1.1.3.4 Compare the total capacity from indoor side and outdoor side, select the main pipe
diameter according to the bigger one.
Main pipe L1 in the Fig.4-3, which upstream outdoor units total capacity is 10+12+16＝38, base on table.4-5,
the gas/liquid pipe diameter are Φ1-1/2(Φ38.1)/Φ7/8(Φ22.2), total capacity of the downstream indoor unit is
140×6+56×2+71×2＝1094, based on table.4-4, the gas/liquid pipe diameter are Φ1-1/2(Φ38.1)/Φ3/4(Φ19.1),
take the large one for your selection, final confirm the main pipe diameter is: gas/liquid pipe
Φ1-1/2(Φ38.1)/Φ7/8(Φ22.2).
