ENHANCEMENT OF THERMOPHYSICAL PROPERTIES OF NANO REFRIGERANT

In modern days, refrigeration systems have become our daily usage in many applications. These systems consume more electricity as compared to other appliances and also releases harmful chlorofluoro carbons which causes global warming. A new emerging heat transfer fluid called nanofluid has been introduced in many applications. In recent years, refrigerant-based nanofluids and nano refrigerants have been introduced as significant effects of nanoparticles in heat transfer performance and energy consumption reduction. Many types of materials could be used as the nanoparticles to be suspended into the conventional refrigerants. In this study, the effect of the suspended copper oxide (CuO) nanoparticles into the R-600a which has Zero ODP and 3 GWP is investigated by using mathematical modelling. The investigation includes the thermal conductivity, dynamic viscosity, and heat transfer rate of the nano refrigerant in a tube of evaporator. The results show enhanced thermophysical properties of nano refrigerant compared to the conventional refrigerant. These advanced thermophysical properties increased the heat transfer rate in the tube which is helpful for reduction in energy consumption..
