Does the air conditioning work, do you need to close the windows? When can I open windows after wallpapering. What is a comfortable indoor temperature in summer

21.04.2020

Is it possible to open a window when the air conditioner is on, or is it possible to turn on the air conditioner when the window is open - the question is, in fact, the same. The answer is unequivocal: not recommended. Next, we will explain in detail why.

An open window when the air conditioner is on not only interferes with the cooling process itself, but can also cause damage to the air conditioner. Here are just a few reasons why you should not open windows when the air conditioner is on:

The volume of air increases significantly. This leads to the fact that the air conditioner spends much more energy than it would have in a closed room. In addition, all the air that is cooled by the air conditioner goes outside. Thus, you force the air conditioner to cool the street while the room continues to receive hot air. But the excessive operation of the air conditioner can affect not only its durability, but also include a substantial amount in utility bills.
The air conditioner, which was turned on with the window open, quickly becomes dirty. This means that it will have to be cleaned more often from dust and other debris.
It's no secret that the air conditioner is better to turn on for a short time, because it can cause a cold. It is one thing when, having cooled the air, the device turns on the standby mode. And it is quite another when it blows endlessly, doing useless work.

The ideal solution will first ventilate the room, and only then turn on the air conditioner. Alternating one with the other, you will get both oxygen and cooled air in the room.

After all, you know, yes, that the air conditioner does NOT take air from the street, but works in a closed cycle. Therefore, it is necessary to ventilate the premises in any case!

That's all. We hope that the material was useful to you.

Why can't you turn on the air conditioner with the window open?

If the cooling technique is working, then an open window not only opposes the cooling of the room, and sometimes even makes it pointless, but also causes several negative consequences that cannot be ignored.

Why you shouldn't open windows when the air conditioner is on:

The volume of air in the room increases, which means that in order to reduce its temperature, the equipment has to work in an enhanced mode, spending more time and energy on cooling the room. In addition, the cooled air goes outside, 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 becomes clogged much faster. To avoid equipment breakdown, you will have to clean the filters more often than usual. This is due to the fact that when the window is open, a large number of 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 the air conditioner for a long time, you can catch a cold. Scientists have proven that the operation of the 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 air conditioning 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 must be turned off. In this case, you will receive cooled air saturated with oxygen.

Summertime (especially in the southern regions) can raise temperatures up to + 35, +40 degrees Celsius. Cars with such indicators simply heat up (even if they are not in the sun). How to properly cool the interior of the car? Ventilate or turn on the air conditioner? Or can you open the windows when the air conditioner is on? Let's figure it out? As usual there will be an article + video version ...

There are only a few persistent myths, for example:

Do not open windows if the air conditioner is on - the latter will break
Do not open when the cooler is running - because you can get sick
Open windows use MUCH less fuel

Here, as usual, there is some truth, there are pure myths - let's figure it out.

What should be done?

At the very beginning I will tell you how to do it. If the car is very hot, then you can first open all the windows (or at least the front ones) and drive a few hundred meters there, the oncoming air flow will cool the interior. Excessively heated air will come out of the car - then you can already close the windows and turn on the air conditioner, it will come to its power so corny faster and cool the interior faster.

This is the most best way cool the cabin in the heat. It doesn't matter what you have installed, air conditioning or climate control

However, not many do so.

The air conditioner will break - if you open the windows?

Why did so many on the net take this? Why should it break, for what reason? It has worked and will continue to work - it’s just that the energy that goes into cooling the cabin will go to waste.

When you open the windows, cool air will simply fly out the window, and warm air from the street will come in its place.

BUT the air conditioning system worked and will continue to work normally.

If you have climate - control, in the "AUTO" mode (it has a temperature sensor), it can add momentum and will work at full power, trying to catch up with the desired temperature.

However, no damage will occur. The air conditioning system is designed for such loads, withstands them without problems.

So if you want to ride with air conditioning and open windows - RIDE, but there is VERY LITTLE sense in this!

If I open the windows, I'll get sick!

There is a myth that cold air from the passenger compartment, mixed with hot air from environment and all at once a disease.

Is this not clear to me at all? For example, it is + 30 degrees outside, + 22, +23 degrees in the cabin, even if you open the glass, mixing will occur - cold air will come out and warm air will come in, nothing bad will happen. What do you get sick from? YES, and the difference is only + 7 degrees, this is not critical.

You can get sick if you lower the temperature inside the cabin too much, for example, to + 18 degrees and direct the air duct nozzles towards yourself. Sit down hot and there is such an icy air, almost 100% that you will get sick.

It is also worth cleaning the air conditioning system every year (well, at least two years), changing the cabin filter (I advise at least once a year, I personally change it twice a year) - after all, a lot of garbage and all sorts of bad things settle in these systems, up to mold. And then we breathe it, it is this that can provoke various diseases, such as colds.

Increase in fuel consumption

When you turn on the air conditioner (or climate control), some write that fuel consumption increases. This is logical, open windows to ventilate the interior and save money. It's not always worth it! Why?

Consumption increases by an average of 1-3% with various conditions movement. The slower you move, the less it grows
On the highway, you may not notice the savings at all, when you are moving at speeds of more than 60 - 70 km / h and the windows are open, a parachute effect is created, which also slows down the car. It turns out that again the same 2 - 3% is spent on this effect, of course this is not comparable with the air conditioner consumption, but it is growing.

Of course, if you are in traffic jams, the expense will be higher here, because you have to pay for comfort. But on the highway there may not be any savings at all

Now a useful video version, watch

In conclusion, is it possible to open the windows when the air conditioner is on? Of course you can, why not? Nothing breaks and you don't get sick. I personally don't see the point in doing this. Because the cold air will evaporate very quickly, and you will waste the energy that was needed for cooling.

Personally, I always move with climate control, my air is directed to the windshield and legs, the cabin windows are closed, usually the temperature is set to +22 degrees Celsius. Very effectively saves from almost any heat.

Often, if an air conditioning system is installed in the room, a controversial question arises, is it possible to open windows when the air conditioner is running? Some open window vents to supposedly quickly ventilate the room, others say that this should never be done. So what to do in such a situation to open or not open windows?

What is a comfortable temperature for a person

For human body comfortable temperature ranges are from 18 to 25 degrees above zero. If the air is cooler, we begin to feel chilly and freeze, if it is higher, a person quickly overheats, efficiency drops, with too high rates and a poorly ventilated room, even heat stroke is possible.

In hot weather, to avoid uncomfortable conditions, an excellent solution to the problem is to use air conditioning.

The principle of operation of the air conditioner

In domestic conditions, three types of air conditioners working in different ways can be used.

Supply type air conditioners work using air from outside the room.
The recirculation type uses air masses only inside the building for its work.
Recuperative types of air conditioners can work both according to the first and second principles.

But all three types of devices work on the principle of cooling the air passing through the system with a cooler, which is freon gas.

From this comes the answer to the question of whether to open the window or not when the air conditioning system is running.

A few reasons why you should not turn on the air conditioner with the window open

A sharp increase in air volume

When the windows are open, indoors, the amount of air increases sharply and in significant volumes. The recirculation air conditioner working for cooling has temperature sensors, and the supply of more heated air forces it to work more to cool the increased volume of air masses. For this, a greater amount of energy and resource of the device is expended, and the cooled air will then go out into the open windows, and more light warmed up flow into the room. This will affect the operation of the air conditioner very negatively, as the device will constantly increase the power of its work. And of course, the consumption of electricity for enhanced operation of the air conditioning system will increase significantly.

In this case, the air temperature in the room may not change at all.

The supply and recuperation types of air conditioners under conditions of open windows will also increase the power of their work.

Dirty filters of the device

If a window with street air is open, dust will also enter the room. The busier the place near the house, the more dust is in the air masses. The operation of the air conditioner with open windows will be associated with filtering more polluted street air, and as a result, this will lead to accelerated clogging of the device filters.

To avoid damage to the air conditioner, the filters need to be cleaned, and ignoring this issue will lead to a decrease in the service life.

Risk of colds

When the air conditioner is on, a colder air flow is created in the building, simply a draft, and a person who is under such a flow for a certain time can easily get a cold. Manufacturers of air conditioning systems take this into account, so the operation of the device is based on a thermostat.

When the room temperature reaches the set temperature, the cooling operation is slowed down. The air conditioner picks up speed again when the sensor detects an increase in the indicator. That is, the device does not blow constantly. If you open the windows, a constant influx of hot air masses is forced to constantly cool the air, and the device will constantly create cold air flows. As a result, a cold is guaranteed. To avoid this, you need to close the windows when the air conditioner is running.

Can the air conditioner break when the window is open?

Most often, the main cause of breakdown of air conditioning devices is water hammer. It can occur for several reasons, but two are directly related to the issue.

Low temperatures. The air conditioning system may break down at a negative room temperature. It is clear that no one opens windows in winter enough to cool the air below zero, but it's worth knowing.
As mentioned above, this is clogging of the filters as a result of the ingress of polluted air.

And finally, if there is an air cooling system in the room, then why open the windows? After all, it is the hot outdoor air that causes the temperature in the room to rise, the building itself, with closed and tightly curtained windows and doors, warms up very slowly and to achieve outdoor temperature it won't take a day. If you turn on the air conditioner in the room, then with the windows closed, the temperature in the room will quickly drop, and will remain so for a very long time even when the device is turned off.

Wallpapering the walls during repairs is not the most difficult job, it can be done in a few hours with certain skills. But it requires skill and knowledge of the basic techniques and rules.

Quite often, while gluing walls, you can make minor mistakes, but they will nullify all efforts. For example, this applies to drafts.

It will be a mistake to ventilate the room immediately after all the work performed. You need to know that you need to withstand a certain period of time.

Microclimate

Before gluing the wallpaper, the microclimate of the room should be brought to optimal values.

The temperature should be in the range from +15 to +25 degrees. At higher rates, the glue will dry out very quickly, and high-quality gluing will not work, since you need to constantly glue dry strips and coat the walls again.

Humidity should be at least 50%, and it is better if this figure is raised to 60%. If you are doing repairs in summer time and the air is too dry, then you need to spray water from a spray bottle to humidify the room.

When the windows are located on the sunny side in the room, you can hang a curtain so that the space does not warm up to too high a temperature.

Important! Windows and doors should be kept closed during and after gluing.

How long does wallpaper dry

Different types of wallpaper require a certain amount of time to dry completely.

After gluing paper wallpaper- required a short time. In this case, the windows can be opened a day after the completion of work.

Paper based vinyl wallpaper dries in 36 to 48 hours. At this time, you need to open the door as little as possible, not to mention the windows. They must be kept closed for the entire period.

Vinyl on non-woven base dries even longer. They need from three days to a week. Forced drying is better not to use, as there is a chance to spoil your work.

Attention! It is necessary to allow the canvases to dry naturally, without the use of artificial heating or ventilation of the room.

Special care should be taken when gluing non-woven wallpaper for painting. They are allowed to dry for a week before starting to paint, as wallpaper that is not completely dry, under the weight of its weight and the weight of the paint, can simply slide down the wall.

Non-woven types are usually not a cheap wall covering, so you need to treat them after gluing with special attention. You can not often open the door, chasing air, changing the temperature and humidity of the room, and the windows must be constantly kept closed.

Why you can't open windows

While wallpapering, the windows must be kept closed, since the rapid drying of the glue leads to peeling and unnecessary work on gluing loose joints, and possibly the entire strip as a whole.

This is especially true of paper and non-woven wallpaper. Vinyl is less sensitive to changes in temperature and humidity, but it also reacts negatively to open windows and doors. It is necessary to close windows and doors for the entire period of drying of glue and wallpaper.

Drafts and sudden changes in temperature can cause blisters to appear on the wall surface, the canvases to partially come off or the piece to peel off completely.

In some cases, the work will have to be completely redone, and the peeled off wallpaper will be unsuitable for new gluing and the material must be purchased again.

Windows must be kept closed for at least 2-3 days. For some species it is better not to open even more.

Glue drying time

It is also necessary to take into account the drying time of the glue. Quick drying formulations are currently being produced. But they must also be dried for at least 36 hours in a room with normal microclimate indicators, and in some cases up to 48 hours.

Wallpaper should dry evenly in natural conditions, so do not turn on heating devices or arrange artificial ventilation.

Important! If repairs are made in summer period, and the temperature difference is not critical, then vinyl, and sometimes non-woven wallpaper, experts allow gluing with open windows.

After watching the video, you can understand why it is impossible to open windows and doors during gluing and for some time after it:

Wall preparation

When they go preparatory work to gluing, the windows are not only possible, but must be kept open.

It is necessary to clean all surfaces from former coatings - wallpaper, old glue or paint, putty cracks, remove all bumps on the walls. The putty must dry completely, after which the surface must be sanded with fine sandpaper.

Clean the walls of dust by brushing or collecting it with a vacuum cleaner. After that, apply a primer. It provides better adhesion of the wallpaper to the wall. The primer can be prepared by yourself from the purchased wallpaper glue. It must be diluted with water, taking two to three times more liquid than for preparing an adhesive solution.

It is necessary to coat the wall carefully, without gaps, otherwise the wallpaper may peel off at the joints, from above or below, or the entire canvas may peel off. How well the wallpaper will adhere to the wall depends on a well-primed surface.

Correctly and how well prepared the walls can be checked in a simple way: You need to cut off a strip of electrical tape and stick it on the wall. If, when removed, there are no small particles of plaster left on the tape, then the surface is ready. Wallpapering of walls is carried out only on absolutely dry walls.
