Assessing Sustainable Eco-Friendly Refrigerants: An EDAS Methodology Approach

Environmental concerns have made looking for eco-friendly refrigerants essential in recent years. Natural refrigerants including ammonium (R717), carbon dioxide (R744), & hydrocarbons (R290 and R600a) are some of the most promising alternatives. Compared to synthetic alternatives. Natural refrigerants are the best option for many cooling applications because of their excellent thermodynamic characteristics and energy efficiency. The usage of these environmentally friendly refrigerants will support sustainable refrigeration practises and help to lower greenhouse gas emissions. The search for environmentally friendly refrigerators has drawn a lot of attention recently as environmental concerns have increased. The investigation of alternate alternatives has been motivated by concerns over the negative impact of conventional chemical the refrigerants on the loss of ozone and global warming. Natural refrigerants, which provide a sustainable and environmentally benign alternative to cooling applications, are among the most promising choices. such as ammonia (R717), carbon monoxide (R744), and hydrocarbon (R290 and R600a), have emerged as the best options. for artificial substitutes. This introduction lays the groundwork for further investigation into the characteristics and advantages of these environmentally benign refrigerants. Investigating more suitable eco-friendly refrigerants is crucial for tackling the urgent environmental issues connected to conventional synthetic refrigerants. These refrigerants are problematic in the long run since they contribute to the destruction of the ozone barrier and the acceleration of global warming. Through the identification and promotion of natural refrigerants including ammonia (R717), oxygen (R744), and oils (R290 and R600a), the research seeks to create environmentally friendly alternatives. By using these green refrigerants in cooling systems, greenhouse gas emissions can be significantly reduced, which will help slow the effects of climate change. Additionally, by advancing environmentally conscious and energy-efficient refrigeration technology, our research promotes a more sustainable and greener future. A multi-objective optimisation strategy used to resolve choice issues is called EDAS, which It entails assessing prospective solutions according to how far they are from the Pareto front's average answer, which captures trade-offs between competing goals. By considering both the diversity of the solutions and their proximity to the mean, EDAS seeks to identify the most desirable options. The EDAS methodology assists decision-makers in finding the best solutions that balance various goals by combining these elements. In several disciplines, including engineering, finance, and environmental management, this strategy has been employed with success.
