研究了一种在用于发电和海水淡化的太阳能烟囱系统的收集器下从海水中提取热量和水分的替代方法，目的是使用一维可压缩流动模型来估计用于海水淡化时的电力和淡水输出。研究发现，由于空气沿烟囱上升时释放出蒸汽潜热，组合工厂烟囱内气流的温度和速度低于经典工厂烟囱内的气流温度和速度。此外，联合电厂中空气涡轮发电机和水发电机的功率输出低于传统电厂。此外，基于中国大连淡水和电力价格的收入分析表明，拟建集热器半径为3000m的联合太阳能烟囱发电厂的烟囱高度低于445m比传统发电厂更经济。研究发现，临界烟囱高度取决于当地淡水和电力的价格。
An alternative method of heat and moisture extraction from seawater under the collector of a solar chimney system for power generation and seawater desalination is investigated with the aim of estimating the output of power and fresh water when used in seawater desalination using one-dimensional compressible flow model. It is found that the temperature and velocity of the airflow inside the chimney in the combined plant is less than that inside the chimney in the classic plant due to the release of vapor latent heat as the air rises up the chimney. Additionally, the power output from air turbine generators and water generators in the combined plant is less than that of the classic plant. Furthermore, a revenue analysis based on the price of fresh water and electric power in Dalian, China shows that the chimney less than 445m high for the proposed combined solar chimney power plant having a collector 3000m in radius is more economical than for the classic plant. The critical chimney height is found to depend on the local price of fresh water and electricity.
