热泵循环海水淡化系统分析

摘要

对三种主流的热法海水淡化方法进行评述,并对热泵循环海水淡化系统进行理论分析与计算,最后得出结论认为热泵循环海水淡化系统能耗没有显著降低,相比于低温多效蒸馏法无节能优势,系统能耗偏高的主要原因在于两种工质通过间壁换热,由于存在换热温差损失了大量可用能。%This paper introduced three kinds of mainstream in heat pump circulating seawater desalination methods,and made theoretical analysis and calculation to heat pump circulating seawater desalination system.Finally drew the conclusion that the energy consumption of heat pump circulating seawater desalination system did not significantly reduced,compared to the low temperature multi-effect distillation method without the advantage of energy saving.The main reason of system energy consumption high was because of the two kinds of refrigerant through the heat exchanger,due to the temperature difference lost a large amount of available energy.
