Brief introduction of dehumidification technology and research progress

Air humidity is one of the important factors that constitute the human body's thermal comfort. Inappropriate humidity will affect people's comfort and health. With the improvement of people's living standard, people have higher and higher requirements for indoor air quality, and air humidity is important factors that affect air quality. Thus it is an important task to control appropriate air humidity in air-conditioning engineering. This paper will briefly discuss and analyze the existing dehumidification technologies of air conditioning, compare the advantages and disadvantages of various dehumidification technologies, and look into the future research direction.
