What is climate control in an air conditioner. Operational features of the climate control device

How good and simple it used to be: hot - opened the window, cold - closed the window. Intermediate options were also envisaged: a little hot, a little cool ... Not like now: only really budget cars(some of which are not even actually cars in the usual sense of the word) are not currently offered at least with air conditioning. A more pleasant option is when climate control is listed in the “weather in the house” selection box. But what is the difference between conventional air conditioning and climate control? Especially in cases where the latter has its own subparagraphs: two-zone, three-zone ... Let's figure it out.

To begin with - the most brief technical digression about the operation of the air conditioner, as a simpler and more understandable system. In short, an air conditioner is essentially the same as a home refrigerator: cold refrigerant enters the evaporators in the cabin, changing from liquid to gaseous form. In the process of transformation, it absorbs heat from the passenger compartment, giving back its “cold”. Thanks to the compressor, the gaseous mixture returns to the radiator, is cooled by air flows and returns to the liquid state. The process is repeated. In this case, the accompanying dehumidification of the air in the cabin can be considered a bonus (moisture in the air condenses on cold pipes, and then is discharged outside the car). Accordingly, the windows in the car sweat less. By the way, this is just one of effective ways fight against humidity, so usually bothering already cool autumn and still warm winter when the stove does not seem to be turned on yet. The regulation of operation is also as simple as possible: selection of the set temperature for supplying cold air and selection of the speed of operation of supplying this air to the passenger compartment - i.e. fan speed.

In this regard, it is important, of course, to follow how proper work of the entire system, as well as for its individual components: a violation of the tightness of the connections will release the refrigerant into the atmosphere and there will simply be nothing to cool, and (for example) a faulty compressor will not allow the air conditioner to be turned on as a whole. Here https://starter.ms/kompressory, if necessary, you can see the option for your car - you never know what ...

Let's summarize the intermediate result: the air conditioner in the car is essentially equal to the refrigerator, where all the operating parameters must be set manually. We are not talking about “automation” of processes in principle.

And the logical evolution of air conditioning is climate control. In essence, the only difference for the end user is that in the depths of the car there is a set of sensors that control part of the ongoing processes. We chose the required temperature in the cabin, turned on the “AUTO” mode - and the system itself will determine the intensity of the fans and the temperature of the supplied air. The simplest example: the car warmed up nicely in the parking lot, they went in and the climate system turned on the fans to the maximum in order to (logically) lower the temperature as quickly as possible. As it approaches the required setting, the intensity of the airflow decreases down to the minimum "turns", offering only pleasant coolness without the annoying noise of running fans. Depending on the “tricks” of the system, sensors can include not only simple temperature cabin sensors, but external sensors that complement the “cooling pattern” with parameters of street temperature, humidity, degree of interior illumination, vehicle speed, and so on.

Incredible in comparison with the often crudely mechanical adjustments of a conventional air conditioner, the progress of climate control is the ability to adjust the temperature to within a degree (for more simple models) and half a degree (for more complex systems), so choosing what you want is not so difficult.

As noted above, the "climate" has its own sub-items, including the number of serviced "zones" - that is, the possibility of individual temperature and airflow settings for different parts of the cabin:

• one zone - adjustment only for the cabin as a whole, but mainly for the driver;
• two zones - separate temperature and air flow control for the driver and front passenger
• 3 zones or more - inclusion in the "distribution" of the back row / rows of passengers

Well, from a purely technical difference between air conditioning and climate control only in the presence of the above-mentioned sensors for the latter, as well as the possibilities for the same "climate" for individual fine-tuning. Compressor, refrigerant, radiator, etc. remain essentially the same. Of course, except for the really fancy systems in premium cars ...

The close relationship of both systems also has logical “thin spots” of their work:

1. When clogged cabin filter(which, unfortunately, not many people know, is the same “consumable” as washer oil) the system starts to work worse, appears bad smell in the cabin.
2. Air ducts can also accumulate pathogenic bacteria over time (isn't it a breeding ground where it's warm, dark and humid?), so it's worth cleaning them out at least periodically. To do this, either special compressors are used that supply very hot steam, or special smoke "checkers" that drive the disinfectant through all channels. Of course, in both cases it is not recommended to breathe these compounds.
3. Radiator located in engine compartment car, is also subject to pollution: a cocktail of midges, foliage, fluff from trees eventually form a shield that is insurmountable for incoming air on the front surface of the radiator - which logically leads to correct operation even air conditioning, even climate control. Unfortunately, the design features of some cars do not allow you to simply “blow through” the radiator - for cleaning you have to completely remove the front bumper.

What's in the dry matter? Air conditioning differs from climate control in fact by the greater “independence” of the latter, which has a positive effect on both general condition driver, and on traffic safety (no need to be distracted by setting up work). Yes, and during the subsequent resale, the presence of a climate system “on board” will become the same big plus for the car as alloy wheels or leather interior. The main thing is to properly serve everything.

The comfortable interior of the car is probably one of the main factors by which motorists choose their car. But even the most luxury saloon, the most comfortable chairs and excellent ergonomics cannot bring pleasure if it is hot inside or, conversely, too cold. For this reason, engineers designed and equipped cars with air conditioning and systems that would summer time cooled the air and warmed it up in winter. Now motorists are increasingly facing or climate control. What is the difference?

Story

But in the beginning there were only air conditioners. The first car, which was equipped with air conditioning, was developed in 1940. Naturally, it was still very far from the solutions that are used today. Modern air conditioners began to appear only after 13 years. However, at that time it was considered a real technical breakthrough. And even more - the installation of air conditioning in the Chrysler Imperial in 1953 paid off - a whole industry of automobile air conditioners was launched. Thanks to this, more functional climate systems subsequently appeared.

Today you can find cars in various configurations- somewhere there is air conditioning, and somewhere - the climate system. Let's try to figure out how climate control differs from air conditioning, and also learn about the design of climate equipment.

Definition of concepts: air conditioning and climate control

If you try to briefly talk about the difference between air conditioning and the climate system, then the first thing to say is that these are completely different terms that many people often confuse and do not know if there are differences between climate control and air conditioning in a car. And this confusion is not surprising - both solutions have similarities and solve similar problems. These systems are designed to support in the cabin comfortable temperature. But I must say that air conditioners appeared much earlier. So let's start with them.

car air conditioner

Almost every one of us has a split system hanging on the wall at home. However, the air conditioner differs significantly from household equipment. The device is powered not by electricity, but by rotation crankshaft through a belt drive. Air conditioners are designed only to cool the air in the cabin. IN summer period to adjust the intensity of the operation of this device, it is necessary to change the fan speed. The faster the fan rotates, the sooner the air becomes comfortable. If it is necessary to heat the air, then the stove starts, and warm air accelerates through the cabin with the help of the same fan. It should also be noted that when the air conditioner is running, it first takes in air, then dries it, and only then will the flow heat up or cool down.

They control air conditioners in modern cars using mechanical or digital systems management. It all depends on the make and model of a particular car.

Climate control

Now consider the difference between climate control and air conditioning. The first complex is a kind of system that automatically supports a certain and constant temperature. The temperature regime is set using various electronic systems. Due to electronics and sensors, the efficiency of the air conditioner, heater, and ventilation system is regulated.

Climate control device

So we have climate control. How is it different from an air conditioner? At least the fact that the climate system consists of several blocks. This is a control element that controls humidity and temperature using sensors. There are even some models of climate control equipment, which take into account other parameters. This is solar radiation, temperature overboard, but often this is not necessary. In addition to the control unit, there are no other major differences. But it is thanks to the electronic unit that the ride becomes comfortable. Many people love climate control. How is it different from an air conditioner? Yes, because there is no need to be distracted from control by adjusting stoves and air conditioners.

Also, in addition to the fact that with the help of electronics, the climate system automatically regulates temperature and humidity, it can also independently move the dampers of the air ducts and choose such directions so that the driver or passengers do not catch a cold. Air conditioners do not have this feature. This is the difference between air conditioning and climate control. What's better? Definitely the second option. He won't be able to catch a cold and get sick.

The need for an electronic control unit

The control unit receives information that comes from sensors inside and outside the car. Next, it analyzes the desired environment and, based on this data, calculates what needs to be done in order to satisfy the driver. Thanks to a comprehensive analysis, climate control is much better than conditioner. At the same time, it is also possible to reduce fuel consumption - the amount of energy consumed also depends on how much you have to cool or heat. If you correctly set up the air conditioning system and the stove, and the intensity of this equipment is minimal, then the consumption can be reduced quite significantly.

How to operate air conditioning and climate control

The first is controlled only manually. On the center console or dashboard there are special controls with a "snowflake", which is also indicated by the "A / C" icon. You have to control only with the help of these buttons.

But what if the car has climate control? How is it different from an air conditioner? Firstly, complex management. However, it cannot be said that the management process is very complicated. On modern cars with climate control there is a button - Auto. This button starts the climate system. After the control unit starts up, the system will begin to analyze information from the sensors and make a decision - to cool or heat the air in the cabin. Naturally, it cannot be said that the system works that way on all cars. But in in general terms everything converges.

Types of climate control systems

Depending on the specifications systems it can create different temperature in several areas of the car. The sensors already familiar to us help her with this. There are one-, two-, three- and four-zone solutions.

For example, we have dual-zone climate control. How is it different from an air conditioner? It can create two separate microclimates in different parts of the cabin at the same time. So, usually one is near the driver, and the other is near the passenger.

The operation of the climate system in the winter season

Depending on the model and brand of the car, the type of equipment, and on the climate system, the algorithm may be different. Most often, these differences can be noticed only in winter - for example, in the process of warming up the car in the morning, the control unit will independently move the deflectors first to the windows, then the air stream will smoothly fall to the feet. At the end, the heated air will go towards the driver's face. In this state, driving is much more comfortable.

Knowing the principle of operation and the basic mechanisms, one must also remember that in each machine these algorithms can be individual. The thing is that in some systems, warming up can be performed differently. In addition, some complexes can be configured, while others do not allow you to make any settings. And even more - separate systems automatically turn off the air conditioner if the windows are fogged up from the inside.

How not to get sick under the car air conditioner

Climate control and air conditioning in the cabin is not a guarantee that the cabin will be as comfortable as possible. It is necessary to be able to use these systems correctly so that the temperature is comfortable, but nothing more. If it is too low, and it is very hot outside, there is a huge chance of catching a cold. To prevent this from happening, it is necessary to abandon low temperature regimes. In order not to get sick, the temperature should be set 5 degrees lower than outside. IN long trips it can be reduced, but this is done gradually every 2 hours. Then the temperature regime will be as comfortable as possible, and the risk of a cold will be minimized. In winter, climate control is adjusted so that the cabin is not hot. Going out into the street, there is a serious risk of getting sick. Often, climate systems are set to 22-26 degrees in winter.

Which is better: climate control or air conditioning for Definitely climate, because the driver will not constantly adjust the temperature and be distracted from the road.

About the disadvantages

Obviously, the climate system is more convenient to use. With a one-time setup, it immediately provides maximum level comfort for many months. However, is everything really good? Automation, with all the advantages, has disadvantages that can seriously affect the choice, and a person will choose a regular air conditioner. The first minus is the price. It is much higher if the car is equipped with climate control. But when people want more comfort for themselves, then the manufacturer can capitalize on it. The second drawback is low reliability and low maintainability. Climate equipment consists of many electronic devices. Let's take, for example, the electronic unit, which a conventional air conditioner does not have - it sometimes fails, and the efficiency of the entire complex depends on its behavior.

Verdict

Climate control or air conditioning - which is better? If we consider in terms of convenience, definitely the climate. But if reliability and a limited budget are your priority, it is better to give preference to air conditioning.

The automotive industry is developing at a rapid pace - new enterprises are being created, companies are re-equipping old plants, new concepts are appearing. There are several reasons for this “behavior” of the industry, but progress and technologies introduced into modern machines play a special role.

Fundamental concepts

To begin with, we will analyze the devices in a little more detail in order to have an idea about the subjects being studied.

An air conditioner is a device that cools the air inside a car. The crankshaft belt drive is used as a power source. Hence the trivial conclusion - the loss of engine power affects the performance of the system, the level of fuel consumption increases (later we will analyze why this happens).

Air conditioner control panel

But the shortcomings are compensated by an acceptable temperature balance.

Climate control is a closed system that combines heating components, air conditioning, measuring instruments, sensors and a separate ECU (electronic control unit). Automatically (after pressing the "Auto" button), data is received from sensors located in the cabin and outside it, and the mini-computer processes the incoming signals.

More advanced samples also analyze the degree of illumination inner space and even humidity!

Control Panel

The Chrysler Imperial was the first car to have air conditioning. The epic event took place in 1953.

The principle of operation of the air conditioner

Changing the temperature in the car is possible thanks to the refrigerant - freon. Over time, its number decreases, which forces the driver to contact the specialized service station.

Consider the functioning of a closed system in a step-by-step form:

1. Pressing the button activates (joins) the device with a pulley, which moves with the help of a crankshaft belt drive.
2. In the compressor, freon becomes gaseous, it is compressed, which increases the temperature of the "refrigerator".
3. The path lies through the radiator, where a separate fan (first gear is used) cools the warm gas-air mixture.
4. The aggregate state changes to liquid in the condenser, then the receiver-drier filters the composition.
5. Freon enters the evaporator, where it releases steam due to the difference temperature indicators, the built-in fan directs air streams to salon.
6. The refrigerant is used cyclically.

The scheme of the air conditioner

The efficiency of the air conditioner directly depends on the movement of the car; in a traffic jam, the second gear is automatically switched on for the built-in fans. This contributes to greater consumption of gasoline or diesel.

How climate control works

The electronic control unit works with the stove and air conditioner, regulates the fan speed, the direction of air flow.

The accuracy and versatility of the "box" is achieved due to the n-th number measuring instruments and sensors. They are located around the perimeter of the car, inside the cabin. Why such innovations?

The system analyzes the temperature inside and outside the machine. Electronic devices send information to the "command center", where the received data is processed.

Built-in algorithms compare the given parameters with the available ones, the ECU issues commands to various devices.

Location of air ducts

Climate control reduces fuel consumption, as the operation of components is optimized for the minimum allowable values.

Advantages and disadvantages of air conditioning

For ease of perception, let's break down the strong and weak sides component on several lists.

Drivers love:

• ability to cool the air high temperature behind the windshield;
• increasing the level of attentiveness and reaction due to comfortable conditions in the cabin;
• car air conditioner fight bad smell(tobacco, alcohol);
• air dehumidification under adverse weather conditions(prevents fogging of windows).

Flaws:

• reduction in the power of the driving unit;
• increased temperature under the hood ( free space gets smaller)
• frequent maintenance constituent parts devices, their rapid wear;
• increased fuel consumption.

The disadvantages are offset by the obvious cheapness of installing an analogue of the cooling system.

Advantages and disadvantages of climate control

Electronic equipment and technical innovations not without strengths and weaknesses.

Motorists are happy:

• comfortable driving conditions for "iron horses";
• accurate determination of the outside temperature;
• automatic operation of the system, which does not distract from the analysis of the roadway;
• inability to catch a cold due to incorrect temperature regime.

Few prepared:

• to the high cost of components and the system as a whole;
• to costly repairs, incapacity of the system due to the breakdown of one device.

The initial stage of repair work

There are more advanced systems on the market that allow you to adjust the microclimate for the driver-front passenger connection (two-zone) and rear seats(three- or four-zone).

Differences between climate control and air conditioning

Consider the main differences between the two systems:

• Control. An automated system is opposed to manually setting the mode of operation. The driver is distracted from studying the road, which is fraught with the appearance of an emergency.

Climate Control Panel

• Comfort level. The task of the computer is to adjust the zoning of air cooling, taking into account the justification for using air ducts. In technical terms, the opponent is clearly losing.
• The complexity of the system. A multi-level system is devoid of the disadvantages inherent in individual components. Climate control combines components into a single organism, an increase in their number improves the quality of the ECU.
• Price policy. An automated system is not cheap, but it pays off a hundredfold in terms of comfort and fuel economy. Drivers who make a choice based on price will prefer a cheaper component.

It is better to buy a used car with air conditioning - the savings are obvious. In the case of a sale, the situation is reversed.

Climate control is characterized increased level comfort for the sake of affordability and affordability. Air conditioning is more attractive to consumers middle category prosperity.

Air conditioning and climate control are two systems for cooling air flow inside the car, which have their own differences. Many motorists today do not understand what is the difference between these two devices. This material will help you understand this issue.

[ Hide ]

Air conditioning: good or bad?

What is the difference between air conditioning and climate control? First of all, let's look at the merits of the first. A car air conditioner is one of several types of systems for cooling the air flow of a car interior. If the home conder is powered from the mains, then in the case of a car, the device is powered from the crankshaft of the motor. This means that the air conditioning system cools the air well precisely thanks to power unit. That is, the conder, in fact, uses part of the power from the internal combustion engine.

Accordingly, in any modern car when you activate the conder, you can notice how the engine power drops while driving. Accordingly, the power unit has to apply more forces to normal operation resulting in an increase in fuel consumption. But it should be noted that this method air flow ventilation is and undeniable merits, in particular, this comfortable ride by car in the summer heat.

How does an air conditioner work?

The principle of operation of the air conditioning system is somewhat similar to the operation of a freezer in any refrigerator. Of course there is a big difference in respect of internal structure and devices, but in general, these units are similar. Moreover, in different Vehicle and different cooling systems are used, but this, as practice shows, does not affect the principle of operation. The main role in the operation of the conder is played by a looped system through which consumable- antifreeze, freon - and which is hermetically sealed.

From time to time, the consumable must be changed, experts recommend that this procedure be carried out using special equipment. But in principle, it is quite possible to complete this task on our own - we have already written about this, detailed instructions you can find it on this link.

How do air conditioners work? After the button for turning on the device was pressed in the passenger compartment, a very difficult process. First of all, it gets to work electromagnetic clutch. At the first stage, the pressure roller drive mechanism docks with the system pulley.

It must be taken into account that the shaft is always functioning and it rotates from the crankshaft due to the use of a belt drive. Then the compressor comes into operation, designed to compress the consumable material. The compressed antifreeze heats up and enters the condenser, where it begins to cool thanks to a functioning electric fan.

The fan itself always operates at a reduced power, but if the car is in a traffic jam or it is parked in a parking lot, the fan may switch to a higher power on its own. This is done to cool the unit, but the process itself does not end at this stage. When the consumable cools in the condenser, it begins to change its aggregate form and turns from a gaseous state to a liquid one. Then the resulting liquid begins to enter the dryer device, where it is filtered from dust and other debris (the author of the video is CrazyRussianShow).

Further, the purified consumable enters the evaporator through a special valve that regulates the temperature. Here, freon boils and, accordingly, evaporates, and the resulting fumes are cooled, after which they enter directly into the interior of the vehicle. As for freon, it enters the beginning of the cycle, as a result of which the process is repeated again.

Climate control: what kind of device?

To understand how an air conditioner can differ from a climate system, let's analyze the device of the latter. There is one thing in climate control important advantage- this system allows not only to cool the air flow, but also to heat it. In addition, such a device differs from a conder in that it is equipped with "brains", that is, a control unit. The control unit analyzes the data that comes from various controllers and regulators located in the car. In fact, the motorist can independently choose the required temperature regime, which will be maintained inside the car, and the unit will regulate the temperature in accordance with the specified parameters.

What is the difference between air conditioning and climate control? System climate control in the car allows you to automatically adjust the temperature in order to ensure the comfort of the motorist. One of the important advantages of such a device is precisely the adjustment - the system will be able to independently select the desired mode in accordance with the season. After all, climate control analyzes the temperature not only inside the car, but also on the street.

As a result, based on the information received, it automatically adjusts the position air dampers. Initially, in frost, the system regulator transfers the air flow to the vehicle windows so that the ice melts on them. Further, the seats and legs of the driver and passengers are heated, after which the air flow is directed to the face of the motorist. But it should be noted that not all vehicles are equipped with such a “smart” system, although many automakers today offer motorists to independently regulate heating. That is, everything here lies in the financial capabilities of the car buyer.

climate control

To understand what is better - climate control or air conditioning - let's look at the issue of managing these systems, let's start with the conder. It is not so difficult to manage such a device, almost any motorist can cope with such a task, since all settings are set manually. The control panel itself is quite simple - it contains a key for adjusting the compressor device, a temperature regulator with dampers. Also on the panel is a fan speed switch along with a regulator for the distribution of air flow in the cabin (the author of the video is L0RlC).

The disadvantage of such a device is the need to monitor the instrument panel and adjust the parameters, which can be problematic to do while driving. There are several types of conders themselves, in which case they are divided among themselves according to the type of control. It can be carried out both with the help of buttons and levers, as well as on the liquid crystal display.

As for climate control, to set the required temperature, the driver only needs to select the appropriate parameter on the display. The rest of the actions the control unit will perform for the driver. best effect from cooling or heating will be achieved by setting the system to operate in recirculation mode. Read more about the principle of operation and management of the system here.

What to choose: climate control or air conditioning?

What are the major differences between these two systems? Of course, the only one, but fundamental difference is the presence of a control unit in the case of air conditioner. As mentioned earlier, the control unit will do everything for the driver himself. That is, thanks to its use, the driver will not be distracted from the road and expose required parameters. Of course, cars equipped with a climate control system always cost an order of magnitude higher, unlike cars with Conders.

Moreover, the latter may be from the 90s of release, while cars with climate control began to appear on sale much later. As for the conversion of one device to another, replacing the air conditioner with climate control today is a fairly common practice among our motorists. Converting the Conder to climate control is not so easy, but in the end the driver gets a more comfortable installation for operation.

Sorry, there are currently no surveys available.

Video “How to install climate control instead of a conder?”

How do-it-yourself replacement car air conditioner on the climate control system - see the video below (the author of the video is Maxim Kovalenko).

Comfortable conditions are provided in the car interior special system controlling air humidity and temperature. It is known to all drivers as climate control, which very accurately reflects its functions and purpose. Majority modern machines equipped with such systems. different levels difficulties. Information about the availability of climate control can be found in the technical documentation of the car.

The first device to provide a comfortable microclimate in the car was a stove. Part of the thermal energy generated by it was used for heating. Now this device is considered primitive and not capable of creating comfortable conditions, especially in hot weather. In this article we will talk about the system that came to replace him. In other words, you will learn what climate control is in a car.

Definition

Complex designs of modern systems help them solve a wide range of problems. Let's try to understand the purpose of climate control.

The technical documentation says that the system provides comfortable conditions for passengers and the driver. The most favorable temperature range for a person is 22-25 ° C with a humidity of 65-80%. Climate control monitors these parameters and keeps them constant.

The temperature regime is regulated by an air conditioner and a stove. But with humidity, the situation is more complicated, since water vapor condenses on the windows of the car. This causes inconvenience and makes it difficult for the driver to see. Good climate control dries the air by forcing it through the air conditioner's evaporator. Due to this, water settles in the form of dew on the walls of the heat exchanger. And lowering the humidity prevents the windows from fogging up.

Now most vehicles are equipped with this device (from cars to trucks). It is also put on self-propelled mechanisms and special equipment.

Now you know what climate control is in a car. But to complete the picture, it is necessary to consider a few more important points.

How car climate control works

With the help of sensors, this device monitors the air temperature outside and inside the car. The flow from the outside is forced into the passenger compartment by a fan, divided into 2 parts: one passes through the air conditioner evaporator, and the second through the stove. After the heat exchangers, the mixed air enters the passenger compartment through a network of deflectors and box ducts.

The parameters are adjusted by changing the position of the shutters (central and additional). They are called temperature control dampers. Rotation of the dampers is carried out by electric servomotors, which reduce or increase the cross section of the channels. Everything described above is controlled through the climate control unit.

The regulator on the panel of this device allows you to set the desired temperature, for example 24 °C. These data will be sent to the processor, which, in accordance with the programmed algorithm and information received from the sensors, will control the operation of the system. Since indoor and outdoor parameters are constantly changing, they are monitored in real time.

Components

The development and installation of climate control on the machine is carried out in the process of its assembly at the manufacturer's plant. To perform the functions assigned to the device in its design, there are a number of components:

• air conditioner;
• control Panel;
• CPU;
• damper position temperature sensor;
• heater;
• blower fan;
• system of deflectors and air ducts;
• valve guide block.

Each element of the system has its own function.

The fan creates pressure. In recirculation mode, air is taken in by the system from both inside and outside.

The damper block is mounted in one housing with the air conditioner evaporator and the stove radiator. This design allows you to bring the parameters of the airspace in accordance with the established values.

The system of deflectors and air ducts distributes flows throughout the car interior in accordance with a specific program. Control is carried out using a processor that receives data from the panel from switches, regulators and sensors.

The operation of climate control in a car directly depends on the state of its control program and components.

Additional Modes

In addition to the basic functions for creating a comfortable microclimate, the device can have a number of additional modes:

• Blowing the lower part of the cabin and windshield warm air.
• Manual control.
• Windshield blower to prevent condensation. To do this, the air is dried, and the fan runs at full power.
• Air supply to various parts of the body: legs, arms, face separately or in certain combinations.
• recycling.

The latter mode is needed for accelerated cooling or heating of the cabin, as well as for driving in traffic jams. IN last situation the air outside is heavily polluted, and the car's climate control system simply shuts off its supply to the passenger compartment. For these purposes, the device provides a sensor, the working element of which consists of tin oxide. Its resistance varies depending on the level of concentration of harmful substances.

Application Specifics

Manufacturers develop climate control for a line of cars or some specific model. They differ in device, degree of complexity and control algorithm.

Inexpensive units have a low degree of automation and rather roughly regulate air exchange. Very often, when the engine is cold, an unheated stream is fed into the passenger compartment.

In advanced setups, these things don't happen, as they control a lot of different parameters. In addition to other functions, modern systems can not only monitor air quality, but also use filters if necessary. The latter use carbon and paper cartridges that trap suspended dust particles and gaseous substances harmful to humans.

IN modern systems air conditioning, the air temperature is adjusted between 16 °C and 30 °C. To avoid hypothermia, do not set very low values. For a comfortable stay of the driver in the cabin, the temperature sensor should show a difference (between the cabin and the street) of only 5-7 ° C. To speed up the operation of the device, you can slightly open the windows. Then the conditioned air will displace the cold or heat in their cabin much faster.

Dual zone climate control

Each person has an individual perception of temperature. That is, the same value for one passenger can be normal, and for another - uncomfortable. In this case, automakers came up with dual zone climate control when the driver can set the optimum temperature for himself and passengers.

We list the advantages of dual-zone climate control:

• The driver and each passenger sets the most comfortable microclimate for themselves.
• The system very accurately fulfills the programmed algorithm.
• Due to the influence of external and internal factors, fogging of windows is almost impossible in such machines.

Differences from the air conditioner

Readers who do not know well what climate control is in a car may have a question: “Why complicate the system so much? After all, it is quite possible to confine oneself to air conditioning in summer, and a stove in winter.

In the past it was, but there is one important point. Both systems can provide an optimal interior climate only if the outside and internal conditions in the car will be unchanged. For a moving object, which is a car, this is simply unrealistic. The pressure and temperature of the air change along with the direction and speed of movement.

The main difference between air conditioning and climate control is the presence of a control system that monitors all parameters and regulates them without outside participation. It turns out that the air conditioner is one of the components of the installation, which performs the function of reducing humidity and cooling.

Winter climate control

At low temperatures climatic equipment Most of the machines work on heating the outside air. In such conditions, the humidity is low, so the stove will be quite enough. And turning off the air conditioner will not affect the efficiency of the climate control.

Everything is much more complicated when the temperature is at zero with rain and snow or high humidity. In this case, the windows may fog up and Windshield. But the climate control unit will easily solve this problem by transferring the system to auto mode. And to remove excess moisture from the outside air, the system uses an air conditioner.
