초록

The thermal performance of the glass evacuated tube solar collector is numerically investigated. The glass evacuated tube solar collector consists of a two-layed glass tube, a copper tube, and the working fluid. The length and the diameter of the glass tube are 1,200mm and 38mm, respectively. The diameter, thickness, and length of the copper tube and the flow rate of air are considered as the important design and operating parameters of the collector. The effect of these parameters on the thermal performance of the collector are investigated. The results show that as the diameter, the thickness, and the length of the copper tube increase and the flow rate of the air decreases, the thermal performance and the outlet mean temperature increase.
