Apartment ventilation: forced-exhaust and forced-air systems
Ventilation in apartments of apartment buildings, as a rule, does not fulfill its purpose. Therefore, many residents are thinking about how to make ventilation in the apartment on their own. So that the applied efforts are not wasted, it is necessary to determine the norms of air exchange, choose the right equipment and correctly install it.
Ventilation calculation
The calculation takes into account housing and the number of residents. According to the standards for 1 square. a meter needs 3 cubic meters of air per hour. We add to this 30 cubic meters of air per hour for each adult member of the family.
Knowing the volume of supply air, it is easy to choose the right equipment.
The ventilation system of the apartment can be based on natural draft or forced (supply, supply and exhaust or exhaust).
Type of ventilation
Natural ventilation of the apartment lies in the fact that air enters the window leaves or window slits, and it is drawn into the ventilation ducts (in the kitchen and in the bathroom). However, modern windows close tightly; tightly fitting doors are often installed between rooms. To restore traction, a special ventilation valve can be integrated into a window or wall. This is the best way to make ventilation in the apartment simple and inexpensive.
The valve is a very neat device that provides airflow from the street. At the same time, he does not mutilate the room, does not cools it. Installing ventilation in an apartment according to this scheme takes a quarter of an hour.
You can 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 it effectively pulls the channel for general ventilation at home.
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-exhaust
- forced-supply.
In the first case, the exhaust fan is installed in the ventilation duct or in the kitchen an additional hood is mounted above the hob. When turned on, the fan provides air discharge, which helps draw fresh air through the windows or valves. Doing such ventilation in the apartment with your own hands does not cost anything - you just need to build in a fan instead of a ventilation grill.
Installation of forced ventilation in the apartment is somewhat more complicated. It is necessary to provide artificial air flow from the street. As a rule, it is heated and filtered. Such a system is quite noisy, so a noise reflector is also needed. Nevertheless, having certain skills, it is quite possible to assemble such ventilation in the apartment with your own hands.
