Abstract

To further improve the regeneration performance of liquid-desiccant air conditioning systems, solar-driven interfacial evaporation was introduced in this work for solution regeneration. The effects of solution type and concentration on the regeneration rate and efficiency are studied. This new regeneration method is also compared with traditional thermal and membrane regeneration methods. The results show that, at 26 ℃, LiCl desiccant with 40% concentration achieved a regeneration rate of 0.39 kg/(m2·h), and KCOOH desiccant with 80% concentration achieved a regeneration rate of 0.37 kg/(m2·h). Compared to traditional membrane and packed-tower thermal regeneration method, this method demonstrated higher regeneration rates. Therefore, this new method has the potential to become a new efficient desiccant regeneration technique.
