Increased power microturbines operating in indirect circulation
Polák, Luboš ; Fiedler, Jan (referee) ; Škorpík, Jiří (advisor)
Turbogenerator unit 100B TGU, produced in the First Brno Engineering Velká Bíteš a.s., works in Brayton indirect circulation. The aim of this work is the proposal to increase performance levels of technological unit in which the micro-turbine is applied. The work presents various ways to increase performance and efficiency of circulation. The possible options are compared with each of the technological and economic terms. Based on these criteria was selected variant feeding additional water into the circulation. For this design was the work of a mathematical model based on, which was established as the economic balance of the selected variants. The thesis also proposes a technological scheme, which is already incorporated the selected variant and an outline of the verification tests.

Fuid bed boiler for biomass
Bytešník, Jan ; Skála, Zdeněk (advisor)
This master thesis designes the calculation of fluid boiler with specific part - the circular fluid bed. The heat is given by combustion of wood biomass. The thesis is devided into several parts. All necessary elementary results are going to be reached within these parts: an analysis of solid fuel, stechiometry calculation, discussion on output limits and the environmental point of view, definition of elemental heat losses and general heat efficiency, calculation and design of a combustion part and its heat loads and calculation of enthalpies with different ash concentrations. All these phases get to a successful design of the fluid boiler heat balance and sizes of heat-flow surfaces. The composition of the boiler shows the added drawing.

Energy and environmental assessment of buildings
Kubínek, Tomáš ; Baroň, Alexandr (referee) ; Hirš, Jiří (advisor)
The aim of this thesis is to give a general idea of energy; what it is, how it is created (rather transformed), how it is distributed and used in many of its forms. In detail it describes how buildings are evaluated in terms of energy consumption, how can we lower this consumption and how it affects the environment. Part A, theory, gives a general idea of the theory surounding transformations, losses and uses of energy. It describes processes of assessment of buildings. Part B, calculation methods, give an idea how current CZ/EU regulations describe optimal calculation methods. These methods include: energetic, enviromental and economic evaluation of buildings or energy-saving measures. Part C, project, describes an exact measuring in Elementary School Svážná-Brno. It describes the means of obtaining information. Includes graphically processed monthly energy consumptions. It also includes list of used sensors (measuring air temperature, humidity and surface temperatures), schemes of sensors placements, schemes of building and technical systems. The main part of this project are graphs of measured data made in EXCEL with descriptions.

Airconditioning of intensive care unit
Cakl, Dominik ; Blasinski, Petr (referee) ; Rubina, Aleš (advisor)
This bachelor´s thesis deals with design of air-conditioning and air-condition systems in the spaces of intensive care unit of infection department and employees department. Proposoal of the systems meets relevant standarts, hygiene and operating requirements. The computational part is focused on total object analysis, heat balance, air flow in relation to increased hygiene requirements and requirements for air heating. The computational part also involves distribution, adjustment of air and other proposals, which are integrated in correctly proposed equipment. The theoretical part is involving heat recovery with heat pump. The project is processed on the level of the project implementing.

Condensing Steam Turbine
Šrůtek, Petr ; Krbek, Jaroslav (referee) ; Fiedler, Jan (advisor)
The theme of master's thesis is the design of condensing steam turbine with three unregulated steam outputs. The steam parameters in individual outputs are dealt with in heat balance circulation. This chapter is followed by thermodynamic and strength calculations, including the calculation of the turbine gland steam and design of drainage. Structural design of the turbine is also included in this thesis.

Intensive care unit air conditioning
Dobrovolná, Natálie ; Uher, Pavel (referee) ; Rubina, Aleš (advisor)
The bachelor's thesis deals with the ventilation system serving hospital premises. The system is divided into two separate functional units. Facility No. 1 serves the ICU (Intensive Care Unit) department and its associated premises. Facility No. 2 serves the facilities of employees, doctors' rooms and associated premises. The design of the equipment meets the relevant standards, hygiene standards and operational requirements. The calculation part deals with the design of air conditioning in the ICU, it deals with the overall analysis of both functional units, heat gains, heat loss, air flows, pressure drops in both functional units and other proposals necessary for the design and proper operation of the air conditioning system. This part is also focused on the distribution and treatment of fresh air. The theoretical part deals with clean rooms, their definition and distribution of air supplied to these rooms. The theoretical part also deals with the installation of operating theaters, images of flow in these areas and their internal microclimate.

Thermal comfort analysis and energy assessment of a historic building
Kalný, Richard ; Horká, Lucie (referee) ; Weyr, Jan (advisor)
Objective of this thesis is presenting a comprehensive analysis of a climate inside a building, ways of obtaining and analysing weather data, measuring certain quantities inside the building and evaluating the energy efficiency of buildings. The experimental part deals with a historical building in Prague. Weather data and interior data logger readings are analysed to create a model in the BSim program, which is calibrated to a high degree of accuracy. Summer outcomes are discussed; the building meets regulatory requirements. In addition, an Energy Performance Certificate is issued. Structural and technical modifications are proposed in order to reduce solar heat gains, thus achieving an annual energy saving of 1671 kWh.

Air conditioning design in the theater
Vladyková, Pavlína ; Rubinová, Olga (referee) ; Blasinski, Petr (advisor)
The aim of the work is to design an air conditioning system for the auditorium and stage of the theatre that will cover the heat gains and partly the losses. The work is divided into three parts - theoretical, computational and design. The first part deals with the carbon dioxide concentration in the interior. The second part contains all the necessary calculations and design of the air conditioning system in the theatre. The third part is practical - it contains the technical report, technical specification, and control scheme. Drawings of the proposed air conditioning system are also part of this work. The procedure has been carried out in accordance with the applicable standards and guidelines

The computation of nuclear power plant heat exchanger
Fialová, Ludmila ; Baláš, Marek (referee) ; Milčák, Pavel (advisor)
The theoretical part of my thesis analyses the topic of heat exchangers in nuclear power plants. A summary of each nuclear power plant’s circuit and its main is conducted. Furthermore, the term heat exchanger is introduced. The function and elemental construction of some significant types of heat exchangers is analysed. Their function in nuclear power plants is also described. In the computational part of this thesis, values describing parameters of the heat exchange, the heat balance of the exchanger and its main construction dimensions are calculated for a particular heat exchanger – tube and shell condenser.
