How VAV Boxes Work | HVAC Zoning
How VAV Boxes Work? A Variable Air Volume box is typically installed in HVAC systems in commercial buildings and provides heating and cooling for occupants.
There are different types of Variable Air Volume boxes but how a Variable Air Volume box works is fundamentally the same from one Variable Air Volume box type to another.
Essentially a Variable Air Volume system allows an HVAC systems design engineer a way to zone large areas in workspaces such as office buildings and other places where there are large spaces that need heating and cooling or simply just cooling in rare cases.
Furthermore, the concept is simple but making it energy efficient and keeping everyone comfortable has taken some time from the inception of the Variable Air Volume box.
