Optimasi Penyerapan Panas Memanfaatkan Energi Matahari pada Kolektor
Abstract: Solar energy is a
renewable energy that can be utilized for human needs for various purposes such
as electricity, heating, hair, and so forth. Solar collector is a device that
collects solar energy and converts it into thermal energy and redirects the
energy back into the fluid. Three variations of barrier angle were prepared in
order to optimize the absorption of solar energy in a collector. Multiple pass
turn were utilized to maximize the heat absorption. The size of the collector
is 250 cm × 85 cm. Each side of absober box is coated with aluminum of 10 mm
thick. Iron sand is used as absorber with thickness of 6 m. The collector box
is tilted with 15° angle. Measurements were carried out for each multiple pass
turn angle ; 130°, 180° and 90°. The tests were carried out in an open field in
front of the Faculty of Engineering, Syiah Kuala University. The results show that
temperature tends to be similar for all three variations of barrier angle. For
the barrier angle of 130°, the highest temperature achieved was 93.3°C during
12:00 to 13:00 pm. The highest temperature achieved for the other two
variations are 91.2°C for the barrier angle of 90° and 90.2°C for the barrier
angle of 180°.
