摘要
解决新农村住宅冬季采暖问题是绿色节能建筑的一项技术壁垒。本文试验对比研究甘肃省民勤县两处相同朝向大小的新农村居住建筑室内空气温度和平均辐射温度,其中一处经外墙保温改造且利用太阳能主动采暖技术,另一处是未加任何改造的原始新农村住宅建筑。试验实时监测改造建筑的室内相对湿度、温度竖直分布和空气流速,并对室内温度与相关因素的关系进行分析。结果表明:在环境最低温度为-16.2℃的条件下,改造建筑的室内平均温度、平均辐射温度分别高出未改造建筑5.4℃和3.3℃,改造建筑室内湿度为58%,室内空气流速为0.28m/s;得到太阳能热水供暖时室内温度与暖气片热水温度和环境温度的二元线性关系。
Solving the problem of the new rural residential heating in winter is a technical barrier of green energy-saving building.This paper was studied the experimental comparison of two same toward the size of the new rural residential building indoor air temperature and mean radiant temperature in Minqin County of Gansu Province;one of the exterior wall insulation alteration and the use active solar heating technology,and the other was without any modification of the original new rural residential building.The temperature vertical distribution and air velocity in building was monitored constantly in the experiment,and the relationship between indoor temperature and related factors was analyzed.The experimental result indicated that under the condition of the lowest ambient temperature of-16.2℃,reconstructive of the building＇s indoor average temperature,the mean radiant temperature were higher than the unreformed of the construction of 5.4℃and 3.3℃,the reconstructive building indoor humidity of 58%,indoor air velocity was 0.28m/s,and obtained binary linear relations between the indoor temperature when the solar energy hot water heating and radiator hot water temperature and ambient temperature.
