摘要
太阳能烟囱的应用可以加强太阳能自然资源的利用,削减不可再生能源的耗费。本文通过使用数值模拟的方法对太阳能烟囱房间的气流流动进行了模拟分析,特别研究了太阳辐射量、环境温度以及太阳能烟囱截面宽度对房间通风量的影响。数值模拟计算结果与理论计算结果吻合很好,为加强房间通风效果提供了理论依据。
The utilization of the solar energy could be promoted by the application of solar energy chimney, and meanwhile fossil energy consumption could be reduced. In this paper, the airflow of a room with a solar energy chimney was simulated and analyzed, influences of the solar radiation energy, the environment temperature and the width of the solar energy chimney section on the airflow rate of the room were studied. The simulation results were in good agreement with that of the theory. Base on the discussion, the theoretic principles to improve the room ventilation effertiveness could be provided.
