摘要
通过搭建PV/T一体化组件性能测试实验台,测试在不同进口水温、不同一体化组件倾角和不同流量时PV/T一体化组件的热、电效率。结果表明,在进口水温30℃工况下一体化组件拥有最优的热效率值和输出电功率值,其日总热效率为35.97%,对应的输出电功率范围为29.40~30.51 W;45°倾角放置的一体化组件可接收到较多的太阳辐照度,且具有最优的光热性能,对应的日总热效率为32.65%;流量85 L/h工况下一体化组件拥有最优的热效率值,对应的日总热效率值为25.89%,串联50Ω电阻时组件的输出电功率随流量的增大而增大,但变化较小,流量120 L/h工况下一体化组件拥有最优的输出电功率值,对应的输出电功率值范围为24.02~29.19 W。
