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 capacity (Btuh) |
| |
| 1.10 x cfm | |||||
|
|
|
| |||
tlwb | = | |||||
| leaving evaporator coil (hlwb) | |||||
hlwb | = hewb | – |
| total capacity (Btuh) |
| |
| 4.5 x cfm | |||||
|
|
|
|
Where: hewb = Enthalpy of air entering evaporator coil.
3.The SHC is based on 80 F edb temperature of air entering evapo- rator coil.
Below 80 F edb, subtract (corr factor x cfm) from SHC. Above 80 F edb, add (corr factor x cfm) to SHC. Correction Factor = 1.10 x (1 – BF) x (edb – 80).
