The ASHRAE Duct Fitting Database (DFDB) version 6.00.05 is a comprehensive software tool used by HVAC engineers to calculate pressure losses for more than 200 different round, rectangular, and flat oval duct fittings. By entering specific flow rates and fitting dimensions, users can obtain accurate loss coefficient data and associated pressure drops based on authoritative ASHRAE standards. Key Features of Version 6.00.05
System Requirements:
. Version 6.00.05 ensures engineers are using the most current, laboratory-tested data to size fans properly, minimize system noise, and reduce energy consumption. ashrae duct fitting database version 60005
The ASHRAE Duct Fitting Database (DFDB) Version 6.00.05 is a critical software tool for HVAC engineers. It allows for the precise calculation of dynamic pressure losses across more than 200 fitting types.
: The latest version is available via an annual subscription, allowing for easier updates and accessibility. Extensive Library The ASHRAE Duct Fitting Database (DFDB) version 6
Real-Time Calculations: The interface allows users to enter flow rates and fitting dimensions to instantly obtain velocity, velocity pressure, and pressure loss.
Pro Tip: After installation, don't forget to reset your default “Roughness” parameters. Version 60005 resets to standard galvanized steel (0.0003 ft), but your local jurisdiction may require different defaults. Version 6
Reduce liability. Using the correct, up-to-date loss coefficients isn't just about efficiency; it's about contractual accuracy. If you are specifying fan static pressure, using an outdated database (pre-60005) might under-spec your fan by 5-10%.
Disclaimer: ASHRAE periodically updates the database. Always refer to the official ASHRAE website for the most current version number and errata.
