液体干燥剂技术是传统用于温度和湿度控制的技术的节能替代品；然而，创新干燥剂解决方案的性能和可行性尚未得到广泛探索。这项工作旨在从技术上和经济上研究通过吸湿分析的干燥剂解决方案。在气候室中测试了各种温度和湿度条件，并通过实验评估了传统和创新干燥剂解决方案的吸湿能力、热化学储能能力以及成本。尽管吸湿能力较低，但氯化钙表现出最高的吸湿能力（在 50 °C 和 25% RH 的气候室中为 0.3113 gH2O/gsol）和最低的成本。离子液体具有较高的吸湿能力（在25°C和90％RH的气候室中高达0.429gH2O/gsol），并且可以用作添加剂（由于离子液体的添加，吸湿能力最大增加了84.1％），因此，它们是传统干燥剂溶液的有希望的替代品。随着在各种条件下实现更好性能的解决方案的确定，该研究将推进液体干燥剂技术。
Liquid desiccant technology is an energy-efficient substitute for technologies that are conventionally applied for temperature and humidity control; however, innovative desiccant solutions have not been extensively explored in terms of their performance and feasibility. This work aimed to investigate desiccant solutions with moisture sorption analysis technically and economically. Various conditions of temperature and humidity were tested in a climatic chamber and the moisture absorption and desorption capacity, thermo-chemical energy storage capacity, and cost of conventional and innovative desiccant solutions were assessed by experiment. Calcium chloride showed the highest moisture desorption capacity (0.3113 gH2O/gsol in the climatic chamber at 50 °C and 25% RH) and the lowest cost, despite its low moisture absorption capacity. Ionic liquids show high moisture absorption capacity (as high as 0.429 gH2O/gsol in the climatic chamber at 25 °C and 90% RH) and could be used as additives (in which a maximum increase of 84.1% was observed for moisture absorption capacity due to the addition of ionic liquids), and thus, they are promising substitutes for conventional desiccant solutions. As solutions for better performance under various conditions were identified, the study will advance liquid desiccant technology.
