1. Refrigeration oil, also known as refrigerating machine oil, is used to lubricate the moving parts in the refrigeration compressor.

(1) Lubrication:

The refrigerating oil plays a lubricating role in the operation of the compressor to reduce the friction and wear of the compressor, thereby prolonging the service life of the compressor.

(2) Sealing:

The refrigerating oil plays a sealing role in the compressor, so that the piston and the cylinder surface in the compressor can be sealed between the rotating bearings to prevent the leakage of the refrigerant.

(3) Cooling down:

When the refrigerating oil is lubricated between the moving parts of the compressor, it can take away the heat generated during the working process and keep the moving parts at a lower temperature, thereby improving the efficiency and reliability of the compressor.

(4) Energy regulation:

For refrigeration compressors with an energy adjustment mechanism, the oil pressure of the refrigerating oil can be used as the power of the energy adjustment mechanism.
