Ventilation basement and cellar of a private house - multiple devices circuits and their features

Ventilation basement and a detached house cellar

Effective use of basements and cellarsimpossible without the normalization of temperature and humidity parameters of air, because the lack of air circulation promotes moisture, which leads to the defeat of the ceiling and walls of a fungus and an extremely negative effect on the preservation of the stock of vegetables and home conservation, with which full normal cellars and basements. properly arranged garage ventilation with a cellar will help prevent prematurecorrosion of the car body. High-quality ventilation of the basement of a private house will provide an opportunity to make little use area before it is suitable for further arrangement of a studio, gym or storage. Consider now more information on how to make the ventilation in the cellar, in the basement or garage of a private house. The general understanding of the process will be an impetus to the practical application of the information received, which ultimately will allow efficient use of the usable area.

Features ventilation unit in the cellar

As mentioned above, effective ventilationcellar in the garage - one of the necessary conditions for the safety of the car, but here we consider only the technical aspect of the destruction of the iron for longer stays in a highly humid environment. Much more important is the fact that high concentrations of vapor in air fuels and lubricants, fuel combustion products (exhaust gas) can be dangerous to health. Therefore it is necessary of all possible options to select the most effective device of ventilation in the basement, bearing in mind, of course, economic feasibility.

Characteristics of the natural unit in the basement

Thus, the ventilation unit in the basement mechanicalmethod can be costly. The use of natural ventilation options arrangement based on the principle of natural recirculation of air is preferable in technical areas. To implement such a ventilation system is necessary to extract the device and supply air ducts. The inlet exhaust duct should be the ceiling, and the supply - in the opposite corner of the room, as close as possible to the wall at a height of 0.5m from the floor.

Driving basement ventilation device in the garage

In order to ensure optimum traction location of the outlet of the supply duct should be significantly lower exhaust

This arrangement will ensure optimum circulationair. As the supply air flow of fresh air enters the store and removes waste. Removal of contaminated air occurs naturally through the exhaust duct. The speed of the air flow through the channels depends on the height of the exhaust duct and the difference in temperature inside and outside the cellar. The height of the ventilation exhaust pipe should be above the roof ridge or roof, only exhaust air output will be effective. For obvious reasons, it is sure to supply air outlet protective shield or baffle. If it is technically possible to build a duct near the chimney of the boiler or fireplace, be sure to use it - such an arrangement will increase traction in the exhaust duct (due to additional heating). It is desirable to supply both special duct dampers to prevent possible freezing of storage in extreme cold.

How to make the ventilation in the basement

Part of the air passing through the attic space must be warm.

Option to supply and exhaust air duct

For small-volume storage can beuse some simplified, so to speak, design. Supply and exhaust duct and is designed to supply fresh air and to remove the waste by means of a single wooden structure containing both supply and exhaust duct. Simplified cellar ventilation system in this case enables you to capture a very small volume of air for ventilation.

Ventilation device with dual duct

The scheme demonstrates how the device ventilation duct with a two-channel valve to adjust the traction

It is also possible the ventilation unit in the cellar with no fresh air. Air flow in this case will be carried out through various cracks, leaks.

Air holes for ventilation of the basement of a private house

If a basement is slightly above ground level, the air supply through a specially arranged air holes (necessarily equipped with grids against rodents) will be the best option.

Forced method

The main disadvantage of natural ventilationis dependent on weather conditions, such as ventilation is most effective in the winter because of the large temperature difference, one might say, even too efficient, so in the winter it is necessary to close the air holes used for air supply in order to avoid freezing of the basement. In the summer, because of the small temperature difference between natural ventilation may not be sufficient to arrange an optimal ventilation. Proper ventilation of the cellar should provide temporary difficulties ventilation. Perhaps the improvement of ventilation scheme shown above by an additional exhaust duct fan equipment. Equipped with supply channel blower for continuous operation is not desirable, because the intense pumping fresh air in case of insufficient exhaust duct efficiency will contribute to polluted air blowing through various leaks and cracks.

Proper ventilation of the basement, which is used for arranging the gym, billiard room

Forced aeration and ventilation is required in the basement, which is used for arrangement of recreation areas

Combined ventilation system is used forthe need for rapid drying of the basement. Installation of an electric fan in the lumen of the opening of the supply duct ventilation will speed up the necessary performance at a time when natural ventilation is ineffective. Intensive air injection at the inlet hatch open and, of course, open throttle exhaust duct ensure rapid drying of the premises with high humidity in the serene hot days. Installation of fans in the supply and exhaust air duct makes sense for ventilation devices in areas with a large area. The operation of such ventilation systems require significant energy costs. As you can see, the ventilation in the basement with his own hands can be arranged only quite effectively with the understanding of the processes and the careful study of the issue.

Using the automated system

cellar ventilation should be carried outwhile maintaining the stability of temperature and humidity, it is technically possible only in the case of the climate of high quality equipment. Thoughts on how to make the ventilation in the basement of the "little blood", can be realized in an irresponsible decision to bypass the need to develop technical requirements for the preparation of the premises. Subtleties miscalculations loads on the power output point, the ratio of service areas with the necessary equipment capacity and other subtleties of preparatory work seem insignificant. Meanwhile, the necessary climate stability can be achieved only qualified installation. Ventilation in the cellar with their hands can be done, but only with appropriate training and a thorough study of the issue. If necessary, the installation of a split system (for maintaining the stability of the climate parameters) is better to take the help of highly qualified specialists.
