In modern days, refrigeration systems are important for industrial and domestic applications. Domestic refrigerators mostly work on vapour compression refrigeration cycle. Performance of any VCR suffers from its poor heat transfer properties of refrigerants to surroundings. Many methods are implemented to transfer heat from condenser. Such as forced convection, fins, number of condenser coils etc. But they increase the cost as well as power consumption by sacrificing the performance of VCR system. Hence the Nano fluids may be a promising solution to the existing problems to increase heat transfer rates in compressor. 0.5% V of Al2O3Nano particles are mixed with POE oil and used as lubricant in compressor (Hermitically shield and Oil cooled) and R600a as refrigerant in 220L capacity refrigerator. Also a diffuser is attached at condenser inlet to convert kinetic energy to pressure energy so as to increase work done without compression. Experiments are conducted to analyse the performance.
