摘　　要：聚焦于上海地区太阳能热水系统的设计及动态性能分析。分别以90人、300人和900人为单元设计了分布式、小型集中式、集中式太阳能热水系统。并以设计的数据为基础,利用TRNSYS软件分别模拟了三类系统在不同气候条件下的动态性能研究。研究结果表明,分布式系统的太阳能保证率较高,水温也会更高。对于不同典型气候地区,例如北京、敦煌、西安、成都等,当地的太阳辐照强度直接影响了太阳能热水系统的太阳能保证率,辐照越强的地方,太阳能保证率也更高,甚至可以达到70%~80%。The design of solar hot water systems in the off-grid areas of Shanghai is focused on. They design distributed, small-scale centralized, and centralized systems for 90, 300, and 900 people, respectively, using TRNSYS software to design based on the data, simulation studies were conducted separately. The research results show that under the conditions of the same area, the solar fraction of the distributed system is higher and the water temperature will be higher. For typical climate areas, such as Beijing, Dunhuang, Xi’an, Chengdu, etc., it is found that the local solar radiation intensity directly affects the local solar energy guarantee rate. The stronger the irradiation, the higher the solar energy guarantee rate can even reach 70%~80%.
