“…Cheng et al [5] proposed applying the SIE to the regenerator of the absorption refrigeration air-conditioning system, and the regeneration thermal efficiency of the solution of LiBr can reach 40%. Wu et al [6,7] used the SIE in liquid desiccant regenerator. They developed surface alkali-activated carbonized pine and drilled inkjet-treated basswood with good regeneration performance.…”

A liquid desiccant cooling system (LDCS) is a promising energy-saving air-conditioning system with the advantages of being driven by low-grade heat and excellent humidity control ability. However, the problems of high energy consumption and low energy utilization efficiency of its regenerator limit its further development. To improve, a novel solar interfacial regeneration (SIR) method is proposed. The method can convert solar energy into heat and locate the heat at the evaporation interface so that the regenerator has high energy utilization efficiency. Experimental studies were carried out on different liquid desiccants. The results show that the thermal regeneration efficiency of this method is 2.6 to 2.9 times that of the conventional thermal regeneration method. LiBr solution has the best regeneration performance, but MgCl2 and CaCl2 are cheaper. Considering energy utilization efficiency and economic cost, the mixed desiccant may be a better choice. These advances could make SIR-based LDCS a potential contender for future air-conditioning systems.

“…Energy systems must simultaneously increase their energy efficiency while meeting the needs for a decrease in CO 2 emissions. The situation is especially serious for the building industry because building energy use might represent roughly 40% of total global energy use and nearly 30% of CO 2 emissions [1]. Heating, ventilation, and air conditioning (HVAC) systems account for a sizeable amount of the total energy consumed by buildings; examples include 40-60% in China, 40-50% in Singapore, and 59% in Canada [2].…”
