This review paper presented on the energy analysis of the vapor compression refrigeration system using a mixture of R134a and LPG refrigerants with various concentrations of SiO2 nano lubricant with various capillary tube length in R134a compressor of a domestic refrigerator. In this paper the R134a (HFC) coolant high global warming capacity (GWP), immiscibility with issues of conventional mineral oil and flammability issue in Liquefied petroleum gas (LPG) (HC), and these problems can overcome by mixture of R134a and LPG coolant gives excellent results. It guess that the Nano particle refrigerant SiO2 is used in the mixture of R134a and LPG refrigerant can gives better properties and better results in domestic refrigerator .With the use of Nano refrigerant, the refrigerator parameters like compressor power can be reduced and compressor life can be increased. Coefficient of performance (COP) can be increased, second law efficiency and minimum IR-reversibility.LPG and SiO2 nano lubricant mixture work safely and efficiently in domestic refrigerator with and without modification of capillary tube length.
