Installation of a mechanical ventilation system

[zihadhosenjm40]

One difference is the installation of an axial or centrifugal fan in the exhaust duct cavity.

The supply air will not enter the garage basement with an inspection pit from the general ventilation system - the level is too low. It is necessary to bring a separate supply and exhaust to this room (+)

The power of the ventilation unit should not exceed 100 W, this is enough. The fan must be built into an insulated segment of the air duct, otherwise condensate will enter it.

To control the operation of such a fan, an electronic timer built into the adapter between the electrical outlet and the power plug of the exhaust device will be useful.

Keeping the exhaust fan on for a long time is not hong kong mobile database due to its energy consumption, and there is no need for it. In addition, in winter, combined garage ventilation will be too effective and will cool the garage too much.

An adapter with a timer will allow you to set the frequency and duration of the fan operation for 24 hours and several days in advance.

By placing an electronic timer between the socket and the power plug of the hood fan, you can control the on/off cycles of the electromechanical element of the hood system.

Note that when choosing a sufficiently powerful centrifugal ventilation unit, a larger cross-section for the exhaust duct may be required. We remind you that the choice of the cross-section of the air-conducting pipe depends on the air flow rate.

If the internal diameter is insufficient, the hood will make loud noise and draw air poorly.

Its main advantage is its independence from natural factors. There are two main disadvantages: dependence on electricity; fairly high cost. Air inflow and removal of exhaust air volume are performed by centrifugal fans.

The following mechanical ventilation systems are installed in car boxes:
