摘 要: | 太阳能集热器的集热量与集热器的安装倾角有关。在竖排集热器朝正南向放置时,其集热量与集热器安装倾角之间存在一定的函数关系。结合拉萨地区典型年气象资料,通过对不同安装倾角真空管太阳能集热器在整个采暖季的集热量动态计算分析和寻优,结果表明:真空管型太阳能集热器在该地区的最佳倾角为46°,考虑到拉萨整个地区的纬度和气象条件不同,建议最佳安装倾角范围为40°~50°。

Abstract: | The amount of heat collected by solar collectors relates closely with the collector inclining angle. When the collector faces to south, we can determine the relationship of the collected heat amount with the collector angle. With analysing the heat collected instantly by the evacuated tube solar collector which is located in different inclined angles, it is found that best angle in this area is 46°. Considering LHASA geographical position and weather condition, appropriate range of the collector inclining angle should range from 40° to 50°. |
