Abstract The humidification-dehumidification desalination system is known as an appealing process for small and medium scales, and high-salinity water desalination. These systems consist of humidifier and dehumidifier as the main components, energy sources for heating and electrical energy generation, accessories used for the fluid transfer or efficiency improvement, and measurement/control devices. Different system designs are reported and categorized based on enhancement in productivity, energy consumption and effective parameters such as gained output ratio, specific electrical energy consumption and production cost. According to input energy types and used components, these systems react differently, and the performance parameters change. This literature reviews past/current status and future ideas about humidification-dehumidification systems to pave the way for the researchers to improve this technology. All technologies that improve the humidification-dehumidification system performance via using efficient constitutes, renewable energy, heat recovery via multi-effect and multi-stage processes, accelerating the humidification and dehumidification processes by pressure variation or using heat pump as well as exergy and cost analyses are clarified. It is concluded that despite improving humidification-dehumidification system as a promising process for decentralized small-scale freshwater production applications, it requires further development to improve the system performance based on gained output ratio and economy.

用于海水淡化的空气加湿-除湿工艺:综述

摘要 加湿-除湿海水淡化系统是中小规模、高盐度海水淡化的理想工艺。这些系统由加湿器和除湿器作为主要部件、加热和发电的能源、用于流体传输或提高效率的附件以及测量/控制装置组成。根据生产力、能耗和有效参数(如增益输出比、特定电能消耗和生产成本)的提高,报告和分类了不同的系统设计。根据输入的能量类型和使用的组件,这些系统的反应不同,性能参数也会发生变化。该文献回顾了加湿-除湿系统的过去/现状和未来想法,为研究人员改进这项技术铺平了道路。通过使用高效成分、可再生能源、通过多效多级过程进行热回收、通过压力变化或使用热泵加速加湿和除湿过程以及火用和成本分析来提高加湿-除湿系统性能的所有技术被澄清。结论是,尽管改进加湿-除湿系统作为分散式小规模淡水生产应用的有前途的过程,但需要进一步开发以提高基于增产率和经济性的系统性能。通过使用高效成分、可再生能源、通过多效多级过程进行热回收、通过压力变化或使用热泵加速加湿和除湿过程以及火用和成本分析来提高加湿-除湿系统性能的所有技术被澄清。结论是,尽管改进加湿-除湿系统作为分散式小规模淡水生产应用的有前途的过程,但需要进一步开发以提高基于增产率和经济性的系统性能。通过使用高效成分、可再生能源、通过多效多级过程进行热回收、通过压力变化或使用热泵加速加湿和除湿过程以及火用和成本分析来提高加湿-除湿系统性能的所有技术被澄清。结论是,尽管改进加湿-除湿系统作为分散式小规模淡水生产应用的有前途的过程,但需要进一步开发以提高基于增产率和经济性的系统性能。澄清了通过压力变化或使用热泵加速加湿和除湿过程以及火用和成本分析。结论是,尽管改进加湿-除湿系统作为分散式小规模淡水生产应用的有前途的过程,但需要进一步开发以提高基于增产率和经济性的系统性能。澄清了通过压力变化或使用热泵加速加湿和除湿过程以及火用和成本分析。结论是,尽管改进加湿-除湿系统作为分散式小规模淡水生产应用的有前途的过程,但需要进一步开发以提高基于增产率和经济性的系统性能。
