4.1.2 Layout Principles (NetCol500-A110)
The layout principles are as follows:
●
If the outdoor unit is higher than the indoor unit: The vertical height
difference between the indoor and outdoor units should not exceed 30 m.
(When calculating the height difference, use the bottom of the compressor as
the reference for the indoor unit and the top of the condenser as the
reference for the outdoor unit.) An oil trap should be set every 5 m to 6 m
along the vertical gas pipe to ensure system reliability, and an inverted trap
should be set at the liquid pipe.
●
The inverted U-shaped trap must be at least 1 m higher than the bottom of
the outdoor unit.
●
If the outdoor unit is lower than the indoor unit: The vertical height difference
between the indoor and outdoor units should not exceed 8 m. (When
calculating the height difference, use the bottom of the compressor as the
reference for the indoor unit and the bottom of the condenser as the
reference for the outdoor unit.)
●
The equivalent length of the one-way pipe should be equal to or less than
100 m.
●
In the figure,
is a sign of a tilt, indicating that the scale of the pipe
tilting is at least 1:200. The pipe tilting direction should be consistent with the
hypotenuse of the right triangle.
●
Pipes through the wall or floor of the equipment room should be routed in
tubes, between which sealing measures (firestop putty recommended) are
taken.
