Ashrae Duct Fitting Database 2016 Here
ASHRAE Duct Fitting Database (DFDB)
The is a critical digital resource for HVAC engineers, providing standardized loss coefficient tables for over 200 types of duct fittings . The 2016 timeframe marked a period of significant transition between Version 5.0 and the newer, cloud-based Version 6.0, which streamlined how designers calculate External Static Pressure (ESP) and optimize airflow in commercial and industrial systems. Core Functionality of the Database
Featuring pictorial outlines of each fitting, this database is useful to design engineers dealing with a variety of duct fittings. ASHRAE Duct Fitting Database Lite App - ASHRAE ashrae duct fitting database 2016
- Expanded Fitting Library: Added over 50 new fittings, including modern compact elbows and high-efficiency turning vanes found in green building designs.
- Revised Loss Coefficients: Updated (C) values for spiral flat oval (SFO) fittings, reflecting manufacturing improvements.
- Digital Integration: Launched compatibility with major HVAC design software (e.g., Trane Duct Designer, Elite Software, and AutoCAD plugins).
- Metric and Imperial Units: Seamless toggling between I-P (inches, CFM) and SI (mm, L/s) units.
- Better Reynolds Number Correction: Provided more granular adjustments for low-pressure systems (e.g., residential), which suffer from laminar or transitional flow.

The 2016 updates were instrumental in bridging the gap between desktop and mobile. The ASHRAE Duct Fitting Database App , developed by Carmel Software , allows field engineers to perform calculations on iPhones and iPads. Expanded Fitting Library: Added over 50 new fittings,

To illustrate, let’s design a supply duct with a (C1-9). Using the ASHRAE Duct Fitting Database 2016 , here is the step-by-step process:
- ASHRAE Bookstore (Digital Download): Often sold as part of the Fundamentals Handbook CD/DVD 2016 (discontinued, but PDF copies circulate among members).
- Academic Libraries: Many university engineering libraries retain a licensed copy on institutional servers.
- Third-Party HVAC Software: Purchasing Elite or Wrightsoft grants you access to the embedded 2016 coefficients.
- Legacy Media: eBay or engineering forums occasionally list the original ASHRAE Duct Fitting Database 2016 CD-ROM.
- Expanded content: The database now includes over 300 duct fittings, with 100 new entries compared to the previous edition.
- Improved data accuracy: The loss coefficients have been re-evaluated and updated to reflect the latest research and experimental data.
- Enhanced search functionality: The database is searchable by fitting type, size, and other parameters, making it easier to find specific fittings.
- SI and I-P units: The database provides loss coefficients in both SI (International System of Units) and I-P (Inch-Pound) units.
