What does climate control on a kashirka mean. Materials for replacing air conditioning with climate control

Today it is already impossible to imagine a modern car without a system climate control. This comfortable device perfectly performs its functions both in hot summer and frosty winter. The driver does not need to be distracted by adjusting the temperature inside the cabin, the programmed mechanism will do everything for him. Simply choose the temperature that best suits you. In order to evaluate how climate control works in a car in winter, it is enough to drive such a vehicle several times. Driving pleasure is guaranteed.

How it works

Modern automotive air conditioner includes the following main components and mechanisms:

• air conditioner- helps to cope with excessive high temperature and humidity;
• car stove– selection of heat is made from the warmed up cooling liquid of the engine;
• fan– provides mixing of air inside the passenger compartment;
• air duct and intake system- makes it possible to distribute air flows and direct them to the required point of the cabin;
• air intake shutters– driven by electric servo drives;
• electric oven valves- cut off the heat exchanger when there is no need for heat;
• thermal sensors- measure the air temperature at different points in the cabin;
• humidity sensor- not used in older models;
• software controller– analyzes sensor data and gives commands to turn on actuators.

Scheme of the air conditioning system

The principle of operation of climate control in a car in winter is as follows:

• the driver sets the desired temperature in the cabin, for example, 23 degrees;
• the unit is switched to the "auto" mode;
• the controller analyzes the data from the temperature sensors and compares with the task;
• if the temperature in the cabin is higher than the set one, then the air conditioner turns on (in winter this is practically impossible);
• if the temperature is lower than the set temperature, then the electric valves of the stove open, antifreeze is supplied to the radiator from the engine cooling system;
• based on the difference between the actual temperature and the set temperature, the controller gives a command to turn on the required fan speed, while taking into account the degree of heating of the coolant in the stove;
• if necessary, the "Recirculation" mode is automatically switched on;
• when the set temperature is reached, the controller reduces the blowing speed and switches the system to the maintenance mode.

Four-zone climate control

Features of operation in the winter

The climate control algorithm described above is quite general. Each manufacturer develops a climate system for specific model or series. Software controller may also be slightly different. Latest Versions electronic climate control allow the owner of the machine to independently program some of the functions of the unit. The operation of climate control in a car in winter sometimes requires intervention and switching to manual control:

• The car was on open parking and its windows were covered with ice. To start moving, it is necessary to quickly clear the viewing spaces from ice. Not all climate control firmware provides for automatic preheating glasses. There may be a situation when the program provides for such a function, but the set heating time was not enough. In this case, you have to exit the automatic mode and manually turn on the defroster. The fan speed will also be up to you. After the icing is eliminated, you can return to automatic settings.

Climate control unit

• Unlucky drivers often rely on the fact that it is warm inside the car and neglect reliable winter shoes. Inopportunely fallen snow makes you trample around the car for some time. After the vehicle is released from snowdrift the driver gets wet feet as a bonus. In such a situation, the most correct solution is to switch to manual control and direct the flow of hot air to the legs.
• You can spend quite a lot of time in long winter traffic jams caused by ice and snow. In order to avoid getting hit exhaust gases from the transport accumulated around to the car interior, use the "Recirculation" mode. Only very advanced air conditioners are equipped with an automatic analyzer of the CO level in the outside air intake.

Humidity reduction function

Almost everyone knows that the air conditioner, working for cooling, dries the air at the same time. And how the climate control in a car copes with this task in winter, not many have heard. To ensure this function, the unit is equipped with a special humidity meter. The data from this sensor is sent to the controller. At low negative temperatures, air dehumidification is usually not required; the stove also copes with moisture vapor. The situation changes at temperatures close to zero, under conditions wet snow, during thaw. The car windows begin to fog up intensely. In this situation, your air conditioning system will work as follows:

• the humidity sensor will inform the controller about the need to remove excess moisture;
• the controller will give a command to simultaneously turn on the air conditioner and the stove;
• humid air, passing through the evaporator of the air conditioner, will leave moisture particles in the form of condensate or frost on the heat exchanger cells;
• after the evaporator, the air enters the stove radiator, where it is also additionally dried.

Thus, the use of climate control prevents the windows from fogging up and ensures comfortable driving conditions in winter period.

Cabin filter

Filter

Before using climate control in a car in winter, carefully read the car's operating instructions. You will surely find recommendations for replacement in it. cabin filter. This air purification element plays very important role to operate the air conditioner. If the filter is clogged with dust, then heating and drying will be ineffective - the windows will fog up, the interior will heat up more slowly. Manufacturers offer three options for filter elements:

• paper– the easiest and cheapest way to clean;
• coal- operate much more effectively;
• antibacterial- prevent the reproduction of pathogens in the air ducts of the car's air conditioning system.

The first car with air conditioning appeared in the United States in 1940. It took 13 years for the Chrysler Imperial to install new system conditioning. Time passed, the industry developed, air conditioners became popular. Then climate control appeared, automakers began to supply vehicles with it. Of course, air conditioners from the 1940s or 1953s are no match for modern climate control systems, but in their time they were the novelty that predetermined the development of the industry.

How does air conditioning work in a car

Air conditioners installed in modern machines, have mechanical control. Their work is similar to how air is cooled in a refrigerator.

Warm air is absorbed by the refrigerant, it cools down and returns to the interior of the car again. Passing through the air conditioner, the air is dried. Because it works from crankshaft engine, using the engine power, when the air conditioner is turned on, fuel consumption increases.

Freon is used in the air cooling system, for its replacement it is worth contacting specialized centers. The system is sealed, it is a closed cycle. When you press the air conditioner button, it starts working electromagnetic clutch. The air conditioning system is mated to the pulley, this is done by the action of the pressure plate of the drive unit.

Because of the belt drive, the pulley is spinning from the crankshaft, it works constantly. Freon is compressed by the compressor, when compressed, the gas is heated and sent to the condenser. Here it is cooled by an electric fan, which constantly operates at the first speed. When in a traffic jam, he turns on the second one, starting work with great effort.

Freon cooled in the condenser, changing its aggregate form, becomes a liquid. It is sent to the receiver-drier, where it is filtered, while debris is removed from it. Through a valve that corrects the temperature, the filtered freon is sent to the evaporator. There it boils and then evaporates. Cooled fumes enter the car interior, and freon goes to a new cycle cycle.

What is climate control in a car

climate control (in English language is an abbreviation of HVAC, which means "heat supply, ventilation and air cooling") includes several systems. These include the heating system, as well as air conditioning and installed in the vehicle air filter. The car owner turns them on simultaneously or separately. Yes, in winter time it is possible to simultaneously turn on the heating system so that the windows do not fog up - air conditioning.

The climate control system responds to any changes in temperature. It cools the air, turns on the heating system if it gets cold inside the car. The system also regulates the operation of the fans.

The owner of the car chooses the parameters himself, and the climate control will monitor their observance. The electronic "brain" processes the information coming through the sensors located in the cabin, and then regulates the operation of all systems.

In winter, climate control analyzes the temperature outside the car and inside the car. Then he, taking into account the information, regulates the operation of the air dampers.

First, the flow of warm air is directed to the glass, then it is directed to the legs, seats and face of a person. Some automakers produce cars in which the driver has to adjust the operation of the climate control on their own, based on their needs. He will indicate which places in the cabin to direct warm air in the first place.

Which is better: air conditioning or climate control

To compare two systems, it is best to do so on a number of parameters.

• The air conditioner only cools the air. Climate control is responsible for ventilation, heating and cooling.
• Air conditioning control is mechanical, climate control is electronic.
• When the climate control fails, the stove, ventilation and cooling system stop working. If the air conditioner breaks, the stove will work.
• Climate control is easy to control, the driver does not need to monitor the temperature in the car, there is no need to constantly change the setting. The climate control system, reacting in time to the slightest changes in the environment, itself monitors the comfort in the cabin.
• When comparing the response speed, the climate control is in the lead. It quickly turns on additional power when needed, cooling or heating the interior. The air conditioner will have to be controlled independently by turning the control knob, increasing or decreasing the cooling of the air.
• Climate control is safer than air conditioning, because the driver is not distracted by the settings while driving, emergencies due to distraction will not occur.
• Climate control saves fuel because it turns off ventilation and heating in time when they are not needed. The air conditioner works until you turn it off.
• Climate control is configured separately for the driver's seat and for each passenger seat.

Outcome

In the confrontation between climate control and air conditioning, climate control is in the lead. It works to make passengers and the driver feel comfortable in the car. You will have to pay extra for convenience, but this pleasant option will add convenience.

Climate control is a specialized, electronic system to create and maintain acceptable humidity in the passenger compartment and temperature indicators. The ideality of the created conditions in the car interior in this case is closely related to the temperature indicators overboard. Carefully thought-out automation completely frees the driver from the need to manually configure the system.

Types of climate control

The specificity of the climate control system, equipped with a variety of sensors, gives it a chance to successfully vary the temperature regimes in different zonal compartments of the car. So, the main types of climate control systems include:

• 1-zone;
• 2-zone;
• 3-zone;
• 4-zone.

Thanks to the latest, progressive electronics, the four-zone climate-forming system allows you to create comfortable temperature conditions for both the driver of the car and his passengers.

How climate control systems work

The climate system is a piece of equipment that consists of the air conditioner itself and the program for its control. The air conditioning system is an element of the harmonious combination of the functions of ventilation, heating and air conditioning. The control system is responsible for the regulation and control of the equipment in use. It consists of a number of sensors:

• Sensor for determining the pressure of the air conditioning system;
• Sensors for determining the temperature indicators of the air inside the car and outside it;
• Sensor for determining the degree of solar radiation.

The essence of its work is the reception of sensor signals by the control unit and their transmission to a specific actuator. Based on the data obtained, the changed indicators are regulated.

How climate control works is shown in the video:

Operational features of the climate control system

The ease of operation of the climate-forming system lies in its full automation. It is enough for the driver to indicate the desired temperature indicators on the display, after which the program itself will establish the procedure for achieving the specified result.

The most optimal is the functioning of the climate system when the internal circulation of the ventilation system of the car is in the "ON" mode. In this case, the climate-forming system is always in standby mode, ready to “adjust” the temperature conditions in the passenger compartment in a timely manner. However, it is recommended that the driver perform operations to block the deflectors and select the required direction of the air flow on their own.

Recirculation of air must be taken as seriously as possible. The consequence of finding cooling in the “OFF” mode may be the formation of condensate on the evaporator, fogging of the windows and the formation of bad smell.

During the hot season, the climate control system should work as follows:

1. The driver must slightly open the doors and windows of the car and wait for the moment when the temperature indicators of the passenger compartment and environment equalize.
2. Close doors and windows, set the recirculation mode to maximum.
3. Get out of the car for a while.

When the vehicle is moving with the climate control system turned on, the ingress of air from outside should be avoided. It can affect the change in sensor performance. In any case, regardless of the time of year, the climate system contributes to an increase in fuel consumption.

Features of the control mechanism

All work of the climate control system is based on the interaction of the ECU (electronic control unit) and sensors. Acting as a think tank, the ECU decides to adjust the temperature conditions in the car. An assistant in achieving the required temperature indicators is also a device called the evaporator-heater unit. All work of the climate-forming system is exclusively automated.

Operating with a fan and dampers, the ECU is determined with the choice of the most optimal direction, temperature regime and air flow strength. So, there are the following options for the direction of air flow:

• In the area of ​​glass;
• In the area of ​​​​the legs;
• In the area of ​​​​glass and legs;
• In the area of ​​the face;
• In the area of ​​​​the legs and face.

Carrying out work on the installation of the climate control system

Installation of climate control is a rather complicated and time-consuming process, in which it is best to trust professionals. The specifics of installing the climate system, depending on the car model, the manufacturer of the climate system and its configuration, forces this procedure to be carried out in a car service despite the high price range. By saving on this service and installing the climate-forming system on your own, you can become the initiator of the breakdown of a number of critical elements.

Climate control system installation steps (may be different for various models auto):

1. Dismantling the glove compartment of the car and its center console.
2. Draining the antifreeze - dismantling the stove - the battery mount is removed.
3. Cutting a hole required for recirculation, taking into account the markings made - creating mounting holes for the evaporator and connecting them.
4. Accurately making a hole in the area of ​​\u200b\u200bthe motor shield.
5. Implementation of the replacement of the existing wiring of the cooling fan with specialized wiring of the sensors of the climate system.
6. Installation and subsequent connection of sensors such as ceiling and fan sensors.
7. Pulling the battery wire and wiring - connecting the pads - installing the heater and evaporator unit.
8. ECU connection.
9. Implementation of a preliminary control of the performance of the entire system.
10. Mounting the radiator, installing the freon line and bracket for the compressor - fixing the compressor - screwing the hoses - mounting the fan.
11. Installation of dryer and throttle.
12. Checking all working lines and the tightness of the system - filling the climate system with freon.
13. Monitoring the correctness of the data received from the sensors.

Specific care of the climate control system

Mandatory conditions for the proper operation of the climate-forming system are flushing the air conditioner radiator (at least 2 times a year) and timely refueling. By following all the rules for operating the device, you can enjoy the correct and efficient operation of the climate control system for many years.

Price of climate systems

Climate control systems are expensive. As statistics show, the average price offers of the market range from $1,000 to $15,000. Cheap models, as a rule, are characterized by limited functionality and low quality.

Pros and cons of climate control systems

Pros:

• Creation of comfortable conditions for being in the car;
• The ability to determine the temperature overboard;
• No need to manually configure the system;
• Elimination of the possibility of hypothermia and overheating.

Minuses:

• High price range;
• Increase in fuel consumption indicators;
• The probability of failure of the entire system in the presence of malfunctions in adjacent compartments.

A number of modern systems that are being developed by engineers large auto concerns, are designed to create the most comfortable conditions in the car interior - for example, to maintain the optimum air temperature. A striking example of such useful equipment is the climate control system.

Climate control: definition and purpose

This is a complex technique that includes an air conditioner, temperature and humidity sensors, a heater, an electronic control unit and a filtration system. primary goal climate system- the formation of a microclimate in the passenger compartment that is comfortable for the driver and passengers, as well as its maintenance. The following conditions are recognized as suitable for a person: temperature - from +22 to + 25 ° С, humidity - from 65 to 80%. Climate control analyzes these indicators, and then heats the air in the cabin (using the stove) or, on the contrary, reduces its temperature (thanks to the air conditioner).

Can an air conditioning system be added?

Almost in all modern cars climate control included basic equipment. Vehicles equipped with this system different types- from cars and buses to self-propelled vehicles and special equipment.

You can also install the system additionally - as a rule, many motorists refuse air conditioning in its favor. However, it should be remembered that the installation of climate control is not possible on any car, because this requires a stove of a certain configuration that would allow mounting a servo drive and laying wiring under the “torpedo”.

Differences between climate control and air conditioning

• Functional. Climate control is able to maintain a constant temperature in automatic mode. An ordinary air conditioner is designed only to cool the air, and to heat it, you need to turn on the stove. The principle of operation of the air conditioner is also different: first it takes in air, dries it, and then heats or cools it.

Besides, modern models climate systems provide adjustment that will not allow you to catch a cold. This is especially important if you often carry babies. Air conditioners do not have this capability.

• Design. Climate control is a more complex system than air conditioning. Thanks to the sensors, the unit is able to analyze parameters such as temperature and humidity, and the most advanced models can also take into account other indicators: for example, the temperature outside the car, etc.
• Control. The climate system is equipped electronic unit management. This provides a significant advantage, since the car enthusiast needs to set up the system once - stable temperature regime she will support herself. In a car not equipped with climate control, the driver will have to constantly be distracted to adjust the stove and air conditioning.

How does the system work?

Despite the complexity of the mechanism, the principle of its operation is quite simple:

• Sensors set the temperature outside the car and in its cabin.
• The fan takes in air from outside and delivers it to the passenger compartment. Subsequently, the flow is divided into 2 parts: the first goes to the stove, the second goes to the air conditioner evaporator.
• Air currents, coming out of the heat exchangers, are mixed and enter the car interior thanks to the system of deflectors and air ducts.

You can adjust the temperature by changing the position of the central and additional curtains, which are located on the climate control panel.

How to use the system?

First you need to activate the system - this is the button ON/OFF(in some car models, instead of an inscription, an image of a broken circle is applied to it). To set the desired temperature, use the buttons or the rotary knob. In most installations, the adjustment step is 0.5 degrees. The marginal difference between zones usually does not exceed 5°. If comfortable temperature set, press the key AUTO– the system will support it automatically.

Special buttons will help to adjust the air direction, each of which corresponds to a certain mode: blowing legs, windshield or head and legs. These 3 modes are considered standard, but there are additional ones:

• blowing warm air windshield, as well as the lower area of ​​\u200b\u200bthe cabin.
• Windshield blower to prevent condensation.
• Supply of air to certain parts of the body and head, or combinations thereof.
• Manual mode climate control.
• Recycling.

To take into account all the nuances of operating the unit in your car, carefully study the technical documentation.

Operation of climate control in cold weather

in winter The air conditioner is mainly used for heating outside air. Under these conditions, the stove will be enough for you.

In a situation where zero temperature is combined with high humidity and complemented by snow and rain, you will need the full potential of the system - it should be switched to automatic mode. Air conditioning will help remove excess moisture.

Varieties of climate control

• The most primitive type of system is single zone climate control. As the name implies, the equipment is able to maintain a microclimate in one zone, in which the driver and front passenger are located.
• dual zoneclimate control monitors the indicators separately for the driver and the front passenger. This is convenient because everyone has different ideas about comfortable temperature.
• Three- and four-zone equipment allows you to adjust the temperature "for yourself" as well as the rear passengers.

2-, 3- and 4-zone units are combined into one group - multi-zone climate control.

Pros and cons of the system

The benefits of climate control include:

• Creating favorable conditions for people who are in the car. With such equipment, a trip to the office or a supermarket, and a long trip to another city or even a country will be as comfortable as possible.
• The ability of the system to automatically maintain the set modes, that is, without the involvement of the driver.
• A large number of adjustments.
• Simple interface, as well as clear system management.

It is also important that the driver, who is in comfortable conditions(he does not freeze and he is not hot), he can fully concentrate on driving. This improves operational safety vehicle.

However, motorists have identified a number of shortcomings:

• The presence of climate control increases the cost of the car.
• Maintenance and repair of equipment are expensive.
• With the full use of the system, fuel consumption increases.
• In the event of a breakdown, you will not be able to repair the system yourself.

You learned the difference between an air conditioner and a modern climate system, and analyzed the pros and cons of installing equipment. If you still choose to maximum comfort, then do not forget about the care of climate control: the system must be cleaned regularly. In this case, it will please you with long uninterrupted work.

Climate control is modern system, which allows to ensure a comfortable stay of the driver in the car. Many motorists believe that climate control (CC) is the same as air conditioning, but this is fundamentally wrong. You can learn more about the device, types, as well as the rules for operating such a system from this article.

Climate control feature

What is climate control pro, how to use such a system, how to set up climate control in a car with your own hands? First, let's look at the basic concepts. The QC system is a collection of several nodes. The climate control unit is a control module, which, in fact, is the brain of the system. The main feature that the climate control pro has in the car is the ability to maintain the temperature within the set range.

The control module analyzes the temperature outside, and also takes into account how much the vehicle has warmed up from the sun's rays. This ensures the comfort of the driver and passengers in the cabin. If the ambient temperature is very low, the controller automatically activates interior heating. In addition, if the air flow that enters the car interior is too dirty, the control unit will detect this and activate the recirculation mode. In this case, the driver himself will be able to activate and set the temperature in the cabin in the range from 16 to 30 degrees (the author of the video is the PetrovskiyTV channel).

The operating system is controlled using a special regulator located on the shield, where the desired temperature range is set and regulated. The signal is sent to the control module, which gives the command to activate the climate control. The central damper of the system mixes the flows of cold and hot air, thus selecting the desired temperature. If necessary, the control unit can activate the air conditioner, with the help of which moisture and heat will be removed from the car interior.

Varieties

What are the types of QC systems:

1. single zone devices. The control of one zone systems is carried out by the driver of the vehicle. That is, it is the person who chooses the appropriate temperature regime.
2. Dual zone QC. Dual zone climate control- This is a more advanced version of the climate system. In vehicles equipped with such installations, the system automatically regulates the temperature in the area of ​​the front seats.
3. Three-zone QC - in this case, the installation operates in three zones.
4. Four-zone. In this case, each passenger can adjust the desired temperature regime.

Device

The scheme of any QC system includes many different elements, each of which performs a specific function. Moreover, than newer car, the more components and mechanisms will be included in the circuit.

QC device:

1. Control module or block. This element is considered the main one, since it is it that determines optimal parameters for the installation to work. If the block breaks, the operation of the QC will be impossible.
2. Air conditioning system.
3. Ventilation and heating.
4. Radiators (their number may vary depending on the type and model of the car).
5. A fan that brings air from the environment into the passenger compartment.
6. The air conditioner, which consists of an evaporator, a compressor, a condenser element and a receiver.

Principle of operation

What is the principle of operation and how does climate control work in a car? In addition to the control module, the operation of the system is also affected by input touch controllers and executive mechanisms. When the QC is activated, the input controllers come into operation, which measure all the necessary for normal work parameters and subsequently convert them into signals. These controllers include ambient air temperature controller, outlet temperature controller, evaporator controller. As mentioned above, KK is also equipped with special detectors that measure the degree of heating of the car body from sunlight.

It should be noted that the number of all controllers that the CC is equipped with can be different, in this case it all depends on the car model and the system itself. The outlet temperature controller can be optionally equipped with a detector installed near the driver's feet. In dual-zone installations, two controllers are used, one of which is mounted in the area of ​​\u200b\u200bthe pedals, and the second under the glove box.

There will be more detectors in three- and four-zone QCs. Each of these devices is used to provide optimal mode functioning. As mentioned above, the climate control unit is carried out by a unit that collects signals from sensors and, analyzing them, sends a pulse to the executive components.

Actuating elements include dampers, as well as a fan electric motor. These components are used to create the desired temperature range and further maintaining this temperature at a certain level in the car. The dampers start working when they are actuated by a drive, and the latter, depending on the type of AC, can be either mechanical or electrical.

Terms of use

How to use the air conditioner?

There are several points regarding use and maintenance that must be considered in order to prevent damage to the CC:

1. To set the required temperature, you need to use the regulator on the center console, after determining the range, the control module will do everything by itself.
2. If the recirculation mode is enabled, this will provide the most efficient work QC. In this case, the air conditioner will operate in standby mode, while not wasting energy. But in this case, a lot depends on your own preferences.
3. Before activating the CC, especially in the hot season, always ventilate the interior. Thanks to ventilation, you can achieve the most optimal equalization of the temperature level in the passenger compartment and outside.
4. Since the operation of any CC is based on air conditioning, this device must be periodically refueled. Refueling is carried out in accordance with technical regulations, but usually our compatriots perform this task before starting summer season. Before filling the conder, you need to make sure that there are no leaks in it.
5. Not less than important point in terms of maintenance is cleaning QC. This need, as a rule, arises in the event of an unpleasant smell of dampness in the cabin. The principle of cleaning is to introduce a probe of foam or other type of cleaner through the central air duct with further pumping of foam into it. After pumping the foam, you need to wait about 15 minutes, then start the engine and activate the QC to the maximum. In principle, the cleaning procedure can be completed on this (the author of the video is the Morning of Russia channel).

Health check

Consider the process of checking the status of QC using the example of a Toyota car:

1. First of all, the ignition is activated, to do this, turn the key to the desired position.
2. Then it is necessary to simultaneously activate the heater with the air conditioner.
3. Next, the key in the lock should be set to the ACC position.
4. Having done this, we proceed to the main stage. You need to simultaneously press the Auto buttons, as well as the button to activate the recirculation mode. After that, the key should be returned to the ON position.
5. After completing these steps, the diode lamps should start flashing on the display, after which combinations of errors will appear on it, by which the car owner must determine what exactly has failed. Combinations of errors are individual for all cars, so the decoding should be sought in the technical documentation.
