VAV HVAC (Variable Air Volume) is a type of heating, ventilation, and air conditioning system that seeks to provide the desired temperature and humidity levels in the most efficient manner possible. This type of system utilizes the principles of variable volume which requires the control of the air flow rate. VAV HVACHVAC systems move air through the space at a constant temperature, but regulate its volume as needed, thereby optimizing energy efficiency and cost effectiveness. The variable air volume system also offers improved comfort levels by allowing more precise temperature and humidity control over the entire area.
