Recent progress in liquid desiccant dehumidification and air-conditioning: A review

This paper presents a literature review on the recent research progress in liquid desiccant dehumidification and air conditioning systems. The physical features of various liquid desiccant materials and their dehumidification performances have been summarized. With the aim to improve the dehumidification characteristics, mixed solvents desiccants have become research hot topics recently. Various types of dehumidifiers and their integration with liquid desiccant dehumidification system have been reviewed. The combination of liquid desiccant dehumidification system with solar collector, vapour compression system, heat pump system, CHP system, etc. have been grouped and compared. It is shown that the majority of the recent research work for liquid desiccant dehumidification systems has concentrated on numerical simulations, a considerable amount of works are still required for the practical investigations of innovative material (mixed solvents) and hybrid systems.
