摘要
该文以昆明和北京为例,对我国南北地区分别选用平板型管翼式集热器和圆柱吸热体真空管集热器进行了模拟计算。结果显示,水平面上日均太阳辐射、环境温度、屋顶方位及倾角对集热面积补偿有不同程度的影响;其中,屋顶方位角和倾角是影响集热器处于非正南和正南方向且最佳倾角时采光面积之比A/A0的主要因素。本文的研究成果可为太阳能建筑一体化设计提供部分有价值的参考数据。
Taking Kunming and Beijing as the examples, area compensation of the flat plate tube-fin solar collector used in southem region and evacuated tube collector with cylindrical absorber utilized in northem region has been theoretically calculated, respectively. The results show that the horizontal daily solar irradiance, ambient temperature, roof azimuth and tilt angle have an influence on area compensation to some extent. The roof azimuth and tilt angle are main factors that influence the value of area ratio A/Ao of the non-south-facing collector to the south-facing one with the optimal tilted angle. The investigations results will be valuable for the designs and applications of solar energy integrated with the buildings.
