What is Ventilation Air?

Ventilation air is the air that is used to provide fresh air into a building or other enclosed space. The purpose of ventilation air is to provide a safe and comfortable environment for occupants, as well as to reduce the risk of health problems associated with poor indoor air quality. Ventilation air can be supplied through natural ventilation, mechanical ventilation, or a combination of both.

Natural ventilation is the process of using natural forces such as wind and convection to move air through a building or other enclosed space. This type of ventilation is often used in residential buildings, as it is cost effective and does not require any mechanical components. Natural ventilation is only effective when the outside air is cleaner than the air inside the building.

Mechanical ventilation is the process of using fans and other mechanical devices to move air through a building or other enclosed space. This type of ventilation is often used in commercial and industrial buildings, as it is more effective than natural ventilation and can be controlled to provide the desired air quality. Mechanical ventilation systems can be either forced or exhaust systems, depending on the type of building and the desired air quality.

Ventilation air is important for maintaining a healthy indoor environment. It helps to reduce the risk of health problems associated with poor indoor air quality, such as allergies, asthma, and other respiratory illnesses. It also helps to reduce the risk of mold and mildew growth, which can be a health hazard. In addition, ventilation air can help to reduce the levels of indoor pollutants, such as dust, smoke, and other airborne contaminants.
