Ashrae Duct Fitting Database Version. 6.00.05 Work 〈HIGH-QUALITY〉

ASHRAE Duct Fitting Database Version 6.00.05: The Ultimate Guide to Precision HVAC Design

• For systems previously near selection thresholds (e.g., next larger fan or duct size), see if revised losses allow downsizing safely while meeting velocity and noise limits.

Engineers and HVAC designers, the latest maintenance update for the ASHRAE Duct Fitting Database (DFDB) ashrae duct fitting database version. 6.00.05

System Requirements:

• Operating System: Windows 10/11 (64-bit recommended) or any OS that can run Microsoft Access Runtime 2019 or later.
• Memory: 4 GB RAM minimum.
• Storage: ~500 MB for full database + viewer.
• Software: If using raw .mdb file, you need Microsoft Access 2016+ or an ODBC driver to read it.

Developed by the American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE), this database is the digital companion to the fitting loss coefficients found in the ASHRAE Handbook—Fundamentals. It moves beyond static tables, offering dynamic calculation capabilities that streamline the HVAC design process. ASHRAE Duct Fitting Database Version 6

Technical Notes

• Version 6.00.05 is typically distributed as a standalone Windows executable or integrated into ASHRAE Handbook Online.
• The database replaces Version 6.00.04 and includes minor corrections to fitting loss coefficients for certain rectangular 45° wyes and reducing tees.
• Requires no additional license beyond ASHRAE membership or purchase (available via ASHRAE Bookstore).
