Abstract: The energetic analysis of a thermoelectric cooler (TEC) and a thermoelectric heater 11Heat pump. (TEH) is presented, with optimization criteria being unified through the ”x” variable. A number of modes of operation are introduced that are different to those used by several authors for this type of energy converter; such modes of operation are commonly used and have been extensively studied in finite time thermodynamics (FTT) and successfully introduced into linear irreversible thermodynamics (LIT). In addition, new modes of operation are proposed for both cooler and heater. Introducing these modes of operation enables a fuller description of the energy of thermoelectric converters of this type. Finally, the loop-shaped curves concept is introduced and extended to thermoelectric cooler and heater converters in order to clarify the meaning of the dimensionless variables introduced.
