NOTES:
1. Ratings are net; they account for the effects
of the evaporator-fan motor power and heat.
2. Direct interpolation is permissible. Do not extrapolate.
3. The following formulas may be used:
sensible capacity (Btuh)
t
= t
؊
ldb
edb
1.10 x cfm
t
= Wet-bulb temperature corresponding to enthalpy of air leaving
lwb
evaporator coil (h
)
lwb
total capacity (Btuh)
h
= h
؊
lwb
ewb
4.5 x cfm
Where: h
= Enthalpy of air entering evaporator coil
ewb
4. 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)
