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:

tldb = tedb – sensible capacity (Btuh)

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

total capacity (Btuh)

hlwb = hewb –

4.5 x cfm

Where: hewb = Enthalpy of air entering evap- orator coil

3.The 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.
