| dc.description.abstract | The study was conducted through an experiment heating water with solar cookers box
type absorber equipped and oblique that has collector area of 0.59 mx 0.59 mx 0.59 m
and 0.9 m. The study was conducted in fine weather conditions. In the solar cooker can
be tilted absorber is expected to supply heat to the principle of natural convection.
Experiments carried out by heating the water as much as 1, 2 and 3 liters of reach
temperatures 87,83oC, 77,97oC, and 88.74 ° C with efficiency 4.357%, 6.091% and
10.419%. The difference in temperature is influenced by the magnitude of the intensity
of radiation during the tests with large intersitas average radiation measurements 595.9
W / m 2, 478.5 W / m 2, and 619.26 W / m 2. Efficiency increases with increasing the
capacity of the water tested as well as the rate of energy absorption by water. The more
energy that is absorbed by water, the efficiency will increase as well. Heat energy
received 1 liter of water during the test, 2 liters and 3 liters is 0.2397 MJ, MJ 0.423,
and 0.735 MJ of radiation energy absorbed by the absorber at 5.5 MJ, 6.94 MJ and
7.05 MJ | en_US |
