Performance Evaluation of Nano-Lubricants at Refrigeration Oil

摘要：

It has been recognized that the friction coefficient decreased with decreasing viscosity of the lubricant oil in lubrication.In general,the more viscosity decreases,the more wear rate increases due to decrease of load carrying capacity.It has been proposed that nano particles in oil decrease the friction coefficient and wear rate.The purpose of this study is to apply oil of lower viscosity that mix with nano particles at the compressor used in a refrigerator to decrease friction coefficient keeping load carrying capacity.Mineral oil of 8 cSt was used and mixed with fullerene of 0.1 vol%.Friction coefficient was evaluated by a disk-on-disk tester.As a result,the friction coefficient of nano oil decreased by 90% in comparison with raw oil.These results lead us to the conclusion that nano oil is new plan to raise efficiency of the compressor.
