The Glasgow Agreement of COP26, aimed at addresing climate change and preventing a temperature rise of 1.5℃ introduced regulatory measures to control the use of high Global Warming Potential (GWP) HFC refrigerants as part of greenhouse gas regulations. In addition to the Glasgow agreement, the European Union (EU) has implemented F- Gas regulation, outlining annual scenarios for reducing HFC refrigerant usage and announcing limitations on the GWP of refrigerants used in refrigeration and cooling apliances annually. The conventional refrigerant traditionally
used in refrigerated showcases exhibits a notably high GWP, which makes in non-compliant with F-Gas regulations in European market. Consequently the adoption of refrigerants possessing lower GWP values has become imperative. R744, categorized as a natural refrigerant, is gaining prominence due to its inherent low GWP values has become impertuve. R744, cateforized as a natural refrigerant, is gaining prominence due to its inherent low GWP charactoristics. Researches are currently in progres to examine the thermodynamic cycles employed in cooling and refrigeration systems utilizing R744. In this study, modeling of the refrigeration cycle in showcases employing R744 as the refrigerant was conducted with an analysis of the resultant performance modifications, including to comparative assessment of cooling capacity and the Coefficient of Performance (COP).
