摘要
基于笔者前期理论及实验研究,运用实验验证的计算机程序,对一种新型环路热管太阳能热水系统在实际气候条件下的运行状况进行总体评估。研究发现,环路热管工作温度在很大程度上受太阳辐射强度影响;系统夏季热效率较高,性能系数较低。通过与传统太阳能热水系统进行比较分析,得出该系统相对于传统系统的节能减排效果为年节煤量0.040t、CO2减排量0.166t。
Based on the theoretical and experimental research conducted before, the operational performance of a novel loop heat pipe solar water heating system under the real weather conditions was analyzed by using a computational simulation program validated by experiments. It was found that the operating temperature of the loop heat pipe is greatly influenced by the solar radiation. The solar efficiency of the novel system is higher in summer, but with a low system COP （Coefficient of Performance）. By comparing with a conventional solar water heating system, the novel system had a total fossil fuel reduction of 0. 040t and carbon emission reduction of 0. 166t over the conventional one. Therefore, this novel system has significant meaning and positive propelling effects on the domestic and overseas targets of reducing energy usage and carbon emissions.
