VAV (Variable Air Volume) system. A VAV system consists of a large air handler and VAV boxes or zones. Usually found in larger commercial buildings the VAV boxes consist of a damper usually controlled by a digital signal now but with pneumatics in the older systems. They are designed to vary the air flow at a constant temperature. Some have hydronic heating and cooling coils, electric booster heaters, or booster fans as well. These systems are usually hooked to a central control system.
