While Version 6.00.05 functions as a standalone desktop utility, its underlying data structure is highly integrated into modern Building Information Modeling (BIM) tools.
Using accurate data is critical because standard friction charts designed for sheet metal may not accurately reflect the performance of flexible ducts or fiberglass duct board
Users select the fitting from the categorized library (e.g., a 90° elbow). ashrae duct fitting database version 60005
The version 6.00.05 is a comprehensive tool designed to help HVAC engineers and designers calculate pressure loss across a wide variety of duct fittings. Version 6.00.05, released as a single-user product, introduced several critical updates to round and flexible duct fittings, as well as range increases for common input parameters. Key Features of Version 6.00.05
The engineering core of the ASHRAE Duct Fitting Database revolves around fluid dynamics calculations inside closed conduits. When air moves through an HVAC system, it encounters friction from straight duct walls and localized turbulence caused by directional changes, expansions, or contractions. While Version 6
Users can save fittings into project files that are easily stored, transferred, and navigated through pop-up windows.
Instead of relying on outdated, static tables, the DFDB provides detailed, graphically represented data that allows engineers to accurately calculate pressure drop across various fitting types in round, rectangular, and flat oval ducts. Key Features of Modern DFDB (Version 6.00.05 and Later) Version 6
: Users can enter specific flow rates and fitting dimensions to instantly obtain loss coefficient data and associated pressure losses.
During the design phase of an air distribution system, engineers must calculate the total pressure drop across the longest or most restrictive duct run (the critical path). This calculation determines the static pressure requirement for the supply, return, or exhaust fans.

With over 200 fittings available, finding the exact configuration can be time-consuming. The version 6.00.05 interface includes advanced filtering. Users can narrow down fittings by: Round, Rectangular, or Flat Oval
