城市区域南北朝向室内表面温度特征

使用12月、4月、8月昆明城市区建筑物室内小气候的观测资料，分析了室内不同方位的墙体表面温度的特征、变化规律及差异。结果表明：南北朝向房屋不同内壁表面温度存在显著的时间和季节变化，4月和8月内壁表面温度较高，12月较低；12月室内表面温度变化受房屋朝向影响十分显著，4月和8月影响较小；南屋12月夜间S壁表面温度最大，昼间E壁最小；4月和8月则反之，夜间E壁表面温度最大，昼间S壁最小；北屋3个月份内夜间E壁表面温度均最大，昼间N壁最小。以上所得结果可为探讨房屋微气候特征和形成机制、原因，建筑物的合理设计和规划，以及改善人们居住环境的深入研究提供依据，并且为其它地区的相关研究提供参考。

Characteristics of Internal Wall Surface Temperature with South-North Orientations in Urban Area

The internal wall surface temperatures (Tws) in April, August and December in Kunming, a city located in low latitude plateau, were investigated. Results showed that internal Tws have different temporal and seasonal variations for different orientations houses. Internal Tws in April were of the highest, then August and December. Internal Tws differences among walls with different orientations were higher in December, and lower in April and August. For the south house, internal Tws is the highest on S-wall at night and is the lowest on E-wall in the daytime in December, but it is the highest on E-wall at night and is the lowest on S-wall in the daytime in April and August. For the north house, internal Tws is the highest on E-wall at night and is the lowest on N-wall in the daytime in December, April and August. The results can serve as a basis for further research on building microclimate and urban architecture designs. It gives also suggestions for similar studies in other area.
