"Advanced Materials in Refrigeration Systems: An In-depth Analysis of Novel Additives and Their Influence on Heat Transfer Efficiency and Energy Consumption"

Abstract

Abstract: This study explores the cutting-edge domain of nano refrigerants, aiming to boost the cooling performance of the widely used refrigerant R-134a by integrating a precisely balanced blend of CuO and SiO2 nanoparticles. The primary motivation for this research is the imperative to transform refrigeration systems, making them more energy-efficient and environmentally sustainable. The research methodology involves systematically creating a nano refrigerant by dispersing varying concentrations of CuO and SiO2 nanoparticles in R-134a. Selected for their exceptional thermal conductivity and stability, these nanoparticles have the potential to significantly enhance the heat transfer properties of the refrigerant. Initial stages encompass rigorous assessments of thermal conductivity improvements compared to the base R-134a, laying the groundwork for practical evaluations in a heat exchanger setup. In heat exchanger experiments, crucial parameters such as heat transfer coefficient, pressure drop, and overall heat transfer rate are precisely measured, providing a comprehensive understanding of the nano refrigerant’s real-world performance. The objective is not only to enhance thermal conductivity but also to optimize the nano refrigerant for effective and efficient heat exchange, thereby elevating the cooling capacity of R-134a. Stability studies are integral, ensuring the long-term viability of the nano refrigerant. Scrutinizing compatibility with commonly used refrigeration system materials and monitoring potential degradation over extended periods are essential.
