| Abstract [eng] |
In this article the results of experimental investigation of household refrigerating compressor's friction losses are summarized and analysed. The main objective of the research was achieving higher compressors efficiency. The research revealed that for modem compressors the oils viscosity has low influence on friction losses. The authors draw 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 holds big amount of dissolved refrigerant. This increases the influence of cavitation on load-carrying capacity of oils film. The problem is further complicated by increasing difference between compressors test conditions and its operation conditions in refrigerator. |
