Ditrych, Marek ; Příhoda, Martin (referee) ; Wasserbauer, Vojtěch (advisor)
The bachelor thesis deals with using the electric boiler for extension ancillary services in heating plant. The system and support services are described in the thesis, because the ancillary services regulate an energy deflection. The system and ancillary services are described in the thesis. Thanks to these services an energy deflection is regulated. The thesis describes different types of electric boilers and there functions. In the thesis is shown the possible solution of using an electric boiler in heating plant Opatovice. The cable conduction is designed for a power of electric boiler. For this reason, there is calculated the equivalent warming short-circuit current close to the electric boiler.

Analysis of boundary conditions of ground heat exchangers
Floreková, Skarleta ; Horák, Petr (referee) ; Hirš, Jiří (advisor)
Diplomová práca,, ,,Analysis of boundary conditions of ground heat exchangers,, je primárne zameraná na analýzu okrajových podmienok a hlavných faktorov vplývajúcich na spoľahlivý návrh a prestup tepla plošného zemného výmenníka v oblasti geotermálnych aktivít na kúpeľnom ostrove v Piešťanoch. Posúdenie možných vplyvov na životné prostredie, ako je napríklad vznik tepelných zmien v dôsledku extrakcie tepla vrátane zamŕzania pôdy v okolí potrubia a potenciálneho znečistenia podzemných vôd je taktiež rozoberané. Súčasťou tejto záverečnej práce boli spracované tri numerické analýzy metódou konečných prvkov pomocou softvéru COMSOL Multiphysics 5.6., ktoré sa môžu vyskytnúť v tejto konkrétnej oblasti. Prvá numerická analýza je podrobená štúdii dynamických procesov plošného zemného výmenníka tepla a zeminy nasýtenou vodou pri konštantnej teplotnej okrajovej podmienke pôdy. Dynamický proces zemného výmenníka tepla a nasýteného podložia pri nestálej teplotnej okrajovej podmienke je skúmaný v druhej numerickej analýze. Posledná analýza je vyhotovená na posúdenie prevádzky plošného zemného výmenníka tepla s možnosťou prúdenia podzemnej vody v rovnakej vrstve. Vďaka týmto numerickým štúdiám a výsledkom dynamických tepelných modelov, každá prípadová štúdia obsahuje rozloženie teplôt v zemine, výstupné teploty z výmenníka a vlastný čiastočný záver.

Electric vehicles as energy storage element with renewable energy sources
Janečka, Jaromír ; Horák,, Bohumil (referee) ; Baxant, Petr (advisor)
This master thesis summarizes history of electric vehicles from its inception to present. Vehicles are divided into three groups according to the type of drive, special attention is paid to electric vehicles. Furthermore, typical ways of electric energy storage are presented, especially in the form of electrochemical cells, which are used in electric vehicles. The thesis also describes the situation of electromobility in the Czech Republic, namely government support, distribution companies tariffs, charging infrastructure and available electric vehicles. Finally, the concept of connecting electric vehicles to renewable energy source is described, with financial calculations for three profiled drivers.

Utilization of solar energy for heating and ventilation – solar façades
Mazáč, Ondřej ; Fišer, Jan (referee) ; Jaroš, Michal (advisor)
The objective of bachelor´s thesis „The Usage of Solar Energy for Heating and Ventilation – The Solar Facades“ is the description of nowadays used types of solar facades, the examination of their technical parameters and the estimation of theoretical project on chosen building. The first part is focused on general description of solar radiation, the possibility of its usage in the solar system and and the explanation of its principle. The division of solar facades in terms of their basic criteria is described in the next part. The last part deals with particular estimation of buildings which uses the passive solar system in form of the solar Facade.

Aspects of an experimental solution with the use of geothermal energy in Balneotherapy
Miček, Denis ; Horák, Petr (referee) ; Kabele, Karel (referee) ; Hirš, Jiří (advisor)
The Earth, our home planet is world unlike any other. The third planet from the sun is the only place in the known universe confirmed to host life. We, the humans always headed up to reach set up goals, innovate our technologies and way of living. The fact that, we had never been aware of is that this race to our bright and modern future is destroying our home. By this time, the global temperature arises by 1,9 oC since 1880, 427 gigatons of ice sheets were melted and there are 414 ppm of carbon dioxide particles in our atmosphere. As the trend is changing and we are above to think in green way of living, there is necessity to set up roadmaps and actions plans to stop, eventually decrease the damage which was already caused. The European union started to measure and provide actions plans to decrease the pollution and production of greenhouse gases since the year 1990 – which was set up as reference year for comparison to progress. This arrangement forced the countries to start evaluating the current statuses of their public and industrial sectors in terms of climate changes and provide climate plans for reducing the greenhouse gases. The most important part of climate action plans is to involve the renewable sources of energy into all public and industrial sectors and in this way start the green way of living. Therefore, the investigation and proper understanding of this problems must be the main focus of technical universities and scientific sectors. This dissertation thesis is the summit of 8 years studies and investigation in field of renewable sources of energy, mainly focused on geothermal energy which production in year 2002 was 0 GWh. The main goal is to experimentally analyze designed solutions, elaborated within master and bachelor thesis in real operation of Balneotherapy departments at Slovak Health Spa Piestany, Slovakia from energy, economic and environmental point of view, to set up energy, aqua management and fully understand the way of involvin

Boundary conditions for the operation of thermal energy distribution
Floreková, Skarleta ; Horák, Petr (referee) ; Hirš, Jiří (advisor)
Bachelor thesis ,,Boundary conditions for the operation of thermal energy distribution” is primarily focused on the analysis of the boundary conditions of balneotherapy operation at Slovak Health Spa Piešťany, a. s.. Due to its content, thesis is structurally divided to the analysis of internal and external boundary conditions. In the part of experimental analysis of internal boundary conditions, the incrust was taken from distribution pipelines of natural healing water and subsequently subjected to chemical analysis and to differential thermal analysis. Partial conclusion of this part lists the recommended material list and procedures, leads to elimination of incrustation form on the surface of materials from natural healing water. The second part is focused on the analysis of thermal fields in the subsoil at Slovak Health Spa Piešťany, a. s. and on usage possibilities of ground energy. For initial state, based on measured temperatures in the drills and project documentations, 2D thermal fields were created, by which it is possible to define zones with high and low potential usage of energy. Documents serve for the design way of energy use and for experimental verification of current state of thermal fields.
