Ashrae Duct Fitting Database Version. 6.00.05 Now
Within two hours, Maria had modeled the entire air distribution system for floors 12 through 20 — a task that would have taken two days with the old method. But the real payoff came during the .
: Input the volumetric airflow rate (CFM or L/s) for each branch of the fitting.
: It is the standard software for determining External Static Pressure (ESP) required for proper fan and equipment selection.
Specific categories for elbows, transitions, junctions, obstructions, and fan inlets/outlets. ashrae duct fitting database version. 6.00.05
Includes round straight duct options (CD11-4 for constant equal friction and CD11-3 for velocity limited) and flexible elbows (CD3-22 and CD3-23). Expanded Input Ranges: The allowable range for physical dimensions like height ( ), width ( ), and length (
Invest the time to learn its hierarchy, integrate it into your software stack, and always cross-check the reference velocity. In the high-stakes world of modern building design, guesswork is a liability—and Version 6.00.05 is your hedge against it.
When existing systems suffer from poor airflow in specific zones, testing and balancing (TAB) technicians use the database to analyze existing fittings. Identifying high-loss restrictions allows teams to target specific fittings for field modification. Step-by-Step Workflow for Designers Within two hours, Maria had modeled the entire
When air flows through a duct system, it encounters resistance caused by friction against the duct walls and dynamic losses through fittings such as elbows, tees, transitions, and junctions. The DFDB allows engineers to select specific fittings, input design parameters (such as dimensions and flow rates), and instantly retrieve the appropriate loss coefficient ( Cocap C sub o ) and pressure drop values.
ASHRAE Duct Fitting Database Version 6.00.05: The Ultimate Guide to Precision HVAC Design
Using the ASHRAE DFDB Version 6.00.05 is straightforward, even for complex systems: : It is the standard software for determining
: Users enter flow rates and fitting dimensions to automatically obtain loss coefficient data and associated pressure loss Functional Categories : Organized by duct function, including supply, exhaust, and common (supply/return) Project Management
If your projects are small residential systems with simple round ducts, you may not need the full database—but the viewer is still faster than flipping pages.
