How a Variable Air Volume VAV System Works

This video explains how a Variable Air Volume System works including the VAV box or Terminal Unit. Zoning is also explained. How do Engineers determine how many VAV boxes are required? How are VAV boxes controlled? We'll cover the two most common methods of controlling VAV boxes and the Air Handler.
