Work seamlessly in SI or Imperial units, with built-in conversions.
Over the years, the DFDB has been distributed in multiple formats. In the 2016 era, the primary ways to access the resource were:
The fundamental equation for calculating the pressure loss through a duct fitting is:
) from the ASHRAE Database, you can manually calculate the total pressure loss ( ΔPcap delta cap P ) using the following formula:
Versions 5.x were often distributed as traditional software installers. The 2016 era marked a transitional period, as version 6.00.05 began offering a cloud-based access subscription model.
The ASHRAE Duct Fitting Database is a collection of data that represents the pressure drop characteristics of various duct fittings, such as bends, tees, wyes, and reducers. The database provides engineers with the necessary information to accurately calculate the pressure drop in duct systems, which is essential for designing efficient and effective HVAC systems. The database contains data for a wide range of duct fittings, including those with complex geometries and configurations.
