This experiment was conducted in a 1-pyeong cold room. Looking at the experimental results, it can be seen that the power consumption is twice as high when the thermoelectric module cooler is used compared to when the steam compression type cooler is operated. As is commonly known, steam compression coolers have a COP of about 3.0 in commercial coolers such as air conditioning systems and refrigerators, and the COP of coolers using thermoelectric modules is about 1.0, showing a performance difference of about 3 times. The reason for this difference is that the heat conduction fin material and shape were optimized, and the defrosting power consumption was relatively small in the thermoelectric method. The performance of thermoelectric devices shows that although there are still many improvements to be made over existing methods, they can exhibit sufficiently different advantages depending on the system.
