Abstract
A high performance solar collector array for a solar assisted drying system has been designed fabricated and tested at the Solar Energy Research Park Universiti Kebangssan Malaysia. The solar collector is of the double-pass type and the second or lower channel of the solar collector is filled up with porous media. This will increase the outlet temperature and the performance of the system. The collector width and length are 120 cm and 240 cm. The upper channel depth is 3.5 cm and the lower depth is 10.5 cm. The solar collector consists of 6 solar collectors arranged as 2 banks of 3 collectors each in series. The collectors are combined in series using internal manifolding. Air enters the inlet of the upper channel in the first collector and flows in the lower channel. Next the air flows to the second collector. The lower channel of the third collector is the air outlet from the first bank. In the second bank air flows in the upper channel of the sixth collector and the outlet air is the lower channel of the fourth collector. The outlet air from the third collector is mixed with the air outlet from the fourth collector. A temperature of 90 degree centigrade can be reached at a solar radiation level of 800 W/m superscript 2 and mass flow rate of 0.06 kg/s.
