Standard Ratings
LEGEND
BF — Bypass Factor Edb — Entering Dry Bulb Ewb — Entering Wet Bulb
kW — Compressor Motor Power Input
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 heat capacity (Btuh) | |
1.10 x cfm | ||
|
tlwb =
hlwb = hewb – | total capacity (Btuh) | |
4.5 x cfm | ||
|
Where hewb = Enthalpy of air entering indoor coil.
3.The SHC is based on 80 F edb temperature of air entering evap- orator coil.
Below 80 F db, subtract (corr factor x cfm) from SHC. Above 80 F db, add (corr factor x cfm) to SHC. Correction Factor = 1.10 x (1 – BF) x (db – 80).
