4.1.1 Layout Principles (NetCol500-A060/NetCol500-A080/
NetCol500-A120)
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 inlet and outlet of the outdoor unit.
●
The inverted U-shaped trap should be higher than the top copper pipe of the
condenser.
●
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.)
●
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.
