| Summary: | Alternative energy is now becoming concerned globally. The energy shortage
and problem due to deforest had made people try to exploit rene
wable energy in
order to tackle the problem. Although solar cooker is still not common but it had
been proved that it can be a good tool if it is well designed and constructed. Solar
box cooker (SBC) that was designed and constructed by previous student, M
r. Then
Kuck Shee, still had a lot of potential for improvement. In his thesis, he did not study
the humidity in the SBC’s chamber. In fact, humidity had effect on the efficiency and
performance of the SBC. Therefore, fundamental of SBC, characteristic of
humidity,
and other factor that affect the performance of SBC was studied in the present work.
Then, based on the experiment result, it is found that air in the SBC’s chamber is
finally saturated and this stimulate more heat lost to the environment as the
air
temperature drop. Hence, the temperature of the cooker will drop greater than the
case where the air does not saturated. In order to reduce the effect of the humidity to
SBC, it is recommended that humid absorbent may be able to be put inside the
cook
er chamber when cooking but it need to be made sure that the absorbent would
not affect the safety of the food. Also, ceramic can be put inside the SBC’s chamber
to increase the heat storage and efficiency. |
