Direct interpolation is permissible. Do not extrapolate.2. The following formulas may be used:sensible capacity (Btuh)tldb = tedb – 1.10 x cfmtlwb = Wet-bulb temperature corresponding to enthalpy of airleaving indoor coil (hlwb)total capacity (Btuh)hlwb = hewb – 4.5 x cfmWhere: hewb = Enthalpy of air entering evaporator coil3. The SHC is based on 80 F edb temperature of air entering evapo-rator coil.Below 80 F edb, subtract (corr factor x cfm) from SHC.Above 80 F edb, add (corr factor x cfm) to SHC.Correction Factor = 1.10 x (1 – BF) x (edb – 80).9
