Ashrae Duct Fitting Database 2016 Jun 2026

) from the ASHRAE Database, you can manually calculate the total pressure loss ( ΔPcap delta cap P ) using the following formula:

The database is organized into (Table 21-1 in ASHRAE Fundamentals). Examples:

While the 2016 edition maintains compatibility with legacy spreadsheet formats, it is optimized for direct import into HVAC load/energy simulation software (e.g., EnergyPlus, OpenStudio, HAP). ashrae duct fitting database 2016

Note: ASHRAE released a cloud-based API for the database in 2018, but the core 2016 dataset remains the reference standard for most BIM and Revit families.

Users enter data such as flow rate (CFM or L/s), duct dimensions (height, width, or diameter), and fitting geometry (radius ratio, angle). ) from the ASHRAE Database, you can manually

: Includes fittings for round, rectangular, and flat oval duct geometries.

ASHRAE Duct Fitting Database (DFDB) is a critical tool for HVAC design engineers, providing the precise data needed to calculate pressure losses within air distribution systems. By the time of the 2016 updates, the database had established itself as an industry standard for ensuring system efficiency and proper fan sizing. Precision in HVAC Design Users enter data such as flow rate (CFM

This database is the industry standard for calculating pressure loss (dynamic loss) through duct fittings in HVAC systems. The 2016 update was significant, introducing new fittings, correcting legacy data, and integrating with modern design software.
