BF — Bypass Factor
Edb — Entering
Ewb — Entering
kW — Compressor Motor Power Input
Ldb — Leaving
Lwb — Leaving
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)
tlwb =
total capacity (Btuh)
hlwb = hewb –
4.5 x cfm
Where: hewb = Enthalpy of air entering evap- orator coil
3.The SHC is based on 80 F edb temperature of air entering indoor coil.
Below 80 F edb, subtract (corr factor x cfm) from SHC.
Above 80 F edb, add (corr factor x cfm) to SHC.
