Thermoelectric coolers operate according to the Peltier effect. The effect creates a temperature difference by transferring heat between two electrical junctions. A voltage is applied across joined conductors to create an electric current.Click to see full answer. Subsequently, one may also ask, can you put ice in a plug in cooler? CON: Thermoelectric coolers can’t get wet (inside or out). Regular coolers – as well as most portable refrigerators – work just fine if they get wet inside. But if you put some ice inside your thermoelectric cooler, and that ice melts, it can damage the peltier plate in your cooler and ruin it.Also, can a Peltier module cool a room? Peltier junctions produce a temperature difference between one side and the other. This is the temperature they cool with respect to. If they are 60 degrees C on the hot side, and 40 degrees C on the cold side, then it is working and cooling. Sure, both sides are above room temperature, but that doesn’t matter. what is the best plug in cooler?
