Q: What are the benefits of using the ASHRAE Duct Fitting Database 2016? A: The database provides accurate loss coefficients, which help engineers and designers optimize duct system design, reduce energy consumption, and ensure that HVAC systems operate efficiently and effectively. ashrae duct fitting database 2016
Save fittings into a project file, which is easily navigated, stored, and transferred. This allows engineers to maintain calculation records across multiple design iterations.
) tables that allow engineers to calculate dynamic pressure loss using the formula: By providing accurate and comprehensive data on duct
The foundation of this effort was ASHRAE Standard 120—initially published in 1999, with the formalizing uniform laboratory test methods for determining flow resistance. This standard ensures that every fitting in the database was tested the same way, so engineers can trust that loss coefficients are comparable and consistent across all manufacturers.
Before computers, each major duct manufacturer developed its own proprietary catalogs of fitting performance data. Different companies used different test methods, and dimensions varied between them. For high-pressure systems, even small differences in claimed loss coefficients could significantly impact system performance. This fragmentation made it difficult for engineers to compare designs across manufacturers and led to unreliable pressure drop estimates. A: The database provides accurate loss coefficients, which
This database is not free . It was sold by ASHRAE as a paid product (Product Code: 98056). As of 2025–2026, it has been superseded by the ASHRAE Duct Fitting Database (2020) or integrated into tools like ASHRAE Handbook Online and McQuay Duct Sizer .
