Abstract: An experimental investigation of the effect of power on thermoelectric cooler box performances was conducted. The cooler box size used was 408 mm × 326 mm × 538 mm, and the type of the thermoelectric used was TEC1-12706. The thermoelectric was run using direct current powers ranging from 21W to 51.27W. Moreover, to add cooling load inside the cooler box, heat from drinking water of 600ml volume was added inside. The experiments were recorded within 21000s. At steady-state conditions, the cooling load was dominated by the conduction heat transfer mode. This has not been revealed in the published paper concerning the thermoelectric cooler box. The experimental coefficient of performance (COP) decreased with the power but increased with time. This was due to the conduction heat transfer rate domination. Meanwhile, the theoretical COP decreases with time, and the experimental COP was also compared with the COP resulted by the previous researchers. |
