The ASHRAE Duct Fitting Database (DFDB) is the industry-standard reference for designing and analyzing ductwork systems. It provides the loss coefficients ($C$-values) required to calculate pressure losses for various duct fittings (elbows, transitions, take-offs, etc.).
Historically, engineers relied on the charts and tables printed in the ASHRAE Fundamentals Handbook. Today, the database is primarily maintained as a digital application. ashrae duct fitting database excel link
The purchased ASHRAE DFDB software includes features designed to bridge the gap with Excel. The ASHRAE Duct Fitting Database (DFDB) is the
If you’ve ever spent hours manually calculating pressure drops through elbows, transitions, or tees, you know the pain. We all rely on the ASHRAE Fundamentals Handbook (Chapter 34, to be precise) for those loss coefficients. But flipping through pages or scanning PDFs is tedious. ashrae duct fitting database excel link
That’s where the ASHRAE Duct Fitting Database (DFDB) comes in. And the million-dollar question is: Is there a direct Excel link?
Let’s cut through the noise and show you how to connect Excel to the most powerful duct fitting library on the planet.
