Building ventilation device.

Adjustable air exchange in the room is called ventilation. This is a whole set of events that serves to create favorable air conditions. He must meet the requirements of the technological process and be comfortable for humans. Each of us, with our activities, emits water vapors, heat and carbon dioxide into the environment. Various production processes occur with the release of heat, gas and dust. From the influence of these factors, the environment in the room will no longer meet hygienic requirements. For this reason, a person’s well -being worsens and his performance worsens. Also, adverse factors affect the safety of equipment, building structures, materials and products. Here you just can not do without ventilation, which of course must meet all standards, but they are reduced to maintaining certain humidity, temperature, mobility and purity of air. Meteorological conditions themselves in the building are laid even when designing internal engineering systems. Each technological process corresponds to a certain maximum permissible concentration of gases, vapors and dust.
