Calculation of heat losses of a building and a design of a convenient heating system
Popelka, Stanislav ; Walek, Agata (referee) ; Mikulka, Jan (advisor)
Tepelné ztráty objektu jsou určující faktor pro celkovou spotřebu energie na vytápění budov a jelikož se materiály na stavbu a izolaci budovy stále inovují, jsou jak tepelné ztráty, tak i otopné zdroje neustále aktuálním tématem. Tato semestrální práce stručně seznámí čtenáře s nejrozšířenějšími otopnými zdroji – topným kotlem a tepelným čerpadlem. Dále pak zhodnotí výhody a nevýhody výše zmíněných tepelných zdrojů.
Boilers for solid fuel
Zezulka, Patrik ; Kudela, Libor (referee) ; Baláš, Marek (advisor)
This bachelor thesis deals with the heating of houses with boilers for solid fuels. Thesis is divided into several parts. In the first part is dealt with most common solid fuels, their characteristics, composition and modifications for house heating. The second part is focused on solid fuel boilers, describes chosen boilers, their operation, their advantages and disadvantages. In the last part is economically assessed the suitability of selected solid fuel boilers for heating the model house.
Modernization of biomass heat plant.
Sedlák, Martin ; Fiedler, Jan (referee) ; Fiedler, Jan (referee) ; Skála, Zdeněk (advisor)
The thesis examines the suitability of a CHP project in Bystřice nad Pernštejnem, a small town in Vysočina region, Czech Republic, which is currently supplied by biomass central heating. It reviews situation and availability of renewable energy sources and opportunities for CHP both in the Czech Republic and in Europe, including the context of current global developments. The opening chapters are followed with the renewable energy project for Bystřice nad Pernštejnem itself. The current technology, availability of biomass fuel for a potential future project, and possible development of energy sources in the town are analysed. Three alternative solutions for the CHP plant are suggested, with proposal for the technology and economic analysis, and possible future steps of the town council are discussed.
Assessment of investment in heating house
Zdražil, Pavel ; Štelcl, Otakar (referee) ; Baláš, Marek (advisor)
The bachelor´s thesis deals with economic evaluation of investment in insulation and heating and resulting operation of boilers in a family house. The calculation of thermal design power, which is needed for heating, was made according to norm ČSN EN 12831 for the house in actual state without insulation. Further were suggested two options of insulations and modernization of windows, for reduction of heat loss. Then was calculated the thermal design power for the two new options, again according to norm ČSN EN 12831. Next were presented possibilities of heat sources. For the specified family house was chosen a gas boiler in classical and condensing implementation for all three variants of insulation. These all options have made six variants which were compared together and evaluated. In the conclusion were excluded four variants economically disadvantageous and was chosen one of the final two variants as the best suggestion for the specified family house.
Heat sources for industrial buildings
Vejnarová, Nikola ; Počinková, Marcela (referee) ; Formánek, Marian (advisor)
The thesis is focused on the design of the new heat source of the existing building. The first part deals with the heat sources and fuels used in the Czech Republic. The second part includes design of three variants of heat sources: gas boilers, cogeneration unit with the electric boilers and cogeneration unit with gas boilers. The individual variations are also evaluated in terms of user comfort, space requirements or economy of operation. The third part includes measurement and evaluation of internal environment of the dining hall.
Modern Trends of Heating of Family House
Dohnal, Jakub ; Suk, Ladislav (referee) ; Lisý, Martin (advisor)
This bachelor thesis deals with modern trends of heating of family house. At the beggining is indicated brief history and current sources for heating of family houses. After this is described a research of various technologies for heating with their advantages and disadvantages. The last part is given to comparison all methods of heating and overall evaluation.
Performance of the system for energy utilization from biomass
Koláček, Richard ; Máša, Vítězslav (referee) ; Pavlas, Martin (advisor)
This diploma thesis deals with the problems associated with acquisition of experimental data from technological unit for biomass combustion with nominal capacity of 1 MW, with regard to determination of thermal efficiency. In the introduction part, parameters of currently available biomass-based fuels as well as of those with large potential in the future are summarized. Further, a review in the field of biomass combustion technology is given. Biomass boilers are compared according to their technical parameters, function and benefits and drawbacks. In theoretical part methods for determination of thermal efficiency by direct method, indirect method and modified indirect method are described. Main parameters influencing resultant values of efficiency are included into the analysis. In final part an evaluation of real operational data from prototype unit combusting wooden chips is made. Recommendations for further experimental data gathering and their processing with the aim to evaluate thermal efficiency are suggested.
Effect of change of fuel at boilers efficiency
Hazucha, Jan ; Štelcl, Otakar (referee) ; Baláš, Marek (advisor)
Bachelor‘s thesis deals with sorting solid fuels and boilers for solid fuels up to power of 200 kW, it’s most important attributes and legistative claims. Next part of the thesis deals with the impact between of different types of fuels on efficiency.
From a Dumb Boiler to a Smart One Using a Smart Socket
Mitura, Jacek ; Zemčík, Pavel (referee) ; Materna, Zdeněk (advisor)
Nowadays, the world of smart devices is growing very fast. Nevertheless, it remains difficult to acquire smart device for water heating applications. The usual reasons complicating this fact include the lack of the possibility of connection to the central control unit, or the need to replace the entire boiler with a new smart model. In both cases, the additional disadvantage is the higher price of such a solution. Therefore, the aim of this bachelor's thesis is to create a comprehensive and affordable solution, ensuring the conversion of an existing boiler to smart using a smart socket and a central server controlling the household. The solution uses a daily consumption forecast based on an exponential moving average to save electricity.
Proposal heat sources for home heating
Dobai, Szabolcs ; Poláčik, Ján (referee) ; Baláš, Marek (advisor)
This bachelor’s thesis deals with heating and selection of appropriate heat sources for family houses. The first chapter describes heat sources used for heating by type of fuel. The second part is devoted to calculation of the energy balance and the amount of heat required for a particular object. According to the results, five possible options are selected. At the end, the economic evaluation of the selected heat sources are processed and the most suitable one is selected. The attachment provides floor plan, section, list of the elements (windows and front door) and also appearance of the house.
