Creation of laboratory exercises for Renewable sources of energy
Bajgl, Tomáš ; Jandová, Kristýna (referee) ; Křivík, Petr (advisor)
This diploma thesis deals with the transformation of solar and wind energy into electrical energy by using a photovoltaic panel and a wind turbine. The work gives insight into the Czech Republic’s issue of energetics in the context of historical development, the current state, and the expected future development. The primary attention is given to the renewable sources - the solar energy and wind energy. Basic principles of creation and manipulation of solar and wind energy are described in this work. Two laboratory tasks are created for the Renewable Energy Sources' class as a part of the practical part.
Buildings for education - energy and indoor environment
Čišecký, Ladislav ; Adam, Pavel (referee) ; Hirš, Jiří (advisor)
Diploma thesis deals with evaluation of indoor environment of a school complex in atypical Himalayan alpine environment which is totally dependent on energy originating from renewable sources. Structural design of buildings allows maximum utilization of solar energy which is the only one actually available source of energy in this area. The buildings are de-scribed in detail, as well as measurement conducted in buildings during the last year. The out-comes of measurements are compared with desired values. The thesis is also focused on math-ematical simulations by using BSim software. The output of a building energy simulations is an energy use prediction and design of appropriate measures to improve the current situation.
Optimization of the solar system designed for DHW school canteens heating
Doskočil, Filip ; Zatloukal, Miroslav (referee) ; Bača, Petr (advisor)
Masters’s thesis describes the use of solar energy for solar thermal systems used for domestic hot water heating. It is about the size of the incident solar radiation on Earth. Distributes various types of solar collectors for water heating. It deals with the monitoring, remote management of this system and the design of optimal control used in this area.
Backup power supply with solar panel charging
Křepela, Pavel ; Götthans, Tomáš (referee) ; Kubíček, Michal (advisor)
This project aims to create a backup power source with solar charging for small mobile devices (through USB connector). The charger should store power in a battery that is charged either from external power source or the solar panel. In the introduction, the work deals with the theory of solar cells and batteries. Furthermore, it described the selection of suitable components and design diagram.
Quantification of energy contribution of solar system control unit
Míčková, Petra ; Mišurec, Jiří (referee) ; Zeman, Václav (advisor)
The aim of this work is to study the problems of solar energy and its use in solar systems. Furthermore, to become familiar with a particular solar system for hot water, especially with the principle of energy conversion and features individual components. It is designed and implemented measurement method to determine whether the control unit for the system is important, or would be better even without it.
Optimisation of the house heating by use of the renewable energy sources
Husák, Ondřej ; Frk, Martin (referee) ; Křivík, Petr (advisor)
The thesis contains is familiar with the issues of renewable energy and global warming. Assessing the use of these resources in households in the Czech Republic. The selected family house, perform measurements on the existing heating system. In conclusion, there is suggestions for optimalization system houses, the possibility of linking the with renewable energy sources and an assessment of economic turn.
Combined use of solar energy
Zeman, Miroslav ; Novotný, Jan (referee) ; Matoušek, Antonín (advisor)
This thesis focuses on the combined use of solar energy. The solar conditions in the Czech Republic are listed in the first part. Further, there is the classification of solar collectors focusing on certain types and detailed description of the solar system scheme. The second part discusses the principle of photovoltaic and its historical development considering panels from the first mentions up to the present. The third part is aimed at the selection of the appropriate object and determination of its power consumption. The following chapter discusses the appropriate connection of the photovoltaic systems, the first connection containing only one inverter, the second containing two low-power invertors. The chapter also contains the connection of the solar system and a description of the individual components considering all schemes. The last chapter includes the technical-economical assessment of the whole project and the calculation of the payback period in case of photovoltaic systems.
Low potential heat for electrical power generation
Dobiáš, Jiří ; Radil, Lukáš (referee) ; Bartošík, Tomáš (advisor)
This bachelor’s thesis deals with low potential heat sources for electrical power generation. It mentions primarily low potential heat sources, their distribution by origin and where you can find such resources. Another part deals with the technology that uses low potential heat to heat production of higher temperature level and power generation. These are discussed here with a heat pump, regenerative heating, Stirling engine, solar collectors, Peltier cells, etc. In addition is to their use in practice. The last chapter deals with the replacement of the heater in the regeneration heating coil from the solar collectors. It is thus the use of renewable energy sources. Carry out technical and economic calculations for the real utility of such a plan.
Utilization of renewable energy sources in Czech Republic
Kopička, Marek ; Bok, Jaromír (referee) ; Matoušek, Antonín (advisor)
This thesis deals with consideration of energy facilities structure in Czech Republic. It is depicted in it their evolution from point of: electric energy consumption, structures of energy facilities and electricity prices. Further, is here depicted a production of electric energy for the year 2009, from the point of: produce, sources, consumption and ratio of factories. Of course, the RSE (renewable sources of energy) effect and share of scope on this evolution and structure, is also mentioned here. The next part is pointed to basic description of each sources of electric energy. It is not mentioned here only factories which uses for it´s production renewable primary sources but also another types of factories. Their pros and cons are also summarized. The last part of this work is a thought of realization of fictive project, which could replace a part of steam power plants' share by producing electric energy through renewable sources. It is re-counted and suggested here a few possibilities of this realization from the point of needed installed power and approximate estimation of capital expenditure.
