Engineers use the DFDB primarily to determine the of a duct system. Duct Fitting Database - ASHRAE : Used where space constraints limit rectangular or
Save fittings into a project file, which is easily navigated, stored, and transferred. This allows engineers to maintain calculation records across multiple design iterations.
Fan selection is heavily dependent on total static pressure. If an engineer underestimates the pressure loss from fittings, the selected fan will operate at a higher speed than intended to meet airflow requirements. This pushes the fan to the right on its performance curve, often resulting in higher noise levels and increased energy use. The DFDB helps ensure the initial fan selection is accurate, mitigating acoustical issues downstream. The ASHRAE Duct Fitting Database 2016 can be
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:
Using the ASHRAE Duct Fitting Database 2016 is relatively straightforward. Here are the general steps:
In an era where energy codes (such as ASHRAE 90.1) are increasingly stringent, "guessing" fitting losses is no longer acceptable. A standard mitered elbow without turning vanes has a significantly higher loss coefficient than a stamped radius elbow. The DFDB allows engineers to quantify this difference, justifying the specification of higher-quality fittings to reduce system static pressure and fan energy consumption.
