Summary

The results of experimental and theoretical studies of the effect of Al2O3 nanoparticle additives on the viscosity, saturation vapor pressure, surface tension of R600a/mineral oil solutions are presented in the article. The model SP-QSPR - Skaling Principles -
Quantitative Structure-Property Relationship to describe the experimental data and predict nanofluid thermophysical properties at
wide range of parameters of state has been applied for the first time. It has been shown, that viscosity increase, saturation vapor pressure and surface tension decrease for refrigerant / oil solutions with additives of nanoparticles. These effects should be considered at assessment of nano-technology prospects in the refrigeration equipment.
