摘　　要：随着城市化进程的发展,高密高层住宅已经成为现阶段居住建筑主导。因此,建筑立面安装分体式太阳能热水系统已成为大势所趋,但此系统应用受到建筑布局与建筑间距的影响。在现有居住建筑常见组团方式及相关规划设计标准的基础上,选择上海市常见的高层住宅形式,利用日照分析软件建立模型,模拟分析全年建筑遮挡关系对建筑立面分体式太阳能热水系统的影响,以及建筑遮挡对低楼层安装的集热器全年集热量的衰减。建议在建筑规划阶段,进行日照分析的基础上合理规划布局,改善住宅低楼层住户的太阳能热水系统的应用条件。With the development of urbanization process,high-density and high-rising buildings would be dominant in the modern cities.The separate solar heating water system installed on the building envelop would be one solution to increase solar thermal energy use,which will be influenced by the relative location between buildings.The existing common residential building models are made to simulate the shadow effect between buildings on the utilization potential of the separate solar heating water systems installed on the building envelops.The year-round reduced heating capacity of the solar collector installed for the lower floors is calculated.It is suggested that building integrated solar heating system will have higher efficiency.
