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).
