Cellar ventilation device with one and two pipes: an overview of important technical aspects

Scheme of the ventilation system and its features

The arrangement of natural aeration is possible only in small areas without partitions and large-sized racks. The presence of obstructions reduces the rate of circulation, making ventilation less effective.The same rule applies to the area of ​​​​the room, since the larger it is, the more difficult it is for the air flow to move through it. Therefore, to organize full-fledged ventilation in such buildings, forced-type systems based on the action of electrical energy are used.

Air flow pattern

The creation of a working model of ventilation of a natural type room is carried out according to clearly established rules regulated by SNiP. The influx of fresh air and the removal of exhaust air is carried out using 2 channels. The supply air duct is brought out 10-15 cm above the floor level, and the second one is under the very ceiling, retreating from it by 5-10 cm. Such an arrangement of pipes ensures the outflow of waste masses, and allows fresh air to freely enter the room.
From the outside, the supply air duct is mounted above the ground 30-40 cm above its level. The exhaust pipe is installed above the inlet by 25 cm or more

A similar arrangement makes it possible to achieve the necessary pressure difference and ensure full aeration inside the cellar.
Important! The higher the outlet pipe is installed, the greater will be the difference in pressure inside the room. Consequently, air masses will replace each other more often, removing excess moisture and preventing the spread of mold.

Natural ventilation in the cellar

We carry out calculations

Before starting any construction work, it is necessary to make appropriate measurements and draw up a drawing plan. The diameter of the pipes plays a decisive role in ensuring effective ventilation. It should be such that the amount of fresh air is sufficient to ensure an optimal microclimate in the basement.

The diameter of the pipes is determined in a fairly simple way. The number that determines the diametrical section of the pipes should be twice the number that expresses the area of ​​\u200b\u200bthe cellar. For example, if the area is 10 m², then the diameter pipes should be 20 cm. This is the simplest way to calculate. You can apply another one: 26 cm² of pipe area is calculated per square meter.

How to determine the pipe diameter?

The determining factor in the effectiveness of ventilation is the proportionality of the cross section of the duct to the area of ​​the room where it is installed. Calculating the required pipe size is easy.

Experts advise to adhere to the following rule in calculations: per 1 sq.m. basement needs 26 sq.cm. sections.

It turns out that for every centimeter of pipe diameter there are 13 square meters. see sections. Based on this, you can calculate the desired pipe diameter using the following formula:

(S cellar × 26) ÷ 13

For example, if the square of the basement is 8 sq.m., then it turns out that for the cellar it is necessary to purchase a pipe with a diameter of 16 cm.

(8×26) =208÷13=16 cm.

If single-pipe ventilation is installed in the cellar, then the diameter of the duct should be larger. In this case, it is recommended to use a pipe with a cross section of 17 cm for the basement of this area.

Types of ventilation systems

There are several types of ventilation systems. For example, for the required level of ventilation, you can use ready-made devices (forced ventilation, most often used for commercial structures) or duct yourself (natural ventilation in the cellar, used in a private house for own use).

Before embarking on the arrangement of the ventilation system, you need to determine which method suits you best. The first involves the presence of special equipment - a fan permanently fixed in the basement. For small home basements, as a rule, there is no need to install such units. But putting a small fan for a few days will be very useful - this way the room will be dried in a short time.

There is also a combined method, it combines the first two: it assumes the presence of air ducts, one of which is equipped with a small fan.

The first type of ventilation consists in the principle of supplying fresh air and removing stale air by installing two corresponding pipes. To install it, you need to carry out 2 shafts (supply and exhaust). Cellar ventilation with two pipes is quite effective, despite its apparent simplicity.

The assembly of these air ducts is carried out at opposite ends of the room, so as not to leave any part of the room unused. The greater the distance between the pipes, the better: it means that the maximum area will be covered. The supply shaft is mounted at the bottom of the wall, and the exhaust shaft is mounted in its upper part.

It is this arrangement of air ducts that is explained very simply. Cold air is heavier than warm air, so you need to supply it at the bottom so that, when heated, it rises up and out. In winter, when the air is colder and heavier, the ventilation process is even more accelerated, respectively, the air exchange increases.

It should be clarified that in a region with a constantly warm climate, this method is ineffective; for full ventilation of the basement, only a combined system should be used.

Combined ventilation in the cellar is universal and can be used in a region with any climate. Its essence is to install the same two pipes (supply and exhaust), but in addition you need to install a fan on the supply air duct. It increases the flow of air into the room, due to which its output becomes more intense.

The purchase of such a fan and its consumption of electricity will not be large financial costs.

Installation of a duct type fan

This type of fan may not have a high degree of performance, for this reason it can be powered from a minimal power supply. It is advisable to purchase an amplitude device that can provide a high level of efficiency.

A well-installed hood for the basement space perfectly manifests itself in the initial operational period.

So, the air in the cellar becomes humidified, but not very much, as a result of which food products do not lend themselves to any freezing, the temperature regime reaches 4 degrees.

As we said above, the installation of this type of hood can be done without the help of professionals and the use of complex tools, as well as special technical equipment. Simply put, everything can be done with your own hands, especially if you have the initial skills.

Basement ventilation products

You should think about how to ventilate the basement in a private house at the stage of laying the foundation.The simplest and cheapest option for ventilation in the basement of a house is a system of vents or simply holes in the basement. From the inside, the vents are covered with nets from rodents and insects. The photo shows basement ventilation in a private house with a ventilation system.

The efficiency of ventilation in the basement of a wooden or stone house will always depend on the strength and direction of the wind, and the temperature outside.

When organizing this type of air exchange, it is important to correctly calculate the area of ​​\u200b\u200bthe products, which is 1/400 of the basement area. Basement ventilation ducts

When calculating the area of ​​\u200b\u200bvents, one should also take into account:

• foundation depth;
• soil type and proximity of soil water;
• direction of prevailing winds;
• the amount of precipitation in different periods of the year;
• fluctuations in daily and annual temperatures.

The size of each hole is also regulated:

• diameter from 12.5 cm;
• area from 50 sq. cm.

In order for ventilation in the basement of a residential building to work effectively, a pair of holes on each side of the house will suffice.

Houses of complex configuration or located in the lowlands will have to be provided with enhanced ventilation: 2 air vents per 4 meters of foundation.

If a foundation is built under the inner walls, the air vents are also made in additional structures. Natural ventilation can be made controlled by installing vent valves. In winter, the dampers are closed, and in summer they are fully opened. In severe frosts, narrow gaps are left, since the draft is very strong and the basement will instantly cool down.

But such ventilation of the basement in a country house will not work if it is used as a storage for vegetables and fruits in winter.Air exchange will not be effective enough even with a large area of ​​\u200b\u200bthe house. For ventilation of the basement of an apartment building, air vents are used only as an additional means. The main one is chosen by the other pipe (supply and exhaust) ventilation system of the basement of a residential building.

How to calculate duct diameters

In order to equip the ventilation of a home cellar with your own hands, you need to find out the volume of supply air, then determine the cross section of the ventilation ducts. The amount of inflow is calculated by the weight of stored vegetables:

• for every 100 kg of potatoes we supply 3.5 m³ of air in 1 hour;
• 100 kg of carrots, onions and other vegetables - 7.5 m³/h.

Knowing the amount of supply and exhaust air, we calculate the pipe section according to the formula:

• F is the cross-sectional area of ​​the duct, expressed in m²;
• L is the volume of supplied air, m³/h;
• ʋ - the speed of the flow through the channel, with natural ventilation is taken equal to 1 m / s, no more;
• 3600 – conversion factor for time units (seconds/hours).

Calculation example. There are 400 kg of potatoes in the cellar, 200 kg of other vegetables. Then the volume of inflow will be 3.5 x 4 + 7.5 x 2 = 29 m³ / h. We determine the cross section of the pipe: F = 29 / 3600 x 1 = 0.008 m², through the circle area formula we calculate the diameter - 0.1 m = 100 mm.

How to make ventilation in the cellar

In order to correctly make the hood in the cellar with your own hands, it is recommended to use clear drawings and diagrams, this will help prevent the formation of condensate and save the crop from damage. Thanks to a chic assortment of building materials, it is possible to make the ventilation of the cellar in the garage with your own hands.

When there is a cellar under the garage, but there is no ventilation in it, various poisons and toxins released by the car will adversely affect the products. Flow-exhaust ventilation will help to solve this problem. This type of air exchange is possible even naturally or due to fans. As for the top of the pipe, it is displayed above the garage.

An accurate, correct exhaust scheme will help fix the problem in the shortest possible time. If you install a supply pipe, it is possible for the purified air to pass into the basement. The role of a pipe with an exhaust function in a garage with a cellar is the elimination of excessive moisture and toxic substances. The optimal output is a successful combination of exhaust and supply systems, which can be done in two ways:

1. Natural air exchange. This option is the most popular and common, you will need to install two pipes - supply and exhaust. The device functions perfectly, because the temperature indicator in the basement and outside is significantly different. The main disadvantage is that the hood does not function during the warm period. As for winter, it will have to be warmed up additionally.
2. Forced ventilation in the cellar. The proposed system is the best option of all existing ones. Thanks to this ventilation, it is possible to achieve an optimal microclimate, which is similar to the outdoor one. It helps to ensure ideal air exchange, as various units and fans are involved.

The arrangement of forced ventilation is carried out using electric fans that are added to the system. Making such a system with your own hands is very simple. The main advantage is the stabilization of temperature and humidity levels, despite the weather and season.

The scheme of the proposed device almost does not differ from natural ventilation. The algorithm of actions is simple: fastening pipes, installing a fan in an exhaust pipe. Instead of a fan, you can use a rotary diffuser-weather vane, it is installed on the top of the supply pipe, it functions from the wind. A deflector will help ensure good ventilation, which improves air exchange and rarefies the air.

The best and most advanced option is mechanized forced ventilation using a special monoblock. It installs the software that controls the modular system. The main problem and disadvantage is the high cost.

The scheme of proper ventilation of the cellar in the garage

To effectively use the cellar of the garage, it is important to ensure proper, full ventilation. To create natural ventilation, you can independently mount the system using plastic sewer pipes

In the process of work, it is worth observing some rules and tips:

• the ventilation scheme must contain a limited number of bends, pipe turns;
• it is necessary to insulate the exhaust pipe, otherwise condensation will appear;
• cover the entrance to the pipe with a cap to prevent precipitation;
• the entire length of the pipe must have the same diameter.

To equip natural ventilation, you should calculate the area of ​​\u200b\u200ball openings. The beginning of the supply pipe is 50 cm above the basement floor, it is taken out. As for the exhaust, it is fixed under the ceiling, pulled over the roof of the garage

It is important that the pipes are in opposite corners of the room

Having completed all the calculations, having determined the diameter section, it is necessary to determine the material of the pipes for the ventilation system.It is customary to use two main types, namely asbestos cement and low pressure polyethylene. Pipes made of asbestos cement are similar in structure to slate, which is why they are called slate pipes. Such raw materials are considered durable, strong and reliable.

Polyethylene pipes are not inferior in strength at all, but they have a much easier installation method, you do not have to use the services of professionals. The main condition is that they need to be soldered.

How to make ventilation in the cellar

Air circulation in the underground storage can be provided naturally or artificially. In the first case, air enters through special openings, and in the second - with the help of fans (Figure 1).

The most simple, inexpensive, but at the same time effective method of ventilation is the supply and exhaust system. For its arrangement, two pipes are installed at different levels, the ends of which are led out into the street. Warm air is exhausted through one of the rooms, and cool air enters through the other. Next, we will consider in more detail how to equip various ventilation systems in basements.

Why is a cellar ventilation system necessary?

Many owners of personal plots believe that it does not make sense to equip any kind of hood in the basement. There is also an erroneous opinion that the presence of holes in the walls or roof of the vault will disturb the stable microclimate. In fact, everything happens the other way around.

Figure 1. The principle of operation of the hood in the basement

In residential areas, the temperature is too high for storing fresh vegetables and preparations in jars, and it is too cold outside (in winter).In the underground storage, subject to proper ventilation, not only a stable temperature is maintained, but the humidity is optimal for storing vegetables. It is with this task that a high-quality hood successfully copes, through which warm air is removed and a moderate amount of fresh oxygen enters.

Calculation and device

For small cellars, one or more holes in the walls, brought out with pipes, will suffice. However, if the storage is large enough, it is better to equip the supply and exhaust system that will effectively cope with maintaining the microclimate.

To determine how many channels you need for your basement, you need to do some calculations. First, calculate the area of ​​\u200b\u200bthe room by multiplying the width by the length. Secondly, it should be taken into account that for each square meter area need 26 square centimeters of the exhaust channel. For example, if the cellar area is 6 square meters, this figure must be multiplied by 26. The resulting number (156 square centimeters) will mean the total area of ​​\u200b\u200bthe vents. To determine which diameter will be optimal, you need to take the square root of this number divided by the number Pi. In our example, this indicator will be 14 cm. However, for a better removal of warm air and fresh air inflow, this indicator can be independently increased by 10-15%.

Do-it-yourself installation

After you have made all the necessary calculations and decided on a suitable diameter, you can proceed with the direct installation of the system.

Installing the hood in the cellar is carried out as follows:

1. If the hood is mounted in an already finished storage, it is necessary to make several holes in the roof.
2. An exhaust pipe is inserted through one hole and fixed so that the lower edge is 10-15 cm below the ceiling, and the upper part protrudes 70-80 cm above the ground.
3. A hole is also made in the opposite corner and a supply pipe is inserted into it. It must be fixed in such a way that the lower edge does not reach the floor by 15-20 cm, and the upper one only protrudes 20-25 cm above the soil surface.

After installation, it is desirable to cover the outer parts with visors and gratings so that atmospheric precipitation does not get inside. Checking the draft intensity is very simple: just attach a sheet of paper to the supply channel. If it fluctuates intensively, then the air flow into the room is good.

The principle of operation of the natural system

The operation of a natural type ventilation system is based on a physical law. The difference in temperature inside the building and outside leads to the movement of the air flow and constant air exchange.

Warm air from the inside rushes to the ceiling, and its place is taken by cold air masses coming from the street.

The figure shows a diagram of the distribution of warm and cold air flow in a closed basement when using supply and exhaust ventilation

There are no windows or other openings in the basement that serve to inlet and outlet of the air flow. In order to organize a constant circulation of air in a closed room, it is necessary to equip it with exhaust and supply air ducts.

The first serves to remove warm stale air from the cellar, the second - provides fresh cold air flow from the street.

To ensure the optimum temperature in the room and good heat transfer, the ventilation ducts should be as far apart as possible.

The longer the distance that the air flow passes, the better and better the room is ventilated.

The supply and exhaust air ducts must be installed in such a way that the air has a place "where to roam". This will help create good air exchange in the room and the right temperature for stored products.

Checking the draft intensity is very simple: just attach a sheet of paper to the supply channel. If it fluctuates intensively, then the air flow into the room is good.

Rules for installing cellar ventilation in the house

• The supply pipe “enters” horizontally into that part of the foundation that is located above the ground level. Entering the room, the pipe turns 90 ° down and enters directly into the cellar, not reaching the floor 0.2-0.5 m. The inflow ventilation pipe should not have many bends and its diameter should be the same throughout the entire length of the duct.
• The entrance to the tributary, located not high from the ground, can be covered with snow in winter. To prevent this, you need to constantly clear the blockages (if any). Also, it must be closed with a grate through which rodents and birds cannot enter.
• The exhaust ventilation of the cellar in a private house runs inside the wall, along the kitchen or into a specially arranged channel.
• It is rational to arrange a cellar room under the kitchen, so the ventilation ducts will be combined.
• If it is planned to build a sufficiently large room that serves as a cellar, forced ventilation can be arranged in it. To do this, add an exhaust fan to the circuit, which will not allow stale and stale air to stagnate.

The principle of operation of the ventilation system in the cellar

Before you make your own ventilation system in the cellar, it is recommended to understand the principles of its operation. Everything is quite simple - warm and cold air flows in natural movement replace each other, pushing out of the room. All known structures are built in this way. Cold streams go down, and warm streams go up.

Cellars and basements store not only conservation, but also stocks of vegetables and fruits, which tend to "breathe".

When arranging a ventilation system, it is important to remember the following:

1. In order for the air flows to be distributed evenly, it is necessary to make each pipe the same diameter and size. Then the air will enter and leave the room in equal quantities. It is necessary to correctly calculate the dimensions of the pipes in order to provide an optimal microclimate for human health.
2. Do not install two pipes side by side. So it will only be a draft. To ensure the movement of air flow, place the system at different ends of the room. Thus, all the accumulated air will be immediately removed to the outside.
3. In order for the air flows to leave the premises in time, it is necessary to place the pipe as close to the ceiling as possible. It is recommended to equip a special exhaust opening leading to the street. Condensation will not remain in the room, which will help to avoid high humidity.
4. The quality of the hood largely depends on the diameter of the hood.Often, sewer pipes are suitable for cellar ventilation. This is enough to circulate air in a small room.
5. It is recommended to use a grate or hatch to enclose the system.
6. To prevent condensed flows from accumulating inside the pipes, install the most direct structures.
7. The pipe must be homogeneous - without excessively narrow or wide places.
8. To protect the structure from rodents, mount it as high as possible.

The basic principles for arranging cellar ventilation are listed above. For each type of construction, different options are possible, which should be considered depending on the circumstances.

How to make natural ventilation of the cellar

The network is designed and formed at the construction stage of the facility - it's easier than installing air ducts in a finished building. But sometimes the owners make adjustments to the house, and the basement expands, requiring new networks. Here you have to work with the finished box.

A few tips from the pros:

• When installing the system in a cellar, which stands separately, a hole is made in the ceiling. An air duct is brought into the hole, then it is fixed.
• Installation of the network in the cellar under the living quarters has its own peculiarities. The exhaust pipe is built into the passage area of ​​a common house shaft or canal. This channel must go outside.
• The supply air is formed in the upper part of the basement or cellar. If this is a separate building, the pipe is brought out below the level of the exhaust duct.
• The external openings of the ventilation ducts are closed with gratings and fungi. The first - to protect against insects, the second - from rain, snow.

Calculation of the diameter of air ducts and their installation system

Masters advise to adhere to a simple formula - for 1 m2 of the basement you need 26 cm2 of section. It turns out that for every centimeter of pipe diameter there are 13 cm2 of section. The calculation is: (S cellar x 26) / 13. Example: cellar area 8 m2, calculation (8 x 26) / 13 = 16 cm. A pipe is bought with a diameter of 16 cm.

The installation scheme differs in the number of pipes. It is recommended to use two ducts of the same size. This ensures that an optimum level of air circulation is maintained. If you need to speed up the outflow, a larger pipe is mounted on the hood.

Air ducts should be located away from each other and with a minimum number of turns throughout the network. The more bends, turns, the stronger the hydraulic resistance to air flow. Ventilation in this case will work with low efficiency.

Choice of duct material

Thinking over how to make ventilation in the cellar with your own hands, the owner needs to choose the material for the air ducts.

The following products are on sale:

1. Asbestos cement. Pros - resistance to temperature fluctuations, resistance to corrosion, long service life. Such pipes have a length sufficient for the installation of air ducts without welding. Cons - massiveness, fragility.
2. Galvanized metal. Light weight, low cost, ease of installation and resistance to rust are pluses. Minus - any scratch will lead to the appearance of holes.
3. Plastic. Durable and practical products with smooth inner walls guarantee good air permeability. PVC air ducts do not rust, they do not need to be cleaned, they last more than 20 years and are inexpensive. In addition, light weight and the possibility of choosing any length help to carry out installation alone.

Required accessories

The master will need the following set:

• air ducts;
• connecting elements;
• sealant;
• lattice;
• fungi.

Depending on the degree of automation, duct fans, split systems, dehumidifiers, hygrometers and sensors will come in handy. The price of the structure depends on the equipment and reaches several hundred thousand rubles.

Stages of work on the installation of ventilation

After the cellar ventilation scheme is selected, all the details are ready, you can proceed to the formation of the structure:

1. In a separate building, make a hole in the ceiling. Through it, lower the duct pipe. Fix under the ceiling at a distance of 15 cm from the surface. On the street, raise the hood 150 cm above the ground or the roof of the cellar.
2. In the opposite corner, make a second hole in the ceiling or wall. Install the supply air duct, the end of which is lowered to the floor. Placement not lower than 20 cm and not higher than 50 cm from the floor.
3. The supply pipe on the street should not be high, 25 cm is enough. The lower the intake of the supply ventilation is located, the higher the pressure difference at the outlet and inlet. The pressure difference affects the draft and the intensity of air exchange.
4. When a pipe is led through a wall, a deflector or grate is put on its end.

1. Valves are installed on the pipes inside the cellar. The plates help regulate the strength of the air currents. By opening the damper, the user receives a powerful inflow and exhaust, closing it reduces the speed of air transportation.

After assembly, the system is tested. The supply pipe is checked with a sheet of paper - attach, trace. If it sways, there is an inflow, the system is working. The hood is checked with a candle flame or tow smoke - bring it to the pipe, follow the direction of the flame or smoke.

External branches are closed with a lattice, fungi. Sometimes deflectors or recuperators are used. If the owner knows that the installation of fans will be required in the summer, the pipes are selected based on the diameter of the device.

Equipment for the ventilation system

For the arrangement of ventilation ducts, asbestos-cement, plastic or galvanized metal pipes of square, less often round section are used.

Asbestos-cement structures are resistant to corrosion, withstand frost and moisture well, and have a long service life. Such pipes are of sufficient length to allow the installation of an air duct without welding.

Asbestos cement pipes have many advantages, however, care must be taken during their transportation and installation, as they are fragile and can break.

Pipes made of galvanized metal are lightweight and relatively low cost, they are resistant to corrosion and easy to install. Galvanization is suitable for wet areas, where it will serve reliably and for a long time under suitable operating conditions, but if they are violated, the zinc coating may be damaged.

Most often, plastic pipes are used to organize ventilation. The smooth inner surface provides good airflow permeability. Plastic air ducts do not require cleaning and do not rust, their service life is more than twenty years, and their price is noticeably lower than pipes made of other materials.

The main disadvantage of plastic structures is the high flammability of the material, so they cannot be installed in rooms where the temperature can rise to extreme values.

We carry out calculations

Before starting any construction work, it is necessary to make appropriate measurements and draw up a drawing plan. The diameter of the pipes plays a decisive role in ensuring effective ventilation. It should be such that the amount of fresh air is sufficient to ensure an optimal microclimate in the basement.

The diameter of the pipes is determined in a fairly simple way. The number that determines the diametrical section of the pipes should be twice the number that expresses the area of ​​\u200b\u200bthe cellar. For example, if the area is 10 m², then the diameter of the pipes should be 20 cm. This is the simplest way to calculate. You can apply another one: 26 cm² of pipe area is calculated per square meter.

Conclusion

The right choice, installation and operation of the ventilation system is the key to the successful operation of the cellar. Each of them is individual. The principles of operation are the same, but the conditions are different.

Only your own observations and records about the weather, the position of valves, gates, doors, hatches (at least during the first year) will help develop the correct algorithm.
