Standard Ratings
LEGEND
BF — Bypass Factor
Edb — Entering Dry-Bulb
Ewb — Entering Wet-Bulb
kW — Compressor Motor Power Input
Ldb — Leaving Dry-Bulb
Lwb — Leaving Wet-Bulb
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 (Btuh)
t
ldb
=t
edb
−
1.10 x cfm
t
lwb
= Wet-bulb temperature corresponding to enthalpy of air leav-
ing evaporator coil (h
lwb
)
total capacity (Btuh)
h
lwb
=h
ewb
−
4.5 x cfm
Where: h
ewb
= 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).
