HVAC Design Overview of Variable Air Volume Systems

A. Bhatia, B.E.

Variable air volume (VAV) is a technique for controlling the capacity of a heating, ventilating, and/or air-conditioning (HVAC) system by varying the amount of air. The advantages of using a VAV system are twofold. The first advantage is that space temperatures can be controlled within acceptable limits over widely varying internal and external heat gains caused by factors like weather conditions or exposure to the sun. The second advantage is reduced energy consumption. The former benefit contributes to occupant comfort and productivity, whereas the latter is attractive to owners and building operators.

Variable Air Volume (VAV) systems are now widely used for commercial buildings, and you need to understand all the different types. This 4 - hour course outlines the basic fundamentals for the design of Variable Air Volume system.

The course includes multiple-choice quiz at the end, which is designed to enhance the understanding of the course materials.
