Heating and cooling systems in a multifunctional building
Fuksa, Lukáš ; Horák, Petr (referee) ; Formánek, Marian (advisor)
The master´s thesis is about the design of heating and cooling of a multifunctional house. The building is functionally divided into parts of shops, administration and apartments. Thesis describes various cooling options and basic types and functions of air conditioning systems. Three variants of the system at the level for expanded building permits and their evaluation are developed. The selected variant is developed at the project level for the construction.
Pressure losses in heating systems
Švanda, Martin ; Horká, Lucie (referee) ; Počinková, Marcela (advisor)
This diploma thesis deals with pressure losses in heating systems. The diploma thesis is divided into three sections. The first part is theoretical and deals with the occurrence of pressure losses. It discusses the properties of the fluid that affect pressure losses. It also deals with hydrodynamic phenomena, flow distribution, pressure loss distribution and its calculations. The aim of the second part, which is practical, was to create a heating project for a selected object. The object is a two-floor kindergarten building located in Velké Němčice. For this project, two heating variants were created. For the first variant, radiators and heating benches were designed and for the second variant, underfloor heating was installed in the building. The goal was to use a source which will gain heat mainly from renewable sources, so the air / water heat pump was chosen as the source of heat production. The project ends with a technical report. The third part of the thesis is dedicated to an experiment which purpose was to find out how the pressure losses of the connecting pieces are reacting to the change with the change of the heating water conditions (flow, temperature). Alongside, two pipes were created which differed in the type of connecting pieces so it allowed to compare how their pressure losses differ. Both pipes were connected by radial pressing, but the fittings differed in the quality of the brass, and therefore in the construction. Also, part of the experimental section of the diploma thesis is a description of the course of radial pressing of fittings from the Herz company.
Determination of closing valve control moments
Benda, David ; Vosynek, Petr (referee) ; Hnízdil, Milan (advisor)
This bachelor thesis deals with the calculation of the torque on the output shaft of the four-concentric butterfly valves and experimental measurement of this torque on real manufactured valves. At the beginning is carried out a brief research, the purpose describe the basic components of the butterfly valves, its production variants of the offset disc, eventually types of fittings to piping. The main part describes the partial torque occurring on the individual components. Following data from the performer measurement and at the end are compared obtained results.
Vehicle Hydropneumatic Unit
Koudelka, Roman ; Hejtmánek, Petr (referee) ; Blaťák, Ondřej (advisor)
This diploma thesis, following the bachelor's thesis, is devoted to the gas-liquid unit of a vehicle, as the central element of hydropneumatic suspension. The aim is to dimension and construct this component and integrate it together with other elements into a complex suspension system. Based on possible forms listed in the research section, regarding to current development trends, the form of the unit is chosen. The practical part begins with simulations comparing a hydropneumatic with a conventional suspension system. After solving this issue, it is possible to proceed to the dimensioning of the basic parameters of the unit and then to its construction, respecting the relevant strength calculations. The last step is to build a conceptual design of the whole hydropneumatic suspension system.
Sanitary technical installations and gas pipeline in the apartment house
Polách, Petr ; Wierzbická, Helena (referee) ; Vaščáková, Alena (advisor)
The bachelor's thesis deals with the design of sanitary technical installations and a gas installations in an apartment house and with their connection to existing engineering networks. It also includes a design of a wastewater pumping facility to protect the underground rooms from the sewage flooding. It also includes a proposal for a light liquid separator, infiltration device and rainwater tank. The theoretical part is focused on gas main, fittings in gas distribution, gas pressure regulator and gas meters. Calculation and project part solves distribution of sewerage, water supply and gas pipeline in the specified object. It is a basement building with three aboveground floors and usable attic. On the ground floor of the apartment house there is a café.
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.
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.
Experimental validation of active flow control concept for automotive applications
Sobotka, Vojtěch ; Jebáček, Ivo (referee) ; Popela, Robert (advisor)
Tato diplomová práce obsahuje komplexní návrh systému aktivního řízení proudu instalovaného na osobním voze Škoda Roomster. Tato práce navazuje na výzkum provedený VUT a TUB na vozidle Volkswagen UP! Návrh lze rozdělit na tři základní části - návrh spoileru, návrh závěsů a návrh vyfukovacího systému. V každé z těchto částí je návrh detailně popsán a potřebná výkresová dokumentace je součástí práce v její příloze. Pro potřeby návrhu vyfukovacího systému bylo provedeno jeho testování. Výsledky testu jsou v této části uvedeny. Práce také obsahuje komplexní popis sestavení celého systému a jeho instalace na automobil.
Reconstruction of overhead power lines 110 kV
Krejčí, Tomáš ; Vašíček, Martin (referee) ; Lázničková, Ilona (advisor)
The master’s thesis deals with the topic new isolation lines of 110 kV. The aim is to propose new insulator hangers. The first, theoretical part focuses on the development of insulators, cutting and possibilities of application. They are the different materials that are used for the production of insulators HV, advantages and disadvantages long rod and cap and pin insulators. There are also described insulator hangers. The theoretical work is to describe thefittings for overhead transmission lines, which are, used to construct a insulator hanger. The last part of the theoretical work is intended distribution towers for overhead lines HV. The practical part deals with the design of new insulator suspensions for specific lines of 110 kV. The results are drawings newly designed hangers and a list of materials (fittings) for individual towers and the total amount of material. The practical part is calculating the differences in the conductor sag using old and new insulators hangers.
