4. Design of refrigerant tube
4-1 Refrigerant tube length and height difference
!
NOTICE
1. All manifolds must be the special manifolds provided by the manufacturer, or some serious failure may occur to the system!
2.
Indoor units shall be uniformly installed at both sides of the "U" shape manifold.

NOTICE
1.The converted length of the manifold is equivalent to 0.5m.
2.The indoor units should be installed equally on both sides of the U-shaped manifold.
3.When the outdoor unit is below and H is higher than 40m, the liquid pipe of the main pipeline needs to be increased by one size.
4.The allowable length of the first manifold assembly connected to the indoor unit should be equal to or less than 40m.But when all
the following conditions are met, the allowable length can be extended to 90m.
Conditions
1.
The diameter of all the main branch tube between t
manifold assembly
and the last
increased. (Please make the tube on site)
If the
diameter of
main branch is same as the main tube, then
no need to increase it.
2.When calculating the total extension length, The actual length
of
the above main branch tube
(Except for main tube and branch tube without increasing the
pipe diameter. )
3.The length between indoor unit and nearest
assembly is
is less than or equal to 20m.
4.The difference between [the length between outdoor and
furthest indoor] and [
the length between outdoor and nearest
indoor] is less than or equal to
5. All manifolds must use our special tube. Failure to operate in accordance with this requirement may lead to serious system failure!
