4.2.4.2 Layout Principles
The layout principles are as follows:
●
If the outdoor unit is placed higher than the indoor unit, the maximum height
deviation between them should be less than or equal to 20 m. Install an oil
trap every 6 m to 7.5 m along the gas pipe in the vertical direction to ensure
system reliability.
●
If the indoor unit is placed higher than the outdoor unit, the maximum height
deviation between them should be less than or equal to 5 m.
NO TICE
● The height deviation refers to the distance between the stop valve of the
indoor unit and that of the outdoor unit.
●
is a sign of a tilt, and indicates 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.
