Ashrae Duct Fitting Database Version 60005 ❲SAFE — HACKS❳

Includes data for over 200 to 240+ fittings spanning round, rectangular, and flat oval geometries.

Each fitting entry is identified by a unique number and is accompanied by a pictorial outline to aid in correct identification.

The DFDB includes loss coefficient tables for more than 200 round, rectangular, and flat oval duct fittings. The database covers a wide array of fitting categories for supply, exhaust, and common (supply/return) duct functions. The full library features over 240 fittings, including many types that are covered by the free "DFDB Lite" app to provide a representative sample: ashrae duct fitting database version 60005

: Dedicated configurations for different system sections.

Includes over 200 diverse fitting types, spanning round, rectangular, and flat oval geometries. Includes data for over 200 to 240+ fittings

The data provided is based on intensive research and testing, ensuring high accuracy in calculations. The Importance of Accurate Fitting Data

For context, the transition from brought numerous specific updates to fitting loss coefficient data across categories like CD, ED, ER, SD, and SR fittings, demonstrating ASHRAE's commitment to continuously refining the database. The database covers a wide array of fitting

The database serves as the digital companion to the ASHRAE Handbook—Fundamentals and ASHRAE Duct Design Guide . Instead of manually looking up tables and graphs, users can enter fitting parameters to calculate the pressure loss instantly. Why Use the Database?

The database provides the value. The user enters details like the fitting type, dimensions, flow rate, and air properties. The DFDB then automatically looks up the correct K-value and calculates the associated pressure loss in either I-P (Imperial) or SI (Metric) units.

The DFDB allows engineers to input specific geometric dimensions and volumetric flow rates ( CFMcap C cap F cap M ) to automatically calculate local loss coefficients ( Cocap C sub o ) and the resulting pressure drop ( Key Features and Enhancements in Version 6.00.05
