 Abstract

The increasing environmental concerns related to traditional refrigerants, particularly hydrofluorocarbons (HFCs), have spurred global efforts to identify and adopt eco-friendly alternatives. Traditional refrigerants, while effective in cooling applications, are major contributors to global warming due to their high Global Warming Potential (GWP) and Ozone Depletion Potential (ODP). This paper investigates various eco-friendly refrigerants, including natural refrigerants like ammonia (NH3), carbon dioxide (CO2), and hydrocarbons (e.g., propane and isobutane), as well as synthetic low-GWP alternatives like hydrofluoroolefins (HFOs). These alternatives are compared across several criteria, including efficiency, environmental impact, safety, cost, and regulatory compliance. The analysis highlights that while eco-friendly refrigerants offer significant environmental benefits, their adoption faces challenges such as infrastructure compatibility, safety concerns, and higher initial costs. However, ongoing research, technological advancements, and supportive policy frameworks are poised to overcome these barriers, making the widespread adoption of sustainable refrigerants a feasible and necessary step toward mitigating climate change and protecting the ozone layer. This paper concludes by emphasizing the need for continued innovation, international collaboration, and public awareness to accelerate the transition to eco-friendly refrigerants, thereby ensuring a more sustainable future for refrigeration and air conditioning technologies.
