NOTES:
1. Direct interpolation is permissible. Do not extrapolate.
2. The following formulas may be used:
t = t
ldb edb
t = Wet-bulb temperature corresponding to enthalpy of air leaving
lwb
evaporator coil (h
h = h
lwb ewb
Where: h = Enthalpy of air entering evaporator coil.
ewb
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).
