Research work has indicated that the performance of the refrigeration system with nano-refrigerant is normal as with that of any other conventional refrigerant. In the research work, the analysis of the performance of the refrigeration system is done with pure refrigerant R134a, pure R290, and blend of R134a+R290, as well as with the mixture of refrigerant R132a and R290 with CuO nano-particles called as nano refrigerants. COP of the nano-refrigerant mixture is increased as compare to the

... tional refrigerant. It is also observed that when the concentration of the nano-particles is increased i.e. (R134a+15%R290+0.100%CuO) beyond a certain level adverse effects are also observed like temperatures drop within the condenser was (110.38%) and also a gain of (110.54%) of drop in the evaporator temperature is observed. COP of the system is found to be increased by (133.95%) and power consumption was reduced by (11.52%) with the nano refrigerant as compared with pure refrigerant R134a.
