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. --------------------------------LINKS--------------------------------------------------- CAV System video:    • Constant Air Volume CAV System Explai...   Dampers Video:    • Dampers and Actuators | Building Mana...   --------------------------------------------------------------------------------------------- BMS BMS System Building Automation System Building Management System(BMS) Building Management System Course Building Management System Training BMS Training Building Management System HVAC HVAC Training HVAC Classes HVAC Basics HVAC Course VAV system vs CAV System VAV box VAV System VAV Systems Variable air volume systems Variable air volume system vav system in HVAC VAV system working principle Variable air volume system working principle pressure dependent vs pressure independent vav pressure dependent vs pressure independent vav boxes how vav works BMS system Building Management System BMS Training HVAC basics HVAC training Building Controls Please subscribe to our YouTube channel for BMS training videos.
