What modes and functions does the air conditioner have? Did you know that when the air conditioner is in ventilation mode, no fresh air comes from outside?

When choosing an air conditioner for your home, we most often pay attention to its energy consumption and basic capabilities. Other functions of the air conditioner, such as ventilation, air dehumidification, air filtration and disinfection, remain beyond our attention. But manufacturers are making more and more efforts to introduce new developments and useful engineering ideas into their devices that can make our lives much more comfortable.

Let's look at the main operating modes of air conditioners and the opportunities they provide to users.

Cooling and heating

Cooling has always been and remains the main purpose of any air conditioner. It occurs through the use of a physical process in which the refrigerant, passing from a liquid to a gaseous state, absorbs heat from the environment. This leads to cooling of the air flow entering the room (accompanied by a drying effect due to the removal of moisture from the air). It is necessary to calculate the power of an air conditioner for cooling as follows: for every 8-10 square meters of area, 1 kW of power is required for normal operation of the device.

The “warm” version of the air conditioner (with the heat pump function) allows you to produce 300-400% more heat compared to the electricity consumed for this. In this regard, its use in the spring-autumn period is energetically feasible, and the modes justify their presence.

However, in winter, when the temperature drops significantly below zero, compressor oil and freon in air conditioners change their properties. This may lead to rapid failure of the device due to operation in unsuitable conditions. The solution to the problem is the use of a special “winter kit” (which serves for additional heating of the entire system), which allows you to expand the range of “operating” temperatures to -30 C. However, in addition to converting the air conditioner into a heater, you will receive a device that shamelessly “eats” electricity (from - for low efficiency) and your money.

There is a separate class of air conditioners equipped with a heating element. They also use a lot of electricity and are not cost effective (compared to other types of heaters).

Ventilation

This air conditioner mode (fan) uses only the fan in the indoor unit, which draws in air from outside without heating or cooling it. The use of this function is especially important if the room is heated using a central heating system.

It is possible to turn off the supply of outdoor air, turning the air conditioner into a “mixer” of air masses in the room, where the lower and upper layers are heated with different intensities (warm air collects closer to the ceiling, and colder air below).

More technically advanced models have the ability to adjust the fan speed, so you can set different ventilation intensities.

Dry mode

This mode is suitable for over-humidified rooms; it uses a physical phenomenon in which moisture from warm air falls on a cold surface (condensation). The process of air drying also occurs during normal cooling, but not so intensely.

In addition, when the “dry” mode is activated, the room temperature practically does not change, and the compressor turns on only when it deviates 1 degree above normal (or half a degree below). The drying time lasts 10 minutes, after which there is a pause of 5.5 minutes and a two-minute activation of the normal ventilation mode. Upon completion of all stages, the cycle provided by the “dry” program is repeated again.

Automatic mode selection

This function allows the air conditioner to independently select the most optimal operating modes. The device’s automation itself determines how the user’s instructions can be achieved in the best possible way (this is achieved by combining ventilation, heating or cooling modes, replacing each other as needed). The system can independently start the air drying process if this helps achieve the required temperature.

Comfortable sleep function

Activating this mode reduces the fan speed in the external unit to a minimum, due to which the device becomes silent and does not interfere with sleep. In addition, the air conditioner begins to closely monitor the temperature and gradually increases or decreases it if necessary (if it deviates from the specified “comfort” zone).

The “sleep” mode allows you to significantly save energy: the device will stop working after a specified period of time.

Timer

With this function, the air conditioner will be able to adjust the temperature in advance, before your arrival, or stop working after a certain period of time (specified using the remote control).

“Defrosting” the heat exchanger

During operation of the device, the electronics of the split system constantly measures the temperature of the refrigerant contained in the circuit of the outdoor unit. When the air conditioner uses heating mode, the refrigerant accumulates cold (“removed” from the air in the room), which inevitably leads to its freezing.

When the sensors detect a drop in the temperature of the outdoor unit circuit below -6 degrees, the first defrost starts. It usually takes 10 to 12 minutes to complete, after which the heating of the circuit stops and the refrigerant again acquires the ability to accumulate cold.

The presence of such a function will be useful when operating air conditioners in the cold season.

Air purification and filtration

Modern air conditioners are equipped with multi-stage filters that can prevent both large dust particles and harmful microorganisms that are invisible to the eye from entering the room. The filter system has three levels of purification. The first is represented by a fine metal grill (for rough air purification), the second is an electrostatic filter that “attracts” microbes and plant pollen. The final cleaning step removes tobacco smoke particles and other sources of unpleasant odors from the stream.

Panasonic has developed a special catechin filter that can not only absorb dust, smoke particles and pollen, but also deactivate bacteria and viruses that fall on it. Catechin disrupts the ability of viruses to attach to healthy cells in the body by coating microscopic “spikes” on the surface of harmful agents.

Air conditioners have become indispensable household appliances designed to maintain human comfort. But due to the many different buttons, sometimes, especially for beginners, it is difficult to select and find the appropriate air conditioner mode.

Using this device is not as difficult as it might seem at the very beginning. As a rule, the buttons and their designations are the same on all remote controls, and if you learn and remember them, you can easily use different models in the future.

The remote control is a candy bar with control buttons and a display that shows the selected mode. At the very end there is a special LED with infrared rays. Thanks to this diode, when directing the device to an air conditioning device, it is possible to remotely control household appliances. When you constantly press the button with your finger, the signal is sent to the air conditioner all the time, and the battery charge is wasted. But in the quiet state of the remote control, the battery is not active, which helps to economically consume electrical energy.

Remote control with a classic set of buttons

Symbols on the air conditioner remote control

Let's look at the main symbols on the control device:

The dry function, located in the air conditioner, dehumidifies the air in the apartment. This button is very helpful during rainy periods, in the fall or spring before turning on the heating, when the humidity in the room is high.
The TRV button means the operation of the thermostatic valve. In other words, using this function you can adjust the cooling operation.
The fan icon means either the air flow intensity mode. By pressing this button again, you can change the operating speed to the required one.
The heat function on any air conditioner literally translates as heating. You can turn on the heating of the room thanks to warm air flows. The heating mode is indicated by a schematic drawing of the sun on the air conditioner.
The dehumidification mode is the same as the dry mode in the air conditioner, only it is called differently and has a designation in the form of a drop.
The cool button performs the opposite function of heating. Thanks to this button, you can turn on the room cooling mode. This is especially good on hot summer days, when the heat makes staying in a city apartment unbearable. This button is indicated by a snowflake.
The TURBO function means increased airflow. By turning it on, you can force the fan to supply increased air flow at high speed. Thus, the room is artificially ventilated without opening windows. And it will take much less time.

TURBO button

The Swing function helps the air to be distributed evenly throughout the apartment. This happens thanks to the special movement of the dampers.
Ifeel mode is designed to determine an individual comfortable temperature. Due to the fact that users often do not know what temperature in the room will be most comfortable for them, there is a thoughtless waste of electricity. And in this case, the I feel digger comes to the rescue. The technology is highly accurate: if for some reason the temperature in the apartment is below the required degree, the household appliance set to this mode begins to warm the air, automatically turning on the heat mode. And, conversely, when the temperature rises, the device immediately turns on air cooling. Thanks to this function, the room temperature will be maintained as comfortable as possible for your stay.
Hi or H1 - the designation of these characters appears on the screen during failures as an error. When these combinations appear on the display, you should know that for some reason the device has entered the defrost mode. In order to eliminate the error, simply turn off the remote control, wait a while and turn it on again. After this, you can set the desired mode.
Pre def is also an error code that is often found in the operation of air conditioners. It means that contact with the temperature sensor is temporarily lost. This happens due to various failures in the electronic system or problems with electricity. In order to restore the operation of the device, you just need to wait until contact with the temperature sensor is resumed.
On timer / Off timer – setting will help set the device to automatic mode. It can be configured to turn off or turn on the desired mode at a specific specified time. This function is very convenient at night or when the owners of the apartment are away.

On/off timer button

Buttons for turning on and off a household appliance are necessary in order to turn the equipment on or off if necessary.
The cancel or CANCEL button helps the user to cancel a mode set by mistake.
Using the CLOCK button, you can set the time, which is very convenient for automatic mode, on/off timer, and simply using this device as a clock.
The LOCK function helps you lock all buttons on the remote control. This function helps out when there are children or pets in the family, and they can accidentally press and thereby reset all settings.
If the remote control has a backlight function, the LED button may be useful. It is needed for automatic backlighting of the remote control. Helps well in the dark.

What to do if the air conditioner does not follow the remote control commands

If the device does not respond to the remote control, you should:

make sure that the power supply system is working;
check the integrity of the case, screen, buttons;
make sure that the remote control emits infrared rays by taking a photograph, otherwise you will need to purchase a new remote control;
check the electrical network in the room to eliminate the cause of power fluctuations;
check the batteries for functionality.

To ensure that the remote control is not lost and is not subject to mechanical stress, shock, or pressure, you must purchase a special mount for it. It must be installed in a place that is accessible for use, handy and convenient.

The air conditioner remote control is an important component of this household electrical appliance. Without it, the air conditioner can only be started in automatic mode. But if for some reason the remote control is lost or broken and cannot be restored, you can purchase a universal one, suitable for all models and manufacturers.

Universal air conditioner remote control

An inverter air conditioner is a device whose operation is independently controlled by a compressor. When the maximum temperature is reached, such an air conditioner does not turn off, but reduces the degrees to maintain a constant comfortable temperature.

If you take a little time and understand the symbols of the buttons on the air conditioner remote control, you will find that using this device is not so difficult. Moreover, only a few main buttons stand out, the rest are used quite rarely.

I welcome everyone to my website “Air Conditioner”! Today I will tell you about the most incomprehensible mode in air conditioners - the “Fan” ventilation mode. This option is a basic one (present in almost all devices) and performs the function of ventilating the room. In this case, “split” creates an air flow in the room without an influx of oxygen, i.e. works like a traditional fan. Only some luxury models have the possibility of additionally introducing fresh air from the street (read more about this option).

How does the ventilation mode work and why is it needed?

The word fan means fan. After enabling this option, the device uses the so-called “shaft” (aka fan, aka drum with blades), located . Air is taken from the room, filtered and returned to the room. At the same time, layers of air of different temperatures are mixed and the entire room (apartment) has a uniform “degree”. This is convenient when, for example, the bathrooms are cooler than the living rooms (or vice versa).

This option is also relevant when, for example, a person is sick - a flow of air at room temperature can refresh him. A cold stream can only do harm. If you have small children, this function can also be a life saver. Knowing what the ventilation mode in air conditioners means, it is easier to figure out how and when to use it. The mode is turned on in the following cases:

when the air in the room is stagnant, you feel that the air next to the radiators is hot, but the heat (or cold, depending on your needs) does not reach the corridors. Cold air collected near the floor, and warmer air near the ceiling; for human comfort, it is better to equalize the temperature;
There is an unpleasant odor or dampness in the room - this can be eliminated by turning on the shaft. In this case, the air is forced through existing filters (carbon, catechin, plasma, bactericidal and others);
when the room has the optimal temperature and you just want to be under the flow of air (neither cold nor hot);
There are sick people or small children in the room for whom cold air is contraindicated, and a flow of room temperature will not harm.

Don't confuse ventilation with ventilation!

Ventilation involves the flow of fresh air from the street. But With traditional air conditioners, air from the street does not come in at all! Air
taken straight from the room. At the same time, the room temperature remains the same. This “FAN” VENTILATION mode is found in almost all modern air conditioners.

The most “advanced” models have special devices capable of taking air from the street, i.e. carry out VENTILATION. The outside air in them undergoes thorough filtration, after which it enters the room. Such devices are very expensive and extremely rare.

Do not confuse the “fan” mode and the “fan” speed control buttons

The fan mode on the air conditioner does not perform the functions of heating or cooling the room. It simply creates air flow like a fan. This same fan has several rotation speeds. Therefore, on air conditioners it is necessary to distinguish:

The rotation speed button does not turn on the ventilation mode itself!

How to turn on ventilation mode

Ventilation in air conditioners is activated using the remote control. The inclusion algorithm is quite simple:

Since the ventilation mode in traditional air conditioners does not supply fresh air from the street, the use of this function does not exclude the banal ventilation of the room. Now you understand what ventilation means in air conditioners. I wish everyone good luck! Leave comments if the article was helpful!

The modes installed in the air conditioner determine the capabilities and “talents” of this climate control equipment prescribed by the manufacturer. Each model has a set of basic (general) settings for this type of device, but there are also additional options. The modes of any air conditioner are aimed at creating a favorable atmosphere in the house.

Any control is carried out using a remote control, with the exception of window models that have a push-button control panel. However, some of the indicated commands require translation into Russian. For user convenience, graphic icons are shown next to the buttons on the remote control.

The main operating modes of the air conditioner are present in every standard device. Among them are the following:

cool (translated as “cooling”) – indicated by a snowflake;
heat (for heating) with a sun icon;
dry mode (drying mode in any air conditioner) with the image of a drop;
fan (ventilation) with a fan icon;
sleep (night mode) with an asterisk designation;
timer with a picture of a clock;
swing – the meaning is to change the direction of the curtains;
lock – lock the remote control from children;
LED – illumination of the remote control for working with it in the evening and at night.

Cooling

This is the main mission of any air conditioning device. The air conditioner mode is implemented as follows: the refrigerant poured into the device gradually turns into gas, taking heat from the room. This cools the air entering the room.

The following formula will help you correctly calculate the air conditioning power of the purchased device: for one kilowatt the area is from 8 to 10 square meters.

Subject to these conditions, the device will provide optimal cooling in the apartment. Important tip

: when this function is launched, the temperature of the split system is set to approximately 16-18 degrees. If it is not enough, connect a fan. The temperature can vary within 0.5 degrees (higher and lower).

When the outside temperature is below zero, it is important to observe the following nuances:
reduce the power of the device from time to time;
Keep in mind that changing modes takes longer.

It is best not to run this function in winter.

Heating

Many air conditioners can operate in heating mode, which is best launch in the off-season when the heating has not yet started. However, in winter, using this feature is undesirable - it will contribute to a decrease in the performance of the device.

In autumn and spring, in heat mode, 3-4 times more heat is released compared to the electricity consumed. But in the winter season, negative temperatures change the properties of freon and compression oil - which is why the device may even fail. Of course, you can purchase a special low-temperature (winter) kit or initially buy a model with a heating element for heating, but along with their use, your electricity bills will also increase.

Why is dehumidification necessary?

Thanks to this function of the air conditioner, excess moisture is removed from the room. Drying makes it easier to cope with heat and prevents the formation of mold. As a result, stuffiness disappears and it becomes easier to breathe.

The dehumidifier operates as follows:

the air conditioner dries the air for the first 10 minutes;
the device does not work for the next 5 minutes;
then increased ventilation occurs for 2 minutes.

It is very important that there are no additional open sources of moisture in the room - for example, a swimming pool. Here, air drying capabilities will not help; the use of other specialized equipment is necessary.

The device operates in cycles: from air drying to cooling. As soon as the required temperature has been established in the room, the device begins to dehumidify the air again.

Increased airflow

The ventilation mode in any air conditioner is an indicator of the blowing speed. Air flows are distributed throughout the room, without cooling or heating it.

In modern models, the fan is adjustable - for this there is additional TURBO mode. When it is turned on, air currents begin to rush around the room at greater speed. And if you turn off the air intake from outside, then when ventilating, the device will mix different air layers that have different degrees of heating (the air at the top will be warmer, and the air at the floor will remain cooler).

Silent night settings

Another name is night mode: it provides for a reduced noise level at night. In fact the fan just starts rotate at a slower speed, it turns out almost silently. But the required temperature remains unchanged, fluctuations are possible within one to two degrees.

Another name for the night mode is Quiet, comfortable sleep. It is also characterized by reduced energy consumption.

Timer

Another must-have function that will allow you to set the temperature before the user arrives home. It also shuts down the split system after the required amount of time has passed.

Swing

This feature helps uniform distribution of air volumes throughout the room. By the way, the dampers can be fixed in any one position. And for a more clear picture of what is happening with the equipment, the corresponding movements of the blinds are displayed on the remote control screen.

Special abilities

They are not implemented in every model. However, many of them turn out to be very interesting and useful when tested.

How to select the required function

After the information received, all that remains is to find out how to choose this or that function. It's simple:

select the corresponding button on the remote control;
if it is not there, then you can select the current mode using MODE, flipping through until we decide on what we need;
the current temperature is set using the plus and minus buttons;
The user will not feel the specified action immediately, but after about 5 minutes.

1. Air conditioner function "Sleep mode" Provides a comfortable temperature reduction during sleep. This function lowers the set temperature during the sleep timer program. The air conditioner fan speed is reduced to the required minimum, which significantly reduces the noise level during operation of the indoor unit. When this mode is turned on, the temperature decreases by 2°C and is maintained at this level throughout the entire period of time set on the timer. After the time set by the timer has expired, the air conditioner turns off.

The “Sleep mode” air conditioner function is present in almost all models of modern air conditioners and allows you to significantly save energy.

2. Air conditioner function "Swing" designed for uniform flow and better mixing of warm room air and cooled air coming from the air conditioner. This effect is achieved by self-oscillation of the air conditioner blinds (up and down) when the additional “Swing” function is turned on.
An additional function of the air conditioner "Air Flow Direction" allows you to fix the air dampers in the required position.
These air conditioner functions are activated on the control panel using the same keys. As a rule, these buttons on the remote control are marked with an explanatory picture (icon).

The “Swing” and “Air Flow Direction” air flow control functions of the air conditioner are present in almost all models of modern air conditioners.

3. Air conditioner function "On/Off timer" designed for delayed switching on/off of the air conditioner. This air conditioner function allows you to turn on the split system while the owner is away from the house. This is quite convenient, since by the time you arrive home, the room will have already cooled (heated) to the set temperature at the appointed time. Most often, the air conditioner function “On/Off Timer” has a timer with a range of 24 hours, but there are models with a 12-hour timer. It is quite rare to find air conditioner models that have two timers (separately for turning on and off).

The additional air conditioner function “On/Off Timer” is present in almost all models of modern air conditioners.

4. Air conditioner function "Turbo mode" ("Jet Cool", "Powerful", "Turbo") necessary to speed up the cooling of the room. This air conditioner function will be very useful if for some reason the room was not cooled in advance, but there is a need to cool it as soon as possible. The “Turbo mode” function allows you to increase the performance of the air conditioner by 10-20% and, as a result, reduce the cooling time of the room. In this (accelerated) mode, the air conditioner can operate for no more than half an hour.

It should be noted that in inverter air conditioners, the “Turbo mode” function is turned on automatically when the split system is turned on.

5. Air conditioner function "I Feel" is used when there is one person in the room or a small group is concentrated locally in one place. The specificity of the additional function of the “I Feel” air conditioner is that in this case the temperature is measured and maintained precisely for the place where the remote control is located, and in standard mode the temperature is measured in the indoor unit of the air conditioner.

Please note that when the additional function of the air conditioner “I Feel” is turned on, the temperature near the indoor unit will be lower than that set on the control panel. In this case, the direction of the air flow does not change.

6. Air conditioner function “infrared presence sensor” (“Smart Eye”, “Intelligent Eye”) An innovative additional function that allows the split system to register the presence of people or pets in the room using an infrared motion sensor. If movement is detected in the room, the split system operates in the normal, established mode. But if there is no movement in the room for a certain period of time, which indicates that there are no people in the room, the air conditioner goes into economical mode. In this mode, the temperature is maintained with a certain deviation of ± 2°C.

The additional function “infrared presence sensor” makes it possible to save up to 30% of energy, but is not present in all models.

7. GSM air conditioner function allows you to control the air conditioner remotely (remotely), which will be very useful for people with unpredictable schedules. This additional function allows you to control the split system using a mobile phone, by transmitting remote commands generated in an SMS message.
Currently, the GSM control function is used in “elite” and “VIP” class models.

When developing modern air conditioners, one of the most important areas of design thought is to reduce the noise level during operation of climate control equipment. In order to reduce the noise level of the air conditioner, the designers had to increase the overall dimensions of the indoor unit in order to accommodate a fan with an increased diameter. Modern air conditioners during operation produce a noise level not exceeding 28 dB.
