4.0 Refrigerant Management System

The suction and interstage manifolds should be piped in

such a way that liquid cannot gravity drain into any compres-

sor. Carlyle recommends that the manifold be located below

the compressor body. An inverted trap must be used com-

ing off the top of the suction header if it is above the com-

pressor body.

NOTE: If suction or interstage piping is to be located above the compressor the recommendations in the figure below also

apply.

Mechanical subcooling via interstage manifolds are com-

monly applied with parallel 05T/06T rack designs. The gas

exiting the subcooler is used to provide additional motor

cooling in 06T models. This design reduces the amount of

liquid injection required for motor cooling. The manifold acts

Steel refrigerant piping is not recommended for use with

05T/06T screw compressor applications. The contaminants

associated with the steel pipe will overload the 3 micron fil-

ters used in the oil system increasing the chances of oil re-

lated compressor failures.

to efficiently distribute refrigerant gas to each compressor.

Interstage headers should be designed similar to suction

line manifolds.
