Without a ventilation system, no basement room can be limited, since if there is a lack of a constant flow of cool air, dampness cannot be excluded work out. In basements and cellars, as a rule, not only canned food is stored, but also fresh vegetables and fruits that "breathe", from which humidity will certainly accumulate in the room. In addition to this problem, the walls can absorb moisture from the earth from the outer edge if the waterproofing of the base of the house and the basement was poorly organized during construction.
How to make ventilation in the cellar with your own hands?
At the heart of the ventilation are the laws of physics, and if we carefully analyze its basic scheme, in this case we can see that it is organized very easily and simply.
2 ventilation holes are taken into account in the cellar room, through one of which fresh air enters the cellar, and through the second it is removed simultaneously with all vapors. However, the scheme would be of little efficiency if pipes of the established diameter were not brought to the ventilation openings.
Also, the quality of ventilation is very dependent on the exact location of the exhaust and supply pipes and on their elevation above the soil surface above the cellar.
Ventilation pipes have every chance of being introduced into the walls of the basement if it is located in front of the dwelling or the car garage, or brought out through the ceiling, in this case, if the basement is organized in the yard, as a separate building.
Another significant factor in the calculation and installation is the level of construction of pipes from the basement floor and bringing them out to the street, since a very large amount of cool air can enter the room, which will be unsafe for vegetables stored in chests in fresh. You cannot make few holes, since the dank air will not leave the room entirely, and therefore, the food stored in it will certainly rot.
Initially, you need to proceed with the installation of one of the types of ventilation structures, you need to study and familiarize yourself with the advice of experienced people, which should be taken into account during the design and construction work:
Of course, the best view is to adapt the ventilation scheme even during the construction of the cellar.
In order not to guess in the future where it is preferable to install pipes, ventilation must be immediately entered into the cellar plan.
However, under no circumstances is it possible to install a chimney with a diameter less than that of the inlet, since air under such criteria can begin to remain outside the room. This will negatively affect the foodstuffs stored in the cellar, however, the main threat is always different - the danger of a person's well-being is formed when he descends into a gas-polluted underground room.
They should be installed on opposite walls or in opposite corners.
This is done in order for the new stream, first to go out into the street, to pass through the entire room and stir up stagnant air to the outlet into the chimney.
Such a location is enough to promote stable air purification, without stagnation in the ceiling area, which means it will preserve food.
In this case, 2 doors are made, one is insulated - for winter, and the second - in the version of the frame, with a small mesh attached to it. The fence is needed so that small rodents do not make their way into the cellar.
The insulated opening is removed in the summer in order to continuously ventilate the cellar . If the room above the basement is insulated, in this case, it is allowed to carry out airing sessions in the winter.
They can help measure the arrival of cool air in extreme cold and, therefore, decrease in warm air, to strengthen the required local climate in the cellar.
If the chimney heads are placed exactly in a vertical position, they should be protected from precipitation, dust and debris from getting inside by defining from above metal umbrella or ventilation deflector.
The ventilation deflector is an ideal type, since it bases an artificial vacuum and increases gravity.
When using a deflector, a sphere of vacuum is formed around it, and this manifestation contributes to an increase in thrust.
There are 2 basic types of fan structures - these are natural and forced. And this or another type is chosen in connection with the size and layout of the basement room.
Natural ventilation is based on the difference in pressure and temperature in the room and outside. Effective work largely depends on the correct placement of the pipes. So, the inlet opening must be at the top of a maximum of 250: 300 millimeters from the floor, and the exhaust outlet must be 100: 200 millimeters below the ceiling.
Positioning it below is unacceptable for now, otherwise the ceiling will get wet.
This method of ventilation may be undoubtedly not enough for a large-sized cellar room, or in the event that it consists of many rooms.
In the method of forced ventilation there are always the same channels (pipes), however, fans are installed in them to form forced air movement.
In the lightest forced-type modes, the cooler is brought out to the exhaust duct. In a similar way, artificial filing is formed in the room, which promotes the proactive flow of cool air into the basement through the supply passage.
The performance of the selected propeller will depend on the size of the room.
They also act differently - they put fans on both the supply and exhaust paths. This happens significantly in voluminous, complex basement rooms.Here you will certainly need the support of a professional in order to calculate the coherence of the flow in and out of the atmosphere, that is, the diameter of the channels and the power (performance) of the fans installed in them.
For each type of ventilation, it is imperative to correctly make your choice with pipe diameters.
The calculation methods used by high-class designers are very difficult, and it makes almost no difference to present them in full. However, when installing ventilation in a small private cellar, it is allowed to use a simple counting methodology.
So, with certain assumptions applicable in the information criteria, it is allowed to assume that for the purpose of 1 square meter of the cellar section, 26 square cm of the section of the ventilation channel is needed. So, you can estimate for a sample what pipe diameter will be needed for a cellar with a scale of 3, multiply 2 meters.
Find the area of the room:
S = 3 by 2 and = 6 square meters
According to the confirmed compliance, it will require a pipe of the next size:
T = 6 multiplied by 26 = 156 square centimeters
It remains to find this pipe radius:
R = root (T PI divided) = root (156 divided by 3.
14) will be approximately 7.05 cm
Therefore, the diameter of the supply pipe:
The diameter will be approximately 14 cm = 140 mm.
If only supply ventilation is introduced in the basement, and the hole will play the role of exhaust, in this case it is allowed to slightly increase the profile inlet channel, defining a pipe with a diameter of 150 millimeters.
To ensure air exchange, it is customary to install a pipe with a diameter of 10 on the exhaust duct, we expect 10% more than at the inlet.
Calculate the diameter at the exhaust duct using the formula:
Dw = Dn add 15% = 140 add 21 and approximately it will be 160 millimeters.
Having made the necessary calculations, taking into account all the above-described nuances, it is allowed to proceed to the installation of ventilation.
The approximate location of the supply and exhaust pipes.
The supply pipe is permanently located below.
Possible location of the supply pipe.
The dampers on the pipes can help to precisely coordinate the ventilation.
