摘要
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 modeling analyses of the mass area ratios of the flat-plate and evacuated tubular solar water systems were conducted based on the daily solar radiation model and the solar collector energy output model in the paper. The results show that the simulations of the mass area ratios are well consistent with the experimental data and their relative errors do not exceed 10%. The mass area ratios of the solar collector integrated in large-tilt-angle （70°- 90°） with south facades of the residential buildings in five meteorologic regions including 133 cities in China were calculated and analyzed. For convenient use in practice, parameter correlations between the mass area ratios of solar hot water systems and the main meteorologic variables were analyzed by using the linear polynomial regression technique. The correlations of solar hot water systems used in summer and winter were been given in the paper. These results give a useful tool to calculate and improve the mass area ratios of the solar collector integration in large-tilt-angle with the south facades of buildings.
