中文摘要:

      为太阳能有机朗肯循环系统(Organic Rankine Cycle, ORC)合理选择工质需要综合考虑太阳能辐射强度和环境温度的影响。基于建筑热工设计分区和太阳能资源区划标准,将我国分为了11个太阳能利用区。利用太阳能ORC热力学能量流通数学模型,以太阳能ORC系统典型月平均热发电效率最高为原则,为太阳能ORC系统绘制出推荐的工质地图。

英文摘要:

      The selection of the organic energy of the Organic Rankine Cycle (ORC) requires consideration of the effects of solar radiation intensity and ambient temperature. Based on architectural thermal design zoning and solar resource zoning standards,China is divided into 11 solar energy use areas.Using the mathematical model of solar energy ORC thermodynamics energy flow, the recommended working fluid map for the solar ORC system is deduced with the principle of the maximum monthly average thermal power generation efficiency of the solar ORC system.
