摘　　要：以高层住宅集中-分散太阳能热水系统的管路热损率为研究对象，通过理论计算及数值模拟方法对天津某-太阳能热水工程进行研究。结果表明，集中-分散太阳能热水系统管路热损较大且受影响因素较多，保持其他参数不变的情况下，管路热损率随保温层厚度的变化范围为10％-60％、随管径的变化范围为15％-25％、随建筑层数的变化范围为15％-25％、随敷设方式的变化范围为16％-40％，并分别给出了规律曲线，为今后此类太阳能热水工程设计中管路热损取值提供了参考。The pipeline heat loss rate of centralized-individual solar water supply system in high-rise residential building was studied on a project in Tianjin by the method of theoretical calculation and numerical simulation. The results show that the pipeline heat loss of centralized-individual solar water supply system is large and susceptible to many factors. The variation of pipeline heat loss rate with insulation thickness is 10%-60%,with pipe diameter is 15%-25%, with total number of building floors is 15%-25%, when other parameters are unchanged. All the variation curves were given in the paper which can provide a preference for the future engineering design.
