The cellar is a room, most of which is below the ground level. At the same time, its functions are not limited to the place for storing vegetables and other family supplies. In a modern private house, it is possible to equip a workshop, sauna, a hall for sports, billiard room, boiler room and a lot of things. But the main purpose of the cellar is the storage of vegetables, wines and other home billets, which significantly releases the place in the house. To increase the storage period, it is necessary that the temperature be within 5 degrees, the humidity did not exceed 90%, and the inflow of fresh air was carried out constantly. Therefore, the correct ventilation of the cellar is extremely important for maintaining the microclimate.

In addition, ventilation for the cellar is still necessary to ensure that the wiring laid in the cellar for its lighting has not been exposed to the excessive influence of humidity. Of course, electrical cables are paved in special sleeves, but the correct ventilation serves as an additional protective factor.

Purpose of cellar ventilation

It is properly designed and mounted that provides its proper functioning for its intended purpose. When the air flow in the needed for storage of vegetables quantities, their storage is in a state suitable for food, significantly increases.

If the premises of the cellar is badly ventilated, then the air is stirred in it, the microclimate, vegetables and other products are spoiled. After all, in the cellars, not only vegetables are stored, for example, there you can make many types of homemade sausages, and for them a violation of at least one of the records of storage and cooking threatens fast tongue.

However, excessive ventilation is also undesirable. After all, then a draft, which leads to the acceleration of drying of vegetables and sausages. So the right ventilation of the cellar must be ensured.

Therefore, it is necessary to take into account all factors: the size of the room, the possibility of connecting electricity to arrange forced artificial ventilation, waterproofing the walls of the cellar, the materials of the ceiling, the foundation.

Natural ventilation device

The principle of natural ventilation is based on the difference in indoor air pressure.

For the arrangement of the natural system for the cellar, 2 pipes are needed: exhaust and intake. Through the exhaust exhaust the exhaust air outward. In the supply - air enters. In order to make ventilation, use galvanized or asbetic products. In this case, the diameter of the pipe is calculated by the calculation: the area in 1 sq. M. will provide a pipe 26 cm.

The exhaust pipe is usually paved along the corner corner. The lower open its end is at an altitude of 140-150 cm above the floor level of the cellar, that is, almost under the ceiling of the room.

The exhaust design of the air duct is laid through all the rooms vertically, going out, it must be higher than the roof skate by 50 cm. In order for the condensate, the part should be accumulated on it. It is best for these purposes to use a pipe of a larger diameter into which the air duct tube will be inserted, and the interval between them will be filled with insulation, which can be used with a 50 mm thick mineral wool.

The supply tube of the ventilation duct is placed in the opposite corner of the cellar with respect to the exhaust pipe. Its open end is located below exhaust and is at a level of 40-60 cm from the floor of the cellar. The supply pipe of the air duct towers above the level of the zero point of the house at a height of about 80 cm.

It is the location of the ventilation air ducts that allows you to create a desired pressure difference for air in the cellar. If the temperature difference within the cellar is significant, then the draft is inevitable. To avoid this, it is necessary to provide for the installation of a special gate, which will adjust the flow of circulating air. Such valves are installed both on the supply and exhaust pipe. In addition, in order to avoid entering insects and midges in the cellar, the upper hole of the supply pipe is closed with a grid, which is periodically cleaning or replaced.

The benefits of the natural ventilation of the cellar are:

• low cost: costs will affect only pipes and insulation;
• electricity savings;
• the possibility of self-installation;
• no need for constant control - regulation is required only with a large temperature difference;
• the combination with other ventilation systems installed in the house, which allows you to additionally build forced ventilation for the cellar.

After the installation of ventilation pipes is completed, it is necessary to check their performance. To do this, apply a sheet of ordinary paper to one of the ventilation pipes. At the same time, if you apply it to an exhaust pipe, the sheet must be attracted to the pipe, and from the supply - slightly repel. In addition to the sheet as a test of ventilation, you can use the flame of the candle. To do this, you need to light the candle and bring to the exhaust pipe - the flame will change its direction towards the pipe. When the candle is tray to the supply pipe, the flame, on the contrary, will be directed towards the cellar. After successful verification, one of the ways the cellar ventilation system will be ready to work.

However, in the future it is necessary to carefully observe the condition of the air in the cellar. When sharpness, dampness, condensate on the wall or ceiling, should increase the efficiency of the ventilation system. This can be done by opening the valves or building forced ventilation.

Forced ventilation cellar: features

Mounting diagram of ventilation pipes in the cellar: A - supply pipe; B - exhaust pipe.

However, it is not always enough natural ventilation for full provision of placing fresh air. Therefore, if the area of \u200b\u200bthe room is significant, and the height is approaching 2 m, or the natural extract does not cope with its functions as required, then the device of the forced cellar system will be required.

The construction of an artificial construction is a rather complex engineering task, to implement which considerable efforts or attracting specialists.

Constructively, this ventilation is a sequential installation on a supply or exhaust pipe of such elements as:

• channel heater;
• channel fan;
• silencer of sounds;
• filtering cassette;
• channel fan;
• check valve;
• blinds and dooms pipes.

At the same time, channel fans are distinguished by their types and other technical specifications, such as capacity. The direction of the fans should be such that the air is going out when it is installed on the exhaust pipes and headed inside when mounting on the supply pipes. In this case, the pipes themselves can be positioned horizontally or vertically. The efficiency and durability of the ventilation system directly depends on the technical parameters of the fans.

Forced ventilation system is automatic and mechanical.

The presence of a celler in the house allows for a long time to store vegetables and preservation. The most important condition for this premises is to maintain the optimal temperature and humidity regime. After all, moisture can destructively affect not only products, but also other things stored in the cellar.

To avoid negative consequences, important attention is paid not only to waterproofing and insulation of the foundation, but also the right ventilation organization.

Efficient use of the premises is possible only when maintaining comfortable conditions for the content of fruits. To ensure their long-term storage, it is necessary to create a microclimate in which the level of humidity () could be adjusted.

The poorly ventilated premises is filled with moisture, which later settles in the form of condensate on the walls and drawers with fruits. All this becomes the cause of rotting vegetables and the appearance of a characteristic smell.

It is important to know how to properly make ventilation in the cellar, because the draft also destructively affects the fruit, drying them.

The main factors of stable operation of the system

The principles of the system are:

• air movement due to the heating of the ventkanal;
• the impact of wind blowing air masses from pipes.

That is, to ensure high-quality circulation operation when installing the main elements, you need to create a craving. The deflectors used in the windless are used less efficient. However, ventilation efficiency is not lost, since the main role is assigned to thermal motivation.

Despite the presence of a mass of advantages, still such a system has some disadvantages associated with the effect of temperature. So during the heat due to the lack of wind, the work of the ventilation at home can deteriorate. In winter, the pipes can be formed on the pipes, therefore they are recommended to inspire.

Arrangement of natural ventilation

Such a system is ideal for small rooms. Its installation does not require special efforts and significant financial costs. Among its advantages also distinguish such indicators as: reliability, low price, durability, the possibility of combining with artificial air circulation with an air conditioner or fan, as well as preservation of performance in the absence of electricity.

Natural Air Circulation Technology

The installation process is not characterized by consideration. All works everyone can do with their own hands without the help of specialists.

We will deal with how to make the ventilation of the cellar. For these works, we will need pipes from plastic or metal, also deflectors and clamps through which pipes will be carried out.

The dymeter of used ventkanalov affects the volume of passing air, and the speed of its movement depends on their height. Since air circulation depends on weather conditions, it is difficult to determine the exact parameters of the pipes.

For a cellar that has an area of \u200b\u200b40 sq. M. The pipes of diameters are 120 mm. However, to increase the speed of air flows, it is recommended to take pipes of a larger diameter.

The following instruction describes the system installation sequence.

1. In the case of the organization of ventilation at the construction stages, there should be no difficulties. It will only require an organization in the design of the houses of the holes suitable for pipe diameter.
2. After that, the pipes in these openings are installed and fixed by mounting foam or cement.
3. Exhaust Ventkanal should be placed under the ceiling, as shown in the photo. The pipe itself is towers above the roof, half a meter from the top of the roof. The trimmed channel is fully in the room so that it is 500 mm between the outlet and the floor, and the inlet would be located above the ground at the half-meter level.

1. Since the condensate is formed in the supply tube, its end is equipped with a special moisture collector equipped with a tap for draining water.

Tip! If the decision on the organization of ventilation was made after the completion of construction, it will be necessary to break the channels for mounting pipes. For this, the foundation is filled, in which the holes are then done to install pipes. In this case, the exhaust vent ripples to the wall of the clamps, and the deflector prevents the penetration of precipitation on top of it.

Arrangement of forced ventilation

To enhance the air exchange and the maximum approximation of the microclimate to natural conditions, it is resorted to the use of artificial circulation. The principle of operation of this option is based on the motion of air to move by means of exposure to special devices ().

Installation of a forced system

The result of this scheme depends on the type of fan used.

Forced air circulation is carried out in the following ways.

• Automatic characterized by autonomy. System control is carried out by the sensors installed, because if necessary, it can turn off or turn on.
• Mechanical ventilation Provides for human intervention to enable and regulate fans. In this case, the regulation of air flows will be required with the help of valves, which is especially important in the cold season. Strong thrust can lead to fruit freezing.

Homemade forced ventilation cellar provides for the same location of pipes, as in the first version. A fan is installed in the exhaust pipe by which the air will move. Aside the outside of the air flow creates a whirlwind, providing fresh air intake outside.

Ventilation of the cellar must be as efficient as possible. Over how to do this, every owner of the private house is conceived, especially living in the village.

Only the correctly equipped supply-exhaust ventilation in the underground storage of the private building will allow you to maintain a freshly broken harvest for a long period of time.

If you cannot take care of the ventilation system in a timely manner, then only a photo will remain in memory of the fruit stored there and vegetables.

Such a system is needed in order to make a comfortable environment for storing the harvest and constantly maintain the required temperature and humidity.

With its arrangement, it is necessary to take into account many factors and it is necessary to calculate everything and make it right.

There is nothing complicated here, which means that the cellar ventilation is with their own hands, with the presence of the necessary material and the tool, it can be arranged by each.

Features of ventilation systems

Any ventilation in the cellar under the house can be only two species, namely: natural and mixed-combined.

And the one, and the other ventilation scheme (if to do it correctly) allows for a long time to store a fresh harvest.

Before you start making the installation of the ventilation system in the cellar, the corresponding calculations should be made.

First, it will be necessary to calculate the space area and the required section of the ventilation channel. To do this, you will have to take advantage of some special formulas.

As a rule, for each square meter of the cellar, the necessary section of the duct should be at least 25 square centimeters.

It will not be superfluous to know the air flow.

It should be remembered that excessive ventilation of the cellar space can negatively affect the crop stored there, so the influx and outflow of air should be done within the limits of permissible parameters.

Also, the ventilation device for the cellar of the private house involves the presence of good waterproofing.

In addition, in the case when the cellar is an integral part of the whole house and has small size, it will be advisable if the supplied-exhaust system will be equipped directly in the base part of the foundation.

The video below shows how to make the ventilation of the cellar with your own hands.

In such a cellar, special inventories should be made, which, when decaying the temperature on the street, closes with the help of a vet, to protect against excessive humidity.

In the case when the cellar occupies a large area and has sufficiently high ceilings, some unnotes will not be enough to ensure normal air circulation all year round.

It is necessary that the natural ventilation of the cellar will be provided, which will make the optimal microclimate indoor.

This natural system is done personally quite simple. Her principle of operation is mainly based on the temperature difference in the basement and on the street.

In order to do it, it is only necessary to mount the supply-exhaust channels, which will ensure efficient air exchange in the basement.

You can see such a ventilation system in the cellar in the video.

Natural ventilation device

Making such ventilation is simple enough and quickly. To work, you will need two pieces of PVC pipes of the corresponding length with a cross section, which must be correctly calculated.

They will be needed to make the supplied and exhaust channels in the basement itself. One piece of plastic pipe should be mounted on a height of about half a meter from the soil level.

It will execute the role of the supply canal.

The second piece of the pipe is installed at the opposite end of the cellar under the upper overlap. It will be a hood.

This diagram of the supply and exhaust ventilation will provide the necessary circulation of air masses throughout the space.

It is worth noting that for these purposes it is impossible to use pipes from asbestos, as it can negatively affect health.

Also equip the air ducts and in the form of square channels. For this, the oven boards will be required, the thickness of which should be at least forty millimeters.

They must be easily adjusted to each other. When installing such a system, it is necessary that its inlet part is slightly above exhaust.

To prevent the formation of condensate in such a system, it is necessary to insulate its exhaust part.

Also, each channel individually should be protected by a special grid from penetration into rodents.

In order to adjust the flow of incoming air if necessary, the damper should be mounted on the supply part. You can see such a system in the work on the presented photos and videos.

Forced ventilation device

In the summer, especially when the window is severe heat, natural ventilation basement of a private house can lose its effectiveness.

In this case, the exit from the situation can be the arrangement of flow-exhaust ventilation of forced type.

The diagram of its device is a bit more complicated than a natural type of ventilation scheme, but with the task of making it on its own - each can cope.

Before equipping ventilation in the forced type cellar, all the necessary calculations should be made, make a phased work plan and prepare for work the required material and tool.

The main element in this case will be an electric fan, and low-power is suitable.

In this case, it is also necessary to install two pipes in opposite angles for a complete analogy with a natural basement ventilation system.

You can connect the fan to the network along the simplest scheme, however it is recommended that it is powered by a low voltage source.

Such a forced ventilation system will provide an opportunity to adjust indoors not only the temperature, but if necessary and humidity.

To learn more about the device forced ventilation in the cellar in the presented photos and videos.

On the video below it is described what forced ventilation.

There is another way to create forcibly ventilation without the use of electric current.

To do this, get the deflectors. This universal device is mounted at the top of the exhaust pipe.

In its work, it uses wind strength, at the expense of which it creates a vacuum in the air within the entire ventilation system.

This allows you to create the so-called surplus craving, which also performs the necessary air exchange.

You can also use special mini-turbines that work on a similar principle as deflectors.

Capturing the forced ventilation system, it should be remembered that it will interfere with natural air circulation.

Control of the ventilation system

Make it is easy and all that will be needed is the boxes of matches. The cellar itself should be descended, to light one of the matches, and then watch how quickly it goes out.

If the flame on the match goes out almost instantly, then it is necessary to run forced ventilation, since in this case an increased carbon dioxide content is observed.

In addition, the temperature itself is controlled inside the cellar in the thermometer, which should be hung on the wall.

Only the correct ventilation of the cellar can provide the necessary air parameters.

From time to time, any ventilation system requires inspection and, if necessary, clean.

It should be regularly controlled by the purity of both channels, and if they are placing a flare, it should be removed as accumulated.

Ventilation in the cellar plays a very important role, because in the absence of regular air flow in the room for storing fresh products, dampness will appear. To equip the hood in the basement is quite simple. And this can be done not only at one of the stages of construction, but also in the finished room.

What principle does the ventilation system work?

Before making ventilation in the cellar, examine the principle of its work. It is based on the laws of physics, which are based on when creating a scheme for ventilation arrangement. According to it, 2 holes should be provided to create ventilation. In one of them, fresh air flipped into the basement. Through the second hole, the air together with evaporation comes out of the cellar into the street. The scheme is quite simple, however, for greater efficiency, it is necessary to carry pipes to the holes. In addition, the system is very strongly affected by the location of pipes for tributary and air pulling, as well as their level above the surface of the soil.

Ventilation pipes should be placed directly in the basement walls. Also, the housings are often installed in the garage cellar. In the latter case, the pipes should pass through the room and excreted above the roof of the construction. A very important factor in creating a scheme is the height of the pipe mounting from the cellar to the street. With incorrect calculation of the hood for the cellar, it will suck too much cold air, which will adversely affect the storage time of fresh vegetables. Experts also do not advise to make too small holes for pipe supply, as this will not fully remove evaporation, which will lead to the loss of products.

On how to make a hood in the cellar, there are a lot of opinions and tips. Let's study the most useful recommendations regarding the creation of the circuit and directly the air circulation system itself for the basement. Many experts advise to provide a ventilation system during the construction of the basement. At this time, on the walls of the room, you can leave holes in which the pipes will be installed in the future. To then not choose the appropriate place to lay the channels, we advise you to include the exhaust system into the original basement project.

Pipes that are used to circulate air must have the same size. If the room is distinguished by high humidity, the pipe for the exhaust can be taken with a diameter of a little more than that of the suction. One of the main rules is not to do on the contrary, otherwise it will entail the air delay in the room. Another useful advice is not to place both pipes. In such a situation, the basement will not be fully ventilated. It is best to put the channels in opposite angles so that the air passes through the entire room. An exhaust hole must be installed under the basement ceiling. This is due to the fact that the spent hot air will rapidly reach the top. This position of the pipe contributes to the uninterrupted air purification without the slightest stories under the ceiling.

The exhaust pipe should rise by 1.5 m above the skate. This will provide sufficient air craving.

For the arrangement of the exhaust system, plastic pipes are most often used. Ventilation of the cellar in the garage should be placed using pipes with minima turns and bends. It is best that the channels are perfectly smooth and straight. In addition, each of the channels should have the same diameter in its entire length. Before making ventilation in the basement, put special dampers on the pipes. Their presence is especially important in winter, when you need to independently adjust the supply and outflow of the air. With vertical headings of pipes, they will need to be protected from rain and snow. It will be possible to make a decorative metal lining in the form of an umbrella.

Types of exhaust systems - Natural or forced?

Also before making ventilation in the basement, decide on the system type. It can be natural or forced. Pick up the most suitable option can be based on the planning and volume of the basement. The first type of extractor is based on a small temperature difference and pressure inside and outside the room. On the efficiency of ventilation strongly affects the location of the pipes. The air suction hole should be at an altitude of about 30 cm from the floor, and the hole for pulling - at a distance of 20 cm below the ceiling. It is impossible to leave the latter below, since otherwise the ceiling will very quickly start cheat. Such a system will not be enough to arrange large basement areas, which consist of several rooms.

The second type ventilation also consists of pipes, but they need to install special fans, forcibly forcing air to circulate indoors. The simplest system includes the installation of the fan only in the exhaust channel. In this case, the room is artificially created a discharge that helps quickly draw air through the hole for the tributary. The power of the fan must be selected taking into account the area of \u200b\u200bthe cellar. Often the owners of housing come a little differently. They put fans on both channels. This is especially important for basements with several small rooms.

Installation of ventilation - detailed algorithm

Almost every inexperienced person wonders as correct in the cellar. To do this, you need to act on a specific algorithm:

1. 1. If the ventilation system is mounted after the basement construction, then in its ceiling you need to do a hole for air circulation.
2. 2. After that, the pipe designed for the exhaust is lowered through the hole.
3. 3. Purpise the ceiling under the surface of no more than 15-20 cm below it.
4. 4. Outside the pipe should be raised by 1.5-meter height over the soil or above the roof.
5. 5. In the corner of the ceiling, on the contrary, it is also necessary to do a hole and stretch into it a pipe for air inflows. Place it at a height of not lower than 20 cm from the floor.
6. 6. Outside the supply tube should not be too high. If it passes through the ceiling, then its upper part should be located not higher than 25 cm above the surface.
7. 7. If the tributary tube is displayed through the wall, then it will be necessary to wear a deflector or grille.
8. 8. If the installation of ventilation is performed inside the residential building with a furnace or fireplace, then the pipe for the drawing rises near the chimney. It contributes to a more active dyeing of the basement due to the difference in temperature.
9. 9. At the end of the installation you need to install control dampers on pipes. They will allow you to put the right amount of air into the room.

After installing the system, it will be necessary to check it on the presence of thrust. To ensure the normal air pressure on the entrance, a paper sheet is applied to the supply tube. If it starts trembling, it means that the air actively enters the inside of the room. The second way is to arson paper in the bucket inside the basement. In the direction of smoke, it will be possible to determine where the air is moving as quickly.

What you need to do to maintain microclimate indoors

Having considered how to make ventilation properly, we suggest to deal with further premises care measures. To maintain a comfortable microclimate in the basement, you need to perform certain procedures from time to time. So, to contribute to a decrease in humidity in the room, regularly ventilate it. In the summer, be sure to open the doors and hatches of the room once a week, as well as dampers on the pipes. The hot wind falling inside the floor, the walls and the basement ceiling.

Often the owners face situations when they need to quickly increase the humidity in the room. To do this, you need to spray it with water from a conventional spacing. You can also install in the basement a container with wet sand or sawdust. If you needed to dry the basement, then first of all you need to make all the racks and other furniture from it. All racks need to dry in a natural way in direct sunlight. Luches and door open the laser and turn on the fan. In such a state, the room should be at least 3 days. After this, proceed directly to the drying of the basement.

To get rid of moisture indoors, bring and leave in it several boxes with a negated lime or a large cook salt. These substances absorb moisture very quickly. In addition, they effectively disinfect the surface of the room and the air in it. An older method is to use the candle. Install and secure it next to the exhaust hole. Light a candle and wait a couple of days. The flame forms the best craving, due to which more recycled raw air will be out.

Another way to quickly and efficient drying is the use of brazier. It is easy to make it with your own hands using the usual metal bucket. To begin, do several holes in the container, then fill it with birch wood. Next lit logs and leave no less than 12 hours. During this time, the room will quickly warm up, after which you can keep our products in it without fear for their loss.

Moor protection cellar processing - Important procedure for freshness of products

On one drying of the premises, the cellar care measures do not end. To extend the period of preservation of the cellar without moisture, the surface of the floor and walls must be coated with waterproofing compositions. If the walls in the room are erected from concrete, use the impregnation of deep penetration. It must be applied in several layers, each of which will be seeded inside the plates and close the holes and cracks in them.

Sometimes the dried cellar is covered with rubberoid. It is considered a good insulator, however, to use the wall and the floor should be perfectly smooth. To do this, at first a mastic is applied on the surface, which you need to heat, after which the insulator itself is put on top.

Environmentally friendly material for waterproofing is clay. It should be very fat, otherwise there will be no benefit from its use. Before applying the material, the basement floor must be postponed with stones, on top of which shredded with sand clay. The layer should be approximately 10-12 cm. After applying clay, it is necessary to ravage between the stones, then you need to pour a layer from the sand of large fractions from above. It will also be required to ravibly. The only disadvantage of this method is the long-term drying of the floor. On average, it takes about 30-40 days.

Dye basement with household appliances - fan or heater?

Get rid of excess moisture in the product storage room can also be used by household heaters and fans. In the first case, "windy" and convector models of heaters are suitable. To dry the surfaces of the walls and floor, install the heater in the center of the room. Thus, the device will evenly distribute heat, and none of the angles will remain raw. No need to forget that this drying method takes a lot of time. In addition, you will have a lot to spend on the payment of electricity.

Often the owners of basements use powerful steam generators. Due to its radiation, the product storage room dries very quickly.As a result, you spend a little less, because drying will take less time. Due to the effectiveness of this method, it is often used even in basements survived by the flood.

To get rid of moisture with a fan, the device must be put in the center of the room and turn on. Full drying in this way will take at least 4 days. Often the owners of the cellar helps and the ordinary old burzhuyka. In such cases, the stove tank is removed to the hood of the basement. Turn the burzhuyka will have at least 5 days until the basement surfaces are completely drying. If there is no exhaust hole in the cellar, then this method is not suitable.

Grown fruits and vegetables must be kept until the next season to provide themselves with products for all year round. Requires dry and cool room. Only the cellar made in accordance with all the requirements will cope with such a task.

Why do I need ventilation?

For storage of vegetables, ventilation in the cellar is installed. The scheme should provide operation by creating a temperature difference outside and inside. Warm air flows go up, and cold come from below. How to make ventilation in the basement and cellar? This requires the creation of devices for the influx of dry and outflow of wet air, for which the pipes are usually used.

Increased dampness is not suitable for cellars or basement. It should be removed in them primarily by creating a tightness and prevention of leaks in underground communications. The more water basement, the higher the loss of products during storage. In addition, the crude cellar has a negative impact on the microclimate in the house.

Natural and forced ventilation

In order to adjust air humidity, ventilation in the cellar has long invented. The detailed scheme includes natural and forced, although they can exist and separately.

The first version of the system of natural influx and drawing does not require energy costs and is very popular. No special professionalism and skills are required, so that the cellar ventilation was made with their own hands. How to make it, decide while designing the construction. In any building provide inventory.

This is done simply and is an effective solution that does not require costs. From rodents they are closed with metal grids, and, if necessary, covered.

How to equip ventilation?

The ventilation of the cellar or the basement is done in the premises of large sizes, with a ceiling height of more than 2 m. The exhaust box is included in the cellar under the ceiling, and goes through the roof of the house, garage, shed, because the warm and humid air accumulates upstairs and it is necessary to remove it.

Accommodation of air ducts

Pipes are best located next to the fireplace or stove. Then the thrust will be much larger. The supply tube also goes to the roof, but its lower part is located in the opposite corner. The thrust will be better if the pipe is shorter or has a larger diameter. It is made by a 50-60 cm high from the lower level of the room. Then cold air from the outside will go to the lower part of the cellar. If the pipes are located nearby, there will be a limited area, and the rest will be raw. They should have as many turns and bends as possible. The air ducts assemble dampers to regulate heat exchange and humidity. How should the cellar ventilation be equipped with their own hands? Installation circuit is shown in the image below.

Dimensions of pipes

Dimensions of pipes are determined by the gabarites of the cellar or basement. On 1 m 2 of the area should account for 26 cm 2 of the cross section of the air duct. Then for placing an area of \u200b\u200b6x8 m and a height of 2 m, the diameter of the boxes will be 40 cm. In addition, with an increase in the depth of the cellar, the pipe cross section should increase. For a small basement, one duct can be enough. It can be made of wood and divided into two parts - supply and exhaust. The presence of two pipes for it will also be an effective solution. From above, they are closed by visors from rainfall.

Water pairs passing through the exhaust pipe, winter freeze, reducing the passage area. It is trying to insulate, especially in places of frosting grounds and exit to the roof. It will be better if you wear another pipe or casing with a gasket between them heat insulation, for example, mineral wool. The budget option will be the use of asbestos-cement pipe, which has the necessary strength and low thermal conductivity. Also, the moisture is less condensed. During the cold, the passage of the exhaust pipe is cleaned in order to avoid clogging. For better thrust it is made as high as possible.

Forced ventilation can be made without additional energy consumption. For this, a deflector is installed on the exhaust pipe from above. When wind appears inside the pipe, there is a vacuum contributing to additional air exchange.

How to control air circulation in the basement?

Forced cellar ventilation is installed in addition to natural if the latter cannot fully fulfill its functions.

The system is checked on the quality of the work of the lifting matches to the bottom hole of the hood. If it does not burn, it means that there is no circulation in the cellar and a lot of carbon dioxide. It is possible to reduce its quantity if you install the supply tube with a large diameter. The presence of flaps on air ducts allows you to adjust the intensity of the air exchange and the temperature regime in the room. In this case, there should be no stagnation or its healing due to intense circulation. An indicator of the wrong exhaust organization is the presence of condensate on the walls.

High-quality temperature adjustment is provided only in the presence of thermal insulation. In addition, condensate accumulates without it on the concrete ceiling and the walls. The budget decision will be the lining of foam sheets. At the same time, attention should be paid to the joints where moisture may form.

For ventilation arrangement, you will need the following:

• pVC pipes;
• clamps;
• bolts, nuts.

Light tubes are securely held on the walls. If they are made of metal, there is a better welding and fastening in the walls. Wood air ducts are processed by special compositions from rotting.

In the exhaust pipe (20-30 cm from the bottom end) the hole for draining condensate is made. It is joined by a nozzle associated with a container for collecting fluid.

Requirements for the storage conditions of products in the cellar

In order for the premises to meet the functional requirements, it must be the following conditions:

1. Full blackout. There should be no windows inside, and artificial lighting is used only when visiting the room.
2. The temperature in the warm period of the year should be lower than outside.
3. The moisture content in the air of the cellar should not exceed 90%.
4. Permanent air exchange is created by the right natural air circulation in the cellar. It is necessary to prevent stagnation of air, but at the same time unnecessarily not heated or cool it.

How ventilation is done in the cellar with their own hands. Installation scheme

If the basement is already blocked, the holes for mounting the air ducts are made on the opposite corners at the rate of 26 cm 2 / m 2 area. The exhaust air duct lowers through the hole inside that the lower end is under the most ceiling, with an indent of no more than 100-150 mm. Its upper part is removed through the roof at a height of 150 cm. The trim duct is carried out into another hole at a distance of 20-25 cm from the basement floor. Then the cracks are closed with cement mortar.

Ventilation in the cellar: device, microclimate maintenance scheme

1. Periodic ventilation. In the warm period, as well as before laying a vegetable, all that can be: hatches, doors and dampers on pipes. As a result, the cellar is dried.
2. When the room was strongly impregnated with moisture, it is removed from it all the tree and dried it under the sun. The cellar can be additionally blocked by fans 3-5 days before the autumn laying.
3. Excessive moisture is removed if the cellar put the container with a negated lime. If you ignite the candle in front of the exhaust pipe, the thrust will increase and the ventilation will improve. Effective is the use of electric heaters or home in the middle of the cellar.

After drying the wall and the ceiling covered the impregnation of deep penetration, which is applied by layers. A waterproof surface is formed, passing only air and steam.

When the extractor works normally, because the ventilation in the cellar is made, the scheme provides usual ventilation. It is enough to create the desired microclimate.

How to make a hood in the garage cellar? Specialist advice are reduced to the following:

1. In the cold period, the hood has to cover so as not to cool the basement. At the same time, a lot of moisture is formed in it, which adversely affects the safety of products. To ventilate on the LAZ, a steel or wooden grille is placed and closes with old blankets and other rags. Warm air and couples go through the pores without forming a land. At the same time, dampness in the cellar decreases and vegetables are preserved better. Materials with low porosity for shelter are not suitable (synthetics, tarpaulin, film).
2. Necessary to cut the cellar is not recommended, as it negatively affects the safety of products. Sometimes it takes for this floor sprinkled with wet sawdust or sand.
3. It does not cope with its duties if the air temperature in the cellar and the outside is the same. Then the electrical fan is installed in the exhaust pipe, when the plot air is turned on, it is forcibly driven out of the room. High power for this is not required. An additional device should not interfere with natural air exchange. To do this, the diameter of the exhaust pipe is selected more calculated.

Conclusion

You can make a convenient room with optimal storage conditions of vegetables, if the natural ventilation in the cellar is equipped with their own hands. The scheme provides for the presence of two boxes - supply and exhaust, which must be correctly calculated and are established with the possibility of regulating passage sections.
