不同结构的平板式阳台壁挂太阳能热水系统性能分析

Performance analysis of balcony hanging flat panel solar water heaters

针对竖直式和水平式两种流道结构的集热器进行对比试验,根据相关参数对两种热水系统的热性能进行了计算和对比分析,结果表明水平式流道的平板热水系统在瞬时效率、日平均效率、日有用得热量和升温性能4个方面均优于竖直式流道的平板太阳能热水系统。

We perform comparative tests for vertical and horizontal flow solar collectors. We further calculate and comparatively analyze the heat performance of these two water heaters. Results show that the horizontal flat panel solar water heater is superior to the vertical one in instantaneous efficiency, average daily efficiency, daily useful energy and warming performance.
