What is ventilation and why it is needed?
Ventilation is an adjustable air exchange process used to maintain purity, air movement, compliance with a certain temperature and humidity.
At a certain stage of construction, a standard ventilation system is designed, in which the air enters through air openings and is also removed due to the difference in the pressure of internal and external air. This action is facilitated by the work of wind, opening the windows, doors, etc. With an organized natural ventilation system, the air circulates due to the special adjustable supply and exhaust openings. The process of natural ventilation directly depends on the action of various external factors, which is the result of which is its inefficiency and the need to install a forced ventilation system.
Forced ventilation distinguish between exhaust, supply and supply-exhaust. The supply grilles contribute to the active flow of fresh air from the street, and the exhaust of it divert. Installation of the grilles is carried out in the area of windows, walls, doors, etc.D. Metal lattices are of special strength and durability.
