5E Analyses of the Cogeneration System Based on Mass Integration Driven by Low-Temperature Waste Heat

In the face of increasingly grave global concerns such as climate change, environmental risks, and energy restrictions, the progress of efficient energy use has emerged as a focal point of research on this subject. This study proposes a novel combined refrigeration and electricity generation system (NCREGs) based on mass integration and provides a thorough analysis of the system's characteristics, exergy, economics, environmental impact, etc. The results show that, in comparison to our team's previously published cogeneration system under ideal operating conditions, NCREGs' exergy destruction is reduced by 39.12%, and their exergy efficiency is increased by 2.01%. The economic study also showed that the payback period decreased from 2.47 to 1.22 years and that the total cost of NCREGs was reduced by 38.88%. The environmental analysis showed that NCREGs' total equivalent warming impact has been further reduced by 15.69%. Therefore, NCREGs tout higher economic viability and environmental friendliness in addition to the benefits of decreased energy consumption and increased energy efficiency. The mass integration cogeneration system presented in this study offers insights into the efficacious exploitation of low-temperature waste heat in industrial settings, consequently serving as a reference for the creation of more proficient energy systems.
