For storage of vegetables in the basement, the corresponding microclimate is needed, the temperature is 2 ... 5 ° C, humidity - up to 90% (year-round). The excess of these indicators leads to the formation of mold, rotten root and fruit. To remove the excess moisture and partial adjustment of the temperature mode, the ventilation of the cellar is used - naturally or forced. How to make an underground storage vending correctly, read further.
In the basement rooms of private houses, it makes no sense to arrange forced hood. In most cases, the tasks assigned to solve natural ventilation in the cellar. To organize such an air exchange, you need to understand which factors affect the microclimate inside the basement:
Reference. The relative mass of air molecules is 29 units, water vapor - only 18. Accordingly, the greater the moisture contains 1 cube of air, the more easier. Example: if you open the door in the winter cold balconyThe condensate will immediately appear on the ceiling (see photo above).
Now specifically about the ventilation device in a vegetable cellar. To organize a natural circulation of air flows, we use convection phenomenon. Action plan:
Cellar under residential house Or a garage, built without a project and outer waterproofing, can be very dying in winter. Such storages have to be dried in the summer - we will list the ways at the end of the publication.
To ventilate underground rooms, you can use 1 of 3 schemes:
One-tube ventilation system - Fresh air falls into the storage through the door The choice of option depends on the design of the basement, its location and other conditions. The system shown in the picture with 1 duct is applicable for cellars with a separate outlet to the street. How the scheme works in cold period of the year:
Important moment. With a single-pipe circuit, the vent ripal must be installed at maximum distance from entrance door, at the opposite wall. This ensures a full update. aerial premises.
Summer cellar ventilation scheme with outdoor pipe location The system of ventilation with two pipes is used in the cellars without a separate entrance - under private houses, garages and other economic buildings. Natural air circulation is organized similarly, only the influx is the second vertical channel descending to the floor itself. Cold outdoor air lowers at the intimidate duct, replacing gases leaving on the street.
Pipes are located in opposite corners of the repository and are displayed in two ways:
In the first case, the headband of the supply pipe is at the ground level, the exhaust mine is better raised to a height of 2 m (counting from the intake opening in the basement). If the building is surrounded by other buildings and withdraw the second channel now, the air duct is laid in the second way - on the roof. The end of the hood tube rises over the skate.
The layout of the ventilation channels and movements of air flows in the garage. Pretty pipe between the pit and the cellar can not be put Note. Manufacturers of finished cellars from plastic or concrete immediately provide for two-pipe ventilation. Channels come out vertically through the storage ceiling, the hatch closes tightly.
Active air exchange with forced motive is organized by a single-tube or two-pipe scheme, the fan is put on the exhaust channel. Ventilation operation can be automated by connecting the supercharger to the power grid through the thermostat. The device with the sensor turns off the fan when the temperature falls below the specified threshold. Look details on the video:
To equip the ventilation of the home cellar with your own hands, you need to find out the volume of the supply air, then determine the cross section of the ventkanalov. The number of inflows by calculating the weight of the stored vegetables:
Note. If automobile spare parts and tires are stored in the basement of the garage, then for ventilation there will be enough air exchange for 1 hour. That is, air mixture consumption is equal to the size of the room.
Knowing the amount of supply and exhaust air, make the calculation of the pipe cross section by the formula:
Example of calculation. The cellar is 400 kg of potatoes, the rest of the vegetables - 200 kg. Then the amount of inflow will be 3.5 x 4 + 7.5 x 2 \u003d 29 m³ / h. Determine the cross section of the pipe: F \u003d 29/3600 x 1 \u003d 0.008 m², through the formula of the circle area, calculate the diameter - 0.1 m \u003d 100 mm.
In the device of ventilation systems in apartments and private houses, galvanized, enameled and plastic PVC Channels. But for the cellars, the listed options are not suitable - the ducts from the galvanich quickly rust from moisture, and the enameled steel and PVC is expensive.
On the left in the photo - exhaust air duct from the tube of internal sewage, on the right - the inflow from the PVC pipeline Support and exhaust mine in basements are made from low-cost and moisture-resistant materials:
Addition. If the farm has a pipe of Ø100-150 mm from black steel, boldly use it when arranging an exhaust / tributary. Underground channel of the channel should be covered bituminous masticThe outdoor part is painted 2 times with any stack of paint, for example, the PF or NC brand.
The most profitable and convenient option is option - sewage pipe For ventilation from gray polypropylene. The material is cheap, lightweight, resistant to any chemical influences. Additional plus - the presence of finished shaped elements connected with straight areas into the fool. The air duct is attached to the walls with regular clamps.
Asbestos pipes benefit from the sewer time, but losing in the convenience of installation. Pipelines are pretty heavy, there are no shaped parts - the channel turns will have to be made from the girlfriend. Short review Various Ventkanalov Look at the video:
Scheme with gasket air ducts through the roof of summer kitchen Note. A single-tube extractor works well in storage facilities with top laser. Heated air masses are collected under an even horizontal ceiling, then they are fond of ventilation.
We offer several specific tips, how to make ventilation with two pipes:
The difference between the heights of the ducts of the big role does not play. The cutting channel slice rises to the minimum height (up to 1 m), the hood tube is derived from the aerodynamic shadow of the building so that stable natural traction arose. If you cannot raise the air duct, put the deflector - thrust instead of the umbrella.
With the arrival of warming, climatic conditions change - street temperatures It becomes higher, warm light air does not wish to independently drop into the cellar. Accordingly, the cold air masses do not leave the room, natural ventilation basement does not work, the moisture is not deleted.
How can the cellar can be dried:
Council. To be concrete Walls The fungus did not appear, after drying, treat the surface with a solution with a hawned lime or another antiseptic.
For summer ventilation, the housing cellars often use folk method - Just open all the hatches and doors to the basement. The method is ineffective, because heavy cold air does not seek to go out. Such a drying will take 1-2 weeks depending on the humidity indoors.
Ventilation basement or cellar is an important component of the competent operation of the room. Without the air exchange system, dampness is actively applied, excessive moisture is formed. In the cellars and basements are not only conservation, but also the reserves of vegetables, fruits, which are characteristic of breathing. The deficiency of the inflow of fresh air and the outflow of wet invariably leads to the accumulation of condensate.
During the construction of the base and the foundation, errors in terms of the device of the waterproofing layer are often allowed. In this case, the walls can accumulate dampness from the external space in their structure, absorb it from the soil. Level all listed omissions and unwanted manifestations are quite simple - to organize effective ventilation cellar or basement of an apartment building, for example.
Show all
Almost all modern private houses are built with the basement. This is one of the most effective ways to obtain several tens of square meters. useful Square without prejudice to the main housing. Here it is customized to equip sports halls, saunas, storage rooms and places for saving products. Even in the 21st century, most basements are used as cellars.
With their arrangement, it is necessary to adhere to certain recommendations:
The key point is high-quality ventilation basement and the presence of an appropriate system in principle. Effective air exchange will allow not only to store products much longer, but also eliminates the danger of molding and fungus, which often happens in high humidity. Functional ventilation of the cellar is an important component required to form optimal storage conditions of vegetables, fruits and other products.
The principle of system operation is built on basic laws of physics. Attentively, looking at the ventilation scheme in the cellar, you can stating the fact that it is located extremely simple, but at the same time reliably.
To organize a full-fledged system, it is enough to provide for the basement room 2 holes for ventilation. One of them is necessary for removal from the premises of extra evaporation and air, and the second to ensure the influx of pure and fresh oxygen. To ensure optimal efficiency, such a system requires two pipes, supply and exhaust.
Important condition for high-quality ventilation work in the cellar - correct location Air ducts, especially with regard to the placement of them above the level of soil.
Ventilation in the cellar under the house
No less responsible stage - installation of pipes on optimal height From the floor and subsequent withdrawal them into the external space. Incorrectly placed air ducts can bring too much air volume, which is extremely undesirable for fresh products and vegetables stored on the shelves. Too small diameter of the pipes will not allow you to quickly remove the edge air masses from the room.
The correct ventilation of the cellar involves thorough preparations, the development of design documentation and the study of recommendations on installation work:
In any case, the pipe located outside must be able to warm up, which will help to avoid the formation of condensate on the air duct walls in the cold.
A properly organized ventilation system is complemented by dampers by which you can adjust the supply and output volume, which is very relevant to maintain the optimal microclimate.
Before making ventilation in the cellar, you need to decide on the type of system that will be equipped in the room. It can be either forced or natural. The choice in favor of this or that option is determined by the peculiar planning features, its total area.
Using fan in the system
The main feature of such a ventilation system is the automatic feed and removal of air, which is achieved due to the fans located in the pipes. Its work does not depend on weather popsicles and external factors. In very simple version It is enough to place the fan at the exhaust duct. Thanks to this design in the room in a few minutes, artificially discharged air is formed, which is actively excreted into the external space.
For large basements with a complex architecture, it makes sense to set 1 fan and on exhaust, and on the trimmed channel. Naturally, without the help of a specialist who can prompt optimal solutions for the agreed and uniform conclusion and the flow of oxygen, not to do.
Forced cellar ventilation in the garage
The principle of natural ventilation is based on physical laws. The temperature and pressure indoors are different. The effectiveness of such a system depends on the competent placement of air ducts. The exhaust hole should be located 10-20 cm below the ceiling zone, and the intake - 25-30 cm from the floor.
For a small basement from residential country house This is quite enough, and in all other cases it is better to resort to the forced system.
So how to make ventilation in the basement? - The task of paramount importance is to choose the pipes of the required diameter. On average, 26 cm 2 air duct space is provided for the "square" of the cellar. If we are talking about a small square room, the dimensions of which are 3 x 3 m, the diameter of the pipe is calculated in such a sequence.
S. \u003d 3 x 3 \u003d 9m 2 -total basement area
T \u003d 9 x 26 \u003d 234 cm 2
The radius of the air duct is calculated by the formula:
R. = √ (T./ n) \u003d√ (234/3.14) ≈ 8.6 cm
Pipe diameter (under the influx):
D.p.≈ 170 mm.
Specialists advise to stop at the Pipe version with a stock of 15% for the exhaust channel. Respectively:
D.in. \u003d DP. + 15% \u003d 170 + 26 \u003d 196 mm.
Before installing all items, it is necessary to make calculations. Only in this case, the system will provide optimal conditions in the room.
After completing the preparatory activities, you can proceed directly to the installation of the system. There are rules that should be accounted for, regardless of what air exchange is a natural or compulsive.
Step-by-step instructions How to make ventilation in the cellar:
Ventilation in the cellar begins with the selection of material, the installation in this case will be carried out using asbestos and plastic pipes. In asbestos, we do two holes, one in each pipe (for placing in these holes of plastic pipes). The holes should be equal to the diameter of plastic pipes.
To do the holes, use a drill or screwdriver.
Next we produce the installation of pipes. At the bottom tube will be influxed, and on the top, respectively, the outflow. Pipe for outflow is mounted at a distance of at least 1.5 m. Above the ground surface or roof. And the supply at a distance of 20 to 50 cm. Above the surface.
Pipes made of plastic we put into the room, while the pipe is undervaluable to the far corner of the basement. The distance from the floor is left by the same-20-50 cm. As for the exhaust pipe, it is better to mount it as high as possible to the ceiling as possible, since, there is the warmer air and so it will be easier to remove it.

Cellar Depth 3.5 meters Ventilation System
To support the optimal microclimate in such a closed space, it is necessary to observe a specific sequence of actions.
The automated installation is much easier to maintain the optimal microclimate in space. If necessary, it can be promptly adjusted at its own discretion.
An important aspect of ventilation events is the drying of the cellar. Experts allocate several effective ways to eliminate excess moisture. It is better to spend them in the summer, when there are no products, vegetables and fruits in the room. The hatches, holes and valves are fully open and the space in this form leaves no less than 3-4 days. (Effectively with warm, dry weather) We will also tell you about several forced drying options.
In 80% of cases to dry the room, it is enough to restrict ourselves to installing a small box with a large salt or lime in the sizes. Their main feature is a hygroscopic structure, thanks to which they actively absorb unwanted moisture from the surrounding space.
Household fans are in every residential building. They effectively eliminate excess moisture. The device itself is placed in the central part of the basement and leave it on for 3-4 days. Previously all hatches and valves open completely.
If you have already built a cellar, but the condensate is constantly accumulated or the temperature increases, you may have incorrectly equipped the ventilation system and the influx of fresh air into the room is broken. Hood need to be thought out at the construction stage, as it will be more difficult to correct the situation.
From this article, you will learn how to make ventilation in the cellar and what works need to be carried out for high-quality air ventilation.
Air circulation in the underground storage can be provided with natural or artificial way. In the first case, the air enters through special holes, and in the second - with the help of fans (Figure 1).
The easiest, inexpensive, but at the same time, an effective way of airing is considered a sub-exhaust system. For its arrangement at different levels, two pipes are installed, the ends of which are removed. Through one of the premises, warm air is derived, and the other - the cool one comes. Next, we consider it more detailed how to equip various systems ventilation in basements.
Many owners of household plots believe that it makes sense to equip any extract in the basement. There is also an erroneous opinion that the presence of holes in the walls or roof of the repository will disturb the stable microclimate. In fact, everything happens on the contrary.
Figure 1. Principle of operation of drawing in basements In the residential premises, the temperature is too high for storing fresh vegetables and billets in banks, and on the street (winter) is too cold. In the underground storage, provided proper ventilation, Not only stable temperature is maintained, but the optimal for storage of vegetables humidity. It is with this task that a high-quality hood is successfully coping, through which warm air is derived, and a moderate amount of fresh oxygen is received.
For small cellars there will be enough one or more holes in the walls derived from the tube. However, if the repository is quite large, it is better to equip the supply and exhaust system that will effectively cope with the support of the microclimate.
Note: In large industrial storage facilities, special fans are installed, which provide a permanent and uniform influx of fresh air. However, such systems are too expensive, and it is economically unprofitable to use them in the household economy.
To determine how many channels need for your basement, you need to carry out some calculations. First, the area of \u200b\u200bthe room is calculated, multiplying the width for the length. Secondly, it should be borne in mind that on each square meter of the square it is necessary to 26 square centimeters of the exhaust channel. For example, if the cellar area is 6 square meters, this indicator must be multiplied by 26. The resulting number (156 square centimeters) will mean the total area of \u200b\u200bthe ventilation holes. To determine which diameter is optimal, you need to highlight the square root of this number, divided by the number Pi. In our example, this indicator will be 14 cm. However, for better removal of warm air and the inflow of fresh, this indicator can be independently increased by 10-15%.
After you spent all the necessary calculations and decided on a suitable diameter, you can proceed to the direct installation of the system.
Installation of drawing in the cellar is carried out like this:
After installation, the external parts it is desirable to cover with visors and lattices so that atmospheric precipitates do not fall inside. Check the traction intensity is very simple: it is enough to attach a sheet of paper to the suppress channel. If it hesitates intensively, then the influx of air into the room is good.
The system with one pipe is applicable only for small premisesSince the storage facilities of such an air flow will not be enough to support the optimal temperature and humidity.
To mount such an exhaust, you will need a pipe that is cut into two parts and insert the prepared channels into pre-prepared channels. In addition, you will need dampers or visors so that you can independently control the removal of warm air and the flow of fresh (Figure 2).
In case the channel is not displayed via the wall, but through the roof, it is also necessary to install visors that will protect inner space Premises from the penetration of rainwater.
As a rule, 34 cm diameter products are used as exhaust channels. However, if you fear that such an exhaust will not be enough, you can choose a larger diameter model.
When choosing, it is necessary to take into account the area of \u200b\u200bthe room. Not only the diameter of the pipes themselves will depend on this, but also their number. So, for small basements is sufficient one or two, and for large storages it will take the arrangement of a more extensive ventilation system.
If you have selected ventilation with a single channel, you should consider that in the basement still will still have to equip two air ducts. But, unlike the supply and exhaust system, they are not equipped in opposite parts of the room, but in parallel to each other.
Figure 2. Carving a single channel Each channel is installed on the damper that will help control the exchange of air. In this case, for the removal of warm air, it is enough to open one channel first, and then the other - for the receipt of fresh oxygen.
Forced system with two pipes is considered to be more practical and convenient. Despite the fact that it will require more effort to work for its arrangement, the finished design will be successfully operating with almost no human involvement. All you need is to periodically check the traction.
Consider more detailed how to properly equip such an extract in the home cellar with your own hands (Figure 3).
There are several ways to ensure forced ventilation using two pipes. The easiest is the easiest channels of the same diameter in opposite corners. At the same time, they should be installed at different levels so that warm air is effectively extended from the room, and the cool thing evenly flowed inside.
Also, the ventilation system can also be provided with special fans that will provide a constant air flow. However, in this case, it is necessary to provide special protection of technology from moisture. They can also be provided with special devices - deflectors that will capture air flows and provide more intense traction.
So that the microclimate in the cellar is stable at any time of the year, it is necessary not only to correctly carry out the installation of the system, but also to choose the pipe suitable for this purpose.
Figure 3. Principle of operation of drawing with two channels In most cases, the cellar in the household farms are small, and for them there are enough several pipes of diameters of 10-14 cm. However, when calculating their quantity, the storage area should be guided. For small rooms (about 6 square meters), it will be sufficient one inlet and one exhaust. But, if the room is more (for example, 15-20 squares), you will need two pairs. It must be borne in mind that on average, the square meter of the room should accounted for 26 square centimeters of the air duct.
When using a supply-exhaust ventilation system, the correct installation plays a key role.
For this, in opposite ends of the room make holes in the roof. Their diameter should coincide with the diameter of the pipes used. Next to one hole insert the exhaust pipe. It should be positioned so that the lower end is 15-20 cm from the ceiling, and the top performed over the soil at 70-80 cm.
The intuition is mounted in the opposite end of the room and installed almost above the floor (at 15-20 cm from the surface). Top, respectively, only a few centimeters lifted over the soil. The edges derived from outside, it is desirable to cover the visors so that rainwater does not fall into the room.
The natural ventilation of the cellar is considered simple, as such systems are easy to install, and many materials are not required for their arrangement. However, it should be borne in mind that providing a stable microclimate in the room will be more complicated than when using the supply and exhaust system. In addition, if the temperature indicators within the cellar and the outside will coincide, the air circulation may be minimal or completely absent.
Therefore, if you plan to store products in the basement, which requires a certain temperature, it is better to attach a little more effort and to equip the supplied system.
The principle of operation of natural ventilation is very simple and based on the difference in pressure and temperature inside and outside the repository. Through one pipe, located almost under the ceiling, warm air is removed from the basement, and in the other, which is almost above the floor, fresh oxygen comes.
However, it should be borne in mind that this method of ventilation is suitable only for small rooms. In the warehouses of a large area, the advantage should be made forced ventilation.
As mentioned above, there will be no materials for the installation of natural ventilation. In this case, you need to prepare two identical pipes (for mounting the system itself), as well as sheet metal or lattice to protect the system from rodents and precipitation.
Consider more detailed how the installation of such systems is carried out and what features should be considered when they are installed.
First of all, it should be noted that it is necessary to provide holes for laying ventilation channels at the construction stage. When the cellar is already built, spend necessary work It will be more difficult.
Natural ventilation is mounted as follows:
From above, they must be covered with visors, otherwise the rainwater will be able to freely enter the room. It is also desirable to install small lattices on the lower parts so that rodents do not penetrate the storage.
In fact, forced ventilation differs from the natural only in that fans are installed inside the pipes (ventilation channels), which provide a more intense influx and air lead (Figure 4).
The principle of the operation of forced ventilation is quite simple. In the simplest version, the fan is installed only on the exhaust pipe. Thus, a more active air movement is created through the supply hole.
IN large rooms It makes sense to install fans and exhaust, and at suction. In this case, it will be difficult to cope with the most and better turn to a specialist who will help to determine the right pipe diameter and fan power.
Since compulsory ventilation is considered more reliable and modern, it will be necessary for its arrangement. optional equipment. Of course, first of all, you need to prepare the required number of channels of a suitable diameter. After that, you should buy fans suitable size and power.
Figure 4. Basic elements of forced ventilation It is also necessary to provide waterproofing devices from moisture, which can enter the room outside or leak through the walls.
Forced ventilation is mounted a bit more complicated than natural. In order for you to independently carry out installation, we recommend using our step-by-step instructions.
Forced hood in the cellar are installed as follows:
The tops of the pipes protruding on the surface, you must be covered with visors. In the case of natural ventilation, this requirement is rather a recommendation, whereas for a forced type it must be observed, since rainwater can damage the fans and the entire system will break.
In the video, it is shown how it is better to equip natural ventilation in the basement.
If the ventilation system is designed and mounted correctly, you can not close the holes for the winter. However, it is completely dependent on climatic conditions. For example, if the temperature on the street drops below -10 degrees, you need to periodically cover the holes, since the temperature difference inside and outside will create a powerful thrust that will lead to a rapid storage supercool.
In very strong frosts, ventilation channels are better to completely close, and with a slight increase in temperature, you can briefly open for ventilation.
Modern market building materials Provides a wide selection of pipes that can be used as ventilation channels. When choosing, most often guided by personal preferences and financial capabilities.
Recently, most owners of the cellars choose pVC pipes or cement products. This is explained by the fact that such pipes are relatively inexpensively, are easily mounted, but at the same time they have resistance to fungi and differ in a long service life.
To ventilate the cellar is needed throughout the year, although some owners of underground storage facilities believe that winter time Ventilation is not needed. This is a common misconception, but the share of truth in it is still.
If it is very cold on the street (about -10-20 degrees), the difference in temperatures inside and outside becomes too large and the thrust in the ventilation channels is greatly increasing. If you do not close the holes in time, the cellar can quickly freeze, and fresh vegetables or billets will be ruined. Therefore, it is recommended to monitor the temperature in the room, and in severe frosts completely close the channels before warming.
Useful recommendations on the installation of the ventilation system you will find in the video.
Providing storage of products is closely related to the humidity of the surrounding air. When it is raised, depending on temperature conditions Perhaps either education is inlet or condensate.
To ensure the necessary indicators of humidity, adjusting the air exchange in the premises below the level of the ground, you can use several ventilation schemes. Natural ventilation is characterized by ease of manufacture and lack of energy costs, however, it is not able to provide optimal air exchange rates.
Forced ventilation in the cellar has a more complex device and depends on the availability of electricity, however, it ensures the necessary indicators of air humidity and the rate of its circulation at any time of the year.
The use of air ventilation located below the ground level is greater than 2 m is prerequisite For lack of mold, plumbing smell. To ensure the safety of products in the cellar, the following conditions must be ensured:
In addition to the conditions listed, the humidity control of the cellar or the basement room will eliminate the possibility of a short circuit of the electrical wiring and the occurrence of the fire.
This type of ventilation provides forced injection and removal of air from the basement facilities, for which the fan is used. Supply-exhaust scheme is used if the temperature is higher than the level of the Earth and in the cellar is almost the same. Depending on the size of the room and taking into account the loss, one fan is used, which is mounted in the exhaust air duct or several, with the placement of the second in the supply tube for injection of air. With the aim of right mounting Devices that provide influx or air hood for cellar should consider some principles set out below.
When installing a device that provides air circulation should exclude interference of the natural ventilation of the room, for which the diameter of the exhaust air pipe is taken by a slightly greater than the calculated value.
The fan is mounted on the exhaust air duct from the base of the basement so that the air mass subjugation is created during its operation. The ideal case is considered to create a vacuum effect, in which the inclusion of a device for eliminating the front air coincides with the influx of fresh through the supply tube, located in order to cover the larger area of \u200b\u200bthe diagonal.
When planning and implementing an electrical drive, it is necessary to use transformers and electrical equipment with a voltage not higher than 36 V. This is due to the fact that basements belong to the group of rooms with high humidity, and therefore, when violating this recommendation, electric shock is possible in the event of a breakdown on the fan.
To ensure the ventilation of the entire size of the room, the forced ventilation of the cellar must take into account the following principles of the correct installation of aircases.
The trim airbranch is a system of several pipes and a knee with an angle of 90 °, mounted in such a way as to provide a protrusion above the surface of the Earth within 30-40 cm. The lower end of the pipe must not reach the floor of the floor of the basement half meter, the rest of the pipe is uniformly fixed throughout the length with the help of clamps and self-tapping screws.
A billet from galvanized tin or PVC can be used as pipes, they provide the necessary air exchange characteristics with a small mass and comparative ease of installation.
The pipe diameter depends on the area of \u200b\u200bthe cellar, however, there are recommendations substantiated by specialists, which they say that for the premises no more than 40 m², the sufficient diameter of pipes for ensuring a complete air exchange for half an hour is 12 cm.
In the pipe or under the surface of the cap, the fan can be mounted, providing air injection, such a system is used in the case of weak air injection indoors associated with the wrong arrangement or installation of the pipeline.
Speaking over the ground level of the supply air pipeline is closed with a mesh, with small holes, the size of which eliminates entering the living organisms. A hood is mounted above the grid, to ensure the protection of the system from precipitation.
The supply tube can be equipped with filtering elements that can be cleaned by air.
To ensure air removal, it is important to correctly select a fan in power, since too fast air circulation, especially in summer period Time threatens drafts.
In addition, entering outside the warm air will be discharged for a short period of time, not soying to normalize the microclimate of the room. Selecting the fan of the required power, you should consider the length of the pipeline, losses along the length of the channel, the area of \u200b\u200bthe room.
The basic value of the pressure loss per square meter of the air canal is 2 cubic meters / hour from one m². The required fan performance is a product of a loss on the volume of ventilated space. However, taking into account losses in length and depending on the diameter of the pipes, it is better to choose a fan that has a reserve in terms of performance.
A portion of the exhaust pipeline, located in the cellar, is recorded not lower than one and a half meters from the floor level, must contain a condensate collection and diverting system and a fan that bulk air outwards.
The output tube of the exhaust pipeline must be mounted in such a way that its upper end spoke above the roof level by half. If there is a furnace in the house, the installation of the exhaust air pipe pipe is greatly simplified. However, in any case, in order to eliminate the formation of condensate, the protruding part of the pipe must be insulated in order to avoid accumulation of Inea winter of the year.
The outlet hole of the exhaust air duct by analogy with the intake must be closed with a grid and a cap.
Ensuring the safety of products in the cellar is closely related to the microclimate inside it. To ensure the circulation of air masses, the supply and exhaust ventilation schemes or the variant of their combination can be used. Described device types ventilation systems There are no dogma and an indigestion owner, putting a little smelting, can use the wind energy of the wind as a drive for the supply ventilation system.
Another version of the upgrade is to install automatic control systems for the basement microclimate. In any case, it is important to remember that the correct organization of air exchange in premises with limited air access will not only ensure the safety of the supplies, but also will prolong the service life.
