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