R134a, also known as 1,1,1,2-tetrafluoroethane, has found extensive use in both domestic and commercial vapor compression refrigeration systems. The focus of present article is to explore potential replacements for R134a within vapor compression refrigeration systems. The replacement strategy involves an in-depth analysis of an ice plant that currently utilizes R134a as its refrigerant. As an alternative to R134a, a carefully proportioned mixture in a mass ratio of 0.1:0.4:0.5 for C1 and 0.1:0.5:0.4 for C2 after trial experiments were prepared with three refrigerants R32, R152a, and R245a to test for variations in density, enthalpy, entropy, global warming potential (GWP) and ozone depletion potential (ODP). Notably, the mixtures C1 and C2 were found to have GWP of 902 and 791 while a zero ODP value respectively as compared to GWP and ODP of 1296 and zero respectively of R134a. The mixture C2 has shown a significant reduction in density while enthalpy was seen increased for mixture C2 as compared to R134a. Coefficient of performance (COP) of C2 is increased by around 11% to 6.54 as compared to COP of R134a. The proportioned mixtures have been prepared to test the impact of different refrigerants on environment by measuring the parameters GWP and ODP. It is always an essential criterion to check the impact of refrigerants on environment before implementing it into the product. Moreover, the technical parameters like density, enthalpy, entropy and COP measurements are performed to analyze the advantages of prepared mixtures over the existing refrigerant. Due to comparatively lower GWP, higher COP and better heat extraction, C2 is recommended as the preferred replacement choice between the two options, C1 and C2.
