Ventilation Air

Definition

Ventilation air is defined as the total air in a system, which is a combination of air brought into the system from the outdoors and the air being recirculated within the building. Sometimes, it is used to refer only to the air brought in from the outdoors.

Purpose

Ventilation air is critical for maintaining indoor air quality by providing fresh air, diluting indoor pollutants, and regulating temperature and humidity. It helps create a comfortable and healthy indoor environment.

Examples of Use

• HVAC Systems: Incorporating ventilation air in HVAC systems to ensure a constant supply of fresh air and maintain indoor air quality.
• Commercial Buildings: Using ventilation air to improve air quality in offices, shopping centers, and other public spaces.
• Residential Homes: Implementing ventilation systems in homes to provide fresh air and control indoor humidity levels.

Related Terms

• Indoor Air Quality (IAQ): The quality of air within and around buildings, as it relates to the health and comfort of building occupants.
• Air Exchange Rate: The rate at which outdoor air replaces indoor air within a building.
• Recirculated Air: Air that has been circulated within the building and is reused, often mixed with fresh air.

Notes

Proper ventilation is essential for reducing indoor air pollutants and ensuring a healthy living and working environment. Ventilation systems should be designed and maintained to meet the specific needs of the building and its occupants.
