A VAV system, also known as Variable Air Volume, is a type of HVAC (Heating, Ventilation, and Air Conditioning) system. The main purpose of a VAV system is to serve as a control mechanism to adjust the air volume in an area based on the current occupancy and temperature. In other words, a VAV system provides air conditioning and temperature control in an area by varying the volume of air depending on the temperature and people present. To do this, a VAV system typically contains a controller, damper, and a fan.
The controller is used to ascertain the temperature of the room and the number of people present, and then adjust the damper and fan accordingly. The damper is a mechanical device that is used to regulate the airflow and the fan is used to blow the air. The fan and damper work together to reduce or increase the amount of air entering the room, by controlling the temperature and airflow, which ultimately affects
