Vav box

What is the basic difference between CAV and VAV box? A variable air volume unit (VAV) is a device commonly used in air conditioning ducts to control air volume while maintaining a constant temperature. The amount of air can be adjusted by adjusting the dampers. A CAV (Constant Air Volume) cabinet is equipment commonly used in AC ducts to maintain a constant airflow.

How do VAV boxes work?

The variable air volume (VAV) box is part of the air conditioning system. It's on the canals. It is designed to control airflow to a specific area called a "zone". VAV adjusts the amount of air for the zone by opening or closing the valve, thus controlling the amount of conditioned air supplied to the zone.
