I welcome everyone to my Air Conditioner website! Today I will tell you about the most incomprehensible mode in air conditioners - the “Fan” ventilation mode. This option refers to the basic one (present in almost all devices) and performs the function of ventilation of the room. In this case, the “split” creates an air flow in the room without oxygen supply, i.e. works like a traditional fan. Only in some luxury models there is the possibility of additional mixing of fresh air from the street (read more about this option).
How the ventilation mode works and what it is for
The word fan in translation means a fan. After enabling this option, the device uses the so-called “shaft” (it is also a fan, it is also a drum with blades), located. Air is taken from the room, filtered and re-introduced into the room. At the same time, air layers of different temperature are mixed and the whole room (apartment) has a uniform “degree”. This is convenient when, for example, it is cooler in bathrooms than in living rooms (or vice versa).
The option is also relevant when, for example, a person is sick - a stream of air at room temperature can refresh him. A cold stream can only do harm. In the presence of small children, this function can also save. 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 stagnates in the room, it is felt that the air is hot next to the batteries, and heat (or cold, depending on needs) does not reach the corridors. Cold air has gathered near the floor, and warmer near the ceiling; for the comfort of a person, it is better to equalize the temperature;
- there is an unpleasant smell or dampness in the room - it is eliminated by turning on the shaft. In this case, the air is driven through the existing filters (carbon, catechin, plasma, bactericidal and others);
- when the room has the optimum temperature and you just want to be under the flow of air (not cold and not hot);
- there are sick people or small children in the room, to whom cold air is contraindicated, and the flow of room temperature will not harm.
Do not confuse ventilation and ventilation!
Ventilation means the influx of fresh air from the street. But traditional air conditioners do not get air from the street! Air 
taken directly from the room. At the same time, the same temperature is maintained in the room. This mode of VENTILATION "FAN" is available in almost all modern air conditioners.
The most "advanced" models have special devices that can take air from the street, i.e. carry out VENTILATION. Outside air in them is subjected to 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 just creates airflow like a fan. This same fan has several speeds of rotation. Therefore, on air conditioners it is necessary to distinguish between:
The rotation speed button does not turn on the ventilation mode itself!
How to turn on ventilation mode
Ventilation in air conditioners is turned on 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 airing of the room. Now you understand what ventilation in air conditioners means. I wish you all good luck! Leave comments if the article was helpful!
Using the air conditioner, you can hear that the windows must be closed at the same time. At the same time, some continue to open windows, while arguing that in this way it is possible to ventilate and cool the room faster. It is worth understanding the problem and understanding whether it is worth turning on the air conditioner with the windows wide open?
Increase in air volume
Experts say that with open windows, the volume of air in the room increases significantly. The air conditioner, which at this time cools the air in the room to a certain temperature, is forced to spend more energy and time on cooling the constantly increasing volume of air mass. At the same time, already cooled air will go out the open window, warm air, in turn, will again enter the room. Such air exchange negatively affects the operation of the air conditioner, which constantly increases its power in order to maintain the set temperature. You should also not ignore the unjustified consumption of electricity, which goes to the enhanced operation of the air conditioner, since, in turn, this will lead to unjustified financial expenses.
Rapid clogging of filters
Another reason why it is not recommended to use the air conditioner with the windows open. Air conditioners have filters that tend to get clogged from time to time. Manufacturers recommend cleaning the filters from time to time to avoid problems and interruptions in the operation of the cooling unit. An air conditioner running with the windows open runs the risk of clogging the filters much faster. Which can damage the device.
The risk of catching a cold doubles
Almost everyone knows that under the air conditioner you can easily catch a cold, and therefore they try to stay away from the device at the time of its operation. Also, with open windows, they try not to sit in a draft, as you can imperceptibly harm your health. With the windows open and the air conditioner turned on at the same time, the risk of catching a cold from drafts doubles, so those who practice the simultaneous ventilation and cooling often suffer from colds and complications caused by respiratory diseases. Experts recommend cooling the room with air conditioners only if necessary, since, in addition to a cold, allergic complications can also be earned.
Often people wonder whether it is worth installing air conditioning in an apartment, office and other premises. Therefore, I propose to talk about the various misconceptions associated with the purchase and operation of the air conditioner. After analyzing the main questions related to the problem posed, we will compile a list of the most frequently asked ones and try to give answers to them.
- Is the air conditioner a distributor of various harmful microorganisms?
- Does using conditioner cause allergies?
- Does air conditioning damage your hearing?
- Does the air conditioner dry the air?
- Does the air conditioner supply air from outside?
- Can the air conditioner be used to heat rooms?
- Does an air conditioner make the air "dead"?
- Do I need to ventilate the room when the air conditioner is on?
- Will the air conditioner fit into the interior of the room?
- How safe is it to use an air conditioner in a child's room?
- Should I install a more powerful air conditioner?
When using the air conditioner, you can catch a cold only if it is used incorrectly. Many people, trying to create significant coolness in the room in the summer heat, set the temperature on the air conditioner to be very different from the temperature outside. When entering from the street into such a room, a temperature difference is created due to its difference in the room and in the environment. This may cause you to feel unwell. To avoid such problems, air conditioner manufacturers recommend not creating a difference of more than 5 ⁰С between the temperature in the street and in the room. Or, when entering from the street, slowly lower the temperature, allowing the human body to get used to it.
Also, naturally, the cause of a cold can be the direct direction of the flow of cool air on a person. In the same way, you can catch a cold and sitting under an open window. To avoid this problem, operate the air conditioner correctly. Modern models have comfortable modes in which cool air is distributed in the room in the right way. The dampers of air conditioners make automatic oscillations up and down, during which there is a uniform dispersion of the cooled air inside the room.
There is also a mode in which the blinds direct the flow of cool air along the ceiling, and since the cold air always goes down, the room is gradually cooled. And, of course, in order not to catch a cold, observe the temperature regime. Manufacturers advise not to set the temperature above 22 ⁰С. Thus, you will create a comfortable environment and eliminate the risk of colds.
2. Does the air conditioner spread various harmful microorganisms?
A warm and humid environment is most favorable for the reproduction of a variety of bacteria. In modern models of air conditioners, condensate is at a temperature of about zero degrees, which prevents the growth of pathogenic bacteria. In addition, air conditioners are equipped with special filters that help destroy pests to our health and purify the air in the room. And, of course, it is recommended to clean the filters from various contaminants in time and replace them. As recommended by manufacturers, this cleaning procedure should be done about once a month. Some modern models are equipped with self-cleaning filters. They can be cleaned and replaced less frequently.
3.Does the use of the conditioner cause allergies?
As for allergic reactions, they are possible only if the filters of your air conditioners are dirty. Coarse filters are recoverable, so keep an eye on them. Clean them at least once a month. And since fine filters cannot be restored, just replace them every 2 to 3 months. And the problem with allergies will be solved.
4. Does the operation of the air conditioner damage hearing?
Basically, the noise level created by the air conditioner is not more than 35 dB, and for some models it is about 21 - 24 dB. Taking into account the permissible noise level in residential premises, the value of which is 50 dB during the day and 40 dB at night, the performance of modern air conditioners is significantly low. So you don't have to worry about your hearing. For especially sensitive people, you can use silent air conditioners for apartments.
5. Does the air conditioner dry the air?
According to the standards, the humidity in the room should be 30 - 60%. Yes, air conditioners dry the air a little, but at the same time, the value of the humidity parameter will be 30 - 40%, which is the norm. Do not forget that high humidity promotes mold growth, which can affect your well-being. Therefore, additional drying of the air will even benefit.
6. Does the air conditioner supply air from outside?
Many people think that the air conditioner has two tubes through which air enters and leaves the room. In fact, the pipes are designed to circulate refrigerant through them. This is a special substance that takes heat from the room and carries it outside. And if there is less heat, the air in the room will, of course, be cooler. To be more precise, the air conditioner does not take or supply air from outside. He just drives it indoors. Cooling occurs due to the passage of room air through the heat exchanger of the indoor unit of the air conditioner. Thus, the cooled air is returned to the room again. This is how an indoor air conditioner works.
Freon is absolutely safe in the operation of the air conditioner. This is the gas that powers the air conditioner. It can only be harmful if you inhale it fully, which can only happen with a serious leak. And such a situation can arise, mainly, in case of an accident and on large powerful systems. Therefore, if you entrust the installation of the air conditioner to professionals, this situation will not arise.
8.Can the air conditioner be used for space heating?
Despite the fact that in many models there is such an additional function of the air conditioner as space heating, it is less efficient than conventional heaters. Therefore, in the cold season, it is still not recommended to overload the air conditioner, since such long-term loads adversely affect the operation of the device.
9. Does the air conditioner make the air "dead"?
In the air of any room there are small particles called aerons. They are very beneficial for human health. It is widely believed that air conditioner filters trap these particles, and because of this, the air in the room becomes “dead”. This is a false opinion, because filters are able to catch small debris, but not as small as aerons that are useful to our body. You don't have to worry about the state of the air.
10. Is it necessary to ventilate the room when the air conditioner is on?
Do not confuse air conditioning with ventilation. Air does not leave the room and does not enter it. The air already in the room is circulated and passed through the refrigerant for cooling. Despite the fact that there are air conditioners with a mixture of fresh air, it is still recommended to occasionally ventilate the room in order to throw the accumulated carbon dioxide out into the street.
11. Will the air conditioner fit into the interior of the room?
In office premises, most often, such a problem does not arise, since usually the design has a “European-style renovation” style. If we talk about living quarters, then, if necessary, you can perform hidden installation of the air conditioner. But in many cases, air conditioning against the background of other household appliances fits perfectly into the interior.
12. How harmless is the use of an air conditioner in a child's room?
If you want to take care of your baby's peaceful sleep, you can install so-called silent air conditioners, the noise level of which ranges from 20 to 25 dB. This is comparable to the noise level in a library room. It is also necessary, in addition to the desired temperature, that the air in the children's room is clean. In such cases, models with an air purification function are used. Devices with hypoallergenic and deodorizing filters are also suitable.
13. Is it worth installing a more powerful air conditioner?
If you want to install an air conditioner in a small room, then you should not install a heavy-duty unit. Excessive air flow can lead to colds. If the room is large, then the air conditioner with a small capacity will suffer from overheating. Typically, 2 kW air conditioner models need about 0.7 kW, and consume less energy than many household electrical appliances.
Good luck with your air conditioner!
Greetings to all visitors to the Conditioner site! Many users ask the question - is it possible to open windows when the air conditioner is on? Today I will tell you how the room is cooled, and why open windows lead to breakdowns of “splits”.
Air conditioner according to the principle of operation is a normal household refrigerator, which also has two heat exchangers - one inside, the second outside. The power of the refrigerator compressor is designed for the volume of its refrigerator compartment. The door of such a household assistant is always closed, thanks to which a constant temperature is maintained inside. At the same time, the refrigerator motor works in normal mode for a long time and properly.
Now we understand the principle of cooling, but how does this maintain the desired temperature in the room? Everything is simple! A temperature sensor is installed in the indoor unit. As soon as the electronics of the “conder” understands that the temperature has been reached, the compressor turns off (the freon stops moving through the tubes). When the temperature rises in the room, the compressor turns on again. Maintaining the desired temperature, the motor turns on and off.
And now back to the topic of our article. If the windows are open, then the cold air from the room constantly leaves to the street! And since the electronics “understands” that the desired temperature has not been reached, then compressor does not turn off GENERALLY! Because of this electricity consumption increases. We can also refer to the disadvantages of such operation increased clogging of filters"split".
If the installed air conditioner is designed for only one room, but additionally cools neighboring rooms, then the “heart” of the air conditioner is loaded. Although this has a small effect in the form of lowering the temperature in the rooms. But cooling the street is generally a pointless exercise! If the compressor “threshes” without stopping, then sooner or later this will lead to its overheating and breakdown.
Try to ventilate the room with the air conditioner turned off! Or adjust the ventilation in such a way that the loss of cold is minimal. But keep in mind, if you are next to the window, then a cold stream can easily "through" you.

Conventional air conditioning allows you to cool the air in the room. But at the same time, it does not carry out an influx of fresh air, only powerful and functional ducted air conditioners and air handling units can handle this. As a result, an unfavorable stuffy microclimate is formed in a room without a sufficient amount of oxygen. In this case, the question arises: what will happen if you turn on the split system and open the window at the same time? However, experts do not strongly recommend doing this.
You don't know why you shouldn't open a window while the air conditioner is running. Today we will tell you more about this. In the event that it is very stuffy and hot outside in the summer months, then keeping the doors ajar while the device is running is pointless and even dangerous in some cases, because:
- equipment under such conditions functions inefficiently, and the room will still be very hot;
- the device in such a situation works constantly, as a result of which all internal components wear out and break faster;
- such an enhanced mode of operation can also lead to maximum electricity consumption and significant financial costs.
If you want to keep your home fresh and cool, then you should find out why you should not open the window while the air conditioner is running. In a room with closed window and door openings, the air becomes dry and cold, but if they are opened, the operation of the device will be reduced to zero.
Experts say that with open windows, the volume of air in an apartment or house increases significantly and is regularly updated. As a result, if an air conditioner is installed in this room, it will have to work hard and use a large amount of electricity to reduce its temperature. In this case, the newly cooled air mass will exit the window opening to the street. Thus, a vicious cyclical circle is obtained.
As a result, the equipment will constantly work, which will lead to its frequent breakdowns and wear. Such air exchange is not optimal, since it negatively affects the functioning of the equipment. In this case, the amount of electricity used to operate the device will lead to large financial costs.
The most common reason why windows should not be opened when the air conditioner is on is the possibility of quickly clogging the filters installed inside the device. When the window opening is wide open, a large amount of dust, pollen and small particles of debris enter the room. At the same time, a dirty filter leads to inefficient operation of the device, indoor air pollution and possible damage to the device.
Another reason is the risk of colds. In the event that a window opening is opened in the room with the split system turned on, then cold and warm air masses circulate. As a result, a person can initially cool down, and then overheat, which leads to illness.
Thus, the room should be regularly ventilated. At least two or three times a day, and even more often in the hot summer months. Only after that should the climate equipment be turned on. Also in this case, the installation of a compact supply structure will help, which will allow you to regulate the flow of fresh air into the apartment.
You are faced with the question of why you can not turn on the air conditioner with an open window nearby. Everything is very simple here. Indoors, to create comfortable conditions, constant air exchange is necessary. As a result, the windows in the apartment must be opened regularly. However, the efficiency of the split system will be low.
