摘要
室外气温与太阳辐射强度之间存在某种随动关系，以中国南方13个典型城市气象数据为依据，通过回归分析方法，得到了太阳辐射与地表温度的动态拟合关系及地气温差随时间变化的动态拟合关系，各拟合公式相关系数 R 2均在0．97以上，说明拟合结果能显著的反映数据点的变化规律，进而建立了室外气温与太阳辐射强度的随动性关系。结果表明：高原地区，太阳辐射是室外气温与时间的一次函数；平原地区，太阳辐射是室外气温与时间的对数函数。对建筑冷负荷计算提供简便的方法，同时，也为太阳辐射强度与建筑冷负荷的随动性关系及太阳能空调的适宜性研究提供科学依据。
Abstract
There is a dynamic relationship between outdoor air temperature and solar radiation.Based on the meteorological data of 13 typical cities in south China and by the regression analysis method,the dynamic fitting function between the solar radiation and the land surface temperature and the function of temperature difference between the air and land surface changing over time are established.And the correlation coefficient R2 are over 0.97 which indicates that the results can significantly reflect the variation of data points,then the dynamic relationship between outdoor air temperature and solar radiation is obtained.The results suggest that solar radiation is a linear function of the outdoor air temperature and time in the plateau,while logarithmic function of both in the plains.The study will provide convenient method for building cooling load calculation, and provide scientific basis for studying the dynamic relationship between the solar radiation and the building cooling load as well as the suitability of the solar energy air conditioning.
