Terms and Definitions. Thermoelectric Modules

Thermoelectric Modules, (TEMs), also called as Peltier Modules or Thermoelectric Coolers, (TECs), are semiconductor-based a solid-state active heat pump which transfers heat from one side of the device to the other, with consumption of electrical energy, depending on the direction of the current. The Peltier effect consists in releasing or absorbing of heat at the junction of two different conductors when DC flows through the junction. Vice versa, the Seebeck effect at the same modules allows converting thermal energy into electricity. Thermoelectric module, used for generating of electricity, usually called Thermoelectric Generator (TEG).
