Constructive design of suction headers
• Absolutely symmetrical structure (s. fig. below) - both in the header design and at the inlet of the suction gas line
and the pipe sections connected to the compressors
• Suction gas inlet:
– 2 compressors: centrally
– 3 and 4 compressors: via symmetrical "Y-joint"
A side entry is very disadvantageous (even at low gas velocity) due to uneven flow and oil distribution in the accu-
mulator. If there are compelling reasons for the side connection, the speed-controlled compressor should be con-
nected there.
• Pipe sections connected to the compressors:
– Exit upwards, 30° bevelled
– Intake openings in parallel to the header axis
– Pipe layout symmetrical to the compressors and with identical diameter
NOTICE
!
!
Prevent dirt intake!
The pipes should have a uniform distance to the header base, for example by means of a spacer (flat iron),
which is removed again after soldering or welding the pipes. As a general rule, all soldering or welding work
should be performed under a protective charge, and chips or other deposits should be carefully removed.
