Function and Operating Principle of Cycle Components

7-1. Function and Operating Principle of Compressor (Reciprocating
Compressor contains lubricant that is applied to the piston part that compresses refrigerant gas from low
pressure to high pressure and the motor part that operates the piston part. The lubricant lubricates and cools
the piston and motor parts.
Low pressure refrigerant is distributed inside the compressor and high pressure refrigerant is compressed by
the piston and transferred to the condenser through a separate pipe.
Caution
- Compressor is charged with nitrogen gas and covered with a rubber cap when it is delivered. This prevents
the oxidation and blocks moisture from penetrating into the compressor.
If you hear the sound of nitrogen gas coming out when you remove the cap to replace the compressor, the
compressor is in good condition.
If the nitrogen gas has leaked, it means that moisture has penetrated into the component. In this case, you
should not use the component.
- It is not rare for the compressor to have eccentricity in the motor shaft when external impact is applied to it.
