摘要:通過對寒冷地區典型鄉村居住建筑能耗狀況進行現場實測,分析其圍護結構熱工性能。利用紅外測溫技術檢測圍護結構是否存在熱工缺陷;采用熱流計法動態測試圍護結構的傳熱系數。結果表明:寒冷地區鄉村住宅門窗、屋面等部位存在熱工缺陷;墻體傳熱系數超標率高達162.92%;單位面積采暖耗熱量大;室內平均溫度達標率僅為27%。

Abstract:The thermal performance of enclosure structures is analyzed through field measurement of energy consumption of typical rural residential buildings in cold regions. Infrared thermometer technology is used to detect whether there are thermal defects of the enclosure structure. The heat transfer coefficient of the enclosure structure is dynamically measured by the heat flow meter method. The results show that there are thermal defects in the doors,windows and roofs of typical rural residential buildings in cold areas,the excess rate of heat transfer coefficient of the wall is as high as 162.92%,the heating consumption per unit area is large,and the qualified rate of average indoor temperature is only 27%.
