Installation of forced ventilation in a private house

[zihadhosenjm40]

The essence of the main requirement is that the volume of air to be removed must be equal to the amount of incoming air. If this rule is not followed, various unpleasant odors will penetrate into the room along with the air. If there is a large imbalance between the volume of incoming air and the exhaust, drafts will appear.

Combination of ventilation and recirculation
Recirculation ventilation is called SV when the air removed from the room returns back through the inflow with an admixture of fresh air. The disadvantage is that its use is limited by SNiP, and in regions with a cold climate it does not work very effectively. Its action is limited to one room.

Recirculation allows you to save on electricity consumption chinese overseas europe data power is spent only on heating a small volume of air taken from the street.

The recirculation system scheme can be converted into a regular supply and exhaust ventilation by closing the recirculation valve and fully opening the supply and exhaust. If you do everything the other way around, the system begins to circulate air.

When the supply and exhaust valves are only partially opened, fresh outside air will begin to mix in. By adjusting the degree of opening, the flow of elements that ensure comfortable living is optimized.

Forced air exchange is superior to natural air exchange in many ways:

It works regardless of the weather.
Cleans air more effectively.
It is possible to adjust the rotation speed and power of the fans.
The air flow can be set in motion not only by means of a duct fan, but also by using monoblocks, which are easy to install.
The main disadvantages are dependence on electricity supply and the need for periodic replacement of individual elements. There are several mechanisms for forced ventilation.

This can be a single supply and exhaust unit, a set supply system, an exhaust system, a duct air conditioner. The most effective is considered to be a supply and exhaust SV. The design includes a fan, automation, sensors, filters.
