The influence of the compressor oil viscosity and fullerenes C60 additives in the oil on the energy

The analysis of the compressor oil viscosity and fullerenes C60 additives in the oil on the energy efficiency of refrigeration system with the household refrigeration compressor has been performed. The method of preparation of compressor oil with fullerenes C60 additives has been considered. The good aggregative stability of the fullerenes C60 in sample of nano-oil has been obtained.

Improving the efficiency of compression refrigeration equipment through the use of nanotechnology

Small impurity nanoparticles Al2O3 %, and TiO2 from % of circulating a working fluid along the contour compressor system significantly affects the coefficient of performance of the compressor system (15%) and the average heat transfer coefficient in boiling working fluid in the pipe (9%). Accounting for thermo-physical properties of the working fluid can adequately describe the processes of boiling nanoRHM in a pipe with an accuracy above 20%.
