Evaluation of new possibilities of using thermoelectric generators in systems of renewable energy sources (RES)

Abstract

This paper presents an analysis of the application of new technologies in the design of thermoelectric cooling systems, presented the results of the comparative analysis of classical thermoelectric system and the thermoelectric system with the spatial orientation of the heat transfer sides. New thermoelectric systems are beginning to compete with traditional ways of energy transformation up to several hundred watts. To extend the range of applications of thermoelectric systems, it is necessary to use new design methods and new design solutions that will more effectively convert heat losses into useful energy for future use. This paper presents the results of a comparative analysis of conventional thermoelectric module and the thermoelectric module with the spatial orientation of the parties. It is shown that the efficiency of the thermoelectric module with the spatial orientation of the parties in the current in 4A 36% higher compared to the classic thermoelectric module and 43% higher when the current is 8A. The results of the research have shown that the efficiency of the thermoelectric modules to a greater extent influence not electrophysical characteristics of thermoelectric junctions, and the technical decisions when designing and designing. Studies have shown that further work to increase the efficiency of thermoelectric systems should be conducted in the field of improvement of structure of the thermoelectric modules. Using the known topology emitted or absorbed heat from the thermoelectric module can be moved to side to distribute it over a larger area or concentrate on a smaller area. With the increase of its efficiency, thermoelectric modules can compete with traditional heat pumps in the field of higher capacity and will be able to expand your range of applications.
