It is rare to see a car in which the temperature is regulated using open windows or stoves. Most automakers produce models where regular system air conditioning provided standard equipment. As additional option they offer a climate controller automatic type. Let's figure out how justified the additional costs for such equipment are, and what are the main features of the two systems that provide comfortable temperature inside the car.
Is there a difference or how does a climate control system differ from an air conditioner in technical terms?
Many car owners do not see the difference between these concepts at all. This is primarily due to the similar functional purpose. climate systems– maintaining a pleasant microclimate in the cabin. In fact, the differences are quite significant. For example, the car air conditioner appeared much earlier than the controllers that automatically regulate temperature regime.
If you choose climate control or air conditioning in a car, then you should consider their functional features:
- The air conditioner helps a lot in the heat, but its work constantly needs to be adjusted.
- The climate controller works in a clearly defined temperature mode, just press the "Auto" button, and you can forget about the settings.
Unfortunately, not all cars are able to boast of the ideal operation of the climate control system, but this is a topic for a separate discussion. But one thing can be said for sure - not needed in the cabin.
Features of the automatic system
To answer the question, what is the difference between climate control and air conditioning, it is enough to understand simple thing. Roughly speaking, this is the same air conditioner, in the design of which sensors, electric drives, a bus and a control unit are embedded. The latter is usually located on the center console and performs a number of important functions:
- Analysis of humidity, interior and exterior temperatures using sensors.
- Adjustment of fan speed, damper position and compressor capacity.
- Indication of operating modes and parameters.
The driver has the ability to turn off the auto mode of a running system and independently adjust its performance at its discretion. You can’t do this with an ordinary car air conditioner, there is no electronic version, and you have to manipulate the switches on the front panel.
Features of the air conditioning system
Unlike automated climatic equipment, the adjustment panel consists, as a rule, of mechanical switches. Manipulators for directing air flows and temperature controllers are connected by cables to the corresponding dampers of the stove and air conditioner unit. A similar method of organizing recycling can still be found in budget models.
There are two more ways to implement aggregation management:
- Some manufacturers use a vacuum drive, but it is also not capable of providing auto mode and is controlled manually.
- Electric adjustments include buttons for turning on the compressor and adjusting the speed of the fan unit.
- Electric recirculation dampers, where the fan motor is equipped with a sliding contact instead of a cable.
Automatic climate control or air conditioning in a car - which is better?
All dampers of the climate controller are equipped with electric actuators that are connected to the control unit. The recirculation damper actuator has two positions: open and closed. Shutters responsible for the direction of air flow and temperature have a more complex algorithm of operation, any opening angle is allowed. 
Anyone who is interested in the difference between cabin climate control and air conditioning will be interested to know one important detail. In the first system, a semiconductor transistor is responsible for the speed of rotation of the fan blades, and in the second, a simple resistor. The technological solution using a transistor implements a wide range of control options:
- In manual mode, there are several fixed steps, their number depends on the design of the rotary knob on the panel.
- When the automatic mode is on, the fan speed is controlled by an electronic unit with a set of intermediate speed parameters.
Compared to the car air conditioner, additional sensors are involved in climate control. The main ones are considered to be temperature meters in the cabin and solar radiation. Their readings are actively used in the operation of the control unit, which, in turn, promptly corrects the direction of air flows and their temperature.
The central climate control unit controls executive mechanisms through a separate bus. But in order to connect the compressor, he has to send a request to the engine module. This procedure also applies to manual control.
Total Inspection
Motorists who have not yet decided which is better, climate control or air conditioning in the car, should take into account one more important detail. The “think tank” of the climate center focuses on many indicators:
- Coolant temperature is taken into account. ICE fluids, for which the controller is used in the stove unit or in the engine. This allows you to optimally assess the thermal resources and distribute them correctly.
- Multi-zone climate systems include not only numerous sensors located throughout the cabin, but also additional block heater/air conditioner for rear passengers.
Summary
Given the number of modes and adjustment methods, the climate control unit can be compared with electronics injection motor. All this is explained by the need to promptly set up heating and air conditioning systems so as not to distract the driver while driving.
An intelligent climate system has a number of advantages over traditional air conditioning:
- Automatic stabilization set temperature inside the car.
- The selective direction of the air flow ensures safety for the health of passengers.
- Not only temperature parameters are adjusted, but also humidity.
- Possibility of inclusion additional features, for example, air recirculation without its external intake or the inclusion of aromatization.
Air conditioning and climate control are two systems for cooling the air flow in 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 the conder is activated, 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 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 vehicles apply different systems cooling, 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 crankshaft through 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 collect desired mode according to 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 far from all are equipped with such a “smart” system. vehicles, 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- this is the presence of a control unit in the case of an air conditioning system. 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 to replace a car air conditioner with a climate control system with your own hands - see the video below (the author of the video is Maxim Kovalenko).
Row modern systems 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. The main purpose of the climate system is to create a microclimate in the passenger compartment that is comfortable for the driver and passengers, as well as to maintain it. 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?
In almost all modern cars, climate control is included in the list 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 with an electronic control unit. This gives a significant advantage, since the motorist needs to set up the system once - it will maintain a stable temperature regime on its own. 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 the comfort temperature is 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 the legs, windshield or head and legs. These 3 modes are considered standard, but there are additional ones:
- Warm air blow 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 air conditioner It 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 is complemented by snow and rain, you will need the full potential of the system - it should be converted to auto 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 increases the safety level of the vehicle operation.
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.
We are accustomed to the fact that the car has long ceased to be a luxury, as well as just a means of transportation. We want to see in private car not just four wheels and a gearbox, but also some convenience and comfort. One of the components of this comfort is maintaining an optimally acceptable temperature in the car interior. Once upon a time, the only way to somehow cool the car was to have an air conditioner in it, but now most manufacturers have switched to a more advanced climate control system. Both devices are widely used not only in cars, but also to maintain the temperature in the room. The difference between climate control and air conditioning is significant, and not only in price.
Definitions
Climate control refers to the air conditioning systems of a car or a room, and in English it is abbreviated as HVAC. This abbreviation stands for Heating, Ventilation & AirConditioning, that is, heat supply, ventilation and air cooling. Therefore, climate control has several components: heating system, air conditioning, air filter. At the same time, control systems can work both separately and simultaneously. For example, in winter, both the heating system and the air conditioner can work in the car at the same time to prevent the windows from fogging up.
Air conditioner also refers to the air conditioning systems of a car or a room, but it has a rather narrow scope of activity - to cool the air.
Principle of operation
The essence of climate control is to respond to changes in temperature inside the car or room, and regulate it using the available systems: cooling, ventilation and heating. With the help of special sensors, which are located around the entire perimeter of the object, information about the temperature state enters the “brain” of the device, that is, the climate control is controlled by electronics. If the climate control breaks down, not only the cooling system, but also the heating system fails at the same time. The work of climate control implies an increase in fuel consumption when it comes to a car.
The air conditioner has mechanical control. The principle of operation is somewhat reminiscent of a refrigerator, that is, there is a refrigerant that absorbs warm air, cools it and redirects it back into the room or into the car interior. The air is also dried out. A significant disadvantage is that when the air conditioner is running in the car, fuel consumption increases significantly.
Findings site
- Climate control is responsible for cooling the air, its ventilation, and also for heat supply. The air conditioner is designed to cool the air.
- The electronics are responsible for the operation of the climate control, and the mechanics are responsible for the operation of the air conditioner.
- If the climate control fails, then you simultaneously lose the cooling system, and the stove, and ventilation, while if the air conditioner breaks down, the stove continues to work.
Understand the differences between car air conditioning and climate control.
Whether the car will be in demand among potential buyers is also affected by the comfort of being in its cabin. And whatever luxury saloon, no matter what materials are used in its decoration, but if the temperature inside it is too low in winter or too high in the summer heat, then the car will no longer deliver pleasure. Automakers are well aware of this, and therefore equip modern cars climate systems and air conditioning and ventilation systems.
The first car equipped with an air conditioning system was released back in 1953. It was a Chrysler Imperial. And although this first car air conditioner does not even come close to any comparison even with the simplest modern car air conditioners, at that time it was just an innovative breakthrough. Since then, automakers have seriously begun to think about installing air conditioners in their cars.
Differences between air conditioning and climate control
First of all, it is worth noting that the difference between these two concepts is very significant. Many people confuse these things because of their similar main function - maintaining a comfortable temperature for people inside the car. You should know that the air conditioner was invented and began to be installed on cars much earlier than climate control. Much later, a system appeared that controls the climate in the cabin, and it contains much more: the air conditioner itself, and the stove, and other devices for controlling the temperature in the cabin. And some cars (like Infiniti) even have a built-in air ionizer!
car air conditioner
The car air conditioner is intended only for cooling the air space inside the car. Having a special temperature sensor overboard, the air conditioner will not turn on if the ambient temperature drops below a certain value. After turning on the air conditioner, the intensity of its operation is controlled by the fan speed. The cabin cools more with increasing speed. On a note - clogged filter salon may not miss enough cooled air, and many motorists rush to a specialized service, although it is enough to simply change the cabin filter.
If it is necessary to heat the passenger compartment, the heat comes from car stove and accelerated by the same fan.
It must be added that before air is supplied (whether warm or cold) to the passenger compartment with the air conditioner running, it is preliminarily dried before cooling or heating.
The air conditioner is controlled either by a manual mechanical switch or by buttons on the panel. It depends on your car model.
Climate control system
Climate control differs from a conventional air conditioner in that it can maintain a constant set temperature in the car interior, which is set using the control system, which is also responsible for the intensity of the air conditioner, stove and fan.
Climate control has in its design several built-in systems interconnected using electronic block control, which, with the help of sensors, monitors the interior temperature and humidity, and outdoor temperature and humidity, respectively. Some climate systems even control solar radiation outside, but this is rather a useless option.
In addition to the presence of an electronic control unit (ECU), there are no other differences between the two concepts described above, but the ECU makes it more comfortable to be in the passenger compartment of a car equipped with climate control. All you need from the driver is to set a comfortable temperature and that's it. Controlling the operation of the stove, air conditioner and fan speed, switching air flows between air ducts (to the feet, to the face, to the glass, etc.) will no longer distract you from the road (the ECU will do all this for you), which means Such a system will further increase the safety of movement to some extent.
The principle of operation of the computer
Special sensors installed inside the car and outside it read the data and transmit it to the computer. He, in turn, analyzes the information and compares the received data with the temperature set by the driver. Further, the ECU, seeing the difference between the desired and the actual, makes a calculation necessary action and will either add or reduce the temperature of the stove, or increase or decrease the intensity of the airflow, and direct the air into a certain deflector. At the same time, not surprisingly, fuel consumption is reduced, because the operation of the fan and stove will be at acceptable minimum values, which will require less electricity generated by the generator, which in turn leads to less fuel consumption.

Air Conditioning and Climate Controls
Conventional car air conditioning is controlled only manually. Usually on the instrument panel there is a button with the image of a snowflake or with the symbols "A / C". The air conditioning compressor is switched on by pressing these buttons. Climate control is usually turned on with the "Auto" button. After pressing it, the temperature in the car's interior is analyzed, and the ECU starts certain actions to bring the readings up to set by the driver. The indicators are set either by turning the knob, or by using the "+" and "-" buttons on the climate control panel.
Peculiarities winter work climate control
On various models cars are equipped with different climate control systems, which have their own characteristics winter operation. For example, in winter, during engine warm-up, some systems do not feed into the cabin cold air, although they can force it to blow the central glass, and as the engine warms up, they begin to gently feed it into the passenger compartment. Some systems during winter movement try to supply warm air to the driver's face with sufficient heating of the passenger compartment, believing that it will be more comfortable for him to move around.
Some systems, for example, do not supply air to Windshield with the air conditioner turned off, assuming that it will fog up this way. In general, each system is individual.
How to Avoid Air Conditioning Colds
But in addition to comfort, the air conditioning system, or rather its improper use, can be harmful to health. If you set a very low temperature in the cabin, which will contrast strongly with the temperature environment, then you can easily catch a cold. In order not to harm your health, you should not set the temperature in the cabin below more than five degrees compared to the street. The thing is that with short movements, your body will be in a constant contrast temperature difference, and this the right way catch cold. If the trip is a long one, and it is not planned to get out of the car for a long time, then the temperature can be lowered to a greater value, but it must be lowered gradually.
In winter, the same can be said about the heat in the cabin, because when you get out of the car in the cold, you can also catch a cold. In a car with climate control in the frosty season, it is desirable to set the temperature at around 22-23 degrees. This, by the way, is another undeniable plus of climate control. After all, in a car with conventional stove you have to turn it on first. full power, and as the cabin warms up, gradually reduce it to a comfortable state, distracting from the road.
How to make the most of climate control
For maximum effective work climate control, it is necessary to monitor the condition of its radiator. It is necessary to carry out regular cleaning to remove dirt, in which pathogenic microbes usually settle, which can also settle in the human respiratory system, passing through the air ducts of the car. Such cleaning does not require much effort, but the effect of it will be significant. Also on sale is special formulations(smoke "checkers") for cleaning ventilation systems. Its meaning is that all windows and doors are closed, the air conditioner is turned on for maximum power with air intake from the passenger compartment and the checker opens. The smoke from it is sucked into the ventilation system, killing pathogenic bacteria there.
It is possible to achieve the most efficient operation of air conditioning systems in summer only with tight closed windows and hatch. After that, turn on the recirculation mode so as not to make the car constantly waste energy on cooling hot outside air. But it is worth at least once every half an hour to turn on the air intake from the street in order to receive a fresh portion of oxygen.
If you got into a car that is hot from standing in the heat for a long time, then it’s worth it, on the contrary, to use only outside air so as not to force the car to cool the hot interior air. After the car and the air inside it have cooled down, you can turn on the recirculation mode.
Some tricks
First, it is worth using the air conditioner compressor correctly. It is worth knowing that it works most efficiently when high revs engine. This means that in order to quickly lower the temperature in the passenger compartment of your car to a comfortable one, you should switch and drive for a while. low gear to increase compressor performance.
In wet weather, it is worth turning on the air conditioner, even if it is not hot outside. This will dry out the interior and prevent the windows from fogging up. For quick drying, the air conditioner should be turned on in tandem with the stove.
