Capacities and Selection Data
<Heating Capacity >
Correction factor for cooling capacity according to piping length. The correction factors are shown in
the following gure.
The heating capacity should be corrected according to the following
formula:
Equivalent piping length for
HCA=HC×F
HCA: actual corrected cooling capacity
HC: 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).

H: vertical distance between indoor unit and outdoor unit
EL: equivalent total distance between indoor unit and outdoor unit
(equivalent one-way piping length)
H>0: position of outdoor unit higher than position of indoor unit
L: actual one-way piping length between indoor unit and outdoor unit.
