Air balancing is the process of adjusting an HVAC system to ensure that the correct amount of air is delivered to each zone or room in a building. Adjustments are primarily made using dampers, which are adjustable plates located inside ductwork. These dampers restrict or open airflow to regulate the amount of air reaching different zones. To correct for over-pressurization, where a zone receives too much air, the dampers in the supply ducts serving that zone are partially closed. This reduces the airflow to the zone,....
