The ASHRAE Duct Fitting Database Lite is a free app for iOS that allows for quick field calculations for common fittings.
Use the built-in report generator to export the data.
The database allows engineers to input specific dimensions and flow rates to receive an accurate dynamic loss coefficient ( Cocap C sub o ashrae duct fitting database excel link
While the standalone ASHRAE Duct Fitting Database (DFDB) desktop application is a staple in the industry, integrating this data directly into Microsoft Excel transforms how engineers approach calculations. Linking ASHRAE duct fitting data with Excel automates workflows, reduces manual entry errors, and accelerates the design of complex commercial HVAC systems.

Coefficients change based on velocity, flow ratios, and geometric dimensions. Methods to Link ASHRAE DFDB with Excel
The ASHRAE Duct Fitting Database Excel file can be downloaded from the ASHRAE website. The database contains a collection of duct fitting loss coefficients, which are essential for designing and analyzing HVAC duct systems. The database is in Excel format, making it easy to use and accessible to a wide range of users. Linking ASHRAE duct fitting data with Excel automates
The ASHRAE Duct Fitting Database is an indispensable tool for mechanical engineers and HVAC designers. While the core data has been the gold standard for decades, the ability to link it directly to Microsoft Excel transforms it from a static reference manual into a dynamic calculation engine.
