Ashrae Duct Fitting Database — Excel Link

The ASHRAE DFDB Lite App and the full iOS version allow users to generate reports. These reports often include a that can be emailed and opened on a desktop, providing a raw data link for further analysis. 3. Third-Party Excel Calculators

Users can input parameters such as flow rate, velocity, and geometry to instantly obtain the loss coefficient ( K -value) and associated pressure loss. Early versions were distributed on CD-ROM (e.g., Version 5.00.00), but modern access has shifted to cloud-based subscription models (Version 6.00.05).

Function GetAshraeCoefficient(FittingID As String, Ratio1 As Double, Ratio2 As Double) As Double ' Code to query the database/API based on Fitting ID and geometric ratios ' Returns the exact Co value End Function Use code with caution. Step 3: Map the Equations

Whether using the full desktop software or the Lite mobile app, the calculation process follows a standardized workflow.

Achieving a functional link between ASHRAE's validated data and Excel depends on the specific version of the software you own and your internal engineering toolset. 1. Using the Official ASHRAE DFDB Desktop Export Feature ashrae duct fitting database excel link
