Abstract

Many researchers are heading towards innovations and experiments on different refrigerants, due to environmental effects and lower efficiency of conventional ones. Heat transfer capacity of the refrigerant decides the performance of the refrigeration system. To improve thermal conductivity and ultimately heat transfer rate lubricant (POE oil/Mineral oil) are enhanced with Nanoparticles. Mixing of Nano-fluid with base refrigerant improves overall COP of the system and decrease power consumption. This paper is an attempt to review past and on-going research work in Nano refrigerants. This work focuses on the experimental study of the performance on base refrigerant (R134a) with Nano-material. Many researchers observed the performance of Nano refrigerant in different proportion by varying Nanoparticles size and shape. The effect of usage of Nano-materials on the thermal conductivity and coefficient of performance (COP) of the refrigeration systems has been studied. The effect on the rate of heat transferred through system and working parameters of set up is observed.

Keywords: Nano-fluid, Nanoparticles, Nano refrigerants, Nano lubricants, COP, Al2O3, TiO2
