling is convenient and did not cause any difficulties.

• Heating radiator, which is installed in the heater's casing;
• Crane;
• The cooling system pump, which carries out the circulation of fluid through the radiator;
• Handles stoves that allow you to manage the heater.

Control knobs stove

It is possible to achieve the most comfortable conditions in the cabin, if you move the stove control knobs and adjusting the position of the nozzles in the following way:

• The upper right handle adjusts the air supply to the feet of the driver and the front passenger (if the position is the left left - the feed is maximum, if the handle in the extreme position on the right - the flow is blocked).

• Left top handle adjusts air supply to.
• The bottom handle adjusts the air temperature that enters the cabin (leftmost position - cold air, Extreme right position is hot).
• The left-click-rotational, visible in the photo above, the stove fan is connected. It will increase the air supply.
  The button has 4 positions: 0 - off state, 1 - initial speed, 2 - average speed, 3 - maximum speed.

If the air temperature on the street is minus 20 degrees Celsius, the stove begins to ensure the maximum heating mode automatically.
Indicators in this case are as follows:

• +20 degrees Celsius is provided in the vehicle cabin;
• +25 degrees Celsius is provided in the passenger foot zone and driver.

Radiator

This is one of the most important details of the car heating system. Unfortunately, during the passage of a certain amount of time begins to flow.
Traces of toosol on a passenger rug or under a rug - a symptom of the heater radiator leakage. In this case, on the VAZ 21093, the heating of the salon will be absolutely broken and will have to replace the radiator.

Types of radiators

For VAZ 2109, there are several basic types of radiator.
The most popular are considered:

• Aluminum original;
• Aluminum non-original;
• Copper.

Of all this trinity, the most expensive is a copper radiator, which can also be sought in the case of which and which is largely more reliable than the rest.
Less reliable, but cheaper. The original costs about 700 Russian rubles, while unoriginal can be used for 400 rubles.
The design of both types of aluminum radiators is different:

• The plates in the original radiator are located much more dense than in the non-original version.
• The area of \u200b\u200bheat exchange in a non-original radiator is less than in the original.
• The design of the aluminum original radiator is much stronger.
• On the original radiator, the air begins to warm already at a temperature of the coolant in 60 degrees, and in non-original only at 90 degrees and higher.
• Inside the radiators of the original there are special swirls of coats, made in the form of a spiral tape. They significantly increase the efficiency of work, because the coolant does not "fly" through the radiator, and slowly circulates, efficiently by moving heat.

Replacing the radiator

Need if the old one does not function quite efficiently.
A replacement is carried out in the following way:

• The front panel is unscrewed.
• The radiator is dismantled and excreted carefully from its place.
• Install a new one.

Note. Masters self-taught recommend removing the radiator from the bottom of the instrument panel, where the lower shelf and prevents it. This shelf is scolded, and after installing a new radiator, attached on self-drawing, and in the future its removal will be easy.

On the VAZ 2109, the salon heating system is notable for exhaust ventilation, which provides suction of air from the cabin. There is this ventilation on the VAZ 2109 from behind.
In addition to providing air suction, exhaust ventilation is also carried out through the discharge, which occurs in deflectors when the vehicle is moving.

Valve

Exhaust ventilation on some versions of VAZ 2109 is endowed with valves that serve to increase the number of fresh flow air in the cabin.
In crude weather, these same valves help reduce glass fog. Basically, the VAZ 2109 models are not endowed with these valves, and most owners independently establish them on their own cars.
What needs to be done to install the valve:

• It is enough to make technological holes in the body.
• Remove the rear bumper.
• Store planting For valves.
• Insert valves.

Features of the operation of the stove and its refinement

Car owners VAZ 2109 are often concerned that over time, the stove begins to warm well. You should not say that it will be uncomfortable in such a car.
In such cases, only the modernization of the stove is able to solve the problem.

Methods of refinement

Methods set. Below are some of them.

Lever control damper

So:

• You can simply pull the bracket control cable to solve the problem. 1-2 cable turns are made on the flap control lever (the lever itself is placed on the stove body, near the gas pedal).

Note. The joints of the air ducts and the edge of the heater flap are pea rubons, which is not fully compressed.
In this regard, a seizure of several millimeters is formed, and the flap is completely closed. The method described above will help customize the lever properly.

• You can get to the control lever and in other way. On the driver's side there is a place and you need to try to reach your hand and pull the lever, be sure to enable the heater fan.
  In the process of adjustment, the left ear will be in the area of \u200b\u200bthe duct nozzle and therefore, it will be possible to hear how the sound of the outgoing air changes.

Heater crane

The reason for the inefficient operation of the heating system can be the incomplete opening of the stove crane. Such a problem, to the word, is found almost all the front-wheel drive cars of the VAZ family.

• The problem solving the valve control cable and the subsequent adjustment of the control lever to the maximum open position may be tested.

Note. In this case, it is possible that the valve will now not be fully closed. But the problem is not in this, but in the fact that after adjusting the lever, the damper can lose hermetically and begin to leak (seen in the photo).
In this case, you can advise the winding of the leakage of a cloth, which was impregnated in sealing and fixing all this with cold welding.

Air ducts

The reason for the poor quality of the heating system can be the leakage of air ducts. That air that is injected with the heater fan partially goes into the slot, and the air flow, thereby weakens and cools.

• The solution may become complete sealing and sizing compounds, which are located in the fields of air from the stove before exit.

Aerial traffic jams

In addition, the cause bad work Stoves can be aerial traffic jamsFood formed in the heater radiator.

• The solution will be the stop of the car front part on any elevation. Then you should open the heater's fully tape and click on the accelerator pedal several times.

Above, there were some ways to eliminate problems with the heating and ventilation system VAZ 2109. Instructions and tips, these experts are a chance to "cure" your car, thereby well saving on repair.
As you know, the price of technical service in a hundred is not low and if they regularly carry out them, the family budget will noticeably discrepancy. Recommended in the process independent work Use photo and video - materials.

The system of car heating in many models is arranged and works according to a similar principle. Understanding the principle of the inclusion and adjustment of the speed of the salon heater fan will be very much by the way with independent search for a malfunction (for example, if you have).

General Air Circulation Scheme

Air fence to the car interior is carried out by a fan that can be installed in the cabin or behind the engine shield. Over the electric motor is located. If necessary, heating the air flow passes through the heater radiator. The stove radiator is connected to the car cooling system, so when the engine is heated, the circulating liquid from the engine cooling system heats the stove radiator cell. Therefore, passing through honeycombs, the air flow also becomes warm.

Air dampers

Redirect airflows for temperature control is carried out by a special damper. Types of damper management:

• mechanical. The damper drive through the thrust and cables is connected directly to the switch in the cabin. In this case, the driver, moving the regulator, manually dispensing the temperature of the incoming air;
• electronic. The damper is equipped with a servo. The electric motor changes the position of the flap, receiving commands from the control unit. This scheme is applied on vehicles with climatic installations. The driver is enough to ask on board computer The desired temperature in the cabin, after which the electronic control unit, focusing on the temperature sensors, will control the air damper servo.

From the fan stove in the cabin, the channels go through which the air can be served on windshield, to your feet or through the central deflectors. Depending on the work scheme, modes can be both combined and single, when all the intake air is supplied only in one zone. Switching modes can be mechanically either using a servo and control unit. A mechanical method assumes a direct connection of air dampers with a switch on a torpedo. The shutter electric drive is allowed to control the key by pressing the key, as well as implement automatic control electronic block Air conditioning systems of the cabin.

Recycling

In recycling mode, the main air damper is closed, after which the stove fan begins to pick up the air from the cabin. Such a mode of operation allows you to block access to unpleasant odors and polluted air from the street, if you, for example, are driven by a car on a dusty gravel road.

In winter, the recirculation mode allows you to quickly warm the car's interior, since it does not go frosty, and the saloon can be passed through the heater radiator warm air. Accordingly, in summer, recycling simplifies the air conditioner cooling.

Recycle Drive Types:

How the stove fan works

The fan of the car heating system is a conventional AC motor. This can be both the simplest axial fan and the diametrical option, which is most often installed on modern cars. The internal part of the stove fan is no different from the device. conventional electric motor AC with excitation from permanent magnets.

More interest for us is the operation of an electric motor at different speeds. This feature is implemented by inclusion in an additional resistance scheme. Resistors increase resistance, which leads to a decrease in current flowing in the circuit. Consequently, the fan begins to rotate slower. The rating of the resistor determines how strong the current drop in the circuit will be. The last fan speed is straight, since the chain does not include resistance. This allows the heater fan to remain operational, even if the resistance failed.

Connection scheme

The figure shows the simplest schematic scheme Connecting the fan stove. When the plus output of the switch protected by the fuse is closed with contact H, the current proceeds to the electric motor directly, forcing it to rotate with maximum speed. When the plus contact is closed with contact V, the current flows through the resistance, which reduces the speed of rotation of the fan.

The electric motor of the heater of VAZ 2108, 21099 has already 3 fan speeds. When the plus output of the mode switch is closed by 1 contact, the circuit includes sequentially 2 resistance, so the speed of rotation of the electric motor will be minimal. When power is applied to the second contact mode switch, the current will flow through one resistor, which will match mid speed Rotation. Accordingly, 3 contact is designed to supply the power to the access of an additional resistor and corresponds to the most fast speed Rotation.

It is the principle of incorporating the electric motor of the heater on most cars. For a better understanding of the scheme, we offer watch a video.

Automated control system

In the diagram, we still see an additional resistor, that's just now all commands are transmitted to the electric filateer not directly from the knob of switching speeds, but through the control unit of the heating system (No. 3). Also block controls electromagnetic valve Recycling of the cabin and micromotor device of the damper drive. In this scheme, only one temperature sensor in the cabin is used, but in more advanced versions there are intake air temperature sensors, as well as sensors measuring at several points the temperature of the air supplied to the interior.

It is good or bad, but we live in a country with harsh climatic conditions. In the summer, everyone suffers from the heat, every year everything is hotter, in winter - a friendly frozen, spending cash on heating. Spring, autumn also do not please.

As a result, it turns out that coming out of the house and sowing into the car, come across a problem - no comfort for normal conditions For life in the cabin cars. Lucky with the ventilation system of the salon Arabs and Brazilians - I installed myself in the car air conditioning, and ride all year round. And the Eskimos are also good - enough presence in the car.

And we are from Brest to Vladivostok, both of these systems are needed, as they say, in one bottle, more precisely, in the cabin. In what money this combination comes out and how many gasoline "eats" cars year-round - a separate conversation, but one cannot be denyed - in cars, driving on the fields and forests, salon ventilation systems are needed "like air".

It would seem that you can ride without them, but the harsh truth of life quickly convince us to ride in the abpentent car of the car in winter - So guarantee all sorts of diseases from sinusitis to prostatitis, not to mention the problems with the gynecological sphere.

In the summer, it seems that everything seems simple - opened the window and enjoy the oncoming breeze, but in traffic jams, unfortunately, this breeze is not enough for everyone. Well, where there is a breeze, it does not bring anything good, except otitis, conjunctivitis and other diseases.

And you know that the short stay in the preheated oven, into which the car is becoming a summer day from the sun, even in healthy people can cause hypertensive or vascular crisis or worse than a heart attack, stroke, and many other disgusts. And considering the cost of treatment, I don't really want to pick up something from this set.

If we consider that it is not so good to service, then you should take care of your health.

Salon filter

When the interior ventilation system is running, the air passes through, and then heated or cooled, depending on the parameters set. Air is supplied for heating or cooling into the interior of the machine through a single casing.

The temperature and speed of the air flow is adjustable using special regulators on the control panel of the cabin ventilation system. Body ventilation machine occurs with a constant air flow.

The outer air falls inside the car through the air intake near the windshield, and the outside it turns out through the outlet channels, which are installed under the rear bumper.

Air volumes are adjusted by a four-speed fan. When the interior ventilation system is turned on, the heat runs heat from the heated coolant, which is in the cabin. A mixing flap allows you to adjust the necessary temperature in the cabin of the machine, "making a cocktail" hot air with a cold outdoor.

Air Conditioning - Excellent Salon Ventilation System

Summer saves - this is an excellent salon ventilation system. In cooling mode, it removes an excessive moisture and lowers the temperature in the cabin.

This happens as follows: The liquid refrigerant moves along the contour of the high pressure, when pumping in the contour low pressure The refrigerant evaporates and gas is formed. At the same time, the refrigerant is very cooled, taking heat in the cabin.

The cooled air fan penetrates the car interior. Further, passing through the capacitor, the liquid refrigerant returns heat outdoor air. Since the refrigerant constantly walks on closed contour, the car's salon is cooled constantly and the heating release can last for a very long time.

The moisture of the air mass of the cabin is removed, condensing on the evaporator of the Condichen refrigerator. As a result, we have an automatic and constant salon ventilation system that is installed and adjustable by air conditioning.
