Biogas cogeneration
Miča, Martin ; Chroboczek, Libor (referee) ; Pospíšil, Jiří (advisor)
This bachelor´s thesis discusses biogas cogeneration. The introductory part deals with biogas production and its treatment before energetic use. The main body of the thesis focuses on various methods of energetic utilization of biogas and biogas processing in particular biogas station in Nové Město na Moravě. From the realised measurements there were created graphs of produced, sold and consumed electrical energy depending on days and average daily temperature. The last part of the thesis gives possibilities of waste heat recovery in wood dryer.

Separation and storage of CO2
Odložilík, Martin ; Chroboczek, Libor (referee) ; Pospíšil, Jiří (advisor)
The main objective of this work is to clarify the methods for CO2 capture and storage as an option to limit global warming. The first part is further explained by a phenomenon known as the greenhouse effect, there is illustrated his principle, the effects of climate change, the main factors increasing its intensity and its possible reduction. Framework of the second part is description of the technologies and methods of CO2 capture and storage, the individual steps in these processes and also the possible development in the future. Next chapter discusses the pilot research programs and application of referred technologies to in practice. The last part of this work is devoted to the economical aspect of the problems.

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.
