Abstract
In the global community, increasing attention is paid to alternative energy sources. The Peltier module is the simplest converter of thermal energy into electrical energy and vice versa. At this stage of development of industry, technology, electronics and microprocessor technologies, the Peltier thermoelectric elements are mainly used as heat pumps. Due to their simplicity, high reliability, small size, relatively low cost and other advantages, the Peltier thermoelectric modules are considered as obvious sources of electrical energy. The study was made to determine the possibility of using the Peltier thermoelectric modules in the qualitative conver-sion of thermal energy into electrical energy, as well as to establish the most efficient modes of operation of the Peltier elements as generators of electrical energy. In the course of the research, work was done aimed at creating a model, analyzing various static modes of power generation and studying the Peltier modules in the mode of an electric power generator. The operation modes of the elementary cell of the Peltier thermoelectric module were simulated in the ANSYS Workbench environment. The mathematical analysis of the simulation results was performed. The performance characteristics of the Peltier thermoelectric elements were determined, the results were processed. The conditions of maximum efficiency of conversion of thermal energy into electrical energy by the Peltier thermoelectric module were revealed. The optimal modes should be considered to be heating one of the sides of the Peltier module to a temperature close to the permissible value. The operation modes of thermoelectric elements were determined, the results were processed. A device based on the Peltier thermoelectric modules can be used as a portable accumulator battery charging device for gadgets and television and radio communication facilities.
