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.

Design of a heating system for an office building
Vítek, Lukáš ; Horká, Lucie (referee) ; Vyhlídalová, Karolína (advisor)
The aim of this bachelor thesis is to design a proposal of space heating and water heating system for an administrative building in Ostrava. The building has four above-ground floors and an underground floor. In the underground floor are located technical building background, stocks and a parking. In the above-ground floors are administrative offices. The heating is solved as a water heating, with a distribution of the heat into the space using panel radiators and convectors. Water heating is solved by an accumulation heater. As a heating energy source serves a cascade gas boilers. We can find in the whole building a forced ventilation. The theoretical part of this thesis deals with the BIM technology.

Heat exchanger for waste heat utilization
Švach, Šimon ; Brázdil, Marian (referee) ; Špiláček, Michal (advisor)
This bachelor thesis deals with waste heat recovery using a heat exchanger. The aim of the thesis was to design a heat exchanger for the recovery of hot water from the cooling of a concentrator photovoltaic panel. The thesis is divided into theoretical and practical parts. In the theoretical part, a literature research on heat recovery and photovoltaics was carried out. In the practical part, a heat exchanger has been designed for a specific solution.

The Sanitary Instalation and Gas Instalation in Retirement Home
Minář, Lukáš ; Vrána, Jakub (referee) ; Wierzbická, Helena (advisor)
The scope of the thesis is the design of sanitation installations in the boarding house for seniors. The building has four floors above ground. It will be covered by gable roof. On the first floor, technical background of the building, reception and gym can be found. On the second floor, there is a kitchen and large dining room with terrace. The remaining floors are used for accommodation. Theoretical part focuses on brief history of using natural gas. Computational and project part deals with sewer system, plumbing and gas main in the building.

With wall heating systems
Bendová, Martina ; Topič, Jan (referee) ; Počinková, Marcela (advisor)
This work deals with the topic "Systems with wall heating". On this theme is elaborated theoretical part. Further experimental part, which deals with the measurement of wall heating and comparing the results with the software CalA. Subsequently, this topic is applied to the specified building in which the wall heating, among other things dealt with. The project addresses the design of central heating, water heating, water heater design power units and air tempering lawn for future newly built free-standing facilities football club. The project is designed in two versions. In the first variant of the heat source heat pumps air-water. In the second variant is the heat source hot water pipe which is connected to transfer water-water station with plate heat exchangers.

Measuring and regulation of computer controlled solar systems: Vizualization of energetic systems
Vlčnovská Kotlíková, Silvie ; Mašek, Ivan (referee) ; Půčková, Helena (advisor)
This work is oriented on study and evaluation of performance of real operating solar system. There was made analysis of actual technological unit and there was suggested mode of measuring of nodal parameters. There was made interconnection between the head operating unit of the solar system and the web server. And there was prepared software for grafical image of time and temperature dependence and for data transfer to ready web application. It primarily talks about increase of efficiency of real technological unit through regulating of parameter that is using up of accumulated energy.

Sanitation installations in residential building
Honzírek, Stanislav ; Vaščáková, Alena (referee) ; Vrána, Jakub (advisor)
This diploma thesis deals with sanitation installations in residential building in Brno. The theoretical part is devoted to the analysis of the topic with emphasis on Individual ways of preparation hot water in residential buildings. Technical part then solves the sanitation instalations of this building in the selected variation. Calculation part contains design and proportions of sewerage and rainwater system, internal water installations and their connection to present technical networks. I tis a multi-story building with two underground floors used for parking and five floors designed for housing. Project was done according to current Czech and Europe standarts and regulations.

Use of renewable resources for a multifunctional house
Andrš, Matěj ; Počinková, Marcela (referee) ; Formánek, Marian (advisor)
Master thesis deals with the design of a new multifunctional building. The theoretical part introduces heat sources, discussing their basic properties and types. The computational part describes a specific heating system design for the extended building permit and the design of individual components in the heating system. A ground/watter source heat pump is proposed as the heat source, with heat extracted from the ground through deep wells. The building will be heated using underfloor heating. The technical report then outlines the requirements and technical specifications. The project documentation is provided in the attachments. The experimental part of master thesis focuses on the operation of an air/water heat pump, aiming to investigate how the heat pump performs in relation to outdoor temperatures compared to supply temperatures. The operating times of individual parts of the heat pump were then evaluated. This section includes graphs and the results obtained.

Heating Asylum House
Gongolová, Klára ; Topič, Jan (referee) ; Počinková, Marcela (advisor)
In my thesis, i prepare proposals for heating and hot water in a shelter in the Havirov city. It is a renovated brick building that has two floors. The property also adjacent kitchen with workshop. In the calculation deals with the proposal of heating surfaces, plumbing, heating water and heat. I object to proposed plate radiators and pipe. Distribution of hot-water, two-pipe, symmetrical. I opted for the joint preparation of heating water for the production of domestic hot water heating and water heating. The heat source is a cascade of two heat pumps. In the theoretical part I focus on heat pumps.
