Ashrae Duct Fitting Database Version 60005 [ macOS PRO ]
Users select the fitting from the categorized library (e.g., a 90° elbow).
ASHRAE Duct Fitting Database (DFDB) version 6.00.05 is a cloud-based design tool primarily used by engineers to calculate pressure losses and loss coefficients for over 200 HVAC duct fittings. Core Technical Features
Version 60005 isn't a flashy overhaul—it’s a precision tooling update. For the engineer trying to squeeze out 3% more efficiency from a duct system, or the modeler trying to clear a clash detection log, these small data corrections add up to real-world savings. ashrae duct fitting database version 60005
Version 6.00.05 represents a significant evolution in usability and data breadth over previous iterations like Version 5.0. Its core capabilities include:
Smooth radius elbows, mitered elbows, concentric/eccentric transitions, and conical tees. Users select the fitting from the categorized library (e
ΔPt=C×Pvcap delta cap P sub t equals cap C cross cap P sub v Pvcap P sub v is the velocity pressure at the point of interest. How to Use the Database for Design
Once you open version 60005, you will see a relational database with five primary tables. Understanding this structure is key to using the tool effectively. For the engineer trying to squeeze out 3%
While ASHRAE continuously updates its data, version 6.00.05 represents a refined, stable iteration designed for accuracy and user experience.
: Includes tables for supply, exhaust, and common (supply/return) functions. Real-Time Calculations
ASHRAE TC 5.2 (Duct Design) revisited the empirical data for common fittings, particularly and rounded rectangular elbows . Some coefficients changed by as much as 15% compared to previous versions, meaning designs based on older databases may be significantly under- or over-estimating pressure drop.
