Isothermal membrane-based air dehumidification (IMAD), a recent emerged air dehumidification technology, separates the moisture from the humid air by using a selective membrane, through which only vapor molecules can transfer from the one side of the membrane at a high concentration to the other side at a low concentration. The IMAD process has superior performance potentially in energy and economic than other traditional dehumidification technologies. This paper comprehensively reviews the literature on IMAD including membrane characteristics, membrane configuration, membrane-related mass transport mechanism, and system design and operation, as well as the mass transfer modeling. State of the art in the IMAD is presented and finally the recommendations of future research are provided.

基于等温膜的空气除湿（IMAD）是一种新兴的空气除湿技术，它通过使用选择性膜将湿气中的水分分离出来，通过该膜，只有蒸汽分子才能以高浓度从膜的一侧转移到空气中。另一面浓度低。与其他传统的除湿技术相比，IMAD工艺在能源和经济方面具有优越的性能。本文全面综述了有关IMAD的文献，包括膜的特性，膜的结构，与膜有关的传质机理，系统的设计和操作以及传质模型。介绍了IMAD的最新技术，最后提供了未来研究的建议。
