Ashrae Duct Fitting Database Excel //free\\ Jun 2026

Manually typing coefficients from the ASHRAE handbook defeats the purpose of automation. You can use advanced Excel lookup formulas to pull data based on fitting dimensions. 1. Two-Dimensional Lookups using XLOOKUP Many ASHRAE fittings determine Cocap C sub o

To create your own database or calculator in Excel, you need to extract the pertinent data from the ASHRAE handbook or the software. 1. Structure Your Spreadsheet Create a structured Excel sheet with the following columns: (e.g., CD3-1, RE5-1) Description (e.g., 90-degree round elbow) Key Dimensions (D, W, H, r/D) Loss Coefficient (C-factor) Velocity Pressure ( Pvcap P sub v ) Formula Pressure Loss ( ) 2. Implement the Formulas

To build a reliable duct fitting calculator in Excel, you must understand how ASHRAE categorizes fittings. The database uses a standardized alphanumeric coding system based on geometry and function. Fitting Categories and equipment pressure drops (coils

Excel allows designers to combine duct friction losses, fitting losses, and equipment pressure drops (coils, filters, dampers) into a single master schedule. Key Components of an Excel-Based Duct Calculation Tool
