The SHC is based on 80°F edb temperature of air entering evaporatorcoil. 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).5. Integrated capacity is maximum (instantaneous) capacity less the effectof frost on the outdoor coil and the heat required to defrost it.NOTES:1.
