Cogeneration unit linked with absorption heat pump
Kürthy, Marián ; Fiedler, Jan (oponent) ; Pospíšil, Jiří (vedoucí práce)
This diploma work aims to evaluate the functional connection of the cogeneration unit with an internal combustion engine and an absorption heat pump to increase the heating effect of the cogeneration. The aim of this work is to design a functional system and evaluate it from the technical - economic terms. In the introduction of the theoretical work the applied cogeneration technologies used in combined heat and power production are presented. Then there is described the principle of heat pumps, their basic components and theoretical comparison of compression and absorption heat pumps. In the practical part of this work is for a specific application in the area Technická 2 proposed merger of the cogeneration unit with an internal combustion engine and an absorption heat pump, while detailed design parameters used in absorption heat circulation are set. At the end of this paper there are designed various heat exchangers of applied absorption heat pump. The final part of the work is devoted to technical - economic assessment of applied design. In this assestment three different types of heat pumps are compared: Absorption heat pump with working solution H2O-LiBR, absorption heat pump with working fluids NH3-H2O and compressor heat pump.

A fuel cell, as an alternative source of electricity
Kürthy, Marián ; Šen, Hugo (oponent) ; Pospíšil, Jiří (vedoucí práce)
The work deals with fuel cell technology, the principle of fuel cells and their division. Also there is presented an option of natural gas utilization as a fuel for fuel cells in this work. In the end of this work two scenarios of fuel cell usage in microcogeneration are introduced and there is also a technical economic evaluation of fuel cell microcogeneration unit used in these scenarios.
