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.

Air-cooled condenser
Kloda, Michal ; Jaroslav, Sinecký (referee) ; Pospíšil, Jiří (advisor)
The Master’s thesis dealing with air-cooled condensers is split into four sections. The first section shows an overview of air cooling, introduction into air-cooled condensers of A-frame shape and finned tubes. The second section deals with heat transfer on the steam side and deals with trapped incondensables on the steam side of ACC. The third section deals with heat transfer on the air side, shows a brief overview of fans and selected problems on the air side. In the last section the simplified thedmodynamic calculation of air-cooled condenser is shown.

Polyfunctional building
Michna, Patrik ; Pospíšil, Jaroslav (referee) ; Fuciman, Ondřej (advisor)
The assignment of my diploma thesis was to design a polyfunctional building. Function of the building is based on the requirements of the Land Use Plan Brno, cadastral zone Židenice. The aim of the design was to improve the quality of public space in the area by creating parks, urban parterre with services, parking and by bringing missing features to the area. The building is located in the centre of the plot. The main facade is oriented to the main street. Design creates new parking on the ground and in the underground garage. On the first floor are rentable spaces for commerce and services. At 2nd and 3rd floor are open space offices with the possibility of spatial variability solutions. Architectural expression of the building is simple, consisting as a compact mass with parterre subsided, useful in terms of energetical sustainability. The facade of the building is made as a combination of a transparent double skin facade and opaque ventilated facade with fibre cement panels. Structural system is a precast concrete frame with a cast-in-place reinforced concrete shear core. Foundation is made as a reinforced concrete pads and strips. Ceiling is made of a precast prestressed hollow core slabs.

Thermionic generators
Primes, Alois ; Pospíšil, Jiří (referee) ; Brázdil, Marian (advisor)
This bachelor thesis deals with thermionic generators. In the first part of the thesis thermionic conversion principle and related physical phenomena are described. In the next part, the distribution of thermionic generators according to the construction is presented. The performed research shows that currently vacuum thermionic generators are being tested. This is followed by an overview of selected thermionic generators, and the purpose for which they were designed and the results achieved. It has been found that electric heating was used for experimental purposes, which can artificially increase the efficiency of the tested devices. The conclusion is dedicated to the performance and efficiency of thermionic devices and their possible use in the near future. It can be assumed that some types of thermionic generators will be used in power plants using high-temperature heat sources to increase their efficiency.

Draft mix for network independence
Horváth, Radovan ; Špiláček, Michal (referee) ; Pospíšil, Jiří (advisor)
The aim of this diploma thesis is the development of research on the topic of the draft mix for network independence. Next is the outline the various design solutions of the battery systems for accumulation electric energy and balance model energy supply system for the selected object. The practical part of diploma thesis deals with necessary resources and the size of batteries for autonomous operation during the summer months and also implements technical and economic studies aimed at finding cost-effective solutions. The work is divided into 6 chapters that contain 16 tables and 18 figures. Diploma thesis brings an option to configure a photovoltaic system and also describes the features, functions and the choice between the most used technologies. Evaluation of results of theoretical methods are described in the final part.

Power to gas system
Urbánek, Štěpán ; Baláš, Marek (referee) ; Pospíšil, Jiří (advisor)
This bachelor thesis deals with Power to Gas system and its subcomponents. The first part of this thesis is research of the Power to Gas subcomponents. In the second part a balance model of the Power to Gas system is developed based on the traced technical parameters from the first part. The third part deals with traceable implementations of the Power to Gas system and the last part is the design of the system for home implementation.

Natural gas
Trávníček, Zdeněk ; Moskalík, Jiří (referee) ; Pospíšil, Jiří (advisor)
The aim of the bachelor thesis is to collect facts about natural gas, focusing mainly on the situation in the Czech Republic. Firstly, the thesis discusses the natural gas in general - its properties, world resources, ways of production and usage. The main part of the thesis deals with supply and accumulation of natural gas in the Czech Republic. Secondly, enumeration and brief description of possibilities of natural gas substitution is presented. Finally, comparison of usage of classic non-condensing and condensing boiler for a family house heating is introduced. Recommendation of boiler type based on the model example is included as well.

Separation of water drops from jet of steam
Miček, Michal ; Baláš, Marek (referee) ; Pospíšil, Jiří (advisor)
This thesis is focused on separation water drops from jet of steam. Liested are some of basic principles of separation of moisture and particles, as well as equipment, which are using these principles. Furthemore, this thesis include the part devoted to water drop formation during condesation of vapor. Last part is focused on the design of cyclone separator.

Lighthouse for maritime communication
Chadima, Jan ; Mašek, Pavel (referee) ; Pospíšil, Jan (advisor)
This bachelor thesis deals with design and construction of lighthouse model, which will be used for teachning. It describes types of naval signalizacion, which are established by organization IALE in decree E-110. In thesis is described Arduino platform, metods of 3D printing and used materials For model needs was designed printed circuit board with microcontroller ATmega328P, which control RGB LED. Program, which control model, was writed on Arduino platform. Program has nine modes of sea light comunication. It can change periode, color of LED, brightness and turning on power saving mode. The result of this work is a functional model of lighthouse powerd by battery. Model is based on Green Cape Lighthouse in Australia in scale 1:58.
