Variable Air Volume. An air handling system, unlike a single zone, terminal reheat, multi-zone, or dual duct, supplies air at a constant temperature and varies the air quantity supplied to each zone.
Variable Air Volume. HVAC system that controls the dry-bulb temperature within a space by varying the volumetric flow of heated or cooled supply air to the space.

Variable Air Volume. An HVAC system strategy through which the volume of air delivered to conditioned spaces is varied as a function of ventilating needs, energy needs, or both.
Variable air volume. An HVAC design that heats or cools a conditioned space by increasing or decreasing the amount of air entering a conditioned space.
Variable Air Volume. Variable Air Volume or VAV systems control the air volume. The simplest control is a simple On-Off control of fans but the complex damper controls are more common as variable speed control of fans is the most economic method to control the air volume.
