| 将设计的一套太阳能供暖系统在节能改造后的农宅（试验建筑）中应用，并与燃煤采暖炉供暖的农宅（对比建筑）进行冬季运行测试对比。室内温度和内墙壁温度分析结果显示，在同样的晴、阴天气条件下，试验建筑的室内平均温度都在16.5℃以上，温度波动幅度在3.8℃以下，而对比建筑室内平均温度在14.6~15.4℃，温度波动幅度达到6.6℃以上；试验建筑的内墙壁平均温度为12.9℃，温度波动幅度在1.0℃左右，而对比建筑的内墙壁平均温度为8.5℃，温度波动幅度在5.0℃以上。室内空气PM2.5和CO2浓度测试结果显示，试验建筑二者均在标准限值范围内，而对比建筑二者都远超出标准限值。整个冬季能耗测试结果显示，试验建筑比对比建筑节省电能3 390 kW·h，减少CO2排放量79.4%。因此，北方寒冷地区的农宅采用太阳能供暖其舒适性和节能环保效益都较好。 |

| In this paper, a set of solar energy heating system is designed for the renovated energy-saving rural houses (test building), which is compared with the winter operation of the houses heated by coal heating furnace(comparison building). The temperatures of the outdoor and of interior wall show that: Under the same sunny and cloudy weather conditions, the average indoor temperature is above 16.5 ℃,with temperature fluctuation range below 3.8 ℃ for the test buildings, while the respective temperatures are respectively 14.6~15.4 ℃ and above 6.6 ℃ for the comparison building; The average temperature of the interior wall is 12.9 ℃,with fluctuation range about 1.0 ℃ for the test building, while the respective temperatures are respectively 8.5 ℃and above 5.0 ℃ for the comparison building. The concentration test of PM2.5 and CO2 for indoor air shows that the figures are within the standard limits in the test building, while they are far beyond the standard limits in the comparison building. Through the whole winter energy-consumption test, the results show that the test building has saved 3 390 kW·h electricity and lessened 79.4% of CO2 emissions compared with the comparison building. Therefore, it is better for rural houses in northern cold regions to apply the solar energy heating because of its advantages in comfort, energy saving and environmental protection. |
