Al-Qadisiyah Journal for Engineering Sciences, 2023 This research aims to find ways to use different mixtures instead of R134a refrigerants that are more efficient and better for the environment. The Kyoto Protocol states that hydrofluorocarbon refrigerants must be replaced due to their high Global Warming Potential values, contributing to environmental damage.
