摘　　要：在建筑动态负荷模拟中,太阳辐射作为外扰中对建筑负荷影响最大的变量之一,其处理方法的正确与否直接影响了计算结果的精确性。通过对比不同软件在计算建筑各朝向立面的直射辐射时发现,在相同太阳辐射气象数据基础上,不同软件在模拟同一立面或平面的直射辐射强度时有较大差异且存在时间上的相位差。本研究获取了气象部门提供的专业实测太阳辐射逐分钟变化数据,在此基础上利用太阳直射辐射模型计算建筑各表面接收辐射的"真值",并改善建筑能耗模拟软件中直射辐射的模拟方法,在保证计算结果与"真值"的相符性基础上,尽量精简计算方法、提高计算速度。最后,为建筑能耗模拟软件提供一套由原始太阳辐射数据到建筑各表面接收太阳直射辐射的计算方法。In the dynamic simulation of building load,as one of the most influential variables in the external disturbances,the calculation of solar radiation affects the accuracy of the building load results.By comparing the results of several orientation direct solar radiations by different software,it found significant differences and phase differences on one plane or facade based on the different software. In this study,the solar radiation data is provided by meteorological department and is measured minute by minute. On the basis of the data,the ＂true value＂of the plane and orientation facades was calculated by direct solar radiation model. By comparing to the ＂true value ＂,the direct solar radiation model was improved. The improved model should be more simple and accurate. Finally,this paper provides a set of calculation method for building energy consumption simulation software to receive direct solar radiation from the original solar radiation data.
