通过实验对一种新型的内插式真空管空气集热器不同季节工况下的集热特性进行了测试分析,同时研究了南北朝向下集热器安装倾斜角在0°～90°范围内变化对其性能的影响,通过实验得到了空气集热器单管时间常数研究发现不同季节工况稳定工作阶段,该空气集热器以轮廓采光面积为基准的平均集热效率约为50%,在0°～60°范围内改变安装倾角对集热器效率影响不大。90°倾角下集热效率有所下降,平均在40%～50%之间。
Through experiments, a new type of inserted vacuum tube air collector under different seasonal conditions of the heat collection characteristics were tested and analyzed. At the same time, the north and south toward the collector collector tilt angle in the range of 0 ° ~ 90 ° On the performance of the air collector, the single-tube time constant of the air collector was obtained and found to be stable in different seasons. The average collector efficiency of the air collector based on the contour lighting area is about 50% ° ~ 60 ° range to change the installation angle has little effect on the collector efficiency. The efficiency of heat collection decreased with 90 ° inclination, averaging between 40% and 50%.
