In today’s world, refrigeration plays an important role to satisfy human needs. People are doing several researches to enhance the performance of Refrigeration systems. Aiming to improve the characteristics of the old refrigerants by introducing nano particles in it, nano refrigerant is a process of combination of nano particle with the refrigerant for the sake of better refrigeration process. To study the thermal conductivity and viscosity at different volume concentration, this paper presents a review on mechanism for improvement in VCRS performance by using Nano refrigerants. We are using eco-friendly refrigerant that is R134a and nano particle Al2O3, comparing coefficient of performance (COP) of pure refrigerant and Nano refrigerant. In general, with the increment of nanoparticle concentration the viscosity is increased and instantaneous enhancement of thermo physical properties such as thermal conductivity is seen. The viscosity of Nano refrigerant has been influenced by the viscosity of the conventional refrigerant.
