Ashrae Duct Fitting Database Version 60005 -

The 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

Version is the latest release under the ASHRAE Research Project RP-1853 , and it’s not just a cleanup—it’s an expansion.

Users select the fitting from the categorized library (e.g., a 90° elbow).

If you’ve ever spent a late night staring at a complex duct system, wondering if that custom transition really behaves like a “45-degree entry conical tee,” you know the pain. The ASHRAE Duct Fitting Database (DFDB) has long been the secret weapon for engineers who prefer science over swag. But version ? It just raised the bar. ashrae duct fitting database version 60005

Comprehensive Guide to the ASHRAE Duct Fitting Database Version 60005

The ASHRAE Duct Fitting Database is a comprehensive digital catalogue of resistance coefficients (K-values) for HVAC duct fittings. It is designed to help engineers calculate the pressure drop caused by fittings in a duct system quickly and accurately. By using the DFDB, engineers can automate pressure-drop calculations, enhance accuracy, and comply with ASHRAE Handbook guidelines.

Ensuring that air reaches all zones as designed.

While Version 6.00.05 functions as a standalone desktop utility, its underlying data structure is highly integrated into modern Building Information Modeling (BIM) tools.

Extraneous aspect ratios (e.g., a rectangular duct that is 60 inches wide but only 6 inches high) may exceed the validated limits of the ASHRAE research data, causing the software to flag a warning. Try to keep aspect ratios below 4:1 whenever possible. Conclusion Users select the fitting from the categorized library (e
