What Is the ASHRAE Duct Fitting Database?
The ASHRAE Duct Fitting Database is a digital repository of loss coefficients (C-values) for thousands of duct fittings. It is the electronic companion to the ASHRAE Handbook—Fundamentals and the HVAC Duct Construction Standards. Before this database, engineers relied on printed tables and manual interpolation—a time-consuming and error-prone process.
The database allows users to:
- Look up dynamic loss coefficients for specific fittings.
- Export data directly into Excel or CAD environments.
- Integrate with leading HVAC design tools like Trane Duct Designer, Carrier E20-II, Elite Software, and McQuay DuctSizer.
Version 60 refines this data with updated coefficients based on the latest ASHRAE research, including adjustments for high-velocity systems and non-standard duct materials.
