PERFORMANCE DATA (cont)
COOLING CAPACITIES, UNITS WITH PERFECT HUMIDITY™ OPTION
Do not operate at these conditions.
LEGEND
NOTES:
1. Direct interpolation is permissible. Do not extrapolate.
2. The following formulas may be used:
where hewb = enthalpy of air entering indoor coil
3. The SHC is based on 80 F edb temperature of air entering evaporator coil.
Below 80 F db, subtract (corr factor x cfm) from SHC.
Above 80 F db, add (corr factor x cfm) to SHC.
Correction Factor = 1.10 x (1 – BF) x (db – 80)
