Biomass drying
Straka, Lukáš ; Chroboczek, Libor (referee) ; Pospíšil, Jiří (advisor)
The bachelor thesis deals with the importace of drying wood biomass and design drying equipment. The challenge is to design a drying line for drying sawdust for subsequent pelleting. Perform the heat balance calculations and suggest the basic dimensions of the drum dryer output of 100 kg/h of sawdust. Finally, the drying after evaluating the technical-economic terms.

Technical and economic proposal for wind power in the locality Břežany.
Růžička, Tomáš ; Chroboczek, Libor (referee) ; Škorpík, Jiří (advisor)
There is currently a construction project underway in the czech republic (Vesta V52) to build a large wind farm. Due to their size there is a lot of oposition to this venture. My project is a short history of using Wind Energy, the principle behind wind farms and detailed discriptions of Vesta V52 itself. You will also find a theoretical calculation of the produced electricity per year and considered cost and sustainability of the plant.

Wind power production for small-scale energy supply
Pavlik, Richard ; Chroboczek, Libor (referee) ; Pospíšil, Jiří (advisor)
The aim of this work is the issue of utilization of wind energy. At first, the cause of wind, measuring methods of wind direction and speed and the principle of utilization of wind energy by wind turbines are described. Subsequently, the structure of wind turbines, the construction of wind parks, the development of new types of wind turbines and the possibilities of energy accumulation are introduced. In conclusion, the concept and the economic evaluation of wind powered system for small scale energy supply is analyzed.

Trigeneration
Hadraba, Jiří ; Chroboczek, Libor (referee) ; Fortelný, Zdeněk (advisor)
This bachelor thesis is the recherche dealing with cogeneration and trigeneration consecutively. There are described prevailing primary units designated to the transformation of the energy of the fuel in cogeneration units to electricity and heat. The next chapters are dedicated to the absorbing and compression machine cooling. There are also analysed the possibilities of the heat accumulation and the influence of trigeneration on the enviroment.

Solar-thermal system for hot water production
Líčeník, Tomáš ; Chroboczek, Libor (referee) ; Pospíšil, Jiří (advisor)
This bachelor’s thesis deals with questions and proposal for a solar heating system for TUV. Thesis saying how we can use the sun to produce thermal energy when we using solar collectors. The hot water is designed bivalent solar system with a direct connection to accumulative electric heater, which complements the solar system in the winter and a period when the collectors affects not much solar energy. Another section is devoted calculation design of the system, which includes economic analysis aimed at determining the return on investment.

Fuel cells
Ralbovský, Peter ; Škvařil, Jan (referee) ; Chroboczek, Libor (advisor)
This bachalor’s thesis deals with a fuel cells technology, their principle and division. There’s also describes how to obtain hydrogen from natural gas as fuel. Furthermore, there are advantages and disadvantages of fuel cells. At the end of the work there are applications of fuel cells and their use in cogeneration and trigeneration.

Utilizing of wind energy with accumulation
Mészáros, Gabriel ; Chroboczek, Libor (referee) ; Pospíšil, Jiří (advisor)
The introduction of this paper deals with wind-powerplants, their components and distribution according to their construction and output. Technologies of accumulation of energy are described, because the conditions for energy production from wind are not constant (windlessness, storms, etc.). The technologies are compared in terms of economics and technology. A basic design for a system with accumulation is made at the end of the thesis.

Simultaneous utilizing of a heat pump and solar panels in a heating syste
Gongol, Jakub ; Chroboczek, Libor (referee) ; Pospíšil, Jiří (advisor)
My bachelor thesis focuses on simultaneous utilizing of a heat pump and a solar thermal collectors. I introduce principle and types of heat pumps and thermal collectors. I also introduce different sources of low-potential heat, which can be used for a heat pump. In conclusion, heat pump and solar collectors are chosen for a type house. I calculate costs needed for heating house without and with heat pump. These costs are compared and economic return is evaluated.
