AI Technical Summary

Technical Problem

Existing scroll compressors suffer from reduced lubrication performance and severe wear due to compatibility issues between refrigerant and refrigeration oil in low-temperature and high-temperature heat pump applications. Furthermore, the centrifugal force generated by the cast iron moving scroll at high speed exacerbates vibration and noise.

Method used

The moving scroll disk is made of aluminum alloy and coated with a nano-graphene coating. Combined with a stationary scroll disk made of cast iron, the centrifugal force is reduced and the oil film stability is improved, avoiding adhesive wear. At the same time, the wear resistance of the nano-graphene coating is used to reduce frictional power consumption.

Benefits of technology

It effectively reduces wear and noise of the scroll compressor, improves lubrication performance and service life, and enhances system reliability and operating efficiency.
