BF— Bypass Factor edb— Entering Dry-Bulb Ewb— Entering Wet-Bulb kW — Total Unit Power Input ldb— Leaving Dry-Bulb lwb— Leaving Wet-Bulb

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

*At 75°F (23.8°C) entering dry bulb (Tennessee Valley Authority [TVA] rating conditions); all other at 80°F (26.6°C) entering dry bulb.

COOLING NOTES:

1.Ratings are net; they account for the effects of the evaporator fan motor power and heat.

2.Direct interpolation is permissible. Do not extrapolate.

3.The following formulas may be used:

Example: 15.0 kW (at 240v) heater on 208v

=15.0 (.75 mult factor)

=11.25 capacity at 208v

Sensible capacity (Btuh) tldb = tedb --1.10 x cfm

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

total capacity (Btuh) hlwb = hewb ---

4.5 x cfm

Where: hewb = Enthalpy of air entering evaporator coil

4.The SHC is based on 80_F (26.6_C) edb temperature of air entering evaporator coil. Below 80_F (26.6_C) edb, subtract (corr factor x cfm) from SHC.

Above 80_F (26.6_C) edb, add (corr factor x cfm) to SHC. Correction Factor = 1.10 x (1 + BF) x (edb + 80).

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