Ashrae Duct Fitting Database Version. 6.00.05 |top| Today
Enter the physical parameters, such as duct width ( ), height ( ), diameter ( ), or turning radius (
Many third-party HVAC design and BIM software packages (such as Autodesk Revit or Wrightsoft) build their native duct calculation engines to reference or sync with specific ASHRAE database versions.
Ability to export calculated loss coefficients directly to text files or spreadsheets for integration with master external calculation sheets. Technical Foundations: How the Database Works The software calculates total pressure loss (
Version 6.00.05 includes over , up from approximately 450 in version 5.x. New additions include: ashrae duct fitting database version. 6.00.05
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.
Search for specific fittings by code, geometric configuration, or custom keywords.
Over-sizing a fan leads to wasted energy and noisy systems, while under-sizing leads to poor indoor air quality and thermal discomfort. Version 6.00.05 allows for "right-sizing" by: Enter the physical parameters, such as duct width
Version 6.00.05 provides the exact empirical data required to size fans optimally, matching the true static pressure requirements of the system. Energy Efficiency and Building Code Compliance
To fully appreciate the impact of version 6.00.05, it is essential to understand what the DFDB is and why it is so important. Published by the American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE), the DFDB is a digital repository of loss coefficient tables for hundreds of duct fittings. It is the go-to resource for design engineers who need to calculate the pressure loss through fittings in various duct systems.
: New straight duct entries for round ducts, covering velocity-limited and constant equal friction scenarios. CD3-22 & CD3-23 New additions include: Each fitting in the database
This version features an intuitive graphical interface that simplifies navigation. Engineers can quickly search for fittings using standard ASHRAE alphanumeric codes (e.g., SD3-1 for a specific supply duct elbow). 3. Dynamic Calculation Engine
Open the application from your desktop. You’ll be greeted with an Explorer‑style view that organizes fittings by category and type.
