11. CONCLUSIONS
The symmetrical, interconvertible LTspice-model of the Peltier element, which converts electricity into the heat and heat into the electricity, was developed.
Model of the Peltier Element is described by a small set of parameters, such as: the Seebeck coefficient, electrical resistance, thermal resistance, heat capacity. The model parameters are chosen based on the results of experimental measurements.
The developed model can be useful both in the calculation of the cooling systems for electric and thermoelectric generator, and in the educational process to illustrate the work principles of the thermoelectric elements.
