Thermodynamic performance assessment of a novel waste heat based triple effect refrigeration cycle.

Type of article: Article, IJR article
Summary
In the proposed triple effect refrigeration cycle, a natural refrigerant based N2O compression cycle is employed to the combined absorption cycle with an ejector refrigeration cycle. This triple effect cycle combines the advantages of absorption cycle, ejector cycle and low temperature N2O refrigerant based compression cycle. This combined cycle could produce refrigeration output of different magnitude at different temperature simultaneously and could be driven by the waste heat which is available abundantly in different form. System performance and exergy destruction on each component of combined cycle are evaluated based on parametric, energetic and exergetic analysis. The results show that the waste flue gas temperature, turbine inlet pressure, turbine outlet pressure, ejector evaporator temperature and compressor discharge pressure have significant effects on the refrigeration outputs, exergy efficiency and thermal efficiency.
