For researchers working for decades to provide more effective heat transfer in many applications, nanofluid has emerged as one of the most intriguing subjects. A lot of researchers have lately looked into the novel idea of nanorefrigerant, which is a mixture of nanoparticles and refrigerant. Typically, the amount of electricity used varies by sector. In Malaysia, the residential sector is often one of the largest users of power. According to the literature, refrigerators and freezers in Malaysian homes account for 26.3% of total power use. For researchers who have been working for decades to achieve more effective heat transfer across a wide range of applications, the emergence of nanofluids has brought significant excitement and promise. Nanofluids, which are engineered colloidal suspensions of nanoparticles in conventional base fluids such as water, ethylene glycol, or oil, have demonstrated remarkable improvements in thermal conductivity and heat transfer performance compared to traditional fluids. This enhanced thermal behavior has spurred substantial research interest, as it holds the potential to revolutionize numerous industries where heat exchange plays a critical role, including electronics cooling, automotive thermal management, industrial processes, and renewable energy systems. Building upon this foundation, a growing number of researchers have recently turned their attention to the novel concept of nanorefrigerants. A nanorefrigerant is essentially a mixture of nanoparticles dispersed within a refrigerant, designed to enhance the thermophysical properties of the refrigerant itself. By incorporating nanoparticles such as metal oxides, carbon-based materials, or other advanced nanostructures, researchers aim to increase the thermal conductivity and overall efficiency of refrigerants used in cooling systems. This innovation is particularly significant because it could contribute to reducing the energy consumption of refrigeration and air-conditioning systems, which are major contributors to global electricity demand and greenhouse gas emissions.
