Abstract

Introduction

Global refrigeration equipment usage contributes significantly to climate change. Research on improving refrigeration system efficiency has been conducted, while there is a worldwide debate on climate change. Patents have deployed nanoparticles in various refrigeration systems by mixing them with conventional refrigerants, demonstrating their exceptional thermal and heat-transfer properties.

Methods

This study assessed the comparative performance of refrigeration systems using nanoparticles of SiO with traditional R600a refrigerant. The result of using nanorefrigerants in the experimental settings of the refrigeration process, including temperature and pressure, as well as their capacity to transfer heat, was evaluated based on published research. Using pure R600a refrigerant as the base fluid, an experimental investigation was conducted to determine the characteristics of the refrigeration unit.

Results

The heat transfer of the refrigerant limit served as the foundation for the presentation of the refrigeration framework. Using R600a as a refrigerant, the data comparison revealed that nanorefrigerants perform better in terms of heat conductivity and heat transfer coefficients than base refrigerants. Furthermore, nanorefrigerant refrigeration systems demonstrated a much higher coefficient of performance (COP).

Conclusion

The goal of the test was to confirm that the refrigeration system using nanorefrigerants functions as expected. The results showed that mixing R600a refrigerant with silicon dioxide nanoparticles raised the freezing point and decreased force utilisation by 3%. As a result, refrigeration systems can use silicon dioxide nanoparticles.
