Desiccant coated heat exchanger (DCHE) has shown great potential for dehumidification in vapor compression cooling systems and has been widely concerned in the research field of air conditioning, as well as heat and mass transfer in recent years. This paper is aimed at providing fundamental knowledge and research progresses on DCHE for dehumidification and cooling. Initially, DCHE dehumidification is chosen as the research object in this review due to its superiority of the principle by comparing with other two typical dehumidification processes, which are condensation dehumidification and rotary-wheel dehumidification. Then, intermittent dehumidification and continuous dehumidification as two operation modes of DCHE are compared. Finally, the variation characteristics of temperature and humidity during operation are discussed. The current studies of DCHE are reviewed from four aspects, including desiccant coating, cooling source, regeneration heating source and basic heat exchanger. The performance analysis of DCHE is then conducted, according to the different effects of above aspects acting on dehumidification performance, cooling performance and energy efficiency of DCHE. The ongoing researches indicate that the rational construction of DCHE is an effective way to achieve its multi-objective performance optimization. The significant progress of DCHE lays the foundation for applications on other fields. However, further research is required in the field of the selection of desiccant coatings and the structure of heat exchangers to broaden its application market.

干燥剂涂层换热器（DCHE）在蒸汽压缩冷却系统中显示出巨大的除湿潜力，近年来在空调以及传热传质研究领域受到广泛关注。本文旨在提供DCHE用于除湿和冷却的基础知识和研究进展。通过与其他两种典型的除湿工艺——冷凝除湿和转轮除湿相比，DCHE除湿在原理上的优越性，因此本文首先选择DCHE除湿作为研究对象。然后，对DCHE的两种运行方式间歇除湿和连续除湿进行比较。最后讨论了运行过程中温湿度的变化特性。从干燥剂涂层、冷却源、再生热源和基本换热器四个方面对目前DCHE的研究进行综述。然后根据上述各方面对DCHE除湿性能、制冷性能和能效的不同影响，对DCHE进行性能分析。正在进行的研究表明，合理构建DCHE是实现其多目标性能优化的有效途径。DCHE 的重大进展为其他领域的应用奠定了基础。但在干燥剂涂层的选择和换热器的结构方面还需要进一步研究，以拓宽其应用市场。再生热源和基本换热器。然后根据上述各方面对DCHE除湿性能、制冷性能和能效的不同影响，对DCHE进行性能分析。正在进行的研究表明，合理构建DCHE是实现其多目标性能优化的有效途径。DCHE 的重大进展为其他领域的应用奠定了基础。但在干燥剂涂层的选择和换热器的结构方面还需要进一步研究，以拓宽其应用市场。再生热源和基本换热器。然后根据上述各方面对DCHE除湿性能、制冷性能和能效的不同影响，对DCHE进行性能分析。正在进行的研究表明，合理构建DCHE是实现其多目标性能优化的有效途径。DCHE 的重大进展为其他领域的应用奠定了基础。但在干燥剂涂层的选择和换热器的结构方面还需要进一步研究，以拓宽其应用市场。DCHE 的冷却性能和能效。正在进行的研究表明，合理构建DCHE是实现其多目标性能优化的有效途径。DCHE 的重大进展为其他领域的应用奠定了基础。但在干燥剂涂层的选择和换热器的结构方面还需要进一步研究，以拓宽其应用市场。DCHE 的冷却性能和能效。正在进行的研究表明，合理构建DCHE是实现其多目标性能优化的有效途径。DCHE 的重大进展为其他领域的应用奠定了基础。但在干燥剂涂层的选择和换热器的结构方面还需要进一步研究，以拓宽其应用市场。
