CAPACITY CORRECTION
Cooling and heating capacity is lowered according to pipe length. Capacity can be obtained by referring to the capacity
curves below.
Corrected pipe length (m) = actual pipe length (m) + number of bends x 0.3 (m)
Corrected pipe length (ft) = actual pipe length (ft) + number of bends x 1 (ft)
