The ASHRAE Duct Fitting Database is an essential tool for HVAC engineers, providing numerous benefits, including:
Engineers rarely use the DFDB in isolation. Version 6.00.05 supports clean data exporting (often via CSV or text formats), allowing integration into third-party spreadsheet tools or external HVAC load calculation programs. How Version 6.00.05 Improves HVAC Workflows
: The interface allows for immediate calculation updates as data is entered, with fully viewable input/output properties. ashrae duct fitting database version 60005
In mechanical, electrical, and plumbing (MEP) engineering, precision in HVAC design is paramount. Calculating the pressure drop across a ductwork system determines the size of fans, energy consumption, and overall indoor air quality.
Z-shaped elbows, vaned elbows, obstructions, and converging/diverging take-offs. The ASHRAE Duct Fitting Database is an essential
The (often referred to as the DFDB ) is a comprehensive digital catalog of loss coefficients for hundreds of duct fittings. It is developed and maintained by ASHRAE (American Society of Heating, Refrigerating and Air-Conditioning Engineers), the premier organization for HVAC technology and standards.
A key aspect of version 6.00.05 is its cloud-based access model. Purchasers receive a to the web-hosted version of the database. This transition moves away from the physical CD-ROMs of the past toward a modern, always-accessible service. However, it's crucial to note that this version is designated as a single-user product, and multiple-user licensing is not available. In addition to the full version, ASHRAE also offers a free ASHRAE Duct Fitting Database Lite app on the Apple App Store, which allows users to perform pressure loss calculations for a subset of the 240+ ASHRAE fittings for quick, on-the-go estimates.
