BF — Bypass Factor
Ewb — Entering Wet-Bulb
kW — Total Unit Power Input
SHC — Sensible Heat Capacity (1000 Btuh)
TC — Total Capacity (1000 Btuh) (net)
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).
