Research progress of humidification-dehumidification desalination process

Humidification-dehumidification(HDH) desalination process serves as an important supplement to traditional desalination processes.In this work,HDH systems are classified according to the use of latent heat,material circulation,form of driving,heat and mass transfer methods and energy supply.Components of the HDH systems,such as humidifier,dehumidifier and energy supply module,were analyzed in detail.Performance indices of the HDH systems were summarized.Finally,design suggestions for HDH systems were proposed in terms of material,desalination technology,structural design,etc.
