Analyses of the Compressed Air Energy Storage proces in Ansys Fluent system
Hájková, Věra ; Šabacká, Pavla (referee) ; Maxa, Jiří (advisor)
This bachelor thesis discusses different types of energy storage in the introduction. It describes the different technologies, their functions, advantages and disadvantages. It compares them on the basis of the ESOI ratio, which is the ratio of energy stored on invested. The main type of energy storage covered in the term paper is compressed air energy storage. The thesis describes the principle of a method of energy storage as well the companies and projects that are working on or using this technology. Furthermore, the issue of heat energy loss during air compression is outlined, which leads to a significant reduction in efficiency. The last part of the thesis is a practical part, which uses a model example to show the temperature and pressure evolution during the pumping of air into the storage tank.

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.

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.

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.

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.
