How a Variable Air Volume System Works
www.personal.psu.edusuch a system is a variable air volume, or VAV, system. A VAV system is a type of air distribution system that supplies one specific temperature of air to each space in a building but controls the temperatures within the building by changing the amount of air supplied to each space. Since the VAV system can

www.ehs.ucsb.eduIII. Variable Air Volume Systems A. Properly designed Variable Air Volume (VAV) systems are allowed, e.g. the “Phoenix” system. Use of motion sensors at the hood to setback the face velocity to a minimum of 60 ft/min during periods of non-use are permitted. The primary incentive for using VAV is energy savings. However, designers must

pdhonline.comVAV Systems – Benefits Here are a few of the advantages of VAV systems: 1. Efficiency – VAV systems are low on energy consumption. During lean periods, the air handling unit fan can run at a slower speed (through the use of a variable speed drive) and the amount heating and cooling mediums running through the coil can be reduced (through
