This module will look at the way commercial duct design creates an airflow conduit for interconnecting an air handler, VAV, and CV terminals, and room air distribution devices as a means of delivering
conditioned air to the occupants of a building. A step-by-step design process will be presented covering such aspects of duct design as zoning, load determination, layout, sizing, and determining static
pressure losses for system fan selection. After completing the module, participants will be able to manually size ductwork using either a friction chart or a duct calculator.
