NOTES:
1. Direct interpolation is permissible. Do not
extrapolate.
2. The following formulas may be used:
Where: h
ewb
= Enthalpy of air entering evapo-
rator coil
3. The SHC is based on 80 F edb temperature of
air entering evaporator 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).
Bf — Bypass Factor
Edb — Entering Dry-Bulb
Ewb — Entering Wet-Bulb
kW — Compressor Motor Power Input
SHC — Sensible Heat Capacity (1000 Btuh) Gross
TC — Total Capacity (1000 Btuh) Gross
