摘　　要：依据典型年气象数据,从建筑围护结构的朝向、季节、地理纬度和海拔高度等方面,对室外综合温度的时间和空间变化特性进行了分析.研究发现到达围护结构外表面太阳辐射强度是室外综合温度产生朝向差异的直接因素,季节变化影响室外空气温度进而影响室外综合温度的大小;随纬度降低,各朝向室外综合温度逐渐增大,随海拔高度的增加,太阳辐射强度对室外综合温度的影响高于室外空气温度.以室外综合温度、采暖室外计算温度计算建筑围护结构基本耗热量,发现采用前者比后者计算得到的基本耗热量小31.4%,采用室外综合温度计算所得结果更接近实际值.研究成果可为掌握室外综合温度时空变化特性以及建筑围护结构采暖热负荷的计算提供依据.Based on typical year meteorological data,the study analyzes the temporal and spatial variation characteristics of the outdoor integrated temperature from the orientation,season,geographic latitude and altitude of the building envelope.The results show that the solar radiation intensity reaching the outer surface of the envelope is a direct factor of the orientation difference of outdoor comprehensive temperature,and the changes of season affects the variations of the outdoor air temperature and then influence the outdoor comprehensive temperature.With the decreases of latitude,the outdoor comprehensive temperature increases gradually.With the increase of altitude,the influence of solar radiation intensity on outdoor comprehensive temperature is higher than that of outdoor air temperature.The basic heat consumption of building envelope is calculated by outdoor comprehensive temperature and outdoor heating temperature.It is found that the basic heat consumption calculated by the former is 31.4%lower than that calculated by the latter,and the results calculated by the outdoor comprehensive temperature is closer to the actual values.The researches can provide a basis for understanding the spatio-temporal variation of outdoor comprehensive temperature and calculating the heating heat load of building envelope.
