Keywords:Aluminum oxide nanoparticles, Nanorefrigerant, Thermal conductivity, The COP of the system, Energy consumption.
In this paper , study deals with the experimental investigations of the performance of a vapour compression refrigeration system based on (R134a + Al2O3) nanorefrigerant. The experimental setup is build up as per the national standards of India, and made to function under varying conditions. Throughout the research work, an effort is made for analysing the effect of that of the nanoparticles on the performance of that of the refrigeration system. R134a is used as the base refrigerant which is one of the refrigerants used commonly . Aluminium oxide (Al2O3) nanoparticles of size (60-70) nm were being employed in that of the refrigeration system. Two concentrations of the nanoparticles were used. Observations revealed that there was an improvement in that of the thermo-physical properties of refrierant and also in the performance of the refrigeration system by the addition of aluminium oxide nanoparticles into the refrigerant. The COP of the system was also seen to be improved during that of the investigations (1.17% – 8.40%).
