摘要
通过对真空管太阳热水器的系列测试实验,对影响热水器热性能的几个因素进行了实验研究.得到了日效率ηd 与VAR正相关,与H 无明显关系,Ul 与VAR无明显关系的实验性结论.
Influentialfactors on the thermal performance of vacuum tube solar water heaters are re searched by the experimentes of vacuum tube solar water heaters.The experimentalresultsshow that daily efficiency ηdisdirectcorrelation with VAR,is notcorrelation clearly with H,heatloss coefficient Ulis notcorrelation clearly with VAR.
