| Air conditioner (AC) is a device functioned to reduce room temperature. AC operates by transfering heat from one room to the outside. The heat is released by the pipes on condenser to the surroundings. Heat released by the condenser can be converted into electricity power by using thermoelectric module. Thermoelectric module is a device to convert electricity into heat rate, and vice versa. This experiment uses 3, 4, and 7 thermoelectric modules along with the usage of 2 different types of fin to know how many modules and which type of fin can produce greater efficiency. The experiment is held for 10 minutes and the data is collected for every 20 seconds. As the result, highest efficiency is reached when using 7 modules with fin 1, which is 0,0017%. Fin 1 efficiency is 99,32%, higher than fin 2 efficiency which is 99,12%. Next experiment is using all of the modules with solar cell to charge powerbank with 10.000 mAh capacity using voltage stabilator module. This experiment is held from 09.00 GMT+7 until 18.00 GMT+7. After the experiment period, the powerbank lights up 1 LED indicator, which indicates that the power is charged less than 25% of powerbank capacity. |
