It is important to obtain the database through official channels.
Yes. While version 7.0 (paid) includes CFD-validated data for spiral flat-oval fittings, —rectangular, round, elbows, tees, and transitions.
The ASHRAE Duct Fitting Database, especially with the dynamic capabilities of Version 6.0, is far more than a simple lookup table. It is a professional-grade engineering tool that automates complex calculations, reduces the potential for design error, and significantly streamlines the process of creating efficient duct systems. It is important to obtain the database through
Many commercial HVAC loads and duct design programs (such as Carrier HAP, Trane Trace, or Wrightsoft) license ASHRAE data directly. If you already own high-end HVAC design suite licenses, check if the ASHRAE fitting database is already integrated into your existing toolset.
The ASHRAE DFDB v6.0 provides extensive loss coefficient tables for over 200 duct fittings. It is designed to assist in calculating the pressure drop across various components in supply, return, and exhaust systems, ensuring that HVAC designs meet the performance requirements laid out in the ASHRAE Handbook—Fundamentals . The ASHRAE Duct Fitting Database, especially with the
: Some loss coefficient data is available in PDF format through ASHRAE handbooks (e.g., Fundamentals ), but these do not offer the interactive calculation features of the standalone database . ASHRAE DFDB Lite - App Store - Apple
: Unauthorized versions cannot receive critical bug fixes, fitting updates, or official technical support. If you already own high-end HVAC design suite
The database provides, but is not limited to, the following for fittings:
No. The latest cloud version is 6.00.05; the most widely referenced desktop version is 5.00.10. There is no “Version 60” release. Any website advertising “Version 60” is likely using misleading labeling.
