本研究是探討具迴流裝置的朝下加翅型太陽能二子集熱器，在固定吸收板面積及相同操作條件下，改變迴流比值及隔板位置，來探討迴流比值及隔板位置對於加熱器效率的影響，並找出最佳隔板位置，以獲得最大熱傳效率。
A study on the improvement of recycle on the collector efficiency of adouble-pass rectangular flat-plate solar air heating system containingtwo subcollectors of the same length and the same width with the totalcollector area fixed. The solar air collectors with air flowing overand under the absorber were considered in this study. The results showthat a suitable adjustment of the ratio of these two subcollectorsresults in the enhancement of heat transfer efficiency.
