The ASHRAE Duct Fitting Database (DFDB) is a software‑based catalog of resistance coefficients for standard HVAC duct fittings—elbows, transitions, tees, offsets, and many other configurations [6†L12-L14]. By feeding in duct geometry and airflow data, users instantly obtain the fitting’s loss coefficient and the resulting pressure drop. This replaces slow manual table look‑ups and reduces the risk of calculation errors. After first launch
