摘　　要：基于系统能量平衡为原理的Solar-Bus法,研究比较了多个中国居住建筑集中式太阳能生活热水(SDHW)工程系统的年动态热性能。工程评价指标结果显示,提升住宅SDHW系统热性能需要重视降低系统热损失,住宅集中集热-分散辅热(CCDAH)系统表现出比集中集热-集中辅热(CCCAH)系统更好的热性能。住宅系统热性能季节差异明显,冬季热性能较差。相较而言,学生宿舍SDHW系统具有较好的热性能,需要进一步研究。经济性分析表明,辅助能源影响系统经济性,学生宿舍SDHW系统经济性明显优于住宅。中国居住建筑SDHW系统的推广应用需要提升整体热性能以及探寻适宜的应用场景。Based on the evaluation method which is based on energy balance of system,this paper studied and compared the annual dynamic thermal performance of several centralized solar domestic hot water(SDHW)systems in residential buildings in China.The evaluation index results of these projects show that it is necessary to pay attention to reducing the heat loss of the system to improve the thermal performance of SDHW systems in dwellings.The centralized-collector/distributed–auxiliary-heating(CCDAH)systems show better thermal performance than centralized-collector/centralized-auxiliary-heating(CCCAH)systems.In general,the thermal performance of the system in dwelling varies significantly in seasons,and the thermal performance in winter is poor.Relatively speaking,the SDHW system of student dormitory has better thermal performance,which needs further research.The economic analysis shows that auxiliary energy affects system economy,and the student dormitory SDHW system is significantly more economical than the system in dwelling.The promotion and application of SDHW system in residential buildings in China needs to improve the overall thermal performance of the system and explore suitable application scenarios to improve the market competitiveness of SDHW in residential buildings.
