千米建筑室外气候分布及对建筑冷热负荷的影响研究
Outdoor climate distribution of thousand-meter buildings and its effect on building heating and cooling loads
摘要：
基于大连市的基本气象条件，采用中尺度气象预报模式WRF V3.4对空气温度、相对湿度、风速随高度的变化规律进行了模拟研究，结果表明：在1 000 m高度范围内，空气温湿度线性变化，高度每升高100 m，空气温度下降约0.6 ℃，相对湿度增加约2%。在500 m以下高度，风速随高度升高近似呈指数规律增长；500 m以上高度，风速变化不大；在1 000 m高度范围内，因风速变化导致的围护结构传热系数最大增加3.3%；当进行空调负荷计算时，风速的影响可以进行简单修正，甚至可以忽略风速对空调冷负荷的影响。
Abstract：
Based on the outdoor climate condition in Dalian, simulates the vibration of outdoor air temperature, relative humidity and wind speed with the height using the mesoscale weather research and forecasting model WRF V3.4. The results indicate that the outdoor air temperature and relative humidity varies linearly within the range of 0 to 1 000 meters, and the temperature decreases about 0.6 ℃ and the relative humidity increases about 2% with the height increasing 100 meters. The wind speed increases exponentially below 500 meters and varies little above 500 meters, the heat transfer coefficient of building envelope increases 3.3% at maximum within the range of 0 to 1 000 meters, and the influence of wind speed can be considered by simply verification or be ignored in calculating air conditioning load.
