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