Cumulative exergy analysis of heat exchanger production and heat exchange processes

In this paper, on the basis of cumulative exergy consumption theory, the cumulative exergy contribution of equipment in processes is emphasized. In this way, the theory can not only analyze the process energy performance, but also optimize both the process parameters and the size of equipment at the same time. Heat exchangers are extensively used in process industries. In this paper, heat exchangers are treated as products. By investigating and calculating the energy consumption in the production process of heat exchangers, the cumulative exergy consumption of heat exchangers is obtained. Finally, based on the cumulative exergy of heat exchangers, heat exchange processes can be optimized to minimize the total cumulative exergy consumption.
