Version 6.00.05 builds upon previous analytical engines to deliver a more stable, versatile, and precise calculation environment. Expanded Fitting Portfolio
For decades, the industry standard for calculating these critical pressure losses has been the . With the release of Version 60005 , engineers, contractors, and BIM technicians have received a substantial update that refines how we model air distribution.
: It contains loss coefficient tables for over 200 types of fittings, including round, rectangular, and flat oval designs.
The database removes guesswork. It replaces "that feels right" with empirical, peer-reviewed fluid dynamics. By upgrading to version 60005 and integrating it into your BIM workflow, you ensure your pressure drop calculations align with the current state of the art in HVAC science. ashrae duct fitting database version 60005
: An updated graphical user interface accelerates the process of selecting inputs for converging and diverging tees, elbows, and entries.

The interface allows users to enter flow rates and fitting dimensions to instantly obtain velocity, velocity pressure, and pressure loss. Version 6
Duct fittings cause dynamic pressure losses due to friction and turbulence. The database provides a non-dimensional loss coefficient ( Cocap C sub o
The DFDB, particularly in its Version 6.00.05 iteration, provides a robust set of features that streamline the HVAC design workflow:
