| 摘 要： | 对建筑物平屋顶水平面上南北向和东西向放置圆柱形吸热体真空管集热器的日、年能量收益,以及上述两种集热器管中心距与能量收益的关系进行了分析研究。结果表明:冬季水平面上东西向管集热器比南北向管集热器的日能量收益明显要高。水平面上南北向管集热器和东西向管集热器在管中心距等于2.0D时,可分别得到管中心距为5.0D时年能量收益的91%和96%。 |

| Abstract: | According to the Clear-Day Model,the daily energy gain and its annual variation for different center-to-center distances of evacuated collector with cylindric absorber in two different axes installation on horizontal plane are studied.The results show that the east-west axis get more solar energy gain than that of the collector installed in north-south axis during the winter.When the center-to-center distance of tubes collector installed in north-south axis and east-west axis are 2.0 times of the outer diameter of tube,the annual absorbed solar energy are 91% and 96% of that gained by the collectors when the tube distance is 5.0 times of the outer tube diameter of tube,respectively. |
| Keywords: | evacuated collector energy gain horizontal plane east-west axis installed collector north-south axis installed collector |
