利用日均太阳辐射模型与集热器能量输出模型对平板型和真空管型太阳能热水系统水量配比进行建模分析。结果显示,模拟的水量配比与实验测试吻合较好,相对误差在10%以内。基于我国五大气候分区133个城市的气象数据,利用此模型对集热器件与建筑南立面大角度(70°～90°)集成后的太阳能热水系统的水量配比进行模拟计算与分析。为便于工程应用,利用多项式线性回归技术对水量配比与气象参数间的关系进行回归分析与整理。给出各类气候区夏半年和冬半年太阳能热水系统水量配比与气象参数间的回归关系式,为太阳集热器件与建筑南立面大角度集成的水量配比的优化提供方便。
The daily average solar radiation model and collector energy output model were used to model the water ratio of flat and vacuum tube solar water heating systems. The results show that the simulated water ratio is in good agreement with the experimental test, and the relative error is within 10%. Based on the meteorological data of 133 cities in the five major climatic zones in China, this model was used to simulate and analyze the water quantity ratio of the solar water heating system integrated with the large angle (70 ° ~ 90 °) between the heat collecting device and the south side of the building. In order to facilitate the application of engineering, the relationship between water ratio and meteorological parameters is regressed and analyzed by polynomial linear regression. The regression equation between the solar water heating system and the meteorological parameters in summer and winter is provided for all kinds of climatic zones, which is convenient for the optimization of large-scale integration of solar collector and building south elevation.
