The main function of freezer oil

Reduce friction work, friction heat and wear;

Fill the sealing part with oil to ensure sealing performance and prevent leakage of refrigerant;

The movement of oil takes away the abrasive dust generated by metal friction, and plays the role of cleaning the friction surface;

Provide hydraulic power for unloading mechanism.

Performance requirements for freezer oils

Suitable viscosity: In addition to ensuring that the friction surface of the moving parts has good lubricity, the viscosity of the refrigerant oil also takes away part of the heat from the refrigerator and plays a sealing role. If the refrigerant used by the refrigerator has a large miscibility to the refrigerant oil, the use of oil with a larger viscosity should be considered to overcome the impact of the lubricating oil diluted by the refrigerant.

Small volatility, high flash point: the more volatile refrigerant oil, with the refrigerant circulation of the oil is more, so the refrigerant oil is required to narrow the range of the better, the flash point should also be higher than the refrigerator exhaust temperature of 25 ~ 30ºC.

Good chemical stability and thermal oxidation stability: the final compression temperature of the refrigerator can reach 130 ° C ~ 160 ° C, at this temperature, the refrigerating oil will be heated and constantly decompose and deteriorate, resulting in carbon accumulation, resulting in failure and wear of the refrigerator. Moreover, the decomposition products of the oil will chemically react with the refrigerant, making the refrigeration effect worse, and the acidic substances generated will strongly corrode the refrigerator components.
