Variable Air Volume Units (VAV’s) 101

This VAV box blog post is the second in a series of posts that will explore how Veris Industries products can be used to monitor and regulate heating, ventilation, and air conditioning (HVAC) applications.

In general, a variable air volume (VAV) box regulates the flow of air to a specific room or zone in a building. It controls the flow of air through the use of dampers. Some VAV box designs include supplementary heating and / or cooling coils to act as mini air handlers. Thermostats control VAV boxes. Specifically, thermostats control zone temperatures by telling the VAV box when and how to adjust its dampers.


Though VAV boxes are widely used in commercial and industrial applications, with the advent of new energy efficiency standards for homes, they are now being installed in some residential applications.
