Ashrae Duct Fitting Database Version. 6.00.05 [updated] Link

★★★★½ (4.5/5) Reviewer Role: Mechanical Engineer / HVAC Designer

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

From its integration into BIM workflows to its availability as a mobile app, the DFDB ensures that engineers have access to the most accurate and up-to-date loss coefficient data, whether they are in a high-rise office building or on a construction site. For any professional involved in the design of air distribution systems, proficiency with the ASHRAE Duct Fitting Database is not just an advantage—it is a necessity. Its data, driven by rigorous standards like ASHRAE 120, forms the foundation for efficient, cost-effective, and high-performing HVAC systems in buildings around the world.

Understanding the evolution helps users appreciate the improvements in Version 6.00.05. According to ASHRAE’s own documentation, Version 5.0 included modifications to a substantial list of fittings, including: ashrae duct fitting database version. 6.00.05

: It supports both I-P (Imperial) and SI (Metric) units, allowing for global project applicability.

When using short-radius rectangular elbows, utilize the database to compare the pressure drop of the fitting with and without turning vanes. The reduction in fan energy often justifies the fabrication cost.

The ASHRAE Duct Fitting Database version 6.00.05 can be accessed through various platforms, including:

The utility of the DFDB lies in its comprehensive coverage of fitting types. Version 6.00.05 includes loss coefficient data for different fittings in three primary shapes: round , rectangular , and flat oval ducts. For mobile users, the DFDB app boasts coverage of 250+ fittings . These fittings are further categorized by their function:

Its primary function is to allow engineers to quickly and accurately calculate the pressure loss (K-value) for a specific duct fitting. By inputting parameters like flow rate and duct dimensions, users obtain precise loss coefficient data, replacing time-consuming manual lookups with automated, reliable results. Version 6.00.05 is delivered via a one-year cloud-based subscription, which can be accessed through both a web interface and a mobile app for iOS devices.

This version integrates the latest laboratory test data vetted by ASHRAE Technical Committee 5.2 (Duct Design). It features corrected entry data for highly complex fittings, such as specialized converging tees, asymmetric wyes, and close-coupled elbows. 2. Modern OS Compatibility
