How to cool a room without air conditioning: salvation from the summer heat. Ways to cool the air in a room without air conditioning Ways to cool a room in the heat

17.06.2019

Cooling the air in the summer is one of the top priorities of a homeowner. How to use the energy that surrounds us for this purpose and make air conditioning practically free, this article will tell.

The importance of ventilation cannot be overestimated. We will not repeat what has been described many times and will focus on our own task - to cool and freshen the air in the house. Traditional ventilation systems can be quite expensive to install due to the cost of components and assemblies, as well as the cost of qualified installation work.

During operation, they consume a significant amount of electricity, especially for cooling the air mass, they emit a lot of heat and create noise. The system described in this article is easy to install, energy efficient, requires no special skills and is intuitive. It should be noted right away that due to its simplicity, it has limited functions, however, it provides for modernization at any site at any convenient time.

In our case, the term "recuperation" is a synonym for the word "heat exchange", therefore the concepts of "recuperator" and "heat exchanger" are interchangeable. At the physical level, the process consists in cooling / heating the air, changing its temperature due to the consumption of thermal energy, and then mixing. How and why this happens, we will consider further.

Stable energy source

In pursuit of the goal of lowering the temperature in the room in the summer, it is reasonable to ask the question: “Where to give the energy of the heated atmospheric air? How to cool it down? Here the forces of nature come to our aid. The fact that at a certain depth the ground temperature is constant will be our main argument in justifying the energy efficiency of the system.

The soil is capable of endlessly exchanging energy - cooling and heating any carrier (air, water), but only up to its own temperature at a given depth, which remains constant due to the relative stability of the earth's core.

International practice

Of course, we are far from the first to decide to use the infinite and free energy of the Earth. In European countries, which are commonly called developed (Germany, Sweden, Belgium, etc.), this energy has been used since the beginning of the last century. The progress made in this area is impressive.

Systems for heat exchange of water below ground level are called "heat pumps". Such underground and underwater devices heat and cool the premises of the entire house. Standard projects have been developed for any building and it is possible to transfer a house from a traditional (gas, electric) air conditioning system to heat pumps. In a similar, but more primitive way, this energy is also used in our country, arranging underground food storage facilities (cellars).

What is a good natural heat exchanger

The operation of our heat exchanger is based on the same physical process as in heat pumps. Focusing on economy, we use this principle, bringing it to our own needs and local realities.

Tasks that an adapted autonomous recuperator can solve:

Permanent natural ventilation closed doors and windows.
Rapid replacement of indoor air with fresh air.
Cooling the air in the room.
Preparing the air mixture for the next steps.

Advantages:

Absolute environmental friendliness. During the installation and operation of the basic system, toxic materials are not used and no heat emissions into the atmosphere occur.
Safety. The recuperator does not use electric motors (power more than 100 W), chemical agents, high voltage.
Simplicity and cheapness. For forced ventilation Only low power 100W fans are used. Ventilation takes place naturally.
Oxygen is not burned during operation.
Low level noise.

Flaws:

the basic system does not provide for filtration, humidity control, heating or other processing of the air mixture (but allows the possibility of installing the appropriate equipment later).

Simple and clear system

Autonomous heat exchanger for country house- this is a system of ventilation ducts, partially laid underground, included in the supply and exhaust ventilation circuit. In order to create such an “air conditioner”, it is not necessary to understand the intricacies of physical phenomena. Just knowing that it works is enough. You can verify this by going down in the heat to any basement, well or subway.

The principle of operation is as follows:

Atmospheric air passes through pipes laid in the ground with a constant temperature (usually from +4 to +10 °C).
In the underground part, cool soil absorbs thermal energy heated air.
The cooled air is delivered through the ventilation ducts to the premises of the house.
At the same time, the exhaust fan removes the saturated and heated air mixture (“old air”) from the room.

According to the principle of construction, such systems are divided into two main types: pipe and bunker.

Pipe - consists entirely of pipes. The design can be varied depending on site conditions. Suitable in case of reconstruction of a house without a capacious basement, but a lot of earthwork will be required.

Bunker or stone - the heat exchanger is a bunker filled with large stones. It takes up less space than a pipe one (you can arrange it in the basement of a house). Requires a basement or underground space. The best option for new construction.

We create an internal system of ventilation ducts at home

In both cases, the ventilation ducts inside the house will be located approximately the same. Let's start with them.

The primitive supply and exhaust ventilation system consists of external and internal ventilation ducts connected into one network. Air sockets are located in the upper diagonally opposite corners of the rooms. In one - inflow, in the other - exhaust. In a one-story building, the main air ducts can be located in the attic. In a two-story building, the supply and exhaust air ducts on the ground floor will run in ducts inscribed in interior decoration, second floor - in the attic. The location of the main air ducts should be determined for each house individually, taking into account the layout (location of walls and partitions).

Advice. Premises where it is recommended supply and exhaust ventilation: living room, bedroom, nursery, kitchen, dining room, cabinets, pantry, rest rooms, gym. In bathrooms and toilets - only exhaust. It is not needed at all in corridors, vestibules, halls and loggias.

Rules for calculating the system of internal ventilation ducts:

Pipe sewer diameter 250 mm for the distribution inlet and combined outlet channels. Estimated consumption - two lengths of the house + height of the upper floor + 20%.
Pipe sewer (gray) with a diameter of 150 mm. Estimated consumption - three times the length of the house + 20%. For two-story house with equal floor area + 50%.
Fasteners for the pipe (based on the material of the walls) at the rate of 1 pc. by 70 cm.
Insulation (roll mineral wool) - 1 roll.
Foam, sealant, decorative grilles.
Elbows, revisions, couplings (1 piece per 70 cm).

Attention! Do not use 90° elbows as this will obstruct the passage of air and create noise. Combine 45° elbows (following the sewer example).

If it is supposed to arrange a pipe heat exchanger in a one-story building, the supply channel will come out of the ground into a heat-insulated box outside the building and enter the attic. In a two-story one, it is better to bring it into the building at the bottom of the first floor and install an internal vertical (distributing) channel, which will then be led into the attic space.

When installing a bunker option in the basement of a building, a vertical distribution channel will exit the bunker immediately into the room. It is also possible to mount it outside.

An example of calculating the consumption of materials for the installation of internal channels at home

Let's take as an example cottage with an estimated ventilated area of 60 m 2, which will have approximately 100 m 2 of total area and approximate dimensions of 8x12 m:

Pipe 250 mm: 2 x 12 + 3 + 20% = 32 m.
Pipe 150 mm: 3 x 12 + 20% = 43 m.
Fasteners: 32 + 43 / 0.7 = 107 pcs.
Elbows, revisions, couplings - take for 1 piece per 3 m: 32 + 43 / 3 = 55/3 = 20 pcs.
Grids: 8 pcs. (2 for each room).
Switches: 4 pcs.
Foam, sealant.

Tube heat exchanger

In order not to complicate the calculations with mathematical calculations, we will provide the data of the tests already carried out in an averaged form, or rather their results.

The basic principle that must be observed when creating a system of pipes is that there must be at least one pipe of an underground channel per room. This will facilitate the operation of the fans due to atmospheric pressure. Now it remains to place the required number of pipes in the underground part of the site. They can be laid individually or combined into a common channel (250 mm).

V this description we propose to take into account not the maximum load, when all rooms are forcibly ventilated at the same time, but the average load, which will be supplied with regular periodic ventilation different rooms(as happens in real life). This means that there is no need to display a separate channel for each room. It is enough to bring 150 mm air ducts from each room to one common 250 mm duct. The number of common channels is taken from the calculation of one channel per 60 m 2.

We create a recovery field

Scheme of the device of the pipe heat exchanger: 1 - fan; 2 - channel in the trench ∅250 mm; 3 - rows of pipes ∅250 mm; 4 - recovery field.

First you need to choose the location of the pipes (recuperation field). The greater the length of the laid pipes, the more efficient the air cooling will be. It should be noted that after the work, this area can be used for planting, landscape design or playground. Never plant trees on the recovery field:

We excavate the soil to a freezing depth of plus 0.4 m.
We lay pipes of 250 mm in increments of at least 700 mm along the axis.
We bring the air intakes to a height of 1 m. It is desirable that they be in a shaded, but well-ventilated place.
With the help of knees and adapters, we combine them into a common channel of 250 mm, which is connected to the ventilation system of the house (see above).

Attention! In the underground part, use special ground sewer pipes with a thick wall. They do not need to be thermally insulated, but simply covered with soil, spilling water. Only concreting is allowed if necessary.

Calculation of the scope of work and material consumption:

For the recuperation field we take a plot of 15x6 m with an area of 90 m 2.
The volume of soil of the pit at a freezing depth of 0.8 m will be: V cat \u003d (0.8 + 0.4) x 60 \u003d 72 m 3.
The volume of the trench 40 cm wide (10 m from the house): V tr \u003d 1.2 x 0.4 x 10 \u003d 4.8 m 3.
The total volume of earthworks: V total \u003d V cat + V tr \u003d 72 + 4.8 \u003d 77 m 3.
Sections of 15 m: N neg \u003d a / 0.7 \u003d 6 / 0.7 \u003d 9 pcs., where a is the field width.
Total pipe length: L \u003d N neg x 15 + 10 \u003d 9 x 15 + 10 \u003d 145 linear meters m.
We accept consumption of elbows, couplings, adapters 2 pcs. x 15 m = 30 pcs.

Advice. The deeper the heat exchanger is laid, the more efficient its operation will be. More than one tier is allowed.

Bunker heat exchanger

If the house has unoccupied basements, they can also be used to build a bunker (air or heat exchange tank) for a stone heat exchanger. Its action is based on the energy intensity of the stone - it gradually gains temperature environment and balances the flow of passing air. In the absence of free space in the basement, the bunker can be arranged on a plot outside the house.

Scheme of the device of the bunker heat exchanger: 1 - fan; 2 - pipe Ø250 mm; 3 - protection; 4 - stone Ø200-450 mm; 5 - brick walls; 6 - cover

At a certain place, a pit is dug, approximately 2x3x3 m in size. From the exit point of the common channel of the ventilation system of the house to the pit of the future reservoir, a trench is made, a 250 mm pipe is laid into it to a depth of 140 cm, through which cooled air will be discharged from the bunker. Along the wall to which the trench approached, a vertical strobe is laid to the bottom under a pipe with a diameter of 250 mm. Then the bottom is laid out with bricks or concreted. The bottom of the air reservoir must be at least 1 meter deeper than the ground freezing level.

Attention! After the device of the bottom of the bunker, a 250 mm outlet pipe should be laid.

The beginning of the outlet pipe protrudes from the wall by 1/3 of the distance to the opposite wall and is lined with brick protection. A protective grid is installed on the inlet.

Filling the tank

It is better to lay out the walls from brick or cast from concrete (without slag!), since these materials conduct temperature better than others. The cinder block is not suitable because of its thermal insulation properties. The walls and bottom must be carefully waterproofed (roofing material) from the outside and plastered from the inside to prevent the penetration of organic matter or moisture. The height of the walls is up to ground level minus 20 cm. An inlet hole is arranged at the top of any wall and air intake pipes are installed. To facilitate the operation of fans, we recommend installing 3 pcs.

After the mortar hardens, the hopper must be filled with a large pebble stone. Size from 200 to 450 mm in diameter. The stone must be clean from organics, washed.

The tank is covered with a "lid" of continuous boardwalk on wooden beams covered with waterproofing materials. Sod is laid on top. Then the outlet pipe is connected to the ventilation system of the house (to the common ventilation duct) and backfilled.

Calculation of the scope of work and consumption of materials:

With an air tank size of 2x3 m and a depth of 3 m, the volume of soil (earthworks and stone for filling) will be: V \u003d 2x3x3 \u003d 18 m 3 + V tr \u003d 22.8 m 3.
Volume brickwork: V treasure \u003d S walls + S bottom x 0.125 \u003d ((2x3) x 2 + (3x3) x 2 + 2x3) x 0.065 \u003d 36 x 0.065 \u003d 2.34 m 3.
The total length of the pipe (10 m from the house): L = (10 + 3) + 10% = 15 m.
Number of knees - 6 pcs.

The cost of stone to fill the tank may vary depending on the region of construction.

As can be seen from the calculations, the final cost of air conditioning 1 m 2 for both options is different. The main factor of choice is the level of occurrence ground water. If it is high, less than 3 m, then it will not work to build a bunker heat exchanger. The pipe is suitable even with a 1.5 meter UGV.

Installing fans

The system presented here provides for the synchronous operation of two duct fans - supply and exhaust - installed in each air outlet of the room. This makes it possible to quickly deliver cool Fresh air into the room and remove the heated one. For effective ventilation, the fan power of 100 W each is sufficient. When choosing a fan, pay attention to the noise level during its operation.

Approximate cost of operation

If you ventilate each room three times during the day for 20 minutes, then we get 1 hour of operation of 8 fans of 0.1 kW each. This is less than 1 kWh per day. Per month - 30 kW. At a price of 5 rubles / kW, this will be 150 rubles / month.

The service life of recuperators and ventilation ducts at home is limited by the service life of the material. For underground elements - from 50 years, for internal - unlimited.

The system does not require maintenance (except for fans - once every 5 years).

prospects

The described scheme can become the basis of a more complex air conditioning system. It can gradually include additional elements - filters, heating and cooling coils, more powerful fans, blocks automatic control other. The air mixture prepared underground has a stable temperature not only in summer but also in winter, so it can also be used for heating.

Vitaly Dolbinov, rmnt.ru

Summer heat is not just tiring - it is dangerous to health: in hot weather, diseases of the cardiovascular system are exacerbated. Therefore, it is important to know how to cool a room in the heat, even if it does not have air conditioning. To do this, you need to act in several directions at once.

Sun protection

On a sunny day, infrared radiation, which freely penetrates through window glass, heats the walls and furniture in the room. The rooms, the windows of which face south, literally turn into gas chambers. At the first stage of the fight against heat, it is necessary to protect the room from the sun's rays.

There are several ways to do this:

one of the most effective options protection - a special coating on the glass. Such double-glazed windows are somewhat more expensive than usual, but quickly pay off due to the fact that they retain heat in winter, and in summer they prevent the room from heating;
glass can be pasted over with a sun-protection film. However, it is advisable to use it only in very bright rooms, since in cloudy weather the room will be even darker than outside;
light blinds block out most of the sun's rays, while not too darkening the room and not creating a gloomy atmosphere. But it is better that the blinds are fabric, as the metal plates heat up;
the same role as blinds is played by thick light curtains. They must be kept closed all day long;
if the window overlooks a balcony or a loggia, it is worth planting sun-loving plants there. Dense greenery is pleasing to the eye and creates a feeling of coolness.

Hot air protection

In hot countries, they never ventilate the premises during the day: hot air from the street does not bring the desired freshness, but only heats the room even more. Therefore, from morning to late evening, all doors and windows must be closed.

But after sunset, when it becomes cooler outside, you should open all the windows, or better, arrange a draft for a while. At night, if desired, you can sleep with open vents or windows, after tightening them with mosquito nets. But in the morning, before the onset of heat, the windows must be closed.

Humidify the air in the apartment

One of the reasons for the discomfort experienced in a heated room is the dryness of the air. But you can humidify it only if the room is protected from sunlight and hot air from the street.

Air humidification methods:

buy a humidifier. In stores - a variety of models for every taste. The design of such devices allows you to pre-set the operating time and humidity level, and water needs to be filled in every few days;
wash the floors in the bedroom at night;
using a conventional spray bottle, spray water every 1-2 hours. If you add a few drops of lemon or grapefruit oil to it, the air in the room will seem fresher and cooler. It is important not to overdo it, otherwise mold will appear on the walls;
buy an electric fountain. The murmur of water soothes and makes you forget about the heat;
hang a few wet towels in the room;
you can cool the room without air conditioning, and at the same time humidify the air with a conventional fan. If it has a grill that protects the blades, a damp towel is hung on it;
a more radical option: prepare a 10% salt solution (500 g per 5 l), fill it ¾ plastic bottles and place them in the freezer. When the liquid freezes, the bottles are stacked in a basin and placed in front of a floor or table fan that is turned on.

Cooling with a fan and plastic bottles with ice

Turn off electrical and gas appliances

Heat sources are TV, computer, electric hob, even washing machine and incandescent lamps. Gas stove and the oven heat the kitchen considerably. Electric and gas appliances it is recommended to use as little as possible and not during the day, but in the late afternoon, when the heat subsides.

Remove carpets and warm bedspreads

If possible, it is better to take out carpets and rugs from the room. It is recommended to replace woolen and synthetic bedspreads, capes on armchairs and sofas with linen ones.

Arrange a bedroom

In hot weather, bed linen should be changed every day, as it absorbs sweat. In summer, it is recommended to use underwear only from completely natural cotton, linen or silk fabrics.

If all the above measures are not enough, and it is impossible to fall asleep in the room due to the heat, it is necessary to cool the bed itself. Half an hour before bedtime put plastic bottles or ice packs in bed. Before going to bed, they are removed, because due to direct contact with ice, you can catch a cold. If you still can’t fall asleep, you can only cover yourself with a wet sheet.

Thermal insulation of the room

To keep a room cool for a long time in the heat, you need thermal insulation. If during the construction of the house the thermal insulation of the apartment was not provided, it should be installed during the repair (for apartments on the top floors, thermal insulation of the attic is very important). In a room with high-quality thermal insulation, in summer the temperature is 5 °C lower than outside. Glazing of a balcony or loggia also allows you to protect the apartment from summer heat.

Stuffiness and heat in the apartment interferes with normal living, working and sleeping. Well, if it is possible to install air conditioning, but what if it is not? Several simple tips help to cool the house down a bit.

Being in a stuffy room is not only difficult, but also harmful to health, but what to do if that very stuffy room is own apartment or house? It is not always necessary to resort to buying an air conditioner to lower the degree in the house, although, of course, it does the best job of cooling the rooms.

But in addition to the advantages, the air conditioner has disadvantages - someone may not be able to afford it, plus it consumes electricity, which is why the bill at the end of the month will come to you more. If you follow a few rules and tips, then the degree in the apartment can be lowered with improvised means.

Close your windows

V daytime open windows will not give you so much desired coolness, but on the contrary they will create in the room the greenhouse effect. So make sure all your windows and doors are tightly closed during the daytime. Moreover, it is better to close them in every sense of the word - hang thick light curtains and keep them drawn in the daytime.

To help cope with the heat and excessive sunlight, a reflective film that you can stick on the glass will also help.

Create a draft

In the evening, you still need to ventilate the apartment, but on the condition that you can create a draft, this is the only way you can get rid of the stuffy air, and not vice versa to catch up with it even more.

During airing, be careful and do not catch a cold, it is best to open windows and doors one by one - while one part of the apartment is aired, you rest in another, or you can go out into the courtyard for a while - just do not go far from the house and keep an eye on the apartment, because you have all windows are open.

Humidify the air

Moisture-laden air will help cool your apartment. You can create it using the most common spray bottle - fill it with ice water and spray the apartment every hour and a half. You should not do this more often, otherwise the effect of a bath will be created in the apartment and dampness will appear.

If you have a humidifier, then it will also do the job just fine - just fill the container cold water You can even add some ice to it.

Fan, ice and water

The simplest fan, ice and water will also help to cope with stuffiness. Fill a bottle with water (dilute it with salt so that the bottle does not burst) and put it completely frozen in the refrigerator, or take any cup or bowl and fill it with ice water.

Put bottles or a bowl in front of a running fan - this method will more than replace your air conditioner. Just like with air humidification, do not overdo it.

Get rid of everything superfluous

It is best to turn your apartment into the best work of minimalism for the summer. Remove carpets and anything that collects dust and heat around it. Floors without carpets can be wiped once a day, and the temperature in the apartment will immediately drop noticeably - and walking on such a floor in the heat is more pleasant than walking on a heated carpet.

sofas and upholstered furniture you can cover it with light natural fabric, and it is better to minimize the use of any equipment and lamps too - this way your apartment will heat up less, and your wallet will say thank you at the end of the month, when a utility bill arrives.

If you have such an opportunity, you can disable summer time and a serpentine in the bathroom.

Keep your bed cool

The heat makes it hard to sleep, so keep your bed cool. During the daytime, bed linen can be folded into bags and put in the refrigerator to cool. Yes, laying it out every day can be a real hassle, but you can limit yourself to only a few items - for example, cool only pillows or sheets.

A bowl of ice and water placed at the head of the bed can also help to cope with the heat.

The basic rules for keeping a room cool are: isolate it from direct sunlight, minimize the use of electrical appliances and dust-collecting materials, keep the air humid, and remember to let in cool air in the evenings or at night.

How to cool a room without air conditioning? Summer sun is hot, in the room + 30C - 22 tips on how to replace the air conditioner

Air conditioners generally appeared several decades ago, and domestic even less so.

Indeed, people lived without air conditioners! Let's see what to do if the air conditioner is not available and there is no way to purchase it in order to protect yourself from the heat, or at least improve the situation.

Tips for Cooling Your Home Without Air Conditioning

My mom had studio apartment in Kherson on the fifth floor of a 5-storey building with a flat bituminous roof. Trees don't reach that height.

The temperature in the summer reached + 35C in the room, the curtains burned out during the season (we will keep silent about tulle curtains) ...

The only thing that saved us a little was the canopy on the balcony, which was made of tarpaulin. After 3-4 years, it also had to be changed, but the window was still shaded, and the temperature dropped to + 30-32C.

Then the housing office put rafters on the roof and laid slate, the temperature in the room no longer rose above + 30C.

Hence the first conclusion: in any way create a shadow.

Consider more methods on how to cool an apartment in the heat without an air conditioner:

If the apartment (or house) is no higher than three floors, plant trees or climbing shrubs that creep along the walls so that they create shade
Cooling a room is simple: close windows and vents when the temperature rises above +25C, and open when it drops to 25C.
Summer sun is hot - if the windows are on the sunny side, close blackout curtains for the day, close the shutters (by the way, a very good thing: they provide security and protect from heat / cold), blinds or stick reflective film on the glass. True, it is better to use non-metallic blinds, since the metal will warm up in the sun and raise the temperature in the room even more.
How to cool an apartment: during the day, keep not only windows closed, but also entrance doors(including the entrance door) - this will reduce the flow of warm air into the apartment
If you install metal-plastic or PVC windows, order glass with reflective coating. Such a coating is visually imperceptible, but it retains heat in both directions: in winter outside, in summer - inside.
Protect the balcony from the sun: hang curtains (it’s better to take an inexpensive fabric, as it will burn out quickly) or bamboo mats, or better glaze the balcony and also use curtains, mats or non-metal blinds
How to cool an apartment without an air conditioner in the heat, if you are on vacation and cannot radically change something: just attach any paper, even a newspaper, to the glass with tape
In the evening and at night, arrange drafts, if the location of the windows in the apartment allows it.
Minimize the use of heaters and incandescent lamps, which produce appreciable heat. Go from hot dinner to cold okroshka
How they cooled a room without an air conditioner before: I remember as a child, when they didn’t even know about air conditioners, my mother always washed or just wet the floors in the heat before going to bed - the temperature in the room dropped
You can just hang wet sheets on doors and windows. But this method is only suitable in the absence of dampness in the apartment.
How to cool a room without air conditioning, but with a fan: it is preferable to use fans with an automatic change in the direction of the air flow, so as not to catch a cold. Can be used for desktop, floor and ceiling. True, the latter have a low speed of rotation of the blades and the result is appropriate. But you can find ceiling fans with rotating blades. In summer, they are installed so that the air hits the ceiling, that is, cooler air from the floor rises. In winter it's the other way around.
You can enhance the action of the fan by placing plastic bottles or other containers with ice directly in front of it. Place the container and bottles on a pallet so that the condensate that forms on them does not accumulate in puddles. Before freezing, the bottle must be filled ¾ of a 10% salt solution so that the ice does not break it. You can use such sources of cold repeatedly, re-freezing them every day. It's better to have 2 sets.
The same ice bottles can be placed on a chair at the head of the bed.
Hang your sheets out in the evening for fresh air to ventilate. You can put plastic bottles in bed beforehand or a heating pad with ice to cool it down. Just don't forget to clean up before you go to bed so you don't catch a cold.
How to cool a room with a refrigerator: You can even put bed linen in the refrigerator in the morning (if it has space not taken up by water bottles) and put it on before bed
Take off the carpets for the summer (it’s better to give them for cleaning, they’ll be ready for the fall) - it’s better to once again wipe the floors and walk barefoot in the house: it’s nice and not so hot ...
In the heat of the day, place a bowl of water and a napkin next to your bed. If you cannot sleep because of the heat, or wake up from it, wet your forehead, ears and hands. You can even cover yourself with a wet sheet.
How does insulation cool a room without air conditioning? Now thermal insulation of walls is widely used. When building a new house, be sure to consider such a design. So you can save on the thickness of the walls. Have you noticed that in old houses with thick walls, it is cooler in summer and warmer in winter?
