|
摘要
对一种导流管式承压全玻璃真空管太阳能热水系统在晴天天气情况下的日得热量、平均日效率、系统平均热损因数、能效系数等热性能参数进行了热性能测试,并与传统式全玻璃真空管太阳能热水系统进行对比;分析了导流管式承压全玻璃真空管太阳能热水系统的实际运行特征及与传统式全玻璃真空管太阳能热水系统的区别.实验结果表明:导流管式承压全玻璃真空管太阳能热水系统相比传统的全玻璃真空管太阳能热水系统具有热性能良好,得热量高,平均热损因数小,太阳能热转换率更高等优势.
In this paper,an experimental study has been carried out to examine the operating characteristic of a heat-conducting tubular all-glass vacuum tube,under typical sunny weather condition,and experiments and calculations have been carried out to obtain the daily heat,daily average thermal efficiency,heat loss coefficient of the heater,the coefficient of energy efficiency,etc.which is also compared to that of a regular solar water heater.The investigation was carried out with a focus on the diversion of actual operating characteristics between a heat-conducting tubular all-glass vacuum tube and a regular solar water heater.It is shown that the thermal performance of such a solar heater is superior.The insulation performance of the the average heat loss factor is small,nevertheless,the result also demonstrate that the advantages of the solar thermal conversion rate is higher.
