People often wonder whether it is worth installing an air conditioner in an apartment, office or other premises. Therefore, I propose to talk about various misconceptions associated with the purchase and operation of an air conditioner. Having analyzed the main questions related to the problem posed, we will make a list of the most frequently asked ones and try to give answers to them.
- Does the air conditioner spread various harmful microorganisms?
- Does using air conditioner cause allergies?
- Does using an air conditioner harm your hearing?
- Does the air conditioner dry out the air?
- Does the air conditioner supply air from outside?
- Can an air conditioner be used to heat rooms?
- Does air conditioning 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 air conditioning in a child's room?
- Should I install a more powerful air conditioner?
When using air conditioning, you can only catch a cold if you use it incorrectly. Many people, trying to create significant coolness indoors in the summer heat, set the air conditioner to a temperature that is very different from the temperature outside. When entering such a room from the street, a temperature difference is created due to the difference in temperature in the room and in the environment. This may cause you to feel unwell. To prevent such problems from arising, air conditioner manufacturers recommend not creating a difference of more than 5 ⁰C between the temperature outside and indoors. Or, when entering from the street, slowly lower the temperature, allowing the human body to get used to it.
Also, of course, the cause of a cold can be the direct flow of cool air onto a person. In the same way, you can catch a cold while sitting under open window. To avoid this problem, operate your air conditioner properly. Modern models have comfort modes in which cool air is distributed throughout the room in the right way. The dampers of air conditioners perform automatic oscillations down and up, during which the cooled air is evenly dissipated inside the room.
There is also a mode in which the blinds direct a flow of cool air along the ceiling, and since cold air always goes down, the room gradually cools down. And, of course, to avoid catching a cold, observe the temperature regime. Manufacturers advise not to set the temperature above 22 ⁰C. This way you will create a comfortable environment and eliminate the risk of colds.
2.Is the air conditioner a spreader of various harmful microorganisms?
A warm and humid environment is most favorable for the growth of a variety of bacteria. In modern air conditioner models, condensate is kept 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 clean the air in the room. And, of course, it is recommended to clean the filters on time various contaminants and replace them. As the manufacturers recommend, this cleaning procedure should be performed approximately once a month. Some modern models equipped with self-cleaning filters. They can be cleaned and replaced less frequently.
3.Does using air conditioner cause allergies?
As for allergic reactions, then they are only possible if the filters of your air conditioners are dirty. Filters rough cleaning are subject to restoration, so keep an eye on them. Clean them at least once a month. And since fine filters cannot be restored, simply replace them every 2 to 3 months. And the allergy problem will be solved.
4.Does using an air conditioner harm your hearing?
Basically, the noise level created by an air conditioner is no more than 35 dB, and individual models- about 21 - 24 dB. Taking into account permissible level noise 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 particularly sensitive people, you can use silent air conditioners for apartments.
5.Does the air conditioner dry out the air?
According to standards, indoor air humidity should be 30 - 60%. Yes, air conditioners dry out the air a little, but the humidity parameter will be 30 - 40%, which is normal. Don't forget high humidity promotes the growth of mold, which can affect your well-being. Therefore, additional drying of the air will even be beneficial.
6.Does the air conditioner supply air from outside?
Many people think that an air conditioner has two tubes through which air enters and leaves the room. In fact, the tubes are designed to allow refrigerant to circulate 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 runs it indoors. Cooling occurs due to the passage room air through heat exchanger indoor unit of the air conditioner. In this way, the cooled air is returned to the room. This is how it works indoor unit air conditioner
Freon is absolutely safe for air conditioning. This is the gas that powers the air conditioner. It can only cause harm if you inhale it deeply, which can only happen if there is a serious leak. And such a situation can arise mainly in the event of an accident and on large powerful systems. Therefore, if you entrust the installation of the air conditioner to professionals, such a situation will not arise.
8.Can an air conditioner be used to heat rooms?
Despite the fact that many models have such additional function air conditioner, as a room heating, it is less effective compared to conventional heaters. Therefore, in the cold season, it is still not recommended to overload the air conditioner, since such prolonged loads negatively affect the operation of the device.
9. Does air conditioning make the air “dead”?
The air in any room contains small particles called aerons. They are very beneficial for human health. A common belief is that air conditioner filters trap these particles, causing the indoor air to become “dead.” This is a false opinion, because filters are capable of catching small debris, but not as small in size as aerons that are useful to our body. You don't have to worry about the air condition.
10. Is it necessary to ventilate the room when the air conditioner is on?
Don't confuse air conditioning with ventilation. Air does not leave the room and does not enter it. The air already in the room circulates and passes through the refrigerant for cooling. Despite the fact that there are air conditioners with a mixture of fresh air, it is still recommended to sometimes ventilate the room in order to throw accumulated carbon dioxide outside.
11. Will the air conditioner fit into the interior of the room?
IN office premises Most often, such a problem does not arise, since the design usually includes a “European-quality renovation” style. If we talk about residential premises, then, if necessary, you can perform hidden installation air conditioner But in many cases, the air conditioner compares favorably with the rest household appliances fits perfectly into the interior.
12.How harmless is it to use air conditioning in a children's room?
If you want to take care of peaceful sleep your baby, 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 building. It is also necessary, in addition to the desired temperature, that the air in the children's room be 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 small room, then you should not install a heavy-duty device. Excessive air flow can lead to colds. If the room is large, then an air conditioner with low power will suffer from overheating. Typically, 2 kW air conditioner models require approximately 0.7 kW, and consume less energy than many household appliances.
Good luck in choosing an air conditioner!
Most indoor air conditioners can only reduce the temperature, but they do not supply fresh air. As a result, in rooms where there are many people, there is sometimes a lack of oxygen, which provokes a state of suffocation. That is why many people are interested in whether it is possible to open windows while running. The relevance of this topic is also determined by the results of the experiment that if the windows are closed and the air conditioner is running for a long time, then an excess of carbon dioxide, and this, as is known, is harmful to the general condition of the body. That is why it is worth understanding this situation in as much detail as possible, taking into account all the nuances.
Why can't you turn on the air conditioner with the window open?
If the cooling equipment is working, then an open window not only resists the cooling of the room, and sometimes even makes it pointless, but also causes several negative consequences, which cannot be ignored.
Why you shouldn't open the windows when the air conditioner is running:
- The volume of air in the room increases, which means that in order to reduce its temperature, equipment has to work harder, spending more time and energy on cooling the room. In addition, the cooled air comes out, being replaced by warm air. This mode of operation negatively affects the condition of the air conditioner and also increases energy consumption, which will affect utility bills.
- Operating with an open window, the air conditioner clogs much faster. To avoid equipment breakdowns, you will have to clean the filters more often than usual. This is due to the fact that when the window is open, large number dust, pollen and other debris. As a result, the air conditioner does not work as efficiently and the air in the room itself is also polluted.
- Many people know that if you sit under air conditioning for a long time, you can catch a cold. Scientists have proven that operating an air conditioner with open windows significantly increases the risk of developing the disease, since in such a situation it will not be possible to avoid drafts. This is especially dangerous for children.
From this we can conclude that an air conditioner and an open window in a room are two incompatible concepts. It is best to ventilate the room several times a day, but the equipment should be turned off. In this case, you will receive cooled air saturated with oxygen.
It's no secret that in the summer indoors - be it city apartment or a private house in nature - the temperature often rises above comfortable. It gets hot, open windows don’t help, or even vice versa - they let hot air in from the street, you don’t want to do anything and many people dream of coolness.
It is necessary to immediately make a reservation that the concept of “comfortable temperature” is a relative concept. There are people who are quite satisfied with warming to 30-32°C and, moreover, if this does not happen, then the summer, so to speak, has passed in vain. The differences are especially noticeable in office premises - when, with the start of the summer season, irreconcilable wars begin between those who are STUFFY and those who are BLIND.
What is a comfortable indoor temperature in summer?
In this material we will talk about generally accepted temperature conditions. Currently, the Chief State Sanitary Doctor of the Russian Federation has developed optimal (recommended) standards for air temperature in residential premises (SanPiN 2.1.2.2645-10). According to these standards optimal temperature for a living room in the warm season it should be in the range from 22 to 25°C, and the maximum permissible is 20 - 28°C.
The traditional solution to maintaining a comfortable indoor climate is to use an air conditioner. However, this is also one of the common causes of colds. Moreover, if there is a child in the house - the topic safe use air conditioning equipment is particularly acute.
How to avoid catching a cold while in an air-conditioned room?
To avoid catching a cold from the air conditioner, you should follow these rules:
- the difference between the temperature outside and the temperature set on the air conditioner should not exceed 7 degrees (ideally, the air conditioner temperature should not be lower than 23-24°C)
- The air flow should not be directed towards a person. To regulate the direction of flow, use the “blinds” built into the air conditioner - vertical partitions that can redirect the air flow to the left or right. In addition, it is worth directing the flow of cold air to the ceiling - this way it will be distributed more evenly throughout the room.
- set the air flow rate to the lowest speed - the room will cool more slowly (but it will still cool down in 15 minutes), but no one will be blown away.
- install directly under the air conditioner protective screen- this way the air flow will be further dispersed.
- close the curtains or blinds - do not let the sun heat the room - this will cool the air without resorting to extreme air conditioning temperatures.
- close the windows and doors in the refrigerated room (below we will explain how this will help prevent colds).
- Clean the air conditioner filters regularly (bacteria accumulate and multiply on them, and if the filter is heavily soiled, this dirt begins to forcefully spread throughout the room with air currents. This is especially true when the device is started for the first time in a season).
Let's take a closer look at some issues.
What room temperature should the air conditioner maintain?
Modern models of air conditioners (even the simplest ones) provide the ability to create a temperature of +18°C even with increased outside temperature up to +40°С. But few people know that sudden changes surrounding a person temperatures of more than 7°C lead to acute respiratory diseases (ARI, ARVI), in other words, to a cold, and then to pneumonia. The way out of this situation is to bring the temperature in the treated rooms closer to the temperature environment or eliminate frequent changes in ambient temperature.
With a difference of 7°C, colds do not occur, but the feeling of comfort in the room remains. It follows from this that if the temperature outside is +30°C, then the temperature in the room needs to be set to +23°C - +24°C. Comfort for people staying and re-entering the premises will remain the same, and the risk of disease will be reduced. In the case when a person is constantly in a room for a long time and there is no sudden change in temperature (there are no movements “street - room - street”), then the temperature in the room can be set below + 23°C.
Why can't you turn on the air conditioner with the window open?
We remind you that doors, windows, vents must be closed when the air conditioner is on! Why? While cooling the room, the air conditioner does not always supply a strong flow of cold air - having cooled the room to the set temperature, it subsides and picks up speed again only when the temperature begins to rise again. In fact, this means that in an effectively cooled room a person does not always sit under a stream of cold air - at the moment when the air is cooled, the air conditioner practically does not blow.
It should also be noted that from open door and the windows there is a constant influx of hot air and the air conditioner actually works to cool the street. This, firstly, does not allow the device to effectively maintain the desired temperature in the room, and secondly, it makes it work for wear (it tries to lower the temperature, but it does not decrease, that is, it will blow incessantly), which significantly reduces its service life. services. Since a person still needs an influx of fresh air, it is permissible to open a window for ventilation (that is, literally just a crack!).
Why is it important to ventilate the room even if there is air conditioning?
You need to know that the usual wall mounted air conditioner has nothing to do with ventilation of the room. That is, the air conditioner cools and circulates the same air inside the room. The functions of the block hanging outside the window include removing excess heat from the room to the street, but no AIR EXCHANGE occurs. Therefore, it is necessary to ventilate the room regularly and repeatedly throughout the day. To do this, you need to turn off the air conditioner, open the window, at the same time you can open the door (then ventilation will be more effective) and allow the air in the room to refresh for 5-10 minutes. It is highly advisable to carry out ventilation at a time when there are no children in the room (and newborns should absolutely not be exposed to a draft) - that is, to ventilate the room when the child is on a walk, has lunch or is in another room.
How to make staying in an air-conditioned room more comfortable?
A running air conditioner not only cools the air in the room, but also dehumidifies it. And even if you are not sitting under a stream of cold air, and the room temperature is maintained within the recommended limits, you can still get a runny nose and sore throat. This is caused by the fact that the mucous membrane of the nasopharynx can become very dry and irritated - hence the stuffy nose and soreness. Not everyone's body reacts to air conditioning in this way, but if you know that you are prone to such a reaction, take measures to maintain normal humidity in the room. Humidity between 40 and 60% is considered normal; the humidity level can be checked using a hygrometer.
An ideal assistant in maintaining optimal humidity There is an ultrasonic air humidifier at home, and it will be useful not only when paired with an air conditioner. Usage ultrasonic humidifier air relieves cough and runny nose when a cold has already begun.
If you don’t have the opportunity or desire to use a humidifier, you can simply drop Aquamaris or regular saline solution into your nose as needed - this will protect the mucous membrane from drying out and maintain a feeling of comfort in a room with dry air. Saline solution is much cheaper than Aquamaris; it can be purchased at a pharmacy or.
Is air conditioning a breeding ground for germs and diseases?
Indeed, the air conditioner has special filters installed that are designed to trap small particles of dust and debris that get inside the device. If you do not clean the filters, pathogenic bacteria begin to accumulate and multiply in them, so they must be washed regularly. Depending on the dustiness of the premises, the period between filter cleaning can vary from once a month to a year.
The effect of a running air conditioner on a child.
Of course, the fragile bodies of children are most sensitive to temperature changes, drafts and, as a result, respiratory diseases that threaten them. Of course, if possible, the child should not be in a refrigerated room. As a last resort, the device can be set to the lowest setting and under no circumstances allow the baby to be under a stream of cooled air.

We have been thinking about buying an air conditioner for a long time, but we recently had a baby and we are afraid that he will catch a cold. After reading this article, I think we will finally buy an air conditioner, because now we will know how to handle it correctly, what temperature to set, etc. .p, thank you!
If the room is equipped with an air conditioning system, it often appears controversial issue: Is it possible to turn on the air conditioner with the window open? Some open the window and say that this can be done, others, on the contrary, close all the windows and doors and insist - under no circumstances should this be done! So who to believe? Information about the operation of the air conditioner and an objective judgment will help you understand the issue.

What temperature is considered comfortable for the average person?
During cold weather, a person begins to chill and freeze, and during hot weather, he begins to sweat and overheat. At the same time, working capacity decreases, and during overheating, heat stroke may occur. To prevent this from happening, you need to maintain a comfortable human body temperature range from 18 to 25 degrees Celsius.
If in winter time help warm the living space heating devices, then in warm times The air conditioner copes with this task for years.
How does air conditioning work?
Air conditioning systems can be divided into three types according to their operating principle:
- The supply type of air conditioning uses air that is not in the room (or outside).
- Recirculation type - uses indoor air only.
- Recuperation type - can use air both outside and inside the room.
All types of air conditioning systems share a common operating mechanism - for cooling, air passes through the system with a cooler. Freon gas is used as a coolant.
Note! The main reason why you want to open a window when the air conditioner is running is the flow of fresh air into the room. Simple air conditioners this is not provided, but this is feasible with air conditioning systems with supply and exhaust ventilation. Supply system provides the supply of fresh air to the room, and the exhaust - removes polluted air from it. But these solutions have an appropriate price.
Open the windows with the air conditioner on. Causes and consequences
Modeling this situation will lead to the following conditions:

Important! Temperature It is also important to observe in the case of refrigerators. An explanation of this is given by the article: “Is it possible to put hot food in the refrigerator?”
Will the air conditioner break down if the window is on?
The main cause of air conditioner failure is water hammer. It can appear for several reasons, some of which are quite common:
- Low temperatures. When in the room minus temperature, the air conditioning system can quickly fail. Of course, few people will open the windows so much that the temperature in the room becomes sub-zero, but this must be remembered.
- Clogged filters. Basic and satisfied common reason, which was mentioned above. Polluted, “dusty” air from a window can quickly “break” the air conditioner.
Advice! Dust causes windows to become dirty. Find out how to properly clean windows without streaks.
Prolonged operation of the air conditioner with the window open can lead to rapid wear of the compressor and fan.
Advice! If you need to bring fresh air into the room, briefly open the window for ventilation and turn off the air conditioner. Then close the window and turn on the cooling device again.
In conclusion, I want to say: you are the master of your equipment and only you can decide how to manage it. Air conditioning system engineers advise not to open windows while operating this equipment, so as not to void the warranty, reduce service life, or break the air conditioner.
A conventional air conditioner cools the air in a room. But at the same time, it does not provide an influx of fresh; only powerful and functional ones can cope with this. duct air conditioners And air supply units. 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 at the same time open the window? However, experts strongly do not recommend doing this.
You don't know why you can't open a window when the air conditioner is running. Today we will tell you more about this. If 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 in some cases dangerous, because:
- equipment functions ineffectively under such conditions, and the room will still be very hot;
- in such a situation, the device works constantly, as a result of which all internal components wear out and break faster;
- This enhanced mode of operation may also lead to maximum flow electricity and significant financial costs.
If you want your home to feel fresh and cool, then you should know why you should not open the window when the air conditioner is running. Indoors with windows and windows closed doorway the air becomes dry and cold, but if they are opened, the operation of the device will be reduced to zero.
Experts say that when the windows are open, 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 be forced to work hard and spend a large amount of electricity to reduce its temperature. In this case, the newly cooled air mass will exit the window opening onto the street. Thus, a vicious cyclical circle is obtained.
As a result, the equipment will constantly work, which will lead to 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 that the filters installed inside the device can quickly become clogged. When the window opening is open, a large amount of dust, pollen and small particles of debris enter the room. In this case, a dirty filter leads to ineffective operation of the device, indoor air pollution and possible breakdown of the device.
Another reason is the risk of colds. If a window opening is open in a room with the split system turned on, cold and warm air masses circulate. As a result, a person may initially become cold and then overheat, which leads to illness.
Therefore, you should regularly ventilate the room. At least two or three times a day, and even more often in the hot summer months. Only after this should you turn on climate control equipment. Also in this case, installing 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’t turn on the air conditioner with an open window nearby. Everything is very simple here. In the creation room 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.
