*At 75 F entering dry bulb (Tennessee Valley Authority [TVA] rating conditions); all
others at 80 F entering dry bulb.
NOTES:
1. Direct interpolation is permissible. Do not extrapolate.
2. The following formulas may be used:

Where:
h
= 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.
62
Above 80 F edb, add (corr factor x cfm) to SHC.
Correction Factor = 1.10 x (1 − BF) x (edb − 80).
