Version 6.00.05 includes over , up from approximately 450 in version 5.x. New additions include:
Suppose a site measurement shows total static pressure 0.6 in. w.g. above design value. Using the database, you can systematically check each fitting's design C vs. as-built conditions. A common discovery: short-radius elbows installed instead of long-radius, raising C from 0.15 to 0.45.
Accurate pressure loss calculation is the foundation of efficient HVAC design. The ASHRAE Duct Fitting Database (DFDB) Version 6.00.05 stands as the industry-standard software application for engineers, designers, and balancing technicians seeking to precisely compute loss coefficients for a vast array of duct fittings. ashrae duct fitting database version. 6.00.05
The software uses the classic fluid mechanics pressure loss equation:
) tables compiled from decades of mechanical laboratory research, this version ensures strict compliance with building codes and the ASHRAE Handbook—Fundamentals. Precise calculation of External Static Pressure (ESP) using this software prevents over-sizing or under-sizing critical commercial HVAC equipment like Air Handling Units (AHUs) and fans. Version 6
Unlike older versions that required 32-bit Windows or legacy database drivers, Version 6.00.05 is fully compatible with:
: Locate the specific fitting code in the database that matches the layout geometry. above design value
The database contains all fitting types from ASHRAE’s research project RP-1493 and earlier RP-1243. New additions in this version include:
For mechanical engineers and HVAC designers, precision in calculating pressure loss is the difference between a high-performing system and an inefficient, noisy one. The ASHRAE Duct Fitting Database (DFDB) has long been the gold standard for this task. The Version 6.00.05
