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 author’s previous theory and experimental study, the experimental verification of a computer program was used to evaluate the overall performance of a new loop heat pipe solar hot water system under actual climatic conditions. The study found that the operating temperature of the loop heat pipe is greatly affected by the solar radiation intensity; the system has a higher thermal efficiency in summer and a lower coefficient of performance. Compared with the traditional solar hot water system, the result shows that compared with the traditional system, the energy saving and emission reduction effect of the system is 0.040 tons of annual coal and 0.166 tons of CO2 emission reduction.
