WebThe objective of good duct design is to: Optimize duct size (manufacturing costs); Minimize duct system friction losses (operational cost); Reduce duct system acoustics (environmental costs); and. Minimize air balance procedures (commissioning costs). This 6 PDH online course is intended for mechanical and HVAC engineers, architects, building ... WebBrooks identifies duct design methods such as constant velocity, velocity reduction or equal friction methods. These are sizing methods where the diameter of the ductwork can be determined without calculating pressure drops. After the entire system is sized, it is analysed to determine the pressure drops and a critical path.

For this reason, duct design methods should be reconsidered for VAV systems. Three duct design methods are presented in the 1997 ASHRAE Handbook—Fundamentals (ASHRAE 1997): equal friction, static regain, and the T-method. Of the three, the T-method, introduced by Tsal et al. (1988a, 1998b), is the …
