The ASHRAE Duct Fitting Database 2016 offers several benefits to HVAC engineers, including:
The Duct Fitting Database is essentially an electronic standard reference. It allows engineers to enter data for a specific fitting—such as its geometry, dimensions, and airflow rate—and immediately obtain its Loss Coefficient ( Co ) and the resulting pressure drop [0†L5-L8]. This speed and accuracy are crucial, as manually determining these values from reference tables can be slow and prone to error. The database covers functions for hundreds of fitting configurations [0†L10-L11].
Over 200 distinct fitting geometries, including round, rectangular, and flat-oval ducts, with new entries for radiused elbows, conical reducers, and modern turning vanes. ashrae duct fitting database 2016
ASHRAE also offers a for iOS devices (iPhone and iPad), designed for quick field calculations.
The 2016 updates were instrumental in bridging the gap between desktop and mobile. The ASHRAE Duct Fitting Database App , developed by Carmel Software , allows field engineers to perform calculations on iPhones and iPads. The ASHRAE Duct Fitting Database 2016 offers several
: A free version providing a subset of the 240+ fittings for quick field checks.
While the DFDB is a single product, it's available in various forms to suit different needs and workflows. The database covers functions for hundreds of fitting
The ASHRAE Duct Fitting Database is a collection of data on various duct fittings, including elbows, tees, wyes, and transitions. The database provides a comprehensive list of duct fitting types, along with their corresponding pressure drop coefficients. This data is essential for HVAC engineers to accurately calculate the pressure drop in duct systems, which is critical for ensuring the proper performance and efficiency of HVAC systems.
In the complex world of HVAC design, precision is paramount. While sizing a main duct trunk might seem straightforward, the true test of an efficient system lies in the details: the elbows, the transitions, the takeoffs, and the dampers. These components, known as duct fittings, are the source of the greatest friction and turbulence in a system.
