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

		total capacity
hlwb = hewb	–	(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 evaporator coil.

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

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