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

t ldb = t edb −	sensible capacity (Btuh)
	1.10 x cfm

tlwb = Wet-bulb temperature corresponding to enthalpy of air leaving evaporator coil (hlwb)

hlwb = hewb −	total capacity (Btuh)
	4.5 x cfm

Where: hewb = Enthalpy of air entering evaporator coil

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).
