Solar systems utilization for family house energy demand
Šamanová, Jaroslava ; Toman, Filip (referee) ; Sitek, Tomáš (advisor)
Solar systems are more and more common part of residential houses. Main reason for this, is that solar elements are state-supported with subsidies, which is reducing payback time of these investments. At the same time, the prices for these systems are dropping. The state support is connected with effort to reduce dependancy on non-renewable energy sources, e.g. coal powerplants, which are polluting atmosphere. State administration i salso the reason for large scale solar powerplant constructions, which are, according to some opinions, misshaping the landscape and covering large areas of sometimes fertile land.
Connection of Solar Power Plant and Water management
Zajíček, Michal ; Vrána, Michal (referee) ; Baxant, Petr (advisor)
In the bachelor's thesis Connection of Solar Power Plant and Water management the author designs the technical solution of pump control using solar energy. The main reason is to make an automatic system for pumping the rainwater through filters due to increasing its quality. Powering the device with a solar power plant will reduce the energy requirements and will also make it possible to store surplus energy from the solar power plant into the potential energy of the water. The result of the work is the compact device with an automatic control system designed to control small 12 V pumps, theoretical design of the photovoltaic power plant to power the device and theoretical analysis of solar energy and water management issues.
Construction of small steam engine for the use of solar energy
Strava, Jan ; Šnajdárek, Ladislav (referee) ; Škorpík, Jiří (advisor)
Possible modern application of piston steam engine is electricity production using steam made by solar energy. This diploma thesis focuses on designing such piston steam engine Described solution would be effective as an off grid electricity generator, because alternative source of steam could be added for occasions, when sunlight is not powerfull enough for steam production.
Design of Parking Meter
Csadiová, Dominika ; Sládek, Josef (referee) ; Rubínová, Dana (advisor)
The bachelor thesis is focused on the design of a parking meter. The work contains an analysis of current products and the design of a new product based on the information obtained. The design meets the ČSN EN 12414 standard. The parking meter emphasizes ergonomics, integrates lighting and new solar panel technologies.
Design of a photovoltaic system with battery storage for a company
Šmatlo, Filip ; Maule, Petr (referee) ; Vaněk, Jiří (advisor)
The bachelor thesis is focused on design of the photovoltaic system for the company. The first part describes electricity production from the sun. There are described technologies of production of photovoltaic cells and technology of individual component of photovoltaic system. Furthermore, the concepts of photovoltaic systems and types of connections of these systems to the distribution network are described. Also the Czech legislation, recycling and safety in the field of photovoltaics are described. In the practical part of the thesis is created photovoltaic power station located on the roof of the building. Results of simulation of photovoltaic system created in PVSOL design program are described.
Energy performance of kindergarten
Mahovská, Adriana ; Vyhlídalová, Karolína (referee) ; Horák, Petr (advisor)
The bachelor’s thesis elaborates two energy performance certificates of kindergarten in the variant for the current status and the new state. The theoretical part deals with solar collectors. Computational part contains specification of building structures and power systems. It always includes a comparison of the default and the new state. The economic assessment is determined by the return on investment in revitalization. As part of the mandatory analysis of alternative sources, a proposal for a solar system for partial hot water heating will be established. The project part contains two processed EPCs (building energy performance certificate) for this building.
Effective Technologies for Heating
Čapoš, Eduard ; Špiláček, Michal (referee) ; Lisý, Martin (advisor)
The aim of this bachelor thesis is to summarize knowledge about current methods of heating family houses with it’s main focus on description and comparison. Second part of this thesis compares chosen methods applied on the model house.
Design of Hybrid Photovoltaic Inverter
Makarova, Anastasia ; Křenek, Ladislav (referee) ; Sovják, Richard (advisor)
Bachelor thesis resolve a design of 3 phase hybrid photovoltaic inverter. The work includes design and technical analysis of the current market. The final product solution meets the technical and ergonomic requirements and keeps the originally appearance. The device is designed for use indoor and outdoor.
Energy balance of landscape surface in forested and agricultural catchment
This diploma thesis deals with the statistical evaluation of the energy balance of landscape surface and its other chosen specifications via remote sensing and ground meteorological features. The thesis also includes the mapping of the landscape cover and its influence on the microclimate in the given area. The Novohradské Mountains, specifically the catchment of Bedřichovsky creek became the model area for this type of research. As each group of Land Cover (forest, permanent of grass cover, arable land, buildings) appears right in the catchment of Bedřichovský potok, it is suitable to evaluate the energy balance right in there.
