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:

sensible capacity (Btuh)

tldb = tedb –

1.10 x cfm

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

Where: hewb = Enthalpy of air entering evaporator 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..

Cap. — Heating Capacity (1000 Btuh) (includes indoor-fan motor heat) db — dry bulb

kW — Total Power Input (includes compressor motor power input, outdoor-fan motor input, and indoor-fan motor input)

NOTES:

1. indicates integrated ratings.

2.Integrated capacity is maximum (instantaneous) capacity less the effect of frost on the outdoor coil and the heat required to defrost it.
