COOLING CAPACITIES — UNITS WITH PERFECT HUMIDITY™ ADAPTIVE DEHUMIDIFICATION SYSTEM OPTION (cont)
LEGEND
*Negative SHC value indicates that the air entering the coil is being heated.
NOTES:
1. Direct interpolation is permissible. Do not extrapolate.
2. The following formulas may be used:
Where: h
ewb
= Enthalpy of air entering evaporator 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).
