<Heating Capacity >
Correction factor for cooling capacity according to piping length.
The heating capacity should be corrected according to the
following formula:
HCA=HC×F
HCA: actual corrected cooling capacity
HC: cooling capacity in the performance table
F: correction factor based on the equivalent piping length
