4.2.6 Dimension of Pipe between Indoor Branch and IDU
Dimension of pipe between indoor branch and IDU should be consistent with the dimension of
indoor pipe.
Fig. 12
Rated capacity of IDU C(kW) Gas pipe (mm) Liquid pipe (mm)
C≤2.8 Φ9.52 Φ6.35
2.8<C ≤ 5.0 Φ12.7 Φ6.35
5.0<C ≤ 14.0 Φ15.9 Φ9.52
14.0<C ≤ 16.0 Φ19.05 Φ9.52
16.0<C ≤ 28.0 Φ22.2 Φ9.52
NOTE: If the distance between IDU and its nearest branch is over 10m, then the liquid pipe of
ID U (rated capacity ≤5.0kW) shall be enlarged.
