BF — Bypass Factor Edb — Entering Dry Bulb Ewb — Entering Wet Bulb

kW — Compressor Motor Power Input

SHC — Sensible Heat Capacity (1000 Btuh) Gross TC — Total Capacity (1000 Btuh) Gross

NOTES:

1.Direct interpolation is permissible. Do not extrapolate.

2.The following formulas may be used:

tldb	= tedb	–	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.

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).
