The ASHRAE Duct Fitting Database (DFDB) version 6.00.05 is the current cloud-based software suite used by HVAC engineers to calculate pressure losses through various duct fittings

The ASHRAE Duct Fitting Database (DFDB) Version 6.00.05 is a cloud-based engineering tool providing loss coefficients for over 200 HVAC fittings to calculate External Static Pressure (ESP). It supports round, rectangular, and flat oval ducts, facilitating detailed pressure loss calculations and integration with BIM tools. For more details, visit Duct Fitting Database - ASHRAE

The ASHRAE Duct Fitting Database (DFDB) Version 6.00.05 is a critical software tool for HVAC engineers. It allows for the precise calculation of dynamic pressure losses across more than 200 fitting types.

Integration of new flexible elbow data (CD3-22, CD3-23) with varying radius ratios (

The ASHRAE Duct Fitting Database (DFDB) is a specialized engineering software designed to provide loss coefficient data for a wide variety of duct fittings. Version 6.00.05 is the current desktop/cloud iteration, distributed as a single-user annual subscription for cloud-based access. 1. Purpose and Application

At the heart of the ASHRAE Duct Fitting Database is the concept of the loss coefficient (C). Every elbow, tee, transition, and hood in a ventilation system introduces turbulence and friction, leading to a drop in total pressure. If an engineer overestimates these losses, they specify a fan that is too large, leading to wasted energy and excessive noise. If they underestimate, the system will fail to deliver the required airflow to the occupied spaces.

Version 6.00.05 provides a comprehensive library of these coefficients, derived from decades of laboratory testing and computational fluid dynamics (CFD) modeling. By using this validated data, designers can move away from "rule of thumb" estimations and toward high-fidelity system simulations. Key Features of Version 6.00.05

Getting access to the DFDB is a multi-path process depending on your needs and platform.
