Abstract

An experimental investigation of a solid desiccant cooling system for a research laboratory on the Algerian coast has been carried out. The system utilized flat-plate solar collectors for regeneration and was evaluated through a combination of individual component characterization, system modeling (using TRNSYS), and experimental validation. The results obtained have been validated and show that the efficiency of the rotary heat exchanger reached 65 %, the evaporative humidifier efficiency reached 94 %, and the desiccant wheel achieved efficiencies of 73 % on the process side and 66 % on the regeneration side. This translates to a significant dehumidification effect, reducing absolute humidity in the treated air by 9 g/kg, for the supply air temperature effectively maintained at a comfortable 24 °C. The close agreement between the simulated and experimental COP values (1.13 and 1.08, respectively) validates the chosen approach and confirms the potential of this technology for energy-efficient building cooling in the hot and humid Mediterranean climate of northern Algeria.

阿尔及利亚北部安装的固体干燥剂冷却系统的实验研究与模拟

对阿尔及利亚海岸研究实验室的固体干燥剂冷却系统进行了实验研究。该系统利用平板太阳能集热器进行再生，并通过单个组件特征描述、系统建模（使用 TRNSYS）和实验验证相结合的方式进行评估。验证结果表明，回转式热交换器的效率达到 65%，蒸发式加湿器的效率达到 94%，干燥轮的处理效率达到 73%，再生效率达到 66%。这意味着除湿效果显著，在供气温度有效保持在舒适的 24 °C 时，处理后空气的绝对湿度降低了 9 克/千克。模拟 COP 值和实验 COP 值（分别为 1.13 和 1.08）之间的接近一致验证了所选择的方法，并证实了该技术在阿尔及利亚北部炎热潮湿的地中海气候条件下用于节能建筑制冷的潜力。
