Abstract

This paper deals with the development of performance of domestic vapour compression refrigeration system using the hydrocarbon refrigerant R600a and R290, hydrocarbon refrigerant (R600a and R290) with SiC nano powder and hydrocarbon refrigerant (R600a and R290) with cryogenically treated SiC nano powder. Generally, hydrocarbon refrigerant is used as working fluid in domestic refrigeration. The Coefficient of performance, freezing capacity is increased by dispersing the SiC nanopowder in hydrocarbon refrigerant. Moreover, the cryogenic treatment was also done on SiC nano powder to improve the performance of the system. Cryogenic treatment is a cold treatment done on SiC nano powder at -196° C for 24 hours. Due to this treatment, the further improvement on COP and freezing capacity were observed. The power consumption of refrigeration system was also reduced when compared with conventional refrigeration system. In this work the performance of the refrigerator using nano refrigerant is to be analysed.
