| Summary: | The purpose of this research is to measuring the performance of the natural
refrigerator that loaded with water and has been modified in dispenser form. This
dispenser made based on modified of natural refrigerator created by Emily Cummins,
a woman from England. This dispenser has outer shell in the form of ceramics that
pierced in the some points, and inner shell in the form of aluminum. Empty space
between ceramics and aluminum filled with river sand. Water gallon added in the top
of the aluminum and a faucet added in the bottom of so it can be functioned like
dispenser.
Procedure to measuring the performance of the dispenser is using a
thermometer data logger that has 2 water temperature sensors that each of them used
to measuring water temperature inside and outside of dispenser. The data that
obtained from those thermometer sensors saved in the time interval of 10 minutes.
And then his data compared and analyzed until it get estimation of performance from
this model of dispenser.
xvii
The result of this research showed that design of this dispenser can make the
temperature of water inside this dispenser reducing and lower than temperature of
water outside this dispenser. |
