Engineers often use the software to calculate individual pressure drops for each fitting (in Pascals or inches w.g.) and then manually transfer these values into an Excel-based ESP Calculation Sheet to sum the total system losses.
The ASHRAE Duct Fitting Database (DFDB) is a comprehensive digital library used by HVAC engineers to calculate pressure losses across more than 200 types of round, rectangular, and flat oval fittings. While the core database is provided as a or a mobile app, many professionals integrate this data into Excel spreadsheets to perform the total External Static Pressure (ESP) calculations required for sizing fans and air handling equipment.
