BF — Bypass Factor Edb — Entering Dry-Bulb Ewb — Entering Wet-Bulb

kW — Compressor Motor Power Input

SHC — Gross Sensible Heat Capacity (1000 Btuh) TC — Gross Total Capacity (1000 Btuh)

NOTES:

1.Direct interpolation is permissible. Do not extrapolate.

2.The following formulas may be used:

sensible capacity (Btuh)

tldb = tedb –

1.10 x cfm

tlwb = Wet-bulb temperature corresponding to enthalpy of air leav- ing indoor coil (hlwb)

total capacity (Btuh)

hlwb = hewb –

4.5 x cfm

Where: hewb = Enthalpy of air entering indoor coil

3.SHC is based on 80 F edb temperature of air entering indoor coil. Below 80 F edb, subtract (corr factor x cfm) from SHC.

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