COOLING CAPACITIES LEGEND AND NOTES

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:

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.

Interpolation is permissible.

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

tlwb =	Wet-bulb temperature corresponding to enthalpy of air
	leaving evaporator coil (hlwb)
hlwb =	hewb –	total capacity (Btuh)
		4.5 x cfm

Where: hewb = Enthalpy of air entering evaporator coil
