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

kW — Compressor Motor Power Input ldb — Leaving Dry-Bulb

lwb — Leaving Wet-Bulb

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)

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 evaporator coil.

Below 80 F edb, subtract (corr factor x cfm) from SHC. Above 80 F edb, add (corr factor x cfm) to SHC.
