This research aims to devise fan cooling nature of ice and salt bins from the chaff by a standby letter of the second floor. The separation between the ice and the chaff. The hole in the cap of the fan and then to 12 V. The effect of salt on the ice that affect temperature. When the ratio of ice to salt is 10: 1 and 10: 2 by experimenting fans, slow and fast for 70 minutes, then hold the temperature every five minutes to rally 14 times per cycle
performed using the statistical calculation is. the average percentage of average and standard deviation or variance. The results showed that
the amount of research on the effects of salt on the ice temperature. When the ratio of salt to the ice. 10: 1 Open fan slow. The average temperature is 21.9785714286 A variance is 1.102432376 5.015941922 degrees as% when the fan speed. The average temperature is 23.0071428571 1.033050765 degrees with a degree of variance accounted for 4.4901306147%
of the amount of research on the effects of salt on the ice temperature. When using ice to salt ratio is 10: 2 Open fan slow. The average temperature is 22.4428571429 There is a degree of variance is 0.2182290235 0.9723762982% when the fan speed. The average temperature is 22.7928571429 0.5204526791 degrees with a degree of variance accounted for 2.2834025407%.
