In view of the common floor condensation problem in the transitional season and"rainy and humidity season",accord-ing to the characteristics of high humidity area in South China and the classification of active and passive dehumidification control methods,this paper summarized the research status of the existing dehumidification floor,and found that the current dehumidifi-cation floor mainly made of permeable bricks cannot fully meet the control of indoor condensation.Therefore,in the future,we should start from the direction of regulating indoor humidity,and make a deep research on the materi...
