Ventilation cellar with their hands

No devices of the ventilation system can not do none of the basement, as can not be avoided in the absence of a constant inflow of fresh air dampness.In the cellars and basements are usually stored not only canned stocks, but also fresh vegetables and fruits, which "breathe», from what indoor necessarily picks up moisture.In addition, the walls can absorb moisture from the soil, located on the outside, if during the construction of bad basement waterproofing and basement has been arranged.

at the heart of the ventilation system works are the laws of physics, and if we consider it the concept carefully, you can see that it is arranged very simply and clearly.

General ventilation principle - is extremely easy

General ventilation principle - extremely easy

Indoors cellar provides two vents, through one of which fresh air is supplied to the basement and through the second - displayed along with all the fumes.But system was be insufficiently effective if the vents were not would summed certain pipe diameter.

also the quality of the ventilation operation is highly dependent on the correct positioning of the exhaust and supply air pipe and by raising them above the surface of the ground above the cellar.

ventilation pipes can be installed in the walls of the basement, if he is under the house or garage, or removed through the ceiling, in when cellar is arranged in the yard, as a separate building.

More one thing to consider when per and installation of the system is the height of installation of pipes from the floor of the basement and removing them on the street, because the room could do too much cold air that is hazardous to vegetables stored in bins infresh.You can not make the holes too small, as the stale air will not leave the room completely, and then , stored in it products will necessarily deteriorate.

Recommendations for device ventilation cellar

Before start installation of any of the types of ventilation systems, you need to familiarize yourself with some recommendations that should be considered during the design and construction work:

  • will be correct if the ventilation system starts laid during the construction of the cellar - in this case in the masonry walls are left channels, which are installed in ventilation ducts.
Of course, the best option - the ventilation system the device is still in the construction of the cellar

to subsequently wonder where to install the pipes, ventilation should be immediately included in the cellar project.

  • Adjustable pipe must have the same diameter - this parame tr sd elaet uniform air circulation.If you want to speed up the removal of stale soaked air of dampness, the chimney can take a little larger diameter than the inflow.However, under no circumstances should you install the chimney with a diameter less than that of fresh air, as the air under such conditions may start to stay indoors.This negatively will affect the stored food in the cellar, but the main danger in se same another - created definite threat to human health in its descent in gassy underground room.
  • Never have two ventilation pipes next to each other, as in this case the room is not well ventilated.They need to be mounted on opposite walls or in opposite corners.This is done to ensure that the flow of fresh, before going out on the street, walked across the room and pushed the stale air of reaching the chimney.
  • opening the exhaust pipe must be mounted near the ceiling, as a waste warm air rushes up.Such its location will facilitate the constant clean air without stagnation in the area of ​​the ceiling, and then - and well preserved products.
  • Ventilation hoods pipe ensure good traction rises above the ridge or mound above the ceiling cellar, at least 1500 mm.
  • for ventilation systems are most commonly used plastic pipes, intended for sewerage.For small spaces such diameter is usually sufficient.
  • If a cellar under the garage or under a different utility room, then as an exhaust hole, you can use an access hatch.

In this case, made two two Rtsy one insulated - winter , and the other - in the form of a skeleton, with fixed on it shallow bars . Grille necessary in order to not slipped into the basement small rodents.

warmed hatch removed in summer to keep airing cellar.If the space above the basement insulated, even in the winter time you can spend sessions airing.

  • installing ventilation in the cellar, located under the house or the garage, need to provide the , to the twists and turns and fresh air, and the chimney was as little as possible.Ideally, the better to achieve this arrangement, the pipe was absolutely straight.
  • pipe along its entire length must have a diameter of, without extensions and restrictions.
  • Outdoor supply air pipe, if it is located high above the ground should always be screened ( bars ), to protect the cellar against rodents or other small animals and birds.
Supply pipe , intake grille

  • recommended to install two pipes regulate the inflow and outflow of air dampers, which are particularly needed in the winter.They help metered flow of cold air in extreme cold and, accordingly, outflow of warm , to maintain the necessary microclimate in the cellar.

  • If headroom pipes arranged vertically, they must be protected from ingestion precipitation, dust and debris, setting the top metal umbrella or deflector.
Deflector - profitable , because it creates an artificial vacuum and increases cravings

Deflector - profitable, because it creates an artificial vacuum and increases cravings

When using deflector around created discharge area, and this phenomenon increases traction.

  • Cut the exhaust pipe, located in the street should be well insulated , in order to prevent occurrence of condensation in the cold season.

Types cellar ventilation

There are two basic kinds of ventilation systems - a natural and forced.A chosen one or the other option, depending on the volume and layout of the basement premises.

Natural ventilation

Natural ventilation on the basis of on pressure difference and the temperature indoors and outdoors.Efficient operation depends on the correct location of the pipes.Thus, the supply hole should be at a height maximum of 250 ÷ 300 mm from the floor, and exhaust - below the ceiling level of 100 ÷ 200 mm.To place it still below impermissible, otherwise ceiling starts syret.This

ventilation may be insufficient for large volume on cellar premises, or in case it consists of several rooms.

Forced ventilation system

The system forced ventilation are all the same channels (pipes), but they are integrated fanscreating a forced air flow.

In the simplest systems of forced type fan mounted on the exhaust duct.Thus, the room is created artificial vacuum that promotes active entry of fresh air into the cellar through the supply hole.Power fan selected will depend on the volume premises.

Ducted fan casing

Duct fan in the housing

incoming and differently - set fans and supply, and exhaust duct.This is true in bulk, complex configuration basements.There certainly need expert help to get the consistency of revenue and exit of air, that is, the channel diameters and power (capacity) installed in them fans.

Calculation ducts diameters

Any form of ventilation is very important to determine the diameters of the pipes.Algorithms of calculation used by professional designers, are very complex, and bring them completely makes no sense.However, if the ventilation equipment in a small private cellar can use a simplified procedure counting .

So, with certain assumptions, acceptable these conditions, we can assume that for one square meter cellar area of ​​26 square centimeters required cross-sectional area of ​​the ventilation duct.Thus, it is possible for example to estimate what Dia tr tr Uba will need to cellar the size of 3 × 2 meters.

find the area of ​​the premises:

S = 3 × 2 = 6

According to this relation, for her need to pipe the next channel cross-sectional area:

T = 6 × 26 = 156 cm²

remains to find the radius of the tube:

R = √ (T / π) = √ (156 / 3,14) ≈ 7,05 see

So, Diam tr pr itochnoy pipe:

Dp ≈ 14 cm = 140 mm.

Provided that the basement is only set supply air and exhaust to play the role of the door, you can slightly increase the input section of the channel, setting the pipe with a diameter of 150mm .To ensure

taken to ensure air exhaust duct mounted on a pipe with a diameter of 10 ÷ 15% greater than at the inlet.In this example, it is possible on the exhaust channel set:

Dv = Dp + 15% = 140 + 21 ≈ 160 mm

ventilation assembling

After the necessary calculations , taking into account allabove nuances, you can proceed to the installation of ventilation.

approximate location of supply and exhaust pipes

  • If the ventilation system is installed after the construction of the cellar, the ceiling it is necessary to make a hole for the passage of air.
  • then, through the hole in the cellar falls pipe, which will work on the hood , fix it on the ceiling, no more than 100 ÷ 150 mm below the surface.
  • Outdoor chimney raised to a height of not less than 1500 mm above the ground or above the roof surface.
Ventilation tube is always located below

Inlet pipe is always located below

  • In the opposite corner of the cellar are also doing a hole in the ceiling or wall, and it installed and fixed air-jet pipe, dipped low to the floor.It should not be placed below the floor 200 mm and not more than 500 mm.
  • Outdoor inflow pipe should not be made very high.If it goes through the ceiling, enough to raise her 200 ÷ 250 mm.It should be borne in mind that the lower intake opening is located inflow pipe, the greater the pressure difference between inlet and outlet, the stronger the natural draft and means - and air flow.
  • If the supply pipe is led through the wall, then it worn ventilation grille or plastic deflector.

  • In the case where the installation of ventilation for cellars held in the house, which features a fireplace or stove, it is recommended to raise the chimney near the chimney, as it activates the flow of exhaust air from the basementfor through large temperature differences.
Similarly, adjust the ventilation flaps in the process help the tubes

Just adjust the ventilation flaps in the process help the tubes

  • recommended to install the valve on the pipe in the cellar to adjust the force of air flow.Opening them to the desired lumen intensity in the room is regulated by circulation of air humidity and temperature.It is from the presence of the damper and proper regulation of the microclimate in the cellar will determine whether the stored workpiece proper state for a long time.

After system is assembled, be sure to should its check on on presence of normal traction

  • To check the pressure of the air flow at the inlet to the air supply pipe must be applied a sheet of tissue paper.If she starts clearly sway, then the intensity of the air supply is good.
  • Another way to check the operation of the system is the direction of the smoke, which may come from burning in a metal bucket of paper.Suffice it to a couple of old newspapers that need to ignite, to burn down to half, and then to dip to a state of decay.

Additional steps for maintaining normal microclimate

To keep in the cellar comfort food storage microclimate, should periodically carry following action:

In order to facilitate the reduction of moisture in the basement, it is necessary to carry outits regular airing.So, in the summer open doors or hatches and fully open valve on the holes.The hot summer wind will make your case - dry and ventilate the cellar.The following will describe other, more effective ways of forced drying cellar.

There are times when you need to contrary - increase the humidity in the room storage.
