Özet

In this study, a new refrigerant HFE7000, has been investigated thermodynamically in the cascade cooling system. Energy (COP) and exergy efficiency of cascade cooling system with CO2/HFE7000 refrigerants are performed. In this regard, the impacts of various parameters on the COP and exergy efficiency and exergy destruction rate of CCS are studied. Moreover, the CO2 refrigerant is used in the low-temperature circuit and HFE7000 is used in the high-temperature circuit. The COP and exergy efficiency of cascade cooling system are found as 2.313 and 0.5482, for cooling application. In the last section, comparison with R134a refrigerant is done, which is widely used in cascade cooling system.
