Ashrae Duct Fitting Database Version. 6.00.05 | TESTED 2024 |

Integration and ExportEngineers can export data for use in external spreadsheets or design reports. This makes it easier to document the "worst-case" path in a duct run, which is essential for sizing fans correctly and meeting building codes. Why Version 6.00.05 Matters for Energy Efficiency

The database is frequently used in HVAC engineering courses and research projects. For example, the DFDB coefficients have been employed in studies examining pressure losses across multiple interacting fittings and in the development of advanced duct design methods like the T‑method.

If you input a specific elbow (e.g., a short radius), the database could instantly display a side-by-side comparison with a long radius elbow or one with turning vanes. It would show the specific Static Pressure (SP) savings Life-Cycle Cost (LCC) Integration:

The data within the tool is structured alphabetically and numerically by fitting configuration: Duct Fitting Database - ASHRAE ashrae duct fitting database version. 6.00.05

Here’s a concise write-up on :

Version 6.00.05 includes over , up from approximately 450 in version 5.x. New additions include: Integration and ExportEngineers can export data for use

At 9:00 AM, she opened her duct sizing software and imported the file. Instead of hand-entering coefficients, she selected a 24" round 90-degree mitered elbow with three turning vanes. The database returned:

For decades, the industry standard for this purpose has been the . The release of version 6.00.05 represents a landmark update in this software’s history. This version is not merely a minor patch but a major evolutionary leap, fundamentally changing how engineers interact with, calculate, and integrate critical fitting data.

Each fitting in the database is identified by a (e.g., CD3-22, SR4-3). This systematic coding makes it easy to cross-reference with ASHRAE handbooks and ensures precise communication between engineers. The database also features pictorial outlines of each fitting, which is an invaluable feature for quickly identifying the correct geometry for a given design. For example, the DFDB coefficients have been employed

For mechanical engineers and HVAC designers, precision in calculating pressure loss is the difference between a high-performing system and an inefficient, noisy one. The ASHRAE Duct Fitting Database (DFDB) has long been the gold standard for this task. The Version 6.00.05

The journey of the DFDB from a simple CD-ROM to a cloud-based platform is a story of continuous improvement. The version history provided by Carmel Software shows a clear trajectory of refinement:

Navigate through the catalog of more than 200 fittings, or use the search function to locate a specific fitting by its ASHRAE number or description.
