Instead of manually reading complex logarithmic charts (like Chart 14-3 or 14-4 from the 1997 Handbook), the digital database allows engineers to compute dynamic losses instantly using standardized formulas: ( \Delta p = C_o \times P_v ) (where ( P_v ) is velocity pressure).
=GetLossCoefficient(401, 1.5, 0, 0) → returns Co for a 90° elbow with r/D=1.5. ashrae duct fitting database excel link
This is not a "plug-and-play" black box software like some dedicated ductulators (e.g., Elite CHVAC). It requires a solid understanding of Excel. You are essentially building your own calculator using their engine. If you aren't comfortable with Excel formulas or VBA, the learning curve is steep. Instead of manually reading complex logarithmic charts (like
: Includes data for supply, exhaust, and common duct functions with pictorial outlines for easy identification. It requires a solid understanding of Excel
: The interface allows for real-time calculation updates as input values are changed. Standards Compliance
