4.2 Capacity Correction Based on Refrigerant Piping Length
< Cooling Capacity >
Correction factor for cooling capacity according to piping length. The correction factors are shown in
the following gure.
The cooling capacity should be corrected according to the
following formula:
Equivalent piping length for
CCA=CC×F
CCA: actual corrected cooling capacity
CC: cooling capacity in the performance table
F: correction factor based on the equivalent piping length
● one 90° elbow is 1.6ft. (0.5m).
● one 180° bend is 4.9ft. (1.5m).
● one branch pipe is 1.6ft. (0.5m).
