SHC Ð Sensible Heat Capacity, 1000 Btuh

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:

tldb = tedb ± sensible capacity (Btuh)

1.10x cfm

tlwb = Wet-bulb temperature corresponding to enthalpy of air leaving indoor coil (hlwb)

hlwb = hewb ± total capacity (Btuh) 4.5 x cfm

Where: hewb = Enthalpy of air entering indoor coil

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).
