Cooling systems for polyfunctional object.
Milatová, Adriána ; Blasinski, Petr (referee) ; Formánek, Marian (advisor)
The diploma thesis deals with the design of cooling devices of a fourteen-storey polyfunctional building with administration part and housing units. The thesis describes the physical nature of cooling, the basic types and functions of cooling systems and legislation related to cooling devices. Two types of cooling systems are selected and developed for the assigned object at the building permit design level. The work includes calculations of all elements of individual systems. The purpose of this diploma thesis is the comparison of these variants and the evaluation of suitability for use on the individual parts of the assigned building. The variant chosen is elaborated at the level of the rea-lization project, including the drawing documentation.

Dam Breach of Eartfill Dams Due to Internal Erosion
Kotaška, Stanislav ; Hodák, Jiří (referee) ; Satrapa, Ladislav (referee) ; Jandora, Jan (advisor)
Dam breaches are relatively rare but can be catastrophic. In the event of a earthfill dam breach, a special flood will occur that can cause loss of life and property. While it is difficult to prevent a earthfill dam breach, it is important to focus on protecting the population. Depending on the type of damage expected to the earthfill dam, different measures are taken to protect people. After analysing possible dam failures and calculating the consequences, risks are assessed and then reduced by relocating people and property. Accurate analysis of potential failures and prediction of the flood wave is necessary to predict how a given special flood will propagate in the floodplain below the dam. The thesis clearly summarises the mechanism of earthfill dam breach due to internal erosion and presents mathematical methods for modelling this phenomenon. The main result is an increase in the predictive capability of the AREBA software used to simulate breaches of earthfill dams due to internal erosion and overtopping. An extension to the AREBA software has been introduced to allow the setting of different levels of comparison plane, consumption curves and reservoir characteristics. In addition, the AREBA software has been extended to include water balance equation and additional methods for dealing with water levels below the dam. New methods have also been added to deal with roof collapse of the seepage pipe, friction losses in the seepage pipe and dealing with the roughness coefficient calculations. A Monte Carlo method with LHS sampling was introduced to generate the input parameters. After applying the proposed improvements, a sensitivity analysis was carried out to identify the most sensitive geotechnical model parameters. In addition, other software’s for simulating the failure of earthfill dams due to internal erosion was presented (EMBREA, DL Breach, WinDAM C) and its results were compared with the modified AREBA software on selected case studies.

Design of energetic unit pipeline
Adamec, Martin ; Gottvald, Jakub (referee) ; Nekvasil, Richard (advisor)
This diploma work is aimed at a proposal and an overall controll of the pipeline net. There is a preliminary calculation performed (by the analytical method) in this diploma work. There is also a comparison with the numerical computing to find out whether the pipe branch does or does not comply.

The small hydroelectric power station design
Kokeš, Petr ; Pěcha, Jiří (referee) ; Matoušek, Antonín (advisor)
The thesis deals with comprehensive design of the small hydroelectric power station in the particular site. There is the site description in the first part followed by evaluation of the hydroenergetic capacity of the watercourse and description of the inlet building and piping. Building and machinery part of the turbine hall is described in the next part. The electric part of the power station is worked up to wider scope and includes hydroalternator, switchgears incl. power for self-consumption, electric protections, cabling, transformer substation and high voltage inlet line. There is a description of the control system in the next part and economical evaluation of the investment is at the end.

Air-Conditioning in the hospital pavilion
Kops, Tomáš ; Blasinski, Petr (referee) ; Rubinová, Olga (advisor)
The aim of the bachelor thesis is to design and evaluate the air-conditioning system for the medical facility. The first and second above-ground floors are designed and designed to meet hygienic and operational conditions for medical facilities. The air-handling system provides fresh air into the interior, eliminating heat losses in the winter and heat gains in the summer.

Principles and design of project elaboration of boiler islands aimed at piping
Suchomel, Radoslav ; Létal, Tomáš (referee) ; Nekvasil, Richard (advisor)
The Thesis solves the issue of a design and construction of piping specifically focused on boiler apparatus and its equipment. This issue is important for creation of the piping classes in the (PDMS) programmes and for acceleration of output parameters which are mainly the temperature, materials, variable parameters, etc. This leads to other problems such as service life, security, economy, etc., are.

Elements reducing pressure in pipeline systems
Kohút, Jiří ; Kůrečka, Jan (referee) ; Himr, Daniel (advisor)
The aim of the bachelor thesis is to provide a comprehensive overview of control elements in piping systems. The fluid at different flow rates exhibits different behavior and due to the fluid contact with the pipeline, pressure losses occur. Elements in piping systems meet various requirements such as pressure control, flow rate control, barrier and flow direction control. The thesis deals with the categories description and functional priciples of individual elements. The practical part consists of the laboratory measurement describing characteristic of one of the pressure control elements, namely the pressure reducing valve. The measured characteristic is compared to characterstic from a company called Malgorani.

Types and principles of water reservoirs
Cakl, Vojtěch ; Fialová, Simona (referee) ; Pochylý, František (advisor)
The bachelor thesis deals with decription of the water reservoirs, in particular for the purposes of the irrigation. In the first part of the thesis is overview of the functions and distribution by purpose and location to the consumption. Following is the proposal of the storage tank volume by purpose. In next part there is a description of the construction, shape and equipment of the water reservoir. Subsenquently there is expalained the principle on simple arithmetical example. The last part of the bachelor thesis focussing of multifunctional water reservoirs and their functions in relation to the landscape. It contains some examples and proper scheme of multifunctional water reservoir.

Heating of cultural house with restaurant
Ratajský, Radek ; Vyhlídalová, Karolína (referee) ; Počinková, Marcela (advisor)
The topic of this thesis is the design of heating, mechanical ventilation and hot water production in a culture center with a restaurant – Sokolovna. The thesis is divided into three parts – theoretical, calculations and the project. The theoretical part is focused on solid fuel boilers and the related legislation. The heat transmission calculations, the design of heat source, heating elements, hot water production and distribution can be found in the calculations. The project contains drawings and the technical report.
