What to do if the air conditioner does not blow warm air.

Already at the end of May, the inhabitants of Russia felt that hot days were on their way. In the morning we started waking up earlier, but not because we had gone to bed earlier, but because of the hot sun rays that heated our rooms, from the sweat flowing in hail ... In general, everything speaks of the approach of summer and the heat that everyone was waiting for and from which soon we will all be so desperate to save ourselves.

The best remedy for heat is air conditioning. More and more Russian apartments can boast of this boon of civilization. But what if there is no air conditioning in the apartment? How to save yourself from the heat? Do not surrender to her mercy.

On the Internet you can find a huge variety of options. AiF.ru studied them and selected the four most effective ways that will help you survive without air conditioning even in the most extreme heat.

We close the windows

The heat that enters our apartments mainly comes to us through the windows. From there, the sun's rays enter the room, from which we begin to feel as if in microwave oven. From there, it penetrates into the houses and hot air, which then cannot be expelled from the apartment in any way.

How to deal with it? Everything ingenious is simple - you need to close all the windows as much as possible. And this applies not only to the usual meaning of this word for us - to close the doors. In general, it is necessary to block any communication between the apartment and the street through the windows.

Thick curtains are best suited for this, which will not allow the sun's rays to penetrate into the apartment. If you close them in the evening, then in the morning you can feel the difference compared to the previous day - the apartment will become noticeably cooler.

There is another option. It is ideal if you do not want to live all summer like moles in their hole without sunlight. This is about mirror film, which many glue on windows. It lets in some light and allows you to look out the window, but most it reflects the sun's rays, preventing the heat from penetrating into the room.

And of course, you should not follow the advice to open windows in the heat. If you do not have the opportunity to arrange a draft, this will only allow hot summer air to enter the apartment, and even with dust and smells from the street.

Get hydrated

Moisture also helps keep the heat out. And there are a lot of possibilities to use water for cooling rooms.

You can start, perhaps, with a spray gun. Periodically spraying moisture from it in the apartment, you can reduce the temperature inside. You should not overdo it with this matter either, if you do not want to turn the room into a steam room. It will be enough to spray water once an hour - an hour and a half.

An automatic humidifier can replace the fuss with a spray bottle. It will do all the work for you. To additionally cool the apartment, we can advise you to add ordinary ice to the container with water that will be sprayed in the apartment.

The next method is as old as the world - soak towels in cold water and hang them around the apartment. It will look at least strange, but it will still help to lower the temperature in the room - it has been tested by the generations of our ancestors.

Moisture can be used not only to cool the apartment, but also to save yourself from the heat. This can be either the usual wetting of the head in cool water, or the periodic adoption of a full-fledged cool shower. This will not make the apartment colder, but you can forget about the heat for a certain time.

As a last resort, you can combine the two the latest ways to fight the heat - hang a damp cold towel around your neck, as athletes do.

Turning off everything

It's no secret that everyone Appliances radiate heat during operation. Even the same refrigerator, which is supposed to cool, does this only inside itself. Outside, it gives off a huge amount of heat that remains in your apartment. Turning off the refrigerator, of course, is an extreme measure, but you can think about minimizing the use of all kinds of vacuum cleaners, hair dryers, curling irons, irons, computers and even TVs.

This advice especially applies to the kitchen, in which, as a rule, the air temperature is several degrees higher than in the rest of the apartment. In the heat, it is worth cooking less on fire - this greatly affects the ambient temperature.

You can turn off something else in your apartment. There is a heated towel rail in the bathroom. As a rule, it is connected to a pipe with hot water and, in addition to its main function, it also serves to heat the bathroom. But with shutdown central heating it does not turn off and continues to work for all year round. It can usually be turned off by shutting off the two valves leading from the riser to the heated towel rail. If there are no such valves in your case, you can try to wrap it with foil. This should prevent the penetration of heat from the heated towel rail into the apartment.

DIY air conditioner

If you do not have an air conditioner in your apartment and for some reason you cannot install it yourself, nothing prevents us from making a primitive air conditioner with our own hands. All we need is a bowl of cold water, some ice and an electric fan.

One fan will not be enough to cool the air in the apartment. It will only create the illusion of coolness by increasing the movement of air so that the sweat from your body evaporates faster. It helps a little, but does not save in a serious heat.

To correct the situation, it is enough just to put a bowl of water and ice in the way of the air from the fan. Cold evaporation from the basin will mix with air currents and spread throughout the apartment. This will immediately humidify the air and lower the temperature.

If there is no fan, then a bowl of ice and water will also be useful. By simply placing it close to you, you can make your stay in a hot apartment a little more comfortable.

It's no secret that indoors in the summer - be it city ​​apartment or private house in nature - the temperature often rises above comfortable. It gets hot, open windows do not help, or even vice versa - they let in hot air from the street, they don’t want to do anything, and many 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 up 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 space- when with the start summer season irreconcilable wars begin between those who are stuffy and those who are BLOWING.

What is a comfortable indoor temperature in summer?

In this article, we will talk about common 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 rules optimum temperature for a living room in the warm season should be in the range from 22 to 25 ° C, and the maximum allowable 20 - 28 ° C.

The traditional solution to the issue of maintaining a comfortable indoor climate is the use of an air conditioner. However, it is also one of the common causes for the occurrence of colds. Moreover, if there is a child in the house - the topic safe use air conditioning equipment is particularly acute.

How not to catch a cold while in an air-conditioned room?

In order not to catch a cold from the air conditioner, you should follow the following rules:

• the difference between the temperature outside and the temperature set on the air conditioner should not exceed 7 degrees (ideally, the temperature of the air conditioner should not be lower than 23-24 ° C)
• the airflow must not be directed towards the person. To regulate the flow direction, 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 - so it will be more evenly distributed throughout the room.
• set the smallest air flow rate - the room will cool more slowly (but it will still cool in 15 minutes), but it will not blow anyone away.
• install a protective screen directly under the air conditioner - so the air flow will be further dissipated.
• close curtains or blinds - don't let the sun heat up the room - so you can cool the air without resorting to the extreme temperatures of the air conditioner.
• close windows and doors in the refrigerated room (we will explain below how this can help prevent colds).
• clean the filters of the air conditioner regularly (bacteria accumulate and multiply on them, and when heavy pollution filter - this dirt begins to forcefully spread throughout the room with air currents. This is especially true during the first start-up of the apparatus for the season).

Let's take a closer look at some issues.

What room temperature should the air conditioner maintain?

Modern models air conditioners (even the simplest ones) provide for the possibility of creating a temperature of + 18 ° C even with an increase outdoor temperature up to +40°С. But few people know that sudden changes in the temperature around a person by more than 7 ° C lead to acute respiratory diseases (ARI, SARS), 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 avoid frequent changes in ambient temperature.

With a difference of 7 ° C, colds do not occur, but the feeling of comfort in the room remains. From this it follows that if the temperature outside is +30°C, then the temperature in the room should be set to +23°C - +24°C. Comfort for people who are and re-entering the premises will remain, and the risk of diseases will decrease. In the case when a person is constantly in the room for a long time and there is no sharp change in temperature (there is no “street - room - street” movement), 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? Cooling the room, the air conditioner does not always supply a strong stream of cold air - after cooling the room to the set temperature, it subsides and picks up speed again only when the temperature starts 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 windows constantly there is an 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 without ceasing), which significantly reduces its life. services. Since the influx fresh air a person still needs it - it is allowed to open a window for ventilation (that is, literally on a crack!).

Why is it important to ventilate the room even if there is air conditioning?

You need to know that a conventional wall-mounted air conditioner has nothing to do with airing the room. That is, the air conditioner cools and drives the same air inside the room. The functions of the block hanging outside the window include the removal of excess heat from the room to the street, but no AIR EXCHANGE occurs. Therefore, it is necessary to ventilate the room regularly and repeatedly during the day. To do this, turn off the air conditioner, open the window, at the same time you can open the door (then the ventilation will be more efficient) and let the air in the room be updated within 5-10 minutes. It is highly desirable to carry out airing at the moment when there are no children in the room (and newborns absolutely categorically should not fall under the draft) - that is, ventilate the room when the child is walking, having lunch or is in another room.

How can you make your stay in an air-conditioned room more comfortable?

A working air conditioner not only cools the air in the room, but also dries it. And even if you do not sit under a stream of cold air, and the temperature in the room is maintained within the recommended limits, you can still earn a runny nose and sore throat. This is due to the fact that the nasopharyngeal mucosa can become very dry and irritated - hence the stuffy nose and perspiration. Not everyone's body reacts to the air conditioner in this way, but if you know that you are prone to such a reaction, take measures to maintain normal humidity in the room. Normal humidity is between 40 and 60%, the humidity level can be checked with a hygrometer.

An ideal helper in maintaining optimal humidity at home is an ultrasonic humidifier, and it will be useful not only when paired with an air conditioner. Usage ultrasonic humidifier air relieves cough and runny nose with a cold that has already begun.

If there is no possibility or desire to use a humidifier, then you can simply instill Aquamaris or regular saline into the 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 is much cheaper than Aquamaris, it can be purchased at a pharmacy or.

Air conditioning - a breeding ground for germs, diseases?

Indeed, special filters are installed in the air conditioner, which are designed to trap small particles of dust and litter that get inside the device. If the filters are not cleaned, pathogenic bacteria begin to accumulate and multiply in them, so they must be washed regularly. Depending on the dust content of the premises, the period between cleaning the filter can vary from once a month to a year.

The effect of a working air conditioner on a child.

Of course, fragile organisms of babies are most sensitive to temperature extremes, drafts and, as a result, respiratory diseases that threaten them. Of course, if possible, the child should not be in a refrigerated room. In extreme cases, the device can be set to the smallest mode and in no case should the baby 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 not 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 do, etc. .p, thanks!

From year to year in the summer - the same thing: millions of people in the heat get colds from air conditioners in cars, offices and apartments. How, finally, to avoid this and not stay at home with a runny nose and sore throat, we asked the doctors of the Chaika clinic. After talking with them, we compiled a simple memo on how to properly use air conditioners.

Do not drop the temperature below 22 degrees

In the warm season, the optimum indoor temperature is 22-25 degrees. Even if you want to cool down quickly, you should not lower it below this. The acceptable corridor is from 20 degrees to 28. Anything outside of it will already harm your health.

Use humidifiers

Air conditioners dry the air a lot, the humidity in the room drops much lower optimal indicator in 60-65%, and as a result, dryness causes discomfort in the mucous membranes (eyes, nose and throat).

In a closed room, you can get sick from other things.

In an unventilated room, you can get sick not at all from the air conditioner, but, say, from a virus or infection. Or you may become allergic to fine dust in a closed room.

Don't create a draft

Drafts are generally a bad idea, and opening windows and doors while the air conditioner is running is definitely not worth it. In the heat, your immune system is already so weakened that it increases the risk of developing infectious diseases, and the draft insidiously acts only on a certain area of ​​​​the body, and your immune system may “forget” to turn on there defense mechanisms. As a result, this leads to hypothermia and inflammation. In addition, the directed flow of cold air can lead to other unpleasant consequences, such as muscle spasm.

Avoid sudden temperature changes

You should gradually lower the temperature in the room, and not turn on the air conditioner immediately to the minimum after you, hot, entered from the street. The smaller the difference between the temperatures inside and outside, the less stress for the body and, therefore, the lower the risk of exacerbation chronic diseases such as tonsillitis. And if you drink an ice cold drink at the same time, you will make it even worse.

In a word, you need to endure the desire to cool down quickly, and set the temperature to 24-25 degrees, at least at first, so that your body has time to adapt normally.

Set a special mode at night

At night, it is worth setting the temperature to 25 degrees. During sleep, the body temperature physiologically decreases, and the discomfort that occurs when falling asleep disappears. You should not sleep at all without a blanket, leave yourself at least a thin sheet.

If your air conditioner has a night mode, be sure to select it. And if not, choose a mode in which the air circulates under the ceiling or is directed to the wall opposite from the sleeper so that the cool air is dissipated. In no case should you direct air flows towards yourself. Children, no matter how hot they are, should sleep in pajamas and nightgowns.

Can't stand the cold in the office

Do not torture yourself or wrap yourself in warm clothes in the summer at work. If you feel uncomfortable and cold from the air conditioner in the office, tell your colleagues about it and turn off the air conditioner, or at least raise the temperature to a healthy 22-25 degrees.

Air conditioner needs to be cleaned

And the last. If you do not clean your air conditioner regularly, it will begin to circulate air and spread disease-causing bacteria.

Air conditioning units are installed in order to create comfortable conditions in room. Their main task is to cool the air. The heating function was considered secondary for a long time. But today, leading manufacturers have changed their approach to this issue. It turned out that the heating mode can be very useful when cold weather sets in, before turning on the central heating. But sometimes there are situations when the system starts to work incorrectly. Why is the air conditioner not blowing warm air? The reason may be wrong mode operation or failure of one of the elements of the cooling structure.

Air heating

In order to find out why the air conditioner does not work properly, you should understand how it heats the air masses. After all, initially, the cooling mode was considered the main function. It turns out that the design of individual mobile systems includes heating ceramic elements. In this case, their operation is similar to that of a conventional heater. The disadvantage of such devices is the high consumption of electrical energy.

Modern models use a different principle of operation when heating air. The refrigerant inside the structure changes the direction of circulation. The condenser and evaporative element change their roles. The air conditioner starts to cool the outside air masses. At the same time, warm air enters the room.

Operation of the cooling device at low temperatures, possible consequences

If the air conditioner does not blow warm air, you should find out if it is capable of operating in this mode. Not all designs can heat the air in the room with the onset winter frosts. Standard cooling systems operate in heating mode only up to a certain negative temperature. Usually this value should not exceed -5 °C.

When using such devices in conditions of more low temperatures significantly increases the likelihood of problems:

• the oil in the compressor becomes more viscous;
• the cooling substance changes its properties;
• dry start of the compressor can lead to its breakdown;
• work in extreme mode leads to rapid wear of parts and failure of the entire system.

An ice crust sometimes appears on the surface of the heat exchanger with the occurrence of frost. She melts periodically. Water flows into the tray. Ice forms in it. This may damage the fan. In addition, ice deforms the walls of the heat exchanger, leading to depressurization and leakage of the working substance.

Since heat enters the room from external environment, then when the temperature drops, the working conditions become more difficult. Air conditioner required large quantity energy to heat the air. When certain limits are reached, it can simply turn off and stop working.

Usually in technical specifications The device indicates the temperature range in which its optimal functioning is possible. These parameters should be taken into account and do not use the technique in extreme mode.

Causes of incorrect operation of the system in heat transfer mode, ways to solve the problem

The following reasons for the poor performance of the cooling device in the heat transfer mode may occur:

• ice plugs appeared in the connecting tubes. They impede the movement of the working substance. It is not possible to defrost during the winter period. You can not heat the main line. To solve the problem, switch modes of operation. This changes the direction of movement of the coolant. The external module heats up;
• the air conditioner does not have enough freon. This situation can occur in the event of a seal failure and leakage. gaseous substance. Technicians are called in to fix the problem. After finding problem areas, he closes them and fills the system to the desired level;
• on the surface internal parts dirt appears. It is necessary to periodically remove the decorative cover of the device and clean the main elements and filters;
• certain parts of the structure may break. Usually in this case, a fault code appears on the control panel. To restore the operation of the cooling device, a service wizard is called.

Sometimes immediately after turning on the device, it turns out that it does not work in heating mode. How to make the air conditioner blow heat? You don't have to panic right away. A similar mode of operation is associated with a change in the direction of movement of the coolant. This requires a certain amount of time. Also, if there is a negative temperature outside, the compressor must gain momentum. You have to be patient and wait.

The use of inverter designs

As mentioned above, classic air conditioning devices are not sufficiently adapted to operate in heating mode at low negative temperatures. They decrease efficiency, increase heat loss. The risk of compressor failure increases.

Inverter models can be used more efficiently for space heating even in fairly severe frosts. There is a way to increase the efficiency of work. The flow of external air masses mixes with the air in the room. In heating mode, a smaller temperature difference has to be compensated.

To improve the performance of air conditioners in winter period winter sets of equipment can be used. They consist of the following elements:

• a device that heats the drain system and external connecting pipes;
• Heating elements heating the fan and compressor;
• device for automatic adjustment engine speed when changing temperature parameters.

Installing a winter kit helps prevent damage to the outdoor unit when it is turned on in border conditions and prevents the formation of ice in the drain pipe.

Is it worth using an air conditioner to heat the room?

The use of a cooling structure for space heating has a number of advantages:

• enough moisture remains in the air;
• no carbon dioxide is released;
• heat output is greater than the amount of consumed electrical energy;
• microclimatic conditions in the room improve.

But along with the advantages, there are certain negative points:

• the service life of the air conditioner is significantly reduced;
• the oil thickens faster, its characteristics deteriorate;
• The efficiency of the device becomes less than the nominal value;
• increases the risk of failure of the cooling device.

The heat transfer of air conditioning equipment is quite high and economically justified. Modern models are able to work at low negative temperatures. But they are only an addition to the main heating system.

Office life and interaction with colleagues is not always an easy task, especially when the air conditioner in the office is on and someone is constantly unhappy with the temperature.

This miracle of technology often works both in winter and summer, but it is in the heat that the chance to catch a cold increases.

The women's site "Beautiful and Successful" will tell you what rules you need to follow in order not to catch a cold under the air conditioner in the office, and how to negotiate a comfortable temperature with other inhabitants of the office.

War for air conditioning or with air conditioning?

Air conditioning is not only a brilliant invention of civilization, but also a permanent object of office wars. This device greatly facilitates the workflow, giving coolness in the heat and warmth on frosty days.

But what for one is a “light sea breeze”, others feel like an icy February wind. For an organism with a weakened immune system, one such breath is enough to get sick. ARVI, tonsillitis, laryngitis, pharyngitis - the risk of all these diseases increases significantly with excessively cold air in the room.

Discuss at the meeting (calculate experimentally) what should be comfortable temperature air conditioning in the office for everyone. In the end, you can insist on compliance sanitary norms defined by law. And this is by no means the 17 degrees that the head of the department constantly sets.

Appeal to the fact that if you suddenly get sick, then all your work will fall on amateurs winter cold in hot August. You can turn the air conditioner on or off when everyone leaves for lunch. In fact, there are a lot of options for solving the problem, you just need everyone to want to solve it and appreciate each other's health.

Together, check that the system is regularly cleaned and decontaminated. The air conditioner turned on for the first time after winter should work for an hour in empty room at open windows. And the next time you start arguing about how to save yourself from air conditioning in the office, remember that in our country there are still many people who are forced to work without air conditioning at all!
