The ASHRAE Duct Fitting Database Version 6.00.05 is a valuable resource for engineers and designers working on HVAC projects. With its expanded database, improved data accuracy, and enhanced user interface, the database provides a comprehensive and efficient tool for designing and analyzing duct systems. By using this database, engineers can ensure that their designs are accurate, efficient, and compliant with industry standards, resulting in better system performance and reduced energy consumption.

New entries for straight round ducts (constant equal friction and velocity limited) and flexible elbows with specific radius ratios (r/D=1.0 and 1.5). Enhanced Input Ranges:
This version introduced several critical additions and technical fixes to improve the accuracy of air distribution modeling: : CD11-4 : Straight Duct, Round, Constant Equal Friction. CD11-3 : Straight Duct, Round, Velocity Limited. CD3-22 & CD3-23 : Flexible elbows with ratios of 1.0 and 1.5, respectively. ΔP=Co×Pvcap delta cap P equals cap C sub
High pressure drops usually equate to high turbulence, which creates localized noise. By utilizing accurate empirical data, engineers can predict high-resistance zones and add appropriate attenuation before construction begins. Software Stability
ASHRAE Technical Committee 5.2 (Duct Design) has announced that is in early development. Planned features include:
