Ashrae Duct Fitting Database Excel Link !!top!! Jun 2026

Open the ASHRAE DFDB application and configure your specific duct system parameters (e.g., fitting type, geometry, flow rate).

The ASHRAE Duct Fitting Database is a comprehensive repository of aerodynamic loss coefficients (loss factors or -factors) for a vast array of duct fittings. Why Fitting Coefficients Matter

Excel remains the undisputed Swiss Army knife for HVAC engineers. Integrating the ASHRAE DFDB data directly into an Excel ecosystem offers distinct engineering advantages.

: These industry-standard loads and duct tools can export comprehensive node-by-node duct pressure profiles directly into Excel-compatible reports. 3. Custom SQL or Access Database Queries ashrae duct fitting database excel link

This article explores the ASHRAE Duct Fitting Database, how to access it, and how to link its data into Excel for streamlined calculations. What is the ASHRAE Duct Fitting Database?

: This is a robust, free .xlsm tool from Titus that includes a dropdown menu for ASHRAE fitting codes and calculates pressure loss directly within Excel.

varies dynamically based on flow rates, aspect ratios, angle configurations, and velocity ratios, looking up these values manually for every single fitting in a large building network is incredibly time-consuming. The Value of an Excel Link for HVAC Engineers Open the ASHRAE DFDB application and configure your

The latest version (6.00) is accessed via a one-year subscription, ensuring access to the most up-to-date data.

The database covers:

Ensure your Excel sheet correctly interprets the pulled data using standard fluid mechanics formulas: Integrating the ASHRAE DFDB data directly into an

If you want to build or troubleshoot your integration, tell me:

No database contains every unique architectural fitting. Create a clear protocol in your spreadsheet for overriding or manually inputting custom loss coefficients (e.g., manufacturer-certified proprietary dampers or fire dampers) without breaking the automated ASHRAE link chains. Maximizing Fan Efficiency Through Accurate Data

Diameter for round or Width/Height for rectangular. Velocity (v): Air velocity in FPM or m/s.

Link fitting coefficients directly to your duct segment schedules to automatically calculate cumulative pressure drops.
