Liu, R.; Zhang, T.; Zhang, H., and Zhao, Q., 2020. Thermodynamic analysis of multistage flash seawater desalination system. In: Hu, C. and Cai, M. (eds.), Geo-informatics and Oceanography. Journal of Coastal Research, Special Issue No. 105, pp. 237–241. Coconut Creek (Florida), ISSN 0749-0208.

In this article, the structure of the seawater temperature difference energy multistage flash type seawater desalination system was studied, and the selection of the working medium, the thermodynamic analysis of the circulation system, and the exergy loss of the system were analyzed according to the system structure. The results showed that R134a refrigerants are more suitable to be used as working media in the system. According to the formula of the exergy loss of the circulating system and the flash evaporator, as the temperature of the surface seawater increases, the efficiency of the flash evaporator exergy loss will reduce. Through the analysis of the above-mentioned thermodynamics, a method for improving the energy utilization efficiency of the system can be found.
