Standard Ratings

LEGEND

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:

				sensible capacity
tldb	=	tedb	–	(Btuh)
				1.10 x cfm
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.

Correction Factor = 1.10 x (1 – BF) x (edb – 80).
