Standard Ratings

LEGEND

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:

t ldb	= t edb – sensible capacity (Btuh)
		1.10 x cfm
tlwb	= Wet-bulb temperature corresponding to enthalpy of air leaving evapora-
	tor coil (hlwb )
hlwb	=hewb –	total capacity (Btuh)
		4.5 x cfm

Where: h ewb = 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.
