VAV systems are the most common HVAC system for commercial buildings but duct design practices vary widely around the country. Duct design practices are seldom based on hard analysis of whether they are optimum from a life cycle cost perspective. This seminar compares various VAV box inlet and outlet duct design options including their impact on first costs and pressure drop. The presentation focuses on single duct VAV reheat systems, but most of the principles apply to other VAV system variations, such as dual duct and fan-powered box systems.
