1. Pipe "A" diameter (between indoor and branch pipe) (depends on indoor pipe)
Indoor (x100W)
18~28
32~56
63~160
226-300
450-600
Note:
• If the distance between the unit and the nearest branch ≥ 15m, Pipe "A" should be enlarged:
(1) The capacity of indoor unites ≤ 5.6kW, the gas pipe change to Ø15.88, the liquid pipe change to Ø9.52.
(2) 5.6kW ˂ the capacity of indoor unites ˂ 16.8kW,the gas pipe change to Ø19.05, the liquid pipe change to Ø9.52.
(3) The capacity of indoor unites ≥ 16.8kw,the liquid pipe change to Ø12.7.
• The first sub-manifold distance from the longest indoor unit piping length ≥ 40 meters:
(1) The first sub-manifold to the nearest indoor unit main pipe (gas /liquid pipe) must increase a specification.
(2) The distance between the nearest indoor unit distance between the indoor unit ≤ 40 meters.
2. Pipe "B" diameter (between branch pipes)
