Version 6.00.05 introduced specific enhancements and critical bug fixes to improve the accuracy of duct system simulations: : CD11-4 : Straight Duct, Round, Constant Equal Friction. CD11-3 : Straight Duct, Round, Velocity Limited.
Always ensure you are using the latest minor patch of version 6.00, as updates resolve underlying mathematical edge cases where specific geometry inputs could result in calculation errors.
update continues this legacy, offering refined data and improved usability for professionals. What’s New in Version 6.00.05?
| Tool | Purpose | |------|------| | | Quick reference for approximating duct sizes and equivalent sizes of sheet metal duct versus flexible duct (compressed at 4%, 15%, and 30%) | | SMACNA HVAC Duct Construction Standards | Provides fabrication and installation requirements that complement the DFDB’s loss coefficients | | ACCA Manual Q | Low‑pressure, low‑velocity duct system design guide that includes quick‑fitting loss tables compiled from ASHRAE and SMACNA handbooks | | DuctSizer | Determines appropriate round, rectangular, or oval duct sizes based on flow and velocity | ashrae duct fitting database version. 6.00.05
Fittings within the database are organized using a standardized alphanumeric coding system. This structure helps users quickly navigate the thousands of options available. Code Breakdown The coding system typically follows a structured taxonomy:
Review the calculated Reynolds number, loss coefficient, and localized pressure drop. Export this data to an Excel spreadsheet or design report for submission to code officials. Conclusion
Instead of manually flipping through hundreds of pages in the ASHRAE Handbook—Fundamentals , Version 6.00.05 allows users to input specific geometry, flow rates, and velocity parameters to instantly retrieve exact pressure loss values. Key Features of Version 6.00.05 Version 6
Seamlessly toggles between I-P (Inch-Pound) and SI (International System) units.
Advanced fluid dynamics software supports importing loss coefficients from the DFDB. Ensure you map the correct reference area and velocity index.
Supports both standard International System (SI) and Inch-Pound (I-P) engineering units. Database Fitting Classifications update continues this legacy, offering refined data and
