NOTES:
1. Net capacities shown include a deduction for evaporator fan motor heat.
2. Contact manufacturer for cooling capacities at conditions other than
shown in table.
3. Formulas:
Leaving db = entering db —
Leaving wb = wb corresponding to enthalpy of air leaving coil (h
lwb
)
h
lwb
= h
ewb
—
where h
ewb
= enthalpy of air entering coil.
4. Direct interpolation is permissible. Do not extrapolate.
5. SHC is based on 80°F db temperature of air entering coil. Below 80°F
subtract (corr factor x CFM) from SHC.
Above 80°F db, add (corr factor x CFM) to SHC.
SHC CORRECTION FACTOR
Interpolation is permissible.
Correction Factor = 1.09 x (1 – BF) x (db – 80)
