HVAC – Variable Air Volume Systems

Course Description:

A variable air volume (VAV) system basically supplies air at a constant temperature and varies the air quantity delivered to each zone to match the change in room load. In a VAV system, an air handling unit (AHU) cools or heats air to accommodate the zone with the most extreme requirements, supplying the air through ducts to various zones. At the individual zone or space, the amount of air to be provided is regulated by dampers within a VAV box or terminal. In this course we will discuss the advantages, dis-advantages, and uses of VAV systems.

Learning Objectives:
