Air Ventilation System
Air ventilation system is the intentional introduction of ambient air into a space and is mainly used to control indoor air quality by diluting and displacing indoor pollutants; it can also be used for purposes of thermal comfort or humidification.
Air ventilation system is providing to control the air contamination rate of an area to a desired limit and gain maximum productivity. In buildings air handling systems are usually known as ACMV (Air Conditioning and Mechanical Ventilation). Certain regions around the world regulation of temperature can be achieved using only ventilation. In these regions conditioning of air is done regulating humidity using economizers and humidifiers. Because of these energy management in ventilation units are more focused.
Air ventilation systems are preferred in cold climates where they are less likely to draw moist air into the building. Oppositely, supply ventilation systems control moisture better in warm climates. Balanced ventilation systems work in both cold and warm climates, but they’re more expensive to install. Heat-recovery systems exchange indoor air with outdoor air.
The most common method of allowing fresh outdoor air to replace indoor air in a home. Today, it’s usually not the best ventilation strategy, especially for homes that are properly air sealed for energy efficiency. Natural Air ventilation system also usually doesn’t provide adequate moisture control.
