摘　　要：本文以北京市平谷区1栋太阳能辅助供暖示范居住建筑为对象,对其供暖能耗进行了近1年的监测研究,计算得出该建筑冬季室内空气平均温度可达17℃、供暖季太阳能集热器效率为37.7%、太阳能贡献率为30.7%;太阳能辅助供暖系统回收期相对较长,但环境效益显著,年CO2减排量为4～4.7 t。在此基础上,针对太阳能辅助供暖系统提出了改进建议。In this paper,a demonstration residential building with solar assisted heating system in Pinggu,Beijing was taken as the research object,and the energy consumption of heating system was monitored for almost one year.The calculation results indicated that the averaged indoor air temperature was 17 ℃,the efficiency of solar collector in heating season was 37.7%,the contribution of solar was 30.7%.Although the payback period of the solar assisted heating system was relatively longer,its carbondioxide emission reduction could reach 4~4.7 t/a.Finally,several improvement suggestions for this system were put forward.
