Using the ASHRAE Duct Fitting Database is relatively straightforward. Here are the general steps: Compare this version's to an older version

The interface allows for dynamic input of dimensions and flow rates, with pressure loss results updating instantly. Here are the general steps: The interface allows

Version 6.0.005 includes a broader array of fittings, specifically targeting non-standard geometries. This includes updates to:

This paper examines the structure, coefficients, and usage of the ASHRAE Duct Fitting Database (DFDB) version 60005. The DFDB provides loss coefficients ((C) or (C_o)) for hundreds of duct fittings based on laboratory testing, as documented in ASHRAE Research Project RP-1173. Version 60005 likely represents a specific data snapshot or update within the ASHRAE fitting library. We describe the database schema, coefficient extraction methods, comparison with earlier versions (e.g., 50004), and integration into energy simulation tools (e.g., EnergyPlus, Trane Duct Designer). Agreement with measured data is within ±15% for most fittings. Recommendations for quality assurance and version control are provided.

More fittings, lower losses, and fewer excuses for “guesstimating” pressure drops.
