| Problem | Solution | |--------|---------| | The database returns a "Division by zero" error for very low velocity. | Version 6.00.05 sets a minimum velocity floor of 150 fpm to avoid exaggerated C₀ correlations. Adjust your system minimum. | | My fitting isn’t listed (e.g., custom 37.5° lateral). | Use interpolation between 30° and 45° fittings. Version 6.00.05 includes interpolation guidance in the user manual. | | Loss coefficient seems too low for a transition. | Check the reference velocity. Transitions often use V₂ (smaller side), giving lower C₀ but higher Pv. | | Can’t open .mdb on macOS. | Use a third-party ODBC driver (e.g., ActualTech) or convert to SQLite using a Windows VM. |
Global engineering projects require seamless transitions between measurement systems. The software fully supports both: ashrae duct fitting database version. 6.00.05
Beware of “free downloads” online—they often contain corrupted files or earlier version (v4.0) with outdated coefficients. | Problem | Solution | |--------|---------| | The
ASHRAE Technical Committee TC 5.2 (Duct Design) has announced that Version 6.00.05 will likely be the last standalone database release. Future iterations will be integrated directly into the and real-time design calculators. However, version 6.00.05 will remain the validated baseline for at least the next 5–7 years. | | My fitting isn’t listed (e
Rumored features for v7 (anticipated 2027) include:
: Access to over 200–250+ unique round, rectangular, and flat-oval duct fittings. New Fittings : Added specific components including:
