Exergy assessment of a multistage multi-evaporator vapor compression refrigeration system using eighteen refrigerants

The use of lower global warming potential refrigerants as an alternative to hydrochlorofluorocarbons and hydrofluorocarbons from an environmental perspective is the need of an hour. The feasibility and possibility of alternative refrigerants in the existing refrigeration system can be recognized usi...
