Ashrae Duct Fitting Database Pdf Patched Here

By: Technical Standards Team

You need the pressure loss coefficients (C-factor or loss coefficients) for complex duct fittings to perform accurate duct design or energy modeling. But the software tools that unlock the official ASHRAE Database are expensive, and the database itself is often locked behind a paywall or proprietary software like ASHRAE’s official "Duct Fitting Database" (DFDB) or Trane Ductulator. ashrae duct fitting database pdf patched

The is the industry gold standard for loss coefficients for HVAC air distribution systems. It is based on decades of laboratory testing conducted at Texas A&M University and other research facilities. The data is published in ASHRAE’s Handbook—Fundamentals (Chapter 34) , but the comprehensive digital database includes over 200 fittings with detailed geometries.
