BF	Ð Bypass Factor
Edb	Ð Entering Dry-Bulb
Ewb	Ð Entering Wet-Bulb
kW	Ð Compressor Motor Power Input
Ldb	Ð Leaving Dry-Bulb
Lwb	Ð Leaving Wet-Bulb
SHC Ð Sensible Heat Capacity (1000 Btuh) Gross
TC	Ð Total Capacity (1000 Btuh) Gross

NOTES:

1.Direct interpolation is permissible. Do not extrapolate.

2.The following formulas may be used:

sensible capacity (Btuh)

tldb = tedb −

1.10 x cfm

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

total capacity (Btuh)

hlwb = hewb −

4.5 x cfm

Where: hewb = Enthalpy of air entering evaporator coil

3.The SHC is based on 80 F edb temperature of air entering evapo- rator 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).
