What Is a VAV Box and How Does It Work? Hi Boox
The air that is supplied to a Variable Air Volume box in a VAV system comes from a large air handler and central ductwork. Therefore, the air handler must have the ability to supply the Variable Air Volume boxes with a variable amount of air. The dampers in the Variable Air Volume system will modulate to different positions.

Variable air volume ( VAV) is a type of heating, ventilating, and/or air-conditioning ( HVAC) system. Unlike constant air volume (CAV) systems, which supply a constant airflow at a variable temperature, VAV systems vary the airflow at a constant or varying temperature.

A third type of VAV unit, variable air volume with reheat, is similar to a fan-less VAV box but includes an electric coil. When the air in the damper reaches a specified temperature, the coil reheats the air. In this way, variable air volume units can provide zone-specific heating without adding additional heat to the entire building.

Once simple, variable-air-volume- (VAV-) box selection has become an iterative process complicated by energy- and ventilation-code requirements. What's more, most of the articles regarding the application of VAV boxes are highly technical, leaving us simple HVAC engineers somewhat befuddled, still looking for an easy, reliable, and expedient.
How a Variable Air Volume VAV System Works YouTube
Variable air volume (VAV) systems enable energy-efficient HVAC system distribution by optimizing the amount and temperature of distributed air. Appropriate operations and maintenance (O&M) of VAV systems is necessary to optimize system performance and achieve high efficiency.
