Analysis and optimalization of pneumatic system of race pneumobile
Navrátil, Lukáš ; Nevrlý, Josef (referee) ; Ranuša, Matúš (advisor)
This thesis deals with the theoretical design of the new pneumatic system, which should lead to increased performance and fuel racing pneumobilu Blowfish. After the theoretical proposal deals with the analysis of both the new pneumatic circuit, and the old pneumatic circuit. The culmination of this work will be participating in the competition with the pneumobil in Hungary, Eger. The first part describes the current state pneumobilu contest and its rules. Further there are described in detail pneumatic elements that are used to pneumobilu. In the second part contains measurements that verify the effectiveness of the new pneumatic circuit.

Development of pressure switch for rail vehicles
Havelka, Ondřej ; Tůma, Jiří (referee) ; Tůma, Zdeněk (advisor)
This diploma thesis deals with the design of pneumatic pressure switch with adjustable hysteresis. In the thesis is carried out the introduction in the theory of compressed air and research of the pressure switches at the market. Based on the gathered information and customer specification, the design draft of the pressure switch has been created. In the thesis are described three main parts of the prototype: transform of the pressure, adjustable hysteresis and synchronization of the microswitches. In the end of the thesis is described the testing of prototype and summary of the results.

Use Compressed Air to Electric Power Accumulation
Martinák, Rostislav ; Radil, Lukáš (referee) ; Baxant, Petr (advisor)
The aim of this paper is to acquaint the reader with the possibilities of using the energy of compressed air in different areas, but particularly with the use of compressed air to accumulate electrical power. This paper introduces the technologies they use to their function pneumatic tools, compressed air car and compressed air energy storage facilities. The next section is to compare the compressed air energy storage systems with some accumulation possible ways of electrical power. The conclusion sums up work opportunities to accumulate electrical energy in compressed air.

Production of compressed air in the TZ Trinec
Kohut, Vojtěch ; Martinec, Jiří (referee) ; Fiedler, Jan (advisor)
The main purpose of this master’s thesis is description of the current technology of compressed air production in the grounds of Třinecké Železárny, a.s. (TZ). Compressed air for companies in the TZ area is manufactured and distributed by company Energetika Třinec, a.s. (ET). The part of the thesis is the preparation and execution of measurement including evaluation of specific energy consumption for production of compressed air by compressors of ET company. In conclusion there is proposed the possibility of substitution of compressors including the economic evaluation.

The Study of the Operating Production Management
Šolc, Jakub ; Kudlík, Jan (referee) ; Jurová, Marie (advisor)
The subject of master’s thesis "The study of the operating production management” is to rationalize production and distribution of compressed air. The thesis deals with the description of the current state, the analysis of compressed air production and the proposal for rationalization. The basis of this work is to implement lean manufacturing method in the company DI Industrial. The proposed steps are primarily designed for implementation in this firm but their principles and methods could be used in any company that uses compressed air technology. The study includes theoretical knowledge in the range of Lean manufacturing, Six Sigma tools and a pneumatics.

Accumulation of Energy from Renewable Energy Sources
Heller, Ondřej ; Radil, Lukáš (referee) ; Mastný, Petr (advisor)
The objective of the first part of master’s thesis is mapping the potential of various types of renewable sources in Europe and Czech Republic, especially solar energy, wind energy, water energy and biomass. There are described principals and ways of energy generation from these sources, brief overview of current technologies, and also their advantages and limitations. An important part is electric supply continuity from renewable sources, there are large differences and the resulting to restrictions on construction and connecting the units to the power system. In this work there are mentioned some impacts on network and rates of change of supply, some sources are also evaluated in terms of maximum power, that can be connected to the power system in our country. The conclusion of the first part is dedicated to energy storage technologies, which are suitable and usable for renewable sources, there are described their principals, properties, status of development and types of aplications, in which these technologies are used. This chapter also focusses on the price level of each technology. The second part of the thesis deals with 1 MWp on-grid photovoltaic power plant design. This design includes also the redox flow batteries accumulation, the first variant calculates on 24-hour steady energy supply, the second optimalized variant calculates on daily energy supply. There are the accumulation system costs estimated and also the payback period for the both variants. Additionally there is also determined minimum penalization for cost-effective operation. The last part is dedicated to changes of impact on the local grid and changes of system impacts, after the accumulation system is installed.

Power Increasing in Combustion Engines
Ehrenberger, Pavel ; Svída, David (referee) ; Dundálek, Radim (advisor)
This thesis contains the summary of information that relates to the problematics of the increasing performance of combustion engines. It describes the familiar ways of supercharging, and assesses the positive and negative aspects of implementation. It also gives information about the constructional resolution, about the functions and technical specifications of turboblowers a compressors, and other posible ways of supercharging. This thesis is pointing out the characteristics of the motor that is designed this specific way and his usage in the working conditions.
