Make a cellar ventilation in the garage with his hands

Desire owners of individual garages equip the cellar is quite natural and justified, asit is possible at the lowest cost to get enough capacious storage for vegetables and canned foods.However, errors in design and construction of a garage with a cellar can lead to very unfortunate consequences: will be hopelessly corrupted stored products, and most importantly - due to the high humidity severely hurt the car.Therefore, the regeneration of the cellar perhaps the most attention should be paid to the effectiveness of the ventilation system for it.

Species ventilation

Total known two types of ventilation to the cellar in the garage:

  1. Natural ventilation.In this case, the removal of moisture from the cellar volume is due to thermal convection.That is, the warm air from the top of the cellar spontaneously rises up and released when the volume is filled with a dry air from the street.
  2. Forced ventilation, where air exchange between the street and the cellar is done with a mechanical supercharger, ie,fans.This scheme is far more efficient, but it requires several large financial investment and the availability of power supply lines.

Construction of natural ventilation.

This scheme is based on the use of two tubes: fresh air, through which climbs from the street and a fresh dry air and exhaust through which moist air is discharged to the outside cellar.

optimum location for the pipe is considered to be the opposite corners of the cellar.With this configuration, a much lower probability of formation of stagnant zones and, consequently, more humid air.

Chimney can be installed in two ways:

  • -through, ie,the pipe passes through the floor of the garage, and then outputted through the ceiling and roof;
  • through the wall of the cellar, where the lower part of the chimney (Fig. 2 designated number) placed horizontally and then rises already outside the garage dimensions.

Driving cellar ventilation

It should choose the length of the chimney so that after installation the upper section turned out to be about 0.5-1 meters above the highest precision of the garage roof.The total length of the exhaust pipe must be at least 2.5-3 m, it is necessary to obtain a sufficient temperature difference, due to which and there is a natural airflow.On the upper part of the pipe, it is desirable to install a deflector, which will strengthen the intensity of the ventilation through the creation of additional dilution and reliably will protect the cellar against the penetration of rain and dust.

deflector for cellar

most effective deflector is one that has an outer diameter twice the diameter of the pipe.The lower section of the baffle housing must be positioned a few centimeters below the vent pipe cutting.If desired, a simple deflector in the form of a tin or plastic cone can be made independently.The lower section of the chimney is located as high as possible under the cellar ceiling.

Inlet pipe is installed so that its lower edge to the floor level was about half a meter.Approximately the same distance should be between its upper cut and ground.In addition, the upper section be sure to provide protective grille that prevents penetration into the cellar cats, mice, rats and other uninvited guests.Instead of grating can use a metal mesh with medium or fine mesh.

as prityazhnoy and exhaust pipes can be used almost any pipe available on the market.Their diameter must be chosen so that for every square meter of the area of ​​the cellar had about 15 mm diameter tube.So often use ordinary plastic or asbestos pipes with diameter 110-200 mm.In practice, the plastic appears preferable because when only slightly lower mechanical strength, it has a much lower weight, easier to cut and easier sealed.Sometimes used sheet metal ducts, but all of its low cost, they are not the most rational choice, becausevery easy to be damaged and fail.

How exhausting and prityazhnye pipes should be fitted with shutters.Special requirements for construction valves is not shown, but in any case they must be able to completely block the flow of air and the removal of the volume of the cellar.Overlapping flap is necessary in case of heavy frost.

Forced ventilation cellar

between the structure of natural and forced ventilation of the cellar in the garage there are no fundamental differences.The only feature of the latter - is the presence of an electric fan for drawing.

electrical safety precautions should be considered when creating a forced ventilation.In any cellar due to the temperature difference between the walls and the air will inevitably be formed condensate, for the removal of which just creates a ventilation system.And this condensation can cause rapid failure of the wiring and fan.Therefore, in order to avoid the risk of electric shock, all electrical equipment must be reliable waterproofing and technical ability to work in conditions of high humidity.

Overall, spending a little time and effort on the improvement of effective ventilation, you can get a convenient storage space for preservation and vegetables, in which the optimum temperature is maintained year-round.
