Isi artikelIn order to obtain more advantage from solar energy and to keep clean the environmental, unused TL tube can be used as glass cover of tubular collector. The design of collector consists of absorber pipe, covered by glass tube with a reflector film on its inner surface and arranged in series without tracking. An experimental study was carried-out to investigate the effect of varieties the absorber position along the vertical eccentricity of cover, and the inlet fluid temperature to collector instantaneous efficiency. The results show that the highest temperature is obtained by positioning the absorber pipe axis below the annulus centerline (negative eccentricity) of glass cover. Increasing inlet fluid temperature or the nwnber of absorber pipes in series, it would give the higher outlet fluid temperature, but the collector overall efficiency would decrease.
