Design and Experimental Analysis of Thermoelectric Refrigerator

Thermoelectric refrigerator (TER) is a new option because it can convert electricity into cooling, which is useful and effective in food preservation, Vaccines, medicine and electronics device. especially, it reduces the use of refrigerated gases and reduces the release of chlorofluorocarbons (CFCs), which cause climate change and global warming. in response to all the above problems and solutions, the refrigerator is designed with has outside of 58 cm  44 cm  33 cm. the cool part of the inside of the refrigerator has 13 cm  12 cm  22 cm. the refrigerator uses a Thermoelectric Module type TEC1-12715, Microcontroller Arduino Nano, LCD, cooling fan and Relay too. as a result, experimental have shown that the total current consumed is about 1,5 A equal to about 18 W of power at a voltage of 12 V DC. and capable of lowering the temperature inside the refrigerator from 31,25 ° C to 1,31 ° C in about 60 minutes. And reduced the temperature in the heat cabinet to about 29,94 ° C. as for the temperature in refrigerator has 0,5 liters of water varies from 30 ° C to 4,81 ° C. and then, temperature in refrigerator has 1 liter of water varies from 29,27 ° C to 5,19 ° C. further, temperature in refrigerator has 1,5 liters of water varies from 30 ° C to 9,38 ° C. furthermore, temperature in refrigerator has 2 liters of water varies from 29.52 ° C to 10.50 ° C.
