*At 75 F entering dry bulb (Tennessee Valley Authority [TVA] rating conditions); all others at 80 F entering dry bulb.
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 edb = Wet-bulb temperature corresponding to enthalpy of air leaving indoor coil (h lwb )
total capacity (Btuh)
h lwb = h ewb −
4.5 x cfm
Where: h ewb = Enthalpy of air entering indoor 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.
Correction Factor = 1.10 x (1 − BF) x (edb − 80).
