The total length of each liquid piping is as follows:
ø12.7 total length: 40 (A)
ø9.52 total length: 10 (B) + 15 (C) + 10 (D) + 10 (a) + 5 (b) + 10 (e) = 60
ø6.35 total length: 10 (c) + 10 (d) = 20
Therefore, when the piping length from the outdoor unit to the farthest indoor unit is longer than 30.5 m (100 ft),
Amount of additional charge = (40 × 0.11) + (60 × 0.054) + (20 × 0.021) + 0 + 3.5
