| Abstract | ||||
| The creation of air conditioning and refrigeration was one of the biggest achievements. This study aimed to see how well the Peltier cooler system, to store vegetables and fruit, performed. To test performance, a thermoelectric module with (1, 2, 3, and 4) with and without fans, as well as two methods of attaching Peltiers, was employed (serial and parallel). The performance of the cooling system is determined by collected and analyzed data from the measuring system. The temperature distribution on each component of the cooling system is recorded using thermocouples connected to the data acquisition. Temperature for green bean cooling was 5 ˚C, which provides perfect cooling for 14 days by 4 Peltiers, serial connection electric at average cooling load of 525.51 W in just 5 min without freezing, with the use of a fan. The parallel connecting increases the consumed power from 2.1 W to 16.8 W therefore the serial connection is reduced the power consumption to 0.26 W. The coefficient of performance (COP) values were reduced with the operating time to be 0.08 and 0.07 in parallel and serial connection respectively and one Peltier, but with the 4 Peltiers the COP values were 0.17 and 0.08 in parallel and serial connection. | ||||
