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 solar assisted heating demonstration residential building in Pinggu District of Beijing is taken as an object, and its heating energy consumption has been monitored for nearly a year. The calculation shows that the indoor average temperature of the building in winter can reach 17 ℃, The efficiency of the heater is 37.7% and the contribution of solar energy is 30.7%. The recovery period of the solar assisted heating system is relatively long, but the environmental benefits are remarkable. The annual emission of CO2 is 4 ~ 4.7t. On this basis, some suggestions for improvement of solar assisted heating system are put forward.
