Peltier effect Definition, Discovery, & Facts Britannic

  1. Peltier Effect and T Effect. If the junctions of a thermocouple are kept at constant temperature and a current is passed through the wires of the thermocouple, it has been found that one of the junction is heated and the other junction is cooled. That is heat is produced at one junction (junction which is heated) and absorbed at the other.
  2. Peltier systems require more energy input than comparable compressor-based systems. However, while heat is emitted from Peltier systems, it is comparatively less than in compressor-based systems. This means that there may be some savings in terms of air conditioning load in the area where the unit is housed, which could help offset the energy efficiency differential
  3. When electricity is passed through the module, electrons move in one element and positive holes move in the other element, this is called the Peltier effect. This allows one side of the substrate to absorb heat and the other to radiate heat, so the hot and cold sides to be switched depending on the current direction
  4. ed by the principles of irreversible thermodynamics
  5. Fig. 1 Peltier Effect. Consider a Copper-Iron (Cu-Fe) thermocouple having both the junctions at the same temperature. If a current is passed through this thermocouple in the direction as shown in figure 1(a), heat is absorbed in the junction 1 and evolved at the junction 2
  6. An effect closely related to the Peltier Effect is the Seebeck Effect. The Seebeck Effect is named after German physicist Thomas Johann Seebeck who discovered the effect in 1821, however, it had actually been observed as far back as 1794 by Italian scientist Alessandro Volta
