on video Seebeck & Peltier Effect - How Thermocouples & Peltier Cells work?


The Seebeck effect is when electricity is created between a thermocouple when the ends are subjected to a temperature difference between them. The Peltier effect occurs when a temperature difference is created between the junctions by applying a voltage difference across the terminals. A hot surface in contact with the cold junction of the TE will be cooled down and vice versa, a cold surface in contact with the hot junction will be heated up. This effect can be used as a heat pump for heating (TEH) and cooling (TEC) applications. Some useful references could be found in Refs. [4–8].
