Abstract
The use of nanoparticles along with the normal lubricating oil in vapour compression cycle is a relatively a new idea. By using nano particles in lubricating oil we can improve the thermal and physical properties of the conventional lubricating oil, thus improve the overall performance of Vapour Compression Refrigeration System. In this study heat transfer enhancement was investigated experimentally by using alumina (Al2O3) nanoparticles of size 40-50 nm diameter with lubricant (PAG oil) and the refrigerant (R134a). Stable nanolubricant has been prepared with the help of magnetic stirrer followed by sonication. The experimental studies indicate that the refrigeration system with nanolubricant works normally. It is found that the freezing capacity is improved and increases by 86.26% for .3% of Al2O3 (% wt.) nanoparticles and the COP increases by 31% in comparison to normal lubricating oil. Thus using Aluminium oxide nanolubricant in refrigeration system is feasible.
