针对寒冷地区村镇附加阳光间典型住宅,在采暖期平均气温最低月份现场实测了典型住宅围护结构能耗情况,测试内容包括热环境、采暖耗热量、围护结构热工缺陷及传热系数,为进一步了解掌握村镇典型住宅能耗缺陷提供了实测数据。实测结果表明：住宅气密性较差,传热系数均不满足规范要求,外墙超标率高达165.23%,外墙、屋顶和外窗理论值与实测值相差分别为16.82%、3.04%、23.07%;采暖耗热量超标率为109.43%;附加阳光间比室外平均温度高7.47 ℃,但其温度不稳定,测试期间供暖卧室温度达到14 ℃的天数仅占47%。最后通过分析测试数据提出合理选择附加阳光间形式和围护结构节能措施等节能设计建议,推进附加阳光间在寒冷地区村镇住宅的应用。
Abstract
In the coldest month during the heating period, the energy consumption of the typical envelope enclosure of attached sunspace houses in villages and towns in cold regions was measured on-site. It helps to provide data for further understanding and mastering the energy consumption defects of typical houses. The test contents include thermal environment, heating consumption, thermal defects and heat transfer coefficient of envelope enclosure. The results show that the airtightness of the residence is poor, the heat transfer coefficient fails to meet the specified requirements, and the exterior wall exceeds the standard by 165.23%. The theoretical values of exterior walls, roofs and exterior windows is 16.82%, 3.04% and 23.07% higher than the measured values respectively. The energy consumption of heating exceeds the standard by 109.43%. The attached sunspace temperature is 7.47 ℃ higher than the outdoor average temperature, but its temperature is unstable. Only 47% of the days during the test, the temperature of the heated bedroom reached 14 ℃. On the basis of the analysis of the test data, this paper proposes energy-saving design suggestions such as how to choose the form of attached sunspace and the envelope enclosure reasonably, so as to promote the application of attached sunspace in villages and towns in cold regions.
