摘　　要：以上海地区一栋高校学生宿舍楼的太阳能热水系统的实测热水用量为依据,分析了其热负荷变化规律。采用一年内逐月求和的辅助热量为目标函数,通过编制程序计算了集热器的最佳倾角。计算表明,最佳倾角与集热器的面积或太阳能保证率有关。在规范规定的30%~80%范围内,若太阳能保证率取低端和高端值,最佳倾角为36°;若太阳能保证率取中端值,最佳倾角为40°~41°。Based on the measured hot water consumption of a solar hot water system in a college student dormitory building in Shanghai,the variation law of its thermal load was analyzed.The optimal inclina-tion angle of the collector was calculated through programming using the objective function of monthly summation of auxiliary heat within a year.The calculation shows that the optimal inclination angle is related to the area of the collector or the solar energy guarantee rate.Within the range of 30%to 80%specified in the specifications,if the solar energy guarantee rate is set at the low and high end values,the optimal inclination angle is 36°;if the solar energy guarantee rate is taken as the mid-range value,the optimal inclination angle is 40°~41°.
