Ashrae Duct Fitting Database Version. 6.00.05 ((new)) -

The is the industry-standard software tool used by HVAC design engineers to accurately calculate static pressure losses across complex duct networks. Developed by the American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE), this specific version transitions the legacy desktop application into a high-utility, cloud-based subscription platform . It provides access to verified fluid dynamics equations and loss coefficients for over 200 round, rectangular, and flat oval duct fittings . Core Engineering Purpose: Calculating ESP

Expanded valid input ranges for various fittings, including transitions and elbows (e.g., , ER4-3 , CR3-17 , and CR9-3 ). 3. Engineering Application and Compliance

Designers use this database to determine , which is essential for selecting the correct fan or Air Handling Unit (AHU). The is the industry-standard software tool used by

Engineers rely on the database to size ducts, select appropriate fittings, and verify that total pressure losses remain within the fan’s external static pressure (ESP) capability. By using DFDB coefficients, designers can accurately predict system performance and avoid costly oversizing or undersizing.

ASHRAE Duct Fitting Database (DFDB) version 6.00.05 is the critical maintenance release of the version 6 software, widely used by HVAC engineers for calculating pressure losses in duct systems

Global engineering projects require seamless transitions between measurement systems. The software fully supports both: Access and Availability Duct Fitting Database - ASHRAE

) tables compiled from decades of mechanical laboratory research, this version ensures strict compliance with building codes and the ASHRAE Handbook—Fundamentals. Precise calculation of External Static Pressure (ESP) using this software prevents over-sizing or under-sizing critical commercial HVAC equipment like Air Handling Units (AHUs) and fans.
