        abstract = {In response to increasing environmental concerns regarding high-GWP refrigerants, this study presents a performance analysis of a vapour compression refrigeration system using mixtures of R600a (Isobutane) and R134a (1,1,1,2-Tetrafluoroethane). The experimental investigation evaluates blend ratios of 60:40, 70:30, and 80:20 (R600a: R134a by mass) to assess thermodynamic efficiency, particularly the Coefficient of Performance (COP), along with energy consumption and environmental impact. The findings reveal that the 80:20 mixture offers an optimal balance between efficiency, safety, and reduced global warming potential. Compared to pure R134a, the blend improves COP by up to 24%, while significantly lowering GWP. The study confirms that R600a/R134a mixtures are viable drop-in alternatives in existing domestic refrigeration systems, supporting the transition toward sustainable and eco-friendly cooling technologies in line with international environmental protocols.},
