Ashrae Duct Fitting Database Version 60005 [2021] Info
Enter geometric parameters such as duct width, height, diameter, angle of turns, and turning vane details.
Version 6.00.05 introduced critical software patches, database expansions, and fixed formula syntax errors found in earlier sub-versions like 6.00.04. 1. Added Fitting Profiles
Where (P_v) is the velocity pressure. Version 60005 is the latest iteration of this database, released to support ASHRAE’s Fundamentals Handbook and HVAC Duct Construction Standards .
This paper examines the structure, coefficients, and usage of the ASHRAE Duct Fitting Database (DFDB) version 60005. The DFDB provides loss coefficients ((C) or (C_o)) for hundreds of duct fittings based on laboratory testing, as documented in ASHRAE Research Project RP-1173. Version 60005 likely represents a specific data snapshot or update within the ASHRAE fitting library. We describe the database schema, coefficient extraction methods, comparison with earlier versions (e.g., 50004), and integration into energy simulation tools (e.g., EnergyPlus, Trane Duct Designer). Agreement with measured data is within ±15% for most fittings. Recommendations for quality assurance and version control are provided.
Supply, Exhaust, Common, Junctions, or Transitions Category: Elbows, Tees, Wyes, Entrances, or Outlets Understanding the Math: How Version 6.00.05 Calculates Loss
Double-check that your global settings are correctly toggled to either IP (Inch-Pound) or SI (International System) units before copying values over to design documents.
Minimizing installation costs, fan energy consumption, and system-generated noise.
Unlike freeware, the ASHRAE DFDB is a paid, copyrighted product. Here is the legitimate path to acquire version 60005.
: Dual-unit functionality allowing seamless switching between I-P (Inch-Pound) and SI (International System) units.
To help tailor further technical details about this database, let me know:
For the uninitiated: the DFDB is the digital home of experimentally derived loss coefficients (C₀, C₁, C₂) for thousands of duct fittings. Instead of guessing, you look up a fitting shape, input geometry, and get dynamic loss coefficients. It powers software like , Elite HVAC , and many in-house tools.
