摘　　要：北京属于夏热冬寒地区,太阳能和空气源热能资源丰富,但各自独立运行时可靠性稳定性不足,通过"太阳能集热,辅助热源非供暖季采用空气源热泵,供暖季采用燃气锅炉"的复合能源方式,可有效解决全年全天候制热需要。以北京某高校新建学生宿舍生活热水系统为例,从系统构成、技术参数、工作原理等方面进行设计探讨,与传统热水制备方式进行能耗和成本测算对比,分析评价其节能和环保效益,结果表明系统运行稳定可靠,能量利用高效,节能减排显著,具有良好的社会经济效益,符合可持续发展要求,应大力推广。As a typical city in hot summer and cold winter regions,Beijing is rich in solar and air thermal energy,but neither can be used as a single heat source. This paper introduces the hybrid energy heating water system to meet the needs of all-weather heating throughout the year. The system uses solar energy combined with gas boiler in the heating season,and with air source heat pump in the other seasons.Taking a new student dormitory as an example,the system composition,main parameter and working principle are designed in the paper. Comparison is made with traditional methods in the aspects of energy-saving,operating cost and environmental benefit. The result indicates that the system possesses very notable socioeconomic performance and should be vigorously promoted.
