Production of cold
Soľár, Slavomír ; Šnajdárek, Ladislav (referee) ; Kracík, Petr (advisor)
This bachelor thesis is focused on description of cool production and properties of two basic cooling units. There are also included calculations for comparing these two units in term of consumption and operating expenses. Part of labour is devoted to applications of units in Czech Republic and rest of World, where the system of district cooling is used. It is also important to acquaint with legislation and regulations, which are related with production of cool and manipulation with equipments and refrigerants.

Cogeneration
Pawlitko, David ; Brázdil, Marian (referee) ; Kracík, Petr (advisor)
This bachelor’s thesis deals with the issue of cogeneration. At the beginning of the thesis, main principles and application of cogeneration are described. Further, various kinds of production of electricity and heat are introduced including comparison of advantages and disadvantages of concrete technology. Another possibility of primary fuel savings are presented too. Thesis also contains Czech and European legislation related to cogeneration, including some changes which bring for year 2013. At the end, heating industry in Czech Republic with its current problems is mentioned.

Heat pumps for heating and hot service water preparation
Valášek, Martin ; Hrnčířová, Michaela (referee) ; Kracík, Petr (advisor)
This bachelor’s thesis is aimed to describe heating and water warming in the detached houses by basic technical devices and there are suggested various types of heat pumps for a particular object. These heat pumps are compared technically and economically. In the beginning of the thesis there is a summary of the possible ways of the house heating and water warming systems, such as heating by electric power, by gas, by solid fuel or the centrally distributed heating. Then the thesis concentrates on heat pumps. There are described various types of heat pumps, also their advantages and disadvantages. There were chosen four main types of heat pumps – air/water, air/air, water/water and earth/water – and with each type there’s constructed a plan for a low-energy house heating. This house is located in Vyškov and there’s thermal loss of 6 kWh and water-warming of a capacity of 260 l per day. At last there were used economical calculations, which shown, that the water/water heat pump has the shortest return rate in comparison with a gas-using heating system – 5 years. Considering the lifespan of the heat pumps – 10-20 years – all the heat pumps are profitable except for the air/air heat pump. The investment in this heat pump doesn’t return.

Fossil fuels use in Czech Republic
Trávníček, Tomáš ; Kracík, Petr (referee) ; Baláš, Marek (advisor)
The aim of the bachelor thesis is to collect facts about fossil fuels and their utilization in the Czech Republic. Firstly, the thesis discusses the fossil fuels and their division in general. The main part of the thesis is focused on mining and utilization of different kinds of fossil fuels in the Czech Republic with the emphasis being put on the brown coal, black coal and the natural gas. The oil and the lignite are briefly dealt with as well. The thesis includes the statistics of the fossil fuels‘ production of the mining companies, the summary of the big energy facilities in the Czech Republic and the mapping of their fuel bases.

Offshore and inland type of wind power
Chromec, Tomáš ; Kracík, Petr (referee) ; Škorpík, Jiří (advisor)
This bachelor‘s thesis focuses on wind energy sector. The first part describes the modern history of this industry. The brief description of the main differences between onshore and offshore wind farms followed an extensive chapter, which describes the diversification of wind power solutions and diversification in the case of wind farms located on the sea. Fluctuating needs for backup power sources in this work is included in chapter, which briefly describes the most appropriate energy storage devices. This is followed by section dealing with the economics of wind turbines. Possible negative impacts of wind energy are discussed in the final chapter about environmental impacts associated with wind power applications.
