摘　　要：在晴朗天气条件下,对一款组合平板集热器和真空管集热器的太阳能热水器进行了实验测试与分析,并与真空管太阳能热水器进行对比.结果显示,组合式太阳能热水器日得热量稍高,升温速度快,循环效率高,温度分层相比真空管热水器更明显;但组合式热水器平均热损因数稍大,夜间损失的能量较多.Under clear weather conditions,a solar water heater incorporating both flat plate and vacuum tube collectors was tested,analyzed,and compared with a conventional vacuum tube solar water heater.The results indicate that the hybrid solar water heater exhibits marginally higher daily heat gain,more rapid temperature rise during low-temperaturephases,superior cyclic efficiency,and more pronounced temperature stratification compared to vacuum tube water heaters.However,the combined system demonstrates a slightly higher average heat loss factor and greater energy loss at night.
