The ASHRAE Duct Fitting Database (DFDB) Version 6.00.05 is a specialized engineering software tool used to calculate pressure losses for various HVAC duct fittings. It provides authoritative loss coefficient data based on the ASHRAE Handbook—Fundamentals. Core Functionality
If you are looking for a "helpful paper" or guide related to this version, the most authoritative resource is the ASHRAE Design Guide for Duct Systems.
Visual Aids: Pictorial outlines for each fitting to ensure accurate selection during the design process. ashrae duct fitting database version. 6.00.05
View input, output, and table data properties that update instantly as you adjust dimensions or flow rates. Dual Units: Full support for both I-P (Imperial) SI (Metric) Cloud-Based Access:
The ASHRAE Duct Fitting Database is not a standalone executable program but a structured data file. However, ASHRAE distributes it with a lightweight viewer/editor (ASHRAE DFDB Viewer, version 6.00.05 compatible). Here’s what you need: The ASHRAE Duct Fitting Database (DFDB) Version 6
is here. Version 6.00.05 refines the calculation engine for over 250+ duct fittings
Version 6.00.05 of the ASHRAE Duct Fitting Database includes several key features and enhancements, including: Visual Aids: Pictorial outlines for each fitting to
Always verify the fitting geometry. The database includes a diagram for each fitting ID. Do not guess by name alone. A "45° wye" can have throat radius, branch angle, and heel radius variations.
