湿热湿冷地区夏季房屋热稳定性测试分析

湿热湿冷地区夏季室外空气相对湿度大,太阳辐射强度偏低,现有建筑的房屋热稳定性状况缺少基础性研究数据。本文选取该地区典型的居住建筑,对其夏季太阳辐射、室内外空气相对湿度、室内外空气温度和壁面温度等进行了现场测试。分析表明在该气候特征下,所测试居住建筑在夏季典型周期内的室内空气平均温度波幅为4.3℃,幅度较大且受朝向、围护结构构造做法等因素影响明显。

Testing and Analysis on Building Thermal Stability in Hot-humid and Cold-humid Area in Summer

The outdoor air relative humidity in hot-humid and cold-humid area in summer is high,while the sun radiation intensity is low.For the existing buildings in this area,the basic research data of thermal stability is absent.In this paper,a typical residential building was selected as the research object,the sun radiation,indoor and outdoor air temperature and relative humidity,and surface temperature were measured.Testing analysis shown that for the typical residential building with typical climate characteristics in summer,the averaged indoor air temperature fluctuation was 4.3 ℃,thich was relatively large and was obviously affected by the factors of orientation and envelope construction,etc.
