CLIVET MSAN-XMi 140T User Manual

Main pipe (Please refer to Fig.4-5 and Fig.4-7)
In Fig.4-6, the main pipe L1, the outdoor unit capacity is
16kW, and check the Fig.4-7 to get the size of gas pipe/liquid
pipe is ĭ19.1/ĭ9.5, and aslo the total equivalent length of liquid
side and gas side pipes is >90m,then check the Fig.4-4 to get
the size of gas pipe/liquid pipe is ĭ22.2/ĭ9.5, and according to
the maximum value principle, it should apply the ĭ22.2/ĭ9.5.

Note: When the total equivalent piping length of liquid + gas side is 90m, it must increase the size of air side main pipe. Besides, according
to the distance of refrigerant pipe and the over matched state of inner unit, when the capacity is decreasing it still can increase the gas side
main pipe size.

Inner branch pipes are a~f, the size selection please refers to
Table4-6. Note: The max. length of the branch pipe should not
longer than 15m.
Indoor unit branch pipe
The main pipes of indoor unit and the indoor unit branch pipe
components
The downstream inner units of the main pipe L2 are N1, N2, and
its total capacity is 28×2=56, the size of pipe L2 isĭ15.9/ĭ9.5,
and the branch pipe B should be FQZHN-01D.
The downstream inner units of the main pipe L4 are N3, N4, and
its total capacity is 28×2=56, the size of pipe L4 isĭ15.9/ĭ9.5,
and the branch pipe D should be FQZHN-01D.
The downstream inner units of the main pipe L5 are N5, N6, and
its total capacity is 28+22=50, the size of pipe L5 isĭ15.9/ĭ9.5,
and the branch pipe E should be FQZHN-01D.
The indoor unit below to the main pipe L3 are N3N6, and its to-
tal capacity is 28×3+22=106, the size of pipe L3 isĭ15.9/ĭ9.5,
and he branch pipe C should be FQZHN-01D.
The indoor unit below to the main pipe A are N1N6, and its to-
tal capacity is 28×5+22=162, and the branch pipe should be
FQZHN-01D, and because the total piping length of liquid + air side
is 90m, check Table.4-4, and the first branch pipe should apply
FQZHN-02D, and according to the principle of maximum value, it
should apply FQZHN-02D.
