Media discourse on Green Deal from energy perspective
Kolářová, Marta
Green Deal, the European Commission's initiative to protect the climate and reduce emissions greenhouse gases, has sparked controversy in the Czech public debate. An analysis of media discourse on the Green Deal from an energy perspective shows that the Green Deal is perceived predominantly negatively. In the media, it has been labelled with condemnatory statements and negative characteristics, especially by leading Czech politicians. A more favourable view of it is held by Czech companies, municipalities and experts. The public debate is being transformed in particular by the impact of the war in Ukraine in favour of energy security and accelerating the green transformation.

Energy supply of the complex Technicka 2
Buráň, Petr ; Lisý, Martin (referee) ; Pospíšil, Jiří (advisor)
The theme of this master thesis is „Energy supply to the site Technická 2“. This thesis is divided into several parts. First we will get in touch with concept of combined heat and power and also with principle of photovoltaic electricity production. We will continue with description of site before and after reconstruction. Then we will follow with analyze the effect of reconstruction on energy consumption. In the end we will make some suggestions for using the local source of heat and electricity in Faculty of mechanical engineering, Brno university of technology. All suggestions will be analyzed from energy and economic point of view.

Heat storage in solar thermal systems
Mokriš, Lukáš ; Hejčík, Jiří (referee) ; Charvát, Pavel (advisor)
In this bachelor’s thesis are described methods of heat storage in solar thermal systems. Solar energy is retrieved in form of solar radiation, that is processed and stored in the form of sensible heat of solid materials and liquids, as heat of fusion of some material or as chemical heat, which is created during reversible chemical reactions.

Environmental design of the kindergarten building
Velísková, Jana ; Rubinová, Olga (referee) ; Uher, Pavel (advisor)
This thesis deals with the design of a kindergarten building in the village of Dolní Lhota.It is designed as a two-storey building with a flat roof. It will be connected to the existing primary school building. The first floor will be used for kindergarten purposes, the second floor will be used for afternoon activities. The first floor will house a classroom, toilets for children, cloakroom, offices, cleaning facilities, storage, utility room, mechanical room. On the second floor there are two classrooms for afternoon activities, a cloakroom, office, storage and toilets. It consists of three parts. The first part deals with the design of the building structure. It contains the project documentation with all floor plans, sections, foundations, roof drawing, technical report, views. The structural system of the building is a wall system. The perimeter and internal load-bearing masonry is designed in ceramic blocks. The ceilings are made of spiroll panels. The second part contains the technical equipment of the building. Design of the air handling unit and distribution elements to the rooms. Calculation of rainwater utilisation. It also includes the design of the building heating, lighting and a drawing of the global scheme. Photovoltaic panels are proposed on the roof to cover the building's consumption. Heating is provided by groundwater In the third part I discuss the effect of zoning a building. I used the design of air handling units as an example. Given the use of a school building, where the first floor will run mostly in the morning and the second in the afternoon, I looked at which option is more economical

Measuring and Control System for Heat Pump
Ščepka, Ondrej ; Morávek, Jan (referee) ; Mastný, Petr (advisor)
This master thesis describes the issue of the measuring and control system for the heat pump. In the first part of the thesis is described the principle of heat pump activity, its basic components. The second part contains the distribution of heat pumps according to the method of obtaining and transferring the heat. The following chapter contains the description of system status before the modernization. In the practical part of this thesis is the proposal and realization of new control and monitoring system including the description of individual components. In the conclusion of the thesis is a verification of the use of proposed control and monitoring system of heat pump for the measuring of its operational characteristics.

Energetic model of linear axis with ball screw and servodrive
Sládek, Vojtěch ; Tůma, Jiří (referee) ; Huzlík, Rostislav (advisor)
The aim of the thesis was to study the Energy Models of Linear Axes with Ball Screws and Servo Drives, to analyze the individual parts of the axis with respect to losses, the methodology of calculating the losses on the electrical part and the mechanical part of the drive and creating a complex algorithm that calculates the energy consumed for the specified motion. The thesis is divided into a theoretical and practical part, where the theoretical part is divided into the treatise on the electrical part of the axis and its losses and the part that deals with the mechanical part and its losses. The calculation is divided into the basic verification algorithm and the calculation on the given example. Each calculation is calculated for both linear acceleration and S-curve acceleration. For both types of acceleration, the result of energy and its course over time is also the waveforms of position, velocity, acceleration, angular acceleration, moments, powers, power, speed and currents over time.

The influence of decreasing of impeller diameter, change Q - Y characteristic
Hyriak, Maroš ; Habán, Vladimír (referee) ; Haluza, Miloslav (advisor)
The purpose of the thesis is to familiarize with the fundamental characteristics of ta centrifugal pump while changing geometry of the output section of its impeller trimming. Characteristics of a pump is calculated whilst diameter of the impeller is changed. More specifically, changes in the flow and energy are observed while diameter of the impeller is decreasing. Two possible solutions, approximate and accurate, are offered for both parameters. The thesis suggests that an application of the approximate solution is satisfactory for the flow calculation of the impeller. In contrast, for the energy calculation is the approximate solution sufficient only in case of the slight trimming. Increase in the trimming results in the drop of the hydraulic efficiency and decrease in the accuracy of the results. Consequently, the accurate solution is recommended for the energy calculations. Limitations of the paper may be represented by two facts. First, in comparison with the calculations, results are in reality affected my numerous variables that have not been included in the calculations due to their unpredictability. Second, calculations were based on the several assumptions that are rarely met in the reality. The results of the thesis are applicable in the every-day life when adapting the pump to the customer needs.
