		Standard Ratings

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:

t		=	t	–	sensible capacity (Btuh)
ldb			edb		1.10 x cfm
tlwb		= Wet-bulb temperature corresponding to enthalpy of
			air leaving evaporator coil (hlwb)
h	lwb	=	h	–	total capacity (Btuh)
			ewb		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. Correction Factor = 1.10 x (1 – BF) x (edb – 80).
