Variable air volume system or VAV system is most commonly used in modern buildings HVAC system. In the VAV System volume of the supplied is varied to meet the thermal load demands while the temperature of the supplied air is kept constant. While the CAV system is opposite where air volume is constant while the temperature is varied as per the demand. VAV system allows individual temperature control for different zones supplied by the same AHU. VAV system is also energy efficient compared to the CAV system. In a VAV system, a VAV box or VAV terminal unit is installed in each zone/room above the ceiling. This VAV box controls the amount of airflow supplied to the zone based on the zone thermal load. A thermostat or wall module senses the zone temperature and in turn controls the VAV damper. A VAV controller(DDC controller) with a built-in motorized actuator is directly mounted on the damper which controls the damper opening and closing.
There are two types of VAV boxes:
Pressure dependent VAV and Pressure independent VAV. We discussed the difference between pressure-dependent VAV and pressure independent VAV in this video.
