Standard Ratings
LEGEND
BF — Bypass Factor Edb — Entering
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:
|
| sensible capacity | |
tldb = tedb | – | (Btuh) | |
1.10 x cfm | |||
|
|
tlwb =
|
| total capacity | |
hlwb = hewb | – | (Btuh) | |
4.5 x cfm | |||
|
|
Where: hewb = Enthalpy of air entering evapo- rator coil
3.The SHC is based on 80 F edb temperature of air entering evaporator 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).
