NOTES:
1. Direct interpolation is permissible. Do not extrapolate.
2. The following formulas may be used:
where h
ewb
= enthalpy of air entering indoor coil
3. The SHC is based on 80 F edb temperature of air entering evaporator coil.
Below 80 F db, subtract (corr factor x cfm) from SHC.
Above 80 F db, add (corr factor x cfm) to SHC
.
Correction Factor = 1.10 x (1 – BF) x (db – 80)
