The impending publication of the ASHRAE Duct Systems Design Guide will enable engineers to design duct systems that minimize the installed cost of the ductwork, minimize system-generated noise, and minimize fan energy. The guide will describe the equal friction and static regain duct design methods. The equal friction method calculates the duct size based on the initial friction loss rate. For the static regain design approach, main ducts and branches are then sized to achieve a balanced pressure loss from section to section. Both duct design approaches use the ASHRAE Duct Fitting Database (DFDB) to calculate fitting loss coefficients.
