Friction losses of the ecological compressor: experimental investigations and analysis.

Author(s) : DAGILIS V., VAITKUS L.

Summary

Energy consumption of household appliances is strictly limited by EC regulations. This article presents results of experimental investigation of a household refrigerating compressor's friction losses. The main objective of the investigation was achieving higher compressors efficiency. In the paper, the authors try to summarize and present deeper analysis of the results obtained. The research revealed that for modern compressors, the oil viscosity has little influence on friction losses. The authors draw the conclusion that friction losses of such compressors are more determined by boundary lubrication than by hydrodynamic lubrication. With lower viscosity oils, part of boundary friction losses is increasing. The oils of refrigerating compressors hold large amounts of dissolved refrigerant. This increases the influence of cavitation on the load-carrying capacity of oil film. The problem is further complicated by increasing difference between compressor test conditions and compressor operating conditions in the refrigerator.
