BF — Bypass Factor

CFM — Cubic Ft per Minute

EWB — Entering Wet Bulb ( °F)

SHG — Gross Sensible Capacity 1000 Btuh

TCG — Gross Cooling Capacity 1000 Btuh

NOTES:

1.Contact manufacturer for cooling capacities at conditions other than shown in table.

2.Formulas:

3.Direct interpolation is permissible. Do not extrapolate.

4.SHC is based on 80°F db temperature of air entering coil. Below 80°F db, subtract (Correction Factor x CFM)

from SHC. Above 80°F db, add (Correction Factor x CFM) to SHC

5.All data points are based on 10°F superheat leaving coil.

Leaving wb = wb corresponding to enthalpy of air leaving coil (hlwb)

total capacity (Btuh)

hlwb = hewb —

4.5 x CFM

where hewb = enthalpy of air entering coil.

Interpolation is permissible.

Correction Factor = 1.09 x (1 – BF) x (db – 80)
