NOTES:
1. Direct interpolation is permissible. Do not
extrapolate.
2. The following formulas may be used:
t
lwb
= Wet-bulb temperature corresponding
to enthalpy of air leaving indoor coil
(h
lwb
)
Where: h
ewb
= Enthalpy of air entering evap-
orator coil
3. The SHC is based on 80 F edb temperature
of air entering indoor coil.
Below 80 F edb, subtract (corr factor x cfm)
from SHC.
Above 80 F edb, add (corr factor x cfm) to
SHC.
Interpolation is permissible.
Correction Factor = 1.10 x (1 – BF) x
(edb – 80).
