BF — Bypass Factor
edb — Entering Dry-Bulb
Ewb — Entering Wet-Bulb
kW — Total Unit Power Input
ldb — Leaving Dry-Bulb
lwb — Leaving Wet-Bulb
SHC — Sensible Heat Capacity, 1000 Btuh
TC — Total Cooling Capacity, 1000 Btuh (net)
NOTES:
1. Ratings are net; they account for the effects of the indoor-fan motor
power and heat.
2. Direct interpolation is permissible. Do not extrapolate.
3. The following formulas may be used:
sensible capacity (Btuh)
t=t –
ldb edb
1.10 x cfm
t = Wet-bulb temperature corresponding to enthalpy of air
lwb
leaving indoor coil (h )
lwb
total capacity (Btuh)
h=h –
lwb ewb
4.5 x cfm
Where: h = Enthalpy of air entering indoor coil
ewb
4. 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.
Correction Factor = 1.10 x (1 – BF) x (edb – 80).
