Comparing invest to save heating
Kalivodová, Markéta ; Kracík, Petr (referee) ; Baláš, Marek (advisor)
The purpose of this bachelor thesis is to compare invest to save heating of a sample family house. At the beginning of the thesis there are analysed some individual options for reducing energy efficiency of the house. There are also discussed disadvantages of thermal insulation if it is badly performed. Thereafter there were calculated the heat losses of the house according to standard ČSN EN 12831, which determined the total annual energy demand for heating. These calculations were repeated in the software TechCON®, in which was later solved individual proposals to reduce the heat loss of the house. In the end, all options were evaluated.

Family Houses Heating by Heat Pump
Zeťák, Marek ; Kalivodová, Markéta (referee) ; Lisý, Martin (advisor)
Heat sources are a daily part of our lives. The increasing demands for efficient, low-cost and eco-friendly heating of a family home can be satisfied with a heat pump. The main benefits include eco-friendly, efficient and unattended operations with low operating cost. This bachelor thesis provides information on how the heat pump works, what types exist and explains the concepts associated with them. Due to the decreasing power at low temperature, heat pumps are often installed in a bivalent connection with an additional heat source. The heat pump, like any other device, undergoes constant upgrades to improve the parameters and its function. In the final part of the thesis, a basic economic study of a new heat source for a model house is carried out, where the heat pump is one of the proposed options.

Refuse Derived Fuel
Exnerová, Anežka ; Kalivodová, Markéta (referee) ; Lachman, Jakub (advisor)
This bachelor’s thesis deals with the Waste-to-Energy topic focusing on refuse derived fuels. The aim of the first part is to describe what refuse derived fuels are, what are their properties and composition. From this point of view, we determine a comparison with municipal solid waste. Second part is about production process. Possible parameters of refuse derived fuels and the technological process of mechanical-biological treatment are presented here. Following part is focused on fuel combustion. This chapter lists combustion plants and emissions from the incineration of waste and refuse derived fuel.

Steam turbine vacuum breaker
Kalivodová, Markéta ; Kracík, Petr (referee) ; Fiedler, Jan (advisor)
In this master’s thesis, a preliminary thermodynamic calculation of the turbine is made. Then, the design and location of the vacuum breaker is devised for this turbine. The aim of the master’s thesis is to calculate a time needed to break the vacuum, ie to determine how long it takes to reach the atmospheric pressure inside the turbine and add-on devices. To verify and improve the accuracy of the calculation there are data measured on real projects used.

Particle concentration measurement by various methods
Kuruc, Jan ; Kalivodová, Markéta (referee) ; Sitek, Tomáš (advisor)
In addition to the gaseous components, the Earth's atmosphere contains solid and liquid particles from various sources. These particles are monitored and examined mainly due to their environmental and health impacts and many methods are used for their monitoring and measurement. The aim of the research part of this thesis is to bring the topic of aerosol particles, namely their division, the methods of formation closer, to indicate the impact of these particles on the environment and human health, and to further describe the measuring instruments used to measure the concentration of fine particles. The practical part of this work is the measurement of particle concentration using the impactor, the monitoring of particle concentrations and other data measured by the Brno-Arboretum measuring station, as well as the subsequent evaluation of the measured and monitored data. The primary output from the almost 18-day impactor measurement is considered to be the total concentration of all captured particles of 11.56 g/Nm. The size distribution of the captured particles is plotted in the graph, as well as the quantities monitored from the station. The data obtained is compared at the end and the links linking these data are given.

Energy utilization of biomass through wet fermentation
Odehnal, Lukáš ; Linda, Jakub (referee) ; Kalivodová, Markéta (advisor)
The final thesis focuses on the energy utilization of biomass and the description and calculation of the energy balance of a specific biogas plant, Valeč near Hrotovice. The text is divided into five blocks, in the first block the sources of biomass and its subsequent energy use are discussed. The second part covers processes and technologies using wet fermentation. The third chapter describes a specific biogas plant. The fourth part calculates the balance of electricity and heat production, and the last chapter of the thesis summarizes the calculated values and compares the technology used with other possible sources.

Design of a heating system for a house
Peřina, Petr ; Kalivodová, Markéta (referee) ; Baláš, Marek (advisor)
This bachelor thesis deals with the proposal of a suitable heating system for a family house. The first part contains an overview of different methods of heating. The second part is focused on the calculation of heat losses and heat demand of a particular family house. In the third part, various heat sources are designed and compared for this object. At the end of the work, these proposals are evaluated and a suitable source, which would be advantageous to replace the existing one, is selected.
