Review: General Overview of the Research Conducted On Refrigeration with Added Nanoparticles CuO and Silica in Refrigerant R-134a

Abstract

The use of nanofluids, which are refrigerants enhanced with nanoparticles, has gained significant attention in the field of refrigeration systems. This study focuses on the addition of copper oxide (CuO) and silica nanoparticles in refrigerant R-134a to enhance heat transfer and improve system performance. The objective is to investigate the impact of these nanoparticles on the thermal and flow properties of the refrigerant and analyze their potential benefits in refrigeration applications. Experimental studies were conducted to evaluate the heat transfer performance and pressure drop characteristics of the nanofluid in a heat exchanger. The results indicate that the addition of CuO and silica nanoparticles can significantly enhance heat transfer rates, leading to improved cooling efficiency. However, careful consideration is required to optimize nanoparticle concentration and mitigate any adverse effects on system performance. The findings from this research contribute to the understanding of nanofluid-based refrigeration systems and offer insights for future development and application in the field of refrigeration.

The review initially highlights the motivation behind employing nanoparticles in refrigeration systems. The addition of nanoparticles to refrigerants has been reported to improve heat transfer characteristics, reduce compressor work, enhance energy efficiency, and mitigate environmental concerns associated with traditional refrigerants. With these advantages in mind, numerous studies have focused on investigating the effects of adding CuO and SiO2 nanoparticles to R-134a.
