PIPE CONNECTIONS BETWEEN INDOOR AND OUTDOOR UNIT
35
ENGLISH
Header Method
Example : 6 Indoor Units connected
Ⓐ
: Outdoor Unit
Ⓑ
: Header
Ⓒ
: Indoor Units
Ⓓ
: Sealed piping
L 150 m
H 50 m
40 m
• * : Assume equivalent piping length of Y branch to be 0.5 m, that of header to be 1 m,
calculation purpose
• Indoor Unit should be installed at lower position than the header.
WARNING
!
Pipe length after header branching (a~f)
It is recommended that difference in length of the pipes connected to the Indoor Units is
minimized. Performance difference between Indoor Units may occur.
Total pipe length = A+a+b+c+d+e+f
≤
300 m
L
Longest pipe length
Equivalent pipe length(*)
A+f
≤
80 m
A+f
≤
100 m
l
Longest pipe length after 1st branch
f
≤
40 m
H
Difference in height (Outdoor Unit
÷
Indoor Unit)
H
≤
30 m (20 m : Outdoor Unit is lower than Indoor Units)
h
Difference in height (Indoor Unit
÷
Indoor Unit)
h
≤
15 m
