气象参数是建筑能耗模拟的基础,而逐时太阳辐射是建筑能耗模拟中最为重要的气象参数之一。介绍并比较了国内外逐时太阳总辐射模型和直散分离模型,选择C-P&R模型和Gompertz模型,采用MATLAB编程实现了全年太阳辐射的逐时化,并开发了相应的界面。利用开发的软件得到了上海气象台站2013年的逐时太阳总辐射、逐时直射数据和逐时散射数据,并和实际值作了比较。结果表明,计算得到的逐时太阳辐射数据符合全年辐射的变化规律,界面化的实现为建筑能耗模拟提供了便利。
Meteorological parameters are the basis of building energy consumption simulation, and hourly solar radiation is one of the most important meteorological parameters in building energy consumption simulation. This paper introduces and compares the time-resolved solar radiation model and the direct-separation model at home and abroad, chooses C-P & R model and Gompertz model, and realizes the annual solar radiation time-shifting by MATLAB programming and develops the corresponding interface. By using the developed software, the hourly-hour total solar radiation, hourly direct solar radiation and hourly scattering data of Shanghai Meteorological Station in 2013 were obtained and compared with the actual values. The results show that the calculated hourly solar radiation data are in accordance with the variation of annual radiation, and the interfacialization provides convenience for building energy consumption simulation.
