Ashrae: Duct Fitting Database Excel
The ASHRAE Duct Fitting Database Excel: A Comprehensive Tool for HVAC Design
Advantages of an Excel Format
: Use design drawings to find the longest duct route or the path with the most fittings. Tag Components
- Build manually – Transcribe from Handbook tables (time-consuming but precise).
- Third-party sources – Some engineering sites and GitHub repositories offer curated Excel files (check license and accuracy).
- Convert from official CD – If you have the ASHRAE Duct Fitting Database (CD or download), you can export tables to CSV then to Excel.
Manual Entry:
Engineers often use the software to calculate individual pressure drops for each fitting (in Pascals or inches w.g.) and then manually transfer these values into an Excel-based ESP Calculation Sheet to sum the total system losses. ashrae duct fitting database excel
