Hollow fiber membrane-based dehumification technology is a new process which combines the liquid dehumification technology and membrane separation technology. It prevents the direct contact between the air and solution and thus solve the problem of liquid drop entrainment

which is harmful for human and metal. In this new process

the air and solution is separated. The heat and mass are coupled and exchanged through a selective permeable membrane. In this paper

the application possibility of this new technology in south China is investigated. The module and test condition are designed according to the features of fresh air in south China. A model is established for this model and it is validated via experiment. And the relation of module performance and inlet air flow rate

relative humidity

inlet solution flow rate and temperature are investigated. The heat and mass transfer mechanism in the module is discussed and performance optimization criteria is raised. The result provides basic theory for module design.
