Complemented by the Duct Fitting Database Lite App for field verification on iOS devices.
If you use AutoCAD MEP or Revit, the updated 60005 plugin fixes a persistent bug where dynamic pressure calculations would default incorrectly for metric (SI) workflows. The new version now passes the data model more cleanly, meaning fewer “Unknown Fitting” errors in your pressure drop reports.
As HVAC systems become more complex and energy efficiency standards rise, precision in duct design is more critical than ever. The is the industry-standard tool for calculating pressure losses in HVAC systems, and keeping up with its latest iterations—such as the advanced, cloud-based offerings—is essential for engineering professionals. ashrae duct fitting database version 60005
: C (Rectangular), S (Round/Circular), E (Flat Oval).
The interface allows users to enter flow rates and fitting dimensions to instantly obtain velocity, velocity pressure, and pressure loss. Complemented by the Duct Fitting Database Lite App
Using the DFDB is a straightforward process, designed to integrate seamlessly into an engineer's workflow:
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 As HVAC systems become more complex and energy
A university used the new oval duct fittings to squeeze a high-velocity system into a shallow ceiling plenum. Without accurate coefficients, they’d have oversized the fan by 20%.
