Ventilation of cellars. Briefly about the main

Ventilation of cellars is a very important and usefulengineering system. If the air flow is insufficient, then in the cellars there will be increased humidity, which is fraught with the appearance of fungus, mold and other unpleasant consequences. And this is exactly not necessary to anyone.

The ventilation of the cellar in the house can bedesigned and executed by hand. In this process, there are no specific features that would be difficult to understand. But it is better to have minimal knowledge. And the most important question in this case is the choice of the type of ventilation. Natural or forced. The basic principles of their arrangement are similar, but there are also nuances.

Natural ventilation of basements

The work of this technology is based on the differencetemperatures inside and outside the room, i.e. works similarly to the chimney system in ovens. For its arrangement it is only necessary to lay two pipes:

• Supply. This pipe is stacked so that its onethe end was located at a height of 0.5 meters above the level of the basement floor, and the other would pass through the ceiling and leave the building wall at a height of 1 meter.
• Exhaust. This pipe is equipped in the oppositecorner of the basement. Its lower part should be located at a height of 1.5 meters above the basement floor, and the other end should be located 0.5 m above the building skate.

In principle, nothing complicated in an independentThere is no such ventilation. The greater the difference in temperature, the higher the air flow will pass. But there is one important condition for good ventilation. This is the diameter of the pipes. If it is too small, the airflow can not take out all the moisture. To determine the required diameter, you need to calculate the floor area. Usually the diameter of the pipe is chosen on the basis that a pipe of 26 square centimeters is required for 1 square meter of floor. For example, for a basement with a floor area of ​​8 square meters, a pipe with a diameter of 16 centimeters is required.

The natural ventilation of the cellars can be improved. To do this, create additional traction. Make it simple. It is only necessary to lay a vent pipe next to the chimney.

Condensation may form on the pipes.To prevent this from happening, they should be insulated. For such purposes, any heater is suitable. Roll insulation materials are most often used. They wrap the pipe around us and put on the protective layer.

And the last. Valves should be installed on the pipes. This is necessary in order to control the air flow, as well as to be able to cover the entire system for the winter period.

Forced ventilation of basements

If natural craving can not cope withtasks assigned, then to achieve the goals you can use the fans. Usually one is set for blowing, the other for blowing. In this case, the diameter of the pipeline should not correspond to the proportion that is necessary for natural ventilation. Fans will be responsible for the quality blowing. But this method has a significant disadvantage - such a system is volatile, that is, fans need electricity.
