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.
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.
Energy performance of low-energy houses
Strava, Jan ; Štelcl, Otakar (referee) ; Baláš, Marek (advisor)
The bachelor´s thesis focuses on low-energy houses. It will prove wheter or not a house built as low-energy house really does meet requirements for this classification. Further it suggest investment options for additional reduction of energy consumption. The actual results of 10 year old building will be compared with investor´s original requests.
Power supply of remote object
Ocásek, Adam ; Štelcl, Otakar (referee) ; Fiedler, Jan (advisor)
This bachelor thesis is concerned with the issue of covering energy demands of an object which has not yet been electrified. It approaches the topic from both the side of possible technological solutions and the side of financial aspects of executing these projects and concludes with their analysis and comparison. The chosen solutions are the diesel generator, electric cable connection and photovoltaic panels.
Boilers for solid fuel
Hotový, Michal ; Štelcl, Otakar (referee) ; Baláš, Marek (advisor)
The task of this bachelor thesis is write up a research about solid fuel boilers and describe solid fuels. In second part of bachelor thesis I make an experiment. I measure an emission and efficient burning wood and coal.
The heating system with accumulation
Bártů, Marek ; Moskalík, Jiří (referee) ; Štelcl, Otakar (advisor)
Bachelor's thesis "The heating system with accumulation" is concerning with an appropriate solution of heating of a house. The thesis is divided into two main parts. The first part is dedicated to theoretical introduction that clarifies the issue of accumulation tank and describes how it works and what kind of processes takes place here. The second, practical part is devoted to calculation of losses and design of heating system in combination with the accumulation medium. As a model example is taken a house in Brno - Židenice.
Alternative Energy Resources for Family House
Buráň, Petr ; Štelcl, Otakar (referee) ; Špiláček, Michal (advisor)
In this bachelor thesis we will focus on alternative energy resources for family house. The thesis consists of two main chapters. The first chapter is focused on research, in which we will sequentially introduce different resource of energy and describe their principle of operation. In the second chapter we will create proposal designs for different energy resources for family house and their price comparisons.
Appliances for solid fuel for heating
Lackovič, Roman ; Hrnčířová, Michaela (referee) ; Štelcl, Otakar (advisor)
Bachelor's thesis "Appliances for solid fuel for heating" aims on the issue of emission measurement for solid fuel boilers. The first part is a theoretical introduction, where solid fuels are described, following are the types of appliances, which are powered by solid fuels. There are described legislation related to emission limits and principles of devices used for measururing emissions of solid fuel appliances at the end of the theoretical part. The second part is the attention devoted to description of measurement, that we have done, calculation of efficiency and emissions for measurement. Lastly, there is specified emission class to which the boiler, according to measurement, belongs.
Proposal heating system of the house
Taclík, Jakub ; Štelcl, Otakar (referee) ; Baláš, Marek (advisor)
This thesis is focused on computation of family house heat losses with two floors above ground, choice of three heat sources, and designing of radiators to cover the losses. The thesis also contains computation of a fuel consumption for a heating period and a discussion which one of heat sources, with particular temperature gradient, is the most economic.
Biomass boilers
Štěrba, Vítězslav ; Štelcl, Otakar (referee) ; Baláš, Marek (advisor)
This bachelor’s thesis deals with biomass boilers. The first part is dedicated to the biomass, its distribution, characteristics, potential and the possibility of energy recovery. The second part describes domestic market with biomass boilers low power for heating buildings and their functions. The last part deals economic comparison of selected boilers.
