State of photovoltaic in the Czech Republic
Lukášek, Kamil ; Bača, Petr (referee) ; Vaněk, Jiří (advisor)
Photovoltaic in the Czech Republic has gone through significant development during last few years. The thesis describes physical principle of converting solar energy into electrical energy using photovoltaic cells. Photovoltaic power plant is a set of technologic components connected together to utilize solar energy and convert it into electric energy that could be distributed to electric power network. Review of the photovoltaic development in the Czech Republic and the list of the biggest operational photovoltaic power plants present important data for assessment of the current status of photovoltaic technology in the Czech Republic. Chapter operations and maintenance of photovoltaic power plants summarizes the most common causes of failures and presents diagnostic tools for service requests. Due to legislative changes, hybrid photovoltaic power plants construction has been prioritized as it is economically more efficient now. Construction of new hybrid photovoltaic power plant was assessed analytically using SWOT analysis that evaluates strong and weak sides of the projects in comparison with opportunities and threats of construction. After evaluation of obtained data the next steps of the hybrid photovoltaic power plant’s construction plan are proposed. The first part of hybrid photovoltaic power plant design contains PVGIS program's data evaluation, which provides sunlight intensity information for specified area. Obtained data were used in the second part of the design to determine proper components selection for family house hybrid photovoltaic power plant. Finally the economic view of the design and return of investments were assessed.

Energy-conscious renovation of family house
Bohutínský, Zdeněk ; Vendlová, Lucie (referee) ; Horák, Petr (advisor)
The aim of the thesis is a design of the best energy measures for a family house. At first there is carried out an energy assessment of the building. According to results of that survey there are drawn up some variants of measures. Furthermore, based on energy assessment results there is elaborated a project for reconstruction of the heating.

Using of Renewable Energy Sources for Family House Supply
Varmuža, Jan ; Macháček, Jan (referee) ; Toman, Petr (advisor)
This work is concerned to analysis and evaluation of present recoverable energy resources and position EU to them. In study is provided comparison of recoverable resources (biomass, water, wind, environment energy, and sun). The details are noted for all single cases. As the next addition are included various techniques „how to obtain and convert them“. In study are also noted which necessary equipments must be used and their proper location. In practical part is done comparison of barrier-layer photocell from polycrystalline and monocrystalline silicon and water insulating foil „EVALON SOLAR“. For comparison was taken only produced energy. Next step was financial analysis of each single system and comparison with pay-off in case that invested sum (actual price) was placed to bank under time deposit and share capital fund. During analysis of financial evaluation was found, that more suitable is system from polycrystalline silicon. Because of investors main condition is financial aspect, so for realization will be recommended system from polycrystalline silicon.

Using Solar Energy for Refrigeration and Air Conditioning
Chládek, Petr ; Baxant, Petr (referee) ; Mastný, Petr (advisor)
This thesis is dealing with the usage of solar energy for cooling and air-conditioning. Notification of the quantity of solar power which incidents to the Earth, types of solar power collector and discribes systems which are applicable for cooling and air-conditioning. Next part deal with calculation and proposal of combined system for warming-up domestic hot water, heating a bit more and cooling. In the last part I solve the capital expenditure and system´s economic return.

Manufacture of aluminium alloy castings
Moravec, Lukáš ; Lána, Ivo (referee) ; Záděra, Antonín (advisor)
This thesis deals with the production of castings of aluminum alloys with a focus on a comparison of the melting process in the gas, crucible, tilting furnaces with melting in gas, shaft furnaces. Resolves proposal links the advantages of both types of melting furnaces into a single unit. The work includes economic evaluation of cost and projected savings in the operation of the new kiln unit.

Solid Fuel Boilers
Skočík, Lukáš ; Špiláček, Michal (referee) ; Baláš, Marek (advisor)
This thesis is engaged in heating of the family house by solid fuel boilers, both fossil fuels and the modern forms of biomass. The first section describes and explains the properties, composition and important characteristic quantities of these fuels. It also discusses the classification, description and processing options of solid fossil fuels and biomass.Then they are briefly described the principles of combustion boilers for these fuels along with their properties, advantages and disadvantages. The last section focuses on the selection of a suitable boiler fuel for the selected reference house.

Design of a space heating system with an air-water heat pump and bivalent heat source
Skočík, Lukáš ; Elcner, Jakub (referee) ; Katolický, Jaroslav (advisor)
The thesis is engaged in complete reconstruction of a heat system of a family house with higher heat loss, i.e. heat source, piping and radiators. As a heat source is chosen air-water heat pump. Heat system is designed with panel radiators with regard to minimum building interventions. A required power for hot water heating is calculated and selected a heat pump from suitable power range in combination with storage tank with hot water tank. The bivalent point is determined, as backup source are heating elements installed in storage tank. Drawings and circuit diagrams with safety elements are attached. In the end is calculation of estimated return.
