Unit Capacity
Total cooling capacity can be detemined by using correc-
tion factors C1, C2 and C3.
Given cooling capacity = Cooling capacity at standard
rating conditions x C1 x C2 x C3.
C1 = Capacity correction factor for tempetature
C2 = Capacity correction for piping length
C3 = Capacity correction for indoor unit fan speed
Capacity correction factor for temperature
Capacity correction factor for indoor fan speed (C3)
