Nanorefrigerants are a unique type of nano fluids which are mixtures of nanoparticles and refrigerants and have a broad range of applications in diverse fields for instance refrigeration. In this paper thermal–physical properties of nanoparticles suspended in refrigerant and lubricating oils of refrigerating systems were reviewed. The effects of nanolubricants on boiling and two phase flow phenomenon are presented as well. This can be considered as one of the key parameters for enhanced performance for refrigeration and air conditioning systems. Because of its superior thermal performances, latest up to date literatures on this property have been summarized and presented in this paper as well. The results indicate that HFC134a and mineral oil with TiO2 nanoparticles work normally and safely in the refrigerator with better performance. The energy consumption of the HFC134a refrigerant using mineral oil and nanoparticles mixture as lubricant saved 26.1% energy with 0.1% TiO2 nanoparticles compared to the HFC134a and POE oil system.By this paper we done an experimental work on nano refrigerant. In this the nanoparticles is AL2O3 which was used in PAG oil for134 type VCR system. The experimental analysis has been done by DLS particle testing and cop performance with nano refrigerants.al2o3 works normally and safely in the test rig. The test rig gives better COP when it is tested with nano lubricants than pure lubricants the heat transfer rate increased by using nano particles AL2O3.The results are in favour of AL2O3 with 5% more effective than pure one AL2O3 is feasible as nanolubricant in test rig
