Project of the photovoltaic system
Ševčíková, Kateřina ; Půčková, Helena (referee) ; Kotlík, Josef (advisor)
The diploma thesis deals with elaboration of project solar thermal and photovoltaic solar systems for all-season service. The theoretical part focuses on the general description of the solar thermal and photovoltaic systems, legislation of renewable sources in the Czech Republic and the status of photovoltaics in the Czech Republic. The experimental part deals with the design of measures for energy saving by using solar energy systems. These measures are proposed for construction of houses in Podolí u Brna, especially on extra-family house. The aim of the work is to make a proportioning, choosing the right parts and calculating the economic and ecologic balance. Finally, thesis gives recommendations for further action in saving energy in houses in Podolí u Brna.
Aspects of the disposal and recykling of photovoltaic panels in CR
Papírek, Jan ; Mikšík, František (referee) ; Kotlík, Josef (advisor)
This diploma thesis is focused on the assessment of the possibilities of disposal of photovoltaic panels installed in the Czech Republic. In addition to the basic theory of photovoltaic cells and panels, the theoretical parts describe legislation, subsidies in the field of photovoltaics and the development of photovoltaics in the Czech Republic. As part of recycling, their methods, work with the collective system, as well as the impact on the environment are analyzed. In the experimental part, using the data of the installed capacity and the average weights of the panels, various projections of the disposal of the panels over time are made, which take into account factors such as the life of the power plant or the capacity of the recycling line. Furthermore, according to the available literature, an analysis of the revenue from the sale of recycled materials contained in panels installed in our territory is performed. Subsequently, the needs of future implementers of proven estimates of labor and logical demands were assessed. Finally, an economic evaluation of the fundamental aspects of the FRELP recycling process was performed and the net prices of different recycling directions were determined.
Non - freezing heat transfer liquids on glycerol platform
Trombik, Tomasz ; Friedl, Zdeněk (referee) ; Kotlík, Josef (advisor)
This thesis is focused on proposition of non-freezing heat transfer fluid. Fluid will be based on mixture of propane-1,2,3-triol with water and modern corrosion inhibitors. Then will be investigate, if this new compound is competetive to common used liquids like ethylene glycol or propylene glycol.
Utilizable solar energy balance for preparation domestic hot water in family houses, area - South Moravia
Dobešová, Zuzana ; Půčková, Helena (referee) ; Kotlík, Josef (advisor)
This thesis deals with analyses of solar energy balance for hot water preparation in family houses Vacenovice and Vracov in the South Moravian Region. Analyses potential and real possibilities of this region and the South Moravian Region in cooperation with the Territorial energy conception of region development.
Fast-growing trees as a renewable energy source
Žvaková, Veronika ; Půčková, Helena (referee) ; Kotlík, Josef (advisor)
This bachelor thesis is focused on biomass as a renewable energy sources. The main topic is fast growing trees and their effects on biological diversity, the local ecosystem and landscape ecology. Literature survey was conducted regarding using this kind of biomass in the Czech Republic. Thesis reviews technological methods of cultivation and treatment of fast growing trees.
Changes anticorrosive system non - freezing heat transfer liquid
Pexa, Michal ; Mastný,, Petr (referee) ; Kotlík, Josef (advisor)
This diploma thesis is focused on proposition of non-freezing heat transfer fluid for solar systems. Fluid will be based on mixture of new available compound propane-1,3-diol with water and modern corrosion inhibitors. Then will be investigate, if this new compound is competetive to common used liquids like ethylene glycol or propylene glycol.
Water utilization in ZOO Brno
Hejsková Pekárková, Marie ; Vávrová, Milada (referee) ; Kotlík, Josef (advisor)
Study analyses contemporary condition of water distribution in ZOO Brno with respect to environmental defensibility of local flora and fauna. Networks and condition of single water mains has been charted. Possible ways of supplying ZOO with process water has been considered. In the second part study analyses water system, quality of water and its influence on animals kept in exposition Tropical kingdom and in pavilion of arctic wolf and american beaver.
Vegetable adaptogens - Schizandra chinensis
Pospíchalová, Lucie ; Půčková, Helena (referee) ; Kotlík, Josef (advisor)
This thesis deals with plant adaptogens (bioactive substances) in the plant Schisandra chinensis. The theoretical part is focused on characterization of the Schisandra genus, characterization of the Schisandra chinensis as a plant, its properties, occurrence and growing possibilities in the regional climate zone of the South Moravian Region as well as the use of this plant. Furthermore, adaptogens are described from a chemical point of view and their possible methods of isolation from individual parts of plants. The experimental part deals with extraction of fruits and leaves from plant Schisandra chinensis. Further, in the leaves extract was determined chlorophyll a, chlorophyll b and carotenoids by spectrophotometry, where the quantity of individual substances was confirmed for months April – May.
Water utilization in ZOO Brno
Jančurová, Hana ; Zlámalová Gargošová, Helena (referee) ; Kotlík, Josef (advisor)
The subject of this thesis is make analysis water system in the pavilion of reptiles in the Zoo Brno, with an emphasis on environmental sustainability, local fauna and flora. It is propose specific technical and technological resolutions to reduce the economic and energy performance of the pavilion. The design primarily needed to respect the needs of the animals, but also high aesthetic and educational function of the pavilion.
Adaptogens in the Shizandra chinensis plant
Pospíchalová, Lucie ; Půčková, Helena (referee) ; Kotlík, Josef (advisor)
This diploma thesis deals with plant adaptogens (bioactive substances) in the plant Schisandra chinensis. The theoretical part is focused on characterization of the Schisandra genus, characterization of the Schisandra chinensis as a plant, its properties, occurrence and growing possibilities in the climate zone. Furthermore, The effects of these adaptogens on the organism and the prediction of possible use in food supplements are described. The experimental part deals with the extraction of fruits and leaves from plant Schisandra chinensis. Further, chlorophyll a, chlorophyll b in the leaves extract was determined by UV – VIS spectrophotometry, whereby the optimal amount 3:1 of chlorophyll was confirmed for the plants growing in optimal conditions. Finally, the concentration of the adaptogen schisandrin A in the dried fruits was from different kind of extraction measured by HPLC. In all fruits, schisandrin A was confirmed, but the amount is different in each sample.
