Object-oriented simulation model of thermoelectric devices for energy system design

The contribution presents a flexible simulation model of thermoelectric devices, suitable for the design and control verification of related energy systems, e.g. waste heat recovery by a Thermoelectric Generator. The models are built according to the object-oriented scheme of the Modelica® language. Based on the essential physical effects of thermoelectric materials, the model components are applicable to describe a Thermoelectric Generator as well as a Peltier Cooler. Unlike averaged-properties, steady-state models seen in related works, the presented models can respect the temperature dependencies of decisive material properties in 1D spatial temperature resolution and are capable of describing transient thermal behavior.
