Ashrae Duct Fitting Database Version. 6.00.05 [better] -

For residential applications, designers often supplement this data with the ACCA Manual D standard.

The ASHRAE Duct Fitting Database (DFDB) version 6.00.05 is a specialized software tool and reference set used by HVAC design engineers to calculate pressure losses in air distribution systems. ashrae duct fitting database version. 6.00.05

: Ability to save multiple fittings into a project file for easy navigation and storage. Dual Units : Supports both I-P (Imperial) SI (Metric) Dual Units : Supports both I-P (Imperial) SI

The ASHRAE Duct Fitting Database is a comprehensive digital catalog of resistance coefficients (K‑values) for hundreds of standard duct fittings. It includes detailed loss coefficient tables for more than , each accompanied by a clear pictorial outline. For any given fitting, engineers enter the flow rate and relevant dimensional data, and the software instantly returns the loss coefficient along with the associated pressure drop. The journey of the DFDB from a simple

The journey of the DFDB from a simple CD-ROM to a cloud-based platform is a story of continuous improvement. The version history provided by Carmel Software shows a clear trajectory of refinement:

Enter the required dimensional parameters, such as the throat radius ratio ( ) or aspect ratio ( ). Input the flow ratio ( ) if calculating a branch fitting. Step 4: Extract the Results
