摘要

摘要: 使用12月、4月、8月昆明城市区域内建筑物墙体内外壁表面温度的观测资料,分析了不同朝向墙体内外壁表面温度的特征、变化规律及差异。结果表明:4月和8月墙体内外壁表面温度较高,12月较低;不同朝向墙体之间的差异以天气晴朗的4月和12月较大,多云天8月最小;4月和8月E向墙体的内外壁表面温度均最大,S向次之,N向最小;而12月 S向墙体的内外壁表面温度在一段时段内甚至超过了E向;内壁表面温度的日较差低于外壁表面,且其出现最高、最低温度的时间均较外壁表面有所延滞。

Abstract: Internal and external wall surface temperatures (Tws) in April, August and December in Kunming, a city in low latitude plateau, were investigated. Results showed that the Tws in April were of the highest among the three, followed by August and December. The Tws differences among walls with different orientation were higher in April and December when the weather tends to be sunny, and lower in August with more cloudy days in the time. In April and August, Tws of E-wall was the highest, followed by S- and N-wall. But in December Tws of S-wall might be sometimes higher than E one. Diurnal range of internal Tws was usually smaller than that of the external, with also a time lag for the occurrence of its maximum and minimum. The results can serve as a basis for further research on building microclimate and urban architecture designs. It also gives suggestions for similar studies in other areas.
