The ASHRAE Duct Fitting Database (DFDB) is a specialized tool used by design engineers to calculate pressure losses in HVAC systems. While the 2016 version was a desktop-based application, it has since transitioned to a cloud-based subscription service offering loss coefficient tables for over 200 fitting types. 1.

: Users input duct dimensions, flow rates, and air properties (elevation, temperature) to obtain real-time pressure loss results.
. By accurately predicting pressure drops, engineers can design "low-pressure" systems that require smaller, more energy-efficient fans. This reduces the overall carbon footprint of a building and ensures that the indoor air quality remains consistent without excessive noise generated by overpowered air systems.

: Users can save selected fittings into a project file, which facilitates the calculation of total pressure drop along a "critical path" or the longest duct route. Units and Reporting : The software supports both
