Apartment ventilation: forced-exhaust and forced-supply systems

As a rule, ventilation in apartment buildings does not fulfill its purpose. Therefore, many tenants are thinking about how to make ventilation in the apartment on their own. So that the efforts made are not in vain, it is necessary to determine the air exchange rates, choose the right equipment and correctly install it.

Ventilation calculation

The calculation takes into account the living space and the number of residents. According to the standards for 1 sq. meter requires 3 cubic meters of air per hour. Add to this 30 cubic meters of air per hour for each adult family member.

Knowing the volume of the supplied air, it is easy to choose the right equipment.

The ventilation system of an apartment can be based on natural draft or forced (supply, supply and exhaust or exhaust).

Ventilation type

The natural ventilation of an apartment is that air enters the vents or window slots, and it is drawn into the ventilation ducts (in the kitchen and in the bathroom). However, modern windows are hermetically closed, and tight-fitting doors are often installed between rooms. To restore traction, a special ventilation valve can be built into a window or wall. This is the best way to make ventilation in an apartment simple and inexpensive.

The valve is a very neat device that allows air to flow from the street. At the same time, he does not disfigure the room, does not cool it down.Installation of ventilation in an apartment according to this scheme takes a quarter of an hour.

You can also mount a similar valve in the wall near the radiator. But you have to make a hole in the street with a diameter of up to 10 cm. The device is very simple, it works flawlessly. However, only if the channel for general ventilation of the house is effectively “pulling”.

Installation of ventilation in the apartment

If the ventilation duct is clogged or destroyed, you will have to equip the combined ventilation system of the apartment. There are two options:

• forced-draft,
• forced supply.

In the first case, an exhaust fan is installed in the ventilation duct or an additional extractor hood is mounted in the kitchen above the hob. Turning on, the fan provides a vacuum, which helps to draw in fresh air through the vents or valves. It costs nothing to make such ventilation in an apartment with your own hands - you just need to build in a fan instead of a ventilation grill.

Installing forced-air ventilation in an apartment is somewhat more complicated. It is necessary to provide an artificial air flow from the street. As a rule, it is heated and filtered. This system is quite noisy, so a noise reflector is also needed. Nevertheless, having certain skills, it is quite possible to assemble such ventilation in an apartment with your own hands.
