Ashrae Duct Fitting Database Excel Link Access

Every fitting is backed by rigorous laboratory testing and engineering research. This makes it the global standard for commercial and industrial duct system pressure loss calculations. Why Connect the ASHRAE Database to Excel?

Ensure all open programs are closed—including those minimized on the taskbar. Then reinstall the program and reboot your computer.

The ASHRAE Duct Fitting Database, often referred to as the DFDB, is a comprehensive, electronic database of loss coefficient tables for over 200 different round, rectangular, and flat oval duct fittings.

The ASHRAE DFDB contains loss coefficient data for over 200 round, rectangular, and flat oval duct fittings. ashrae duct fitting database excel link

The ultimate goal of linking your ASHRAE database to Excel is precise fan sizing. Oversizing fans due to conservative, guessed fitting coefficients leads to inflated capital costs, continuous energy waste, and acoustic issues within occupied spaces. Conversely, undersizing results in poor indoor air quality and inadequate thermal comfort.

To effectively use an ASHRAE duct fitting link in Excel, you must have the following data points ready:

Integrating the ASHRAE Duct Fitting Database with Microsoft Excel bridges the gap between official data and automated Engineering workflows. Understanding the ASHRAE Duct Fitting Database The ASHRAE DFDB is a compilation of loss coefficients ( Cocap C sub o Every fitting is backed by rigorous laboratory testing

The ASHRAE Duct Fitting Database is a comprehensive repository of aerodynamic performance data for HVAC duct fittings. It contains loss coefficient factors ( Cocap C sub o ) for hundreds of fittings, including: Supply, return, and exhaust configurations. Round, rectangular, and flat oval geometries. Junctions, elbows, transitions, fan connections, and hoods.

This is not a "plug-and-play" black box software like some dedicated ductulators (e.g., Elite CHVAC). It requires a solid understanding of Excel. You are essentially building your own calculator using their engine. If you aren't comfortable with Excel formulas or VBA, the learning curve is steep.

While there is no single, official provided directly by ASHRAE, the data can be utilized effectively within Excel. Purchasing the official software allows for the most robust integration, while manufacturer calculators like the Titus SRG Calculator can provide quick, free solutions for common fittings.

While the official software isn't a native Excel file, most HVAC pros use the DFDB to pull accurate
