NOTES:
1. Direct interpolation is permissible. Do not extrapolate.
2. The following formulas may be used:
t ldb = tedb −
sensible capacity (Btuh)
1.10 x cfm
t lwb = Wet-bulb temperature corresponding
evaporator coil (h lwb )
to enthalpy of air leaving
h lwb = hewb −
total capacity (Btuh)
4.5 x cfm
Where: h ewb = Enthalpy of air entering evaporator coil
3. The SHC is based on 80 F edb temperature of air entering evaporator 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).
