What Is the Cooling Coil Apparatus Dew Point (ADP) & Bypass Factor (BF) Calculator?
Not all air passing through an air handling unit cooling coil makes direct contact with the chilled fin surfaces.
The bypass factor (BF) represents the fraction of air that slips through untouched without heat or moisture exchange.
