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.

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.

Heat pumps
Kubik, Martin ; Fortelný, Zdeněk (referee) ; Chroboczek, Libor (advisor)
The Bachelor thesis contains a brief introduction to heat pumps problems and analyses a principle of their operation. In this thesis there is further mentioned partition and characteristics of compressors, heat exchangers and refrigerants. In the thesis there are described heat pump types, which are: air–water, water–water and ground–water, including advantages and disadvantages and conditions of realization. The last part of the thesis deals with calculation of investment in the case of using heat pump for hot service water heating and its analysis.

Solar system
Tuhovčák, Ján ; Fortelný, Zdeněk (referee) ; Chroboczek, Libor (advisor)
The bachelor thesis describes the issue of the domestic water heating by solar systems and the conditions of this system’s usage, its advantages and disadvantages are mentioned. Part of this paper analyzes the main components of solar system and there is a list of solar panels available on the market. The second part of this thesis deals with specific application of a solar system in the locality of Brno. The concept of the system consists of absorption area calculation, energy balance and the system’s financial analysis. Financial repayment time is interpreted separately for the conditions in Czech Republic and Slovakia. If the government grant is considered in the calculation, the financial repayment time is economically interesting, otherwise it is disputable. The environmental contribution is in every case unambiguous.

Renewable energy sources in CR
Pokorný, Tomáš ; Chroboczek, Libor (referee) ; Fiedler, Jan (advisor)
Renewable energy sources in CR with a view to small water power plants. Bachelor's thesis of common bachelor studies of 3th years. This bachelor's thesis is technical literature search. The contents of this search is an analysis of a mechanical equipment of that are used for small water power plants, analysis of history and present state of exploitations water sources and display of elementary performance calculations for a given locality.

Renewable energy sources in CR
Dohnal, Petr ; Chroboczek, Libor (referee) ; Fiedler, Jan (advisor)
This bachelors thesis is a technical recherche of using renewable energy sources in Czech republic which is specialized on waterpower. In this work are shortly described kinds of productions energy (electric and heat) from wind power, solar radiation, biomass, geothermal energy and the largest part deal with processing waterpower.

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.

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.

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.
