In this study, hybrid graphene oxide (GO)-doped tin oxide (SnO2) nanoparticles were synthesized by a simple chemical precipitation method to produce a nanolubricant. A mass fraction of 0.75% hybrid nanoparticles in polyol ester (POE) was used in the preparation of the nanolubricant. In the synthesis of hybrid nanoparticles, GO nanoparticles were doped with SnO2 at mass fraction of 1%, 2% and 3%. Single and hybrid nanolubricants were used to determine the performance values required for compressor operation. According to the results, when hybrid nanoparticles obtained by doping 2% doped GO nanoparticles were used, the power required for compressor operation decreased by 13.47% compared to pure POE. In addition, electromagnetic modeling of the single-phase auxiliary compressor motor was performed using finite element analysis software. For the hermetic reciprocating compressor, the electric current, power dissipation and magnetic field data were analyzed. © 2022, King Fahd University of Petroleum & Minerals.EnglishArticle10.1007/s13369-022-07116-6
