摘　　要：针对太阳能烟囱综合系统内强化海水蒸发这一关键环节,搭建了太阳能烟囱强化海水蒸发的小型实验装置.通过接触式测温元件,考察了系统内气流温升和湿含量变化,研究了改变系统结构条件时系统性能的变化.结果表明,烟囱入口处气流接近饱和状态,蓄热水体基本可以维持系统昼夜工作;提高水体的吸收率和优化烟囱的结构参数,可使系统的性能得到提升.A mini-type experimental apparatus was esablished, aiming at the key step to enhance seawater evaporation in integrated solar chimney system. The temperature and humidity of airflow were measured by thermal resistance, and changes of system performance at different structure conditions were studied. Results show that the airflow at the entrance of the chimney almost reaches saturation and the seawater can keep the system working during day and night. Increasing the water absorptivity and optimzing the structural parameters of the chimney can improve system performance.
