Abstract

Thermoelectric refrigeration has advantages that other refrigeration systems do not have, such as accurate temperature stability settings. In some applications, like medicine purpose, this feature is very important. This study examined the performance of a thermoelectric cooler box with a cold sink that fills with a Phase Change Material (PCM). The cooler box has 240 mm x 180 mm x 130 mm of the inner dimension and is supplied with two thermoelectric modules with 133-watt DC power. The power supply to the module was controlled by a thermo-controller and set to interrupt the supply if a temperature condition was achieved during the test. The purpose is to exchange the cooling supplied of thermoelectric with PCM for reducing the cooler box’s power consumption. The result shows that PCM was able to hold the temperature of the cooler box for 24 minutes. The result also indicated that Bio-PCM has potential energy storage in thermoelectric application devices compared with commercial PCM.
