摘要
在前期研究结果的基础上,进一步对太阳能烟囱海水综合系统中饱和湿热空气的间壁冷凝换热机理进行了探讨。以衰变因子模型为基础建立了冷凝水收集速率的非迭代模型,完善了基于扩散层理论计算冷凝水收集速率模型。结果表明两种模型较好地表达了实验系统中冷凝水收集情况和饱和湿热空气的冷凝换热情况,为综合系统的间壁冷凝换热提供了具体的实验和理论基础,为最大程度获得冷凝淡水找到途径。
The mechanism of indirect condensation heat transfer of saturated moist air in the combined system of seawater desalting and solar chimney was further studied based on the primary study. A non-iterative model for collecting rate of condensed water bsaed on attenuation coefficient model was buh, and another model bsaed on diffusion layer theory was improved. The results indicate that the models are suitable well for the water collection and the heat transfer of saturated hot air, provide specific experimental data and theoretical basis for the combined system, and seek the best way to obtaining the condensable freshwater to the largest extent.
