Study on Evacuated Tubular Solar Air Collector with Inserted Tubes

Abstract:

This paper aims to study the heat collecting efficiency of the solar air collector with ten groups of single pipe in parallel. The simulations and experimental verification are carried out to obtain the best angle and air inlet flow rate. The result is that when the angle of the collector is 45 °and the inlet flow rate is 48.6 m³/h (2.7 m/s), the heating effect is the best for the solar air collector we have studied in this article. The average collection efficiency of it during stable operation can reach 65%.The simulation results are consistent with the experimental results. In practical application the results can provide a theoretical foundation to choose the appropriate flow rate and angle of the collector.
