A study on the use of dual mixed refrigerant in a cascade dual mixed refrigerant cycle [PDF]
In this article, a precooling cycle was used to reduce the power consumption and improve the heat transfer efficiency of a mixed refrigerant cycle. Propane precooling and mixed refrigerant precooling are two common precooling methods. The cascade dual mixed refrigerant cycle, which involves mixed refrigerant precooling and has a specific power ...

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.
