This article review of varied mass charges of Liquid Petroleum Gas (LPG) in place of R134a, with varied concentration of SiO2 nano lubricant and making the refrigerator better by using the varied length of the capillary tube. Thereby increasing of all types of properties of refrigerator enhanced with varied concentration of SiO2 nanoparticle with mineral oil in a R134a compressor of a domestic refrigerator. It is assumed that with the use of SiO2 nano particle refrigerant the perform of system like pull down time, power consumption through refrigerator is reduced, compressor power input, cooling capacity and coefficient of performance (COP). Analysis was based on temperature and pressure readings obtained from appropriate gauges attached to the test rig. In conclusion, LPG-SiO2 nanolubricant mixture works safely and efficiently in domestic refrigerators with modification of capillary tube length. Using this mixer can reduce the system's irreversible process.
