(1)-2-3 How to obtain the equivalent piping length
1 PUHY-(E)P200YJM
Equivalent length = (Actual piping length to the farthest indoor unit) + (0.35
×
number of bends in the piping) m
2 PUHY-(E)P250,300YJM
Equivalent length = (Actual piping length to the farthest indoor unit) + (0.42
×
number of bends in the piping) m
3 PUHY-P350YJM
Equivalent length = (Actual piping length to the farthest indoor unit) + (0.47
×
number of bends in the piping) m
4 PUHY-(E)P400,450,500,550,600,650Y(S)JM
Equivalent length = (Actual piping length to the farthest indoor unit) + (0.50
×
number of bends in the piping) m
5 PUHY-(E)P700,750,800YSJM
Equivalent length = (Actual piping length to the farthest indoor unit) + (0.70
×
number of bends in the piping) m
6 PUHY-(E)P850,900,950,1000,1050,1100,1150,1200,1250YSJM
Equivalent length = (Actual piping length to the farthest indoor unit) + (0.80
×
number of bends in the piping) m
