Design of ionic liquids as a desiccant for the liquid desiccant type air conditioning system

Abstract Recently, liquid desiccant air conditioners (LDACs) have gained rapidly growing interest as an important candidate for an energy-efficient air conditioner. By enabling moisture absorption from the air, ionic liquids (ILs) can serve as a novel desiccant source for LDACs. For insights into the design and optimization of ILs to this end, we herein present a survey of studies on dehumidification and other relevant properties of ILs and offer some molecular perspective on their feasibility as a desiccant.
