VAV

A Variable Air Volume (VAV) controller is used in HVAC systems to automatically adjust the amount of supplied air for each zone based on the current demand for heating or cooling. By continuously varying the airflow rate, a VAV unit provides optimal comfort levels and improved energy efficiency compared to constant air volume systems. VAV controllers are often integrated with a Building Management System (BMS) for precise temperature control and are widely used in offices, cleanrooms, and other environments where flexible climate control is required.
