Abstract: Dehumidification is a very important issue in daily life and production. The traditional dehumidification technologies，such as refrigeration，liquid desiccant，are widely used，but have many shortcomings. This paper reviews the recent development of some novel dehumidification technologies，including membrane dehumidification，heat pump dehumidification，heating，ventilating，air conditioning (HVAC) dehumidification，thermoelectric cooling and electrochemical dehumidification. Their operational principles，advantages and disadvantages，and equipment are introduced. Besides，their future development directions are presented.

摘要： 空气除湿在日常生活和生产中是一个很重要的课题。但是，传统的除湿技术例如冷冻除湿、液体除湿等，虽然已经被广泛应用，但是仍有一定的不足。针对这些不足，很多新型的除湿技术应运而生。本文综述了近年来发展起来的一些新型除湿技术，包括膜除湿、热泵除湿、HVAC除湿、热电冷凝除湿和电化学除湿等技术，介绍了它们的工作原理、优缺点以及装置等，并且指出了它们未来的发展方向。
