notes

Replaceable core suction filters are commonly installed after a compressor failure has occurred. The core is replaced after the foreign matter or acid has been removed from the system.

Additionally, suction filters should be installed in all field-assembled systems.

Hot Gas Muffler

The purpose of the hot gas muffler is to smooth out the pulsations associated with the refrigerant vapor being discharged from a reciprocating compressor, reducing noise and vibration.

The pressure of the refrigerant vapor leaving a reciprocating compressor fluctuates rapidly because of the manner in which it is compressed by the reciprocating pistons. The muffler contains a perforated tube inside a shell. The pressure peaks cause some of the refrigerant vapor to pass from the perforated tube into the muffler shell. This shell is divided into chambers that allow it to absorb these peaks. In essence, the muffler shaves off the peaks of these pulsations and fills in the valleys, reducing the pulsating characteristic in the discharge line.

When used, the hot gas muffler should be located in the discharge line, as close to the reciprocating compressor discharge as possible. This minimizes the sound emission from the unmuffled section of discharge line.
