This paper reports the theoretical analysis and the experimental results on the thermal performance test of a double-glazing air-type solar collector using carbon fiber sheet as a collecting material (air-type CF-sheet collector). The model collector was made by 2 m length and 1 m width with 5 steps arranging CF-sheet. Based on this collector, the heat balance equations were designated and the temperatures, thermal efficiency and the overall heat loss coefficients were calculated. On the other hand, the performance test for CF-sheet collector was conducted with a large-scale solar simulator. It was confirmed that the thermal efficiency obtained from the theoretical analysis agreed with that from the experiments, the double-glazing solar collector was superior to the single-glazing one and the overall heat loss coefficient became higher along with increase in ambient temperature.
