Thermoelectric Power Generation System
Brázdil, Marian ; Nerud, Pavel (referee) ; Pospíšil, Jiří (advisor)
In the last decade there is a rising interest in thermoelectric applications. Thermoelectric generators enabling the direct conversion of the heat into the electricity become attractive. This fact is caused by the demands of environmental operation and saving primary resources. Scientists intensively investigate and develop new materials and structures suitable for these applications. The efficiency of the thermoelectric conversion progressively increases. Unfortunately we have no available materials with sufficient thermoelectric properties which could provide cost-competitive price. Thermoelectric generators seem to be useable devices. For example, in case of the unused waste heat using of the thermoelectric generator can increase the overall effectiveness of the unit despite the low efficiency of the generator. This master thesis deals with the issue of the Peltier modules representing the main part of the thermoelectric generators. The physical principles and structures of the thermoelectric modules and the possibility of thermoelectric power production are described here. In the practical part of this thesis the design of the low power generator utilizing waste heat from biomass boiler Verner A 251.1 is proposed.

Thermoelectric cooler construction
Murgaš, Martin ; Šnajdárek, Ladislav (referee) ; Brázdil, Marian (advisor)
Bachelor thesis will concern description of Peltier modules and detailed description of thermoelectric phenomena’s on which is principle of these modules based on. Thermoelectric materials and their properties will be mentioned as well as different applications of Peltier modules. Heat losses of the cooler will be described. Onwards it describes mathematical model of Peltier modules and their coefficient of performance. Also mounting of modules, types of power supply and types of regulation are mentioned. Experimental part consists of calculation and designing of cooling assembly.
