  • Abstract

    Refrigeration and air-conditioning are essential for food preservation, medicine storage, industrial processing, and thermal comfort. However, conventional refrigeration systems rely heavily on synthetic refrigerants such as chlorofluorocarbons (CFCs), hydrochlorofluorocarbons (HCFCs), and hydrofluorocarbons (HFCs), which contribute to ozone depletion and global warming. With increasing environmental concerns and international regulations, there is a growing need for eco-friendly refrigerants with low global warming potential (GWP) and zero ozone depletion potential (ODP). This study focuses on optimizing refrigeration systems using environmentally friendly refrigerants such as carbon dioxide (CO₂), hydrocarbons (HCs), ammonia (NH₃), and hydrofluoroolefins (HFOs). System performance is evaluated through thermodynamic analysis, mathematical modeling, and computer-based optimization under various operating conditions. Key performance indicators include coefficient of performance (COP), exergy efficiency, cooling capacity, and total equivalent warming impact (TEWI). The results show that optimized systems using eco-friendly refrigerants can achieve performance comparable to or better than traditional systems while significantly reducing environmental impact. This research contributes to the development of sustainable refrigeration technologies aligned with global environmental goals.
