The course provides instruction on such topics as fan laws, duct types and their configurations, air distribution methods, layout and design of low velocity duct systems, design methods, air delivery systems and fire damper installation. Also covered is the sizing of supply and return air ducts, including the proper selection of supply and return registers and grilles, C.F.M calculations, external static pressure and sheet metal fittings.
