NOTES:
1. Direct interpolation is permissible. Do
not extrapolate.
2. The following formulas may be used:
t
lwb
= Wet-bulb temperature corre-
sponding to enthalpy of air
leaving indoor coil (h
lwb
)
Where: h
ewb
= Enthalpy of air enter-
ing evaporator coil
3. The SHC is based on 80 F edb tem-
perature 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.
