IMPROVEMENT OF TECHNOLOGY OF INCREASE OF EFFICIENCY OF THERMOELECTRIC ENERGY TRANSFER BY METHODS OF ALTERNATIVE ENERGY

Abstract

The development of alternative energy and the application of its achievements in the design
and implementation of civilian objects at the stage of their construction and operation requires a com!
prehensive approach to determine the quality characteristics of converters of one type of energy to
another. Currently, the direction associated with the use of Peltier elements in the composition of heat
pumps included in the air conditioning system of buildings is actively developing. The thermoelectric
heating of the premises differs in high efficiency, because in addition to the Joule heat, there is an addi!
tional Peltier heat release. One of the promising areas of this industry is related to the use of thermo!
electric devices, the most famous of which are thermoelectric generators and Peltier refrigeration units.
The acquisition of new thermoelectric materials and the improvement of technologies have ensured an
increase in the efficiency of thermoelectric energy conversion, which has justified their use in the con!
struction and operation of buildings and structures during their life cycle. To increase the efficiency of
thermoelectric converters, a new method and experimental setup of determining the complex of charac!
teristics of thermoelectric modules using a test action formed using Peltier heat is proposed. The values
of the modulus resistance, thermoelectric figure of merit and time constant are determined during the
transient analysis, which results from the periodic change of polarity, passed through the current pulse
module. The algorithm developed reduces the resulting error by reducing the effect on the Joule heat
measurement results and averaging the results.
