Standard Ratings
BF
— Bypass Factor
Edb — Entering Dry-Bulb

TC
— Total Capacity (1000 Btuh) Gross
NOTES:
1. Direct interpolation is permissible. Do not
extrapolate.
2. The following formulas may be used:
t
=
t
ldb
edb
t
=
Wet-bulb temperature
lwb
corresponding to enthalpy
of air leaving evaporator
coil (h
h
=
h
lwb
ewb
Where: h
= Enthalpy of air entering
ewb
evaporator coil
3. The SHC is based on 80 F edb tempera-
ture of air entering evaporator coil.
62
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).
