An experimental and theoretical investigation of the compressor oil and nanoparticles admixtures influence on the performance of the compressor systems.

The results of complex experimental and theoretical investigation of oil and nanoparticles of TiO2 and AlO3 admixtures influence on the thermo-physical properties of the refrigerant R600a, on the efficiency of a compressor system, and on the working fluid boiling intensity in a pipe are presented. It is shown, that the admixtures of the nanoparticles in the working fluid of the vapor compression refrigerating machine result in the increasing of the energy efficiency of the compressor system and positively influence the heat transfer coefficient during boiling of the working fluid in a pipe.
