摘　　要：生活热水太阳能集热器的设计日用水量应取平均日用水量而不是最高日用水量,平均日用水量在缺少实测资料的前提下可按现行最高日用水量的50%选取。储热水箱中的终止设计温度是所允许的最高水温,按60℃选取为宜。太阳能保证率是设计日用热水负荷中太阳能加热提供的热水比率,一般为30%～80%,太阳能资源丰富地区取高值、贫乏地区取低值。The design daily water consumption of domestic hot water solar heat collector should take the average daily water consumption instead of the maximum daily water consumption. The average daily water consumption can take 50% of current maximal daily water consumption in the absence of measured data. The final design temperature of hot water storage tank is the permissible maximum water temperature and should take 60 ℃. The solar fraction is the ratio of solar energy supplied to heat water, and generally is 30% to 80%. The high value is taken in the region full of solar energy resources, and the low value is taken in the region poor of solar energy resources.
