摘　　要：为改善农村住宅冬季室内热环境,对青岛地区农村住宅进行了附加阳光间和节能火墙改造。通过对附加阳光间与节能火墙耦合供暖的房屋及相同结构的对比房室内温度及室外温度的监测,研究了寒冷季节室内温度随室外气象条件变化情况。结果表明:耦合供暖房屋室内平均空气温度比对比房室内平均空气温度高10.1℃,最高温差达13.2℃,最低温差5.4℃。通过对改造房屋节能率分析计算得出耦合供暖房屋节能率为72.8%,证明了该地区改造附加阳光间和节能火墙是可行且经济的。The attached sunspace and saving hot-wall was built in rural residences of Qingdao,which aims to improve the indoor thermal environment in winter.The variation regularity of indoor temperature with outdoor weather conditions was studied according to monitoring the data of experimental house,which was a coupled heating of attached sunspace and saving hot-wall combination and the contrast house with same structure,such as room temperature and outdoor temperature,etc.The results showed that the average air temperature in coupled heating house was higher than that in the contrast house by 10.1℃,and the maximum temperature difference reached 13.2℃,the lowest temperature difference was only 5.4℃.Through analysis of energy saving fraction,it was found that energy saving fraction of coupled heating house was high.It was feasible and economic to transform the attached sunspace and saving hot-wall in this area.
