Heating residential building
Blažek, Tomáš ; Počinková, Marcela (referee) ; Horák, Petr (advisor)
The aim of this bachelor’s thesis are issues of condensing boilers in theoretical part. The computational part solves design of heating and hot water in residential building in Kyjov. The four-floor residential building is situated in slightly bulit-up area. It consists of 9 flats for 24 persons. The heat source for this building is a gas condensing boiler. The heating surface consist of steel panel radiators, tubular heaters and convectors.

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.

Heating of residential building
Ženožička, Filip ; Komínek, Petr (referee) ; Počinková, Marcela (advisor)
The subject of this thesis is the design of heating and hot water in the apartment building in Zlin on Jižní Svahy. The building has five floors above ground and one underground floor. There are designed two variants of heat source for heating and hot water (gas boiler and transfer stations). Part A solved heating water by the use of solar collectors. Part B deals with design of the heating system, hot water heating, insurance and facility expansion. The last part C forms a technical report and drawings heating in the building.

Heating using condensing technology
Jadrníčková, Kateřina ; Počinková, Marcela (referee) ; Horák, Petr (advisor)
The subject of this bachelor thesis is the design of heating and hot water preparation of an administrative building in the complex Svit in Zlín. The building has three above-ground floors. As a source of heat are designed gas condensing boilers here. In the theoretical part A is solved the problem of gas condensing boilers. The computational part B deals with the design of the heating system, the preparation of hot water and the safety, expansion and other equipment necessary for the design of central heating. The last part C consists of the technical report and the drawing documentation of the heating of the building.

Heating of the Multifunctional Building
Konečný, Ladislav ; Topič, Jan (referee) ; Vendlová, Lucie (advisor)
This diploma thesis proposes the heating system and ventilation in mixed-use building. The building is located in Uherské Hradiště. The object of this work is the selection of appropriate variants of two heat sources (gas boilers and solid fuel boiler). The project is focus on design of the heating system chosen mode of heating, which are gas boilers and the concept of forced ventilation. The theoretical part is focused on the regulation.

Heating of the kindergarten
Dužík, Vojtěch ; Horák, Petr (referee) ; Počinková, Marcela (advisor)
This thesis concerns the heating of the kindergarten. The heating system is designed as low-temperature with the main source of heat which is heat pump of a special type air-water in inner design. Heat pump is completed with parallel bivalent source, which is an electric heating element. There are designed panel radiators in whole edifice. Hot water is being prepared by DHW cylinder. The heating of hot water is being provided by thermal pump in combination with electric DHW cylinder. The exchange of air in the whole of edifice is provided by a system of forced ventilation with heat recovery. In theoretical part I focus on heat pumps.

Heating the building pedagogical-psychological services
Vlasák, Vojtěch ; Adam, Pavel (referee) ; Počinková, Marcela (advisor)
My bachelor’s thesis deals with a heating system designed for a four-storey building in which a pedagogical-psychological centre is based. The heating installation uses an air/water heat pump and a low-temperature forced water circulation system. For all storeys, the design proposes panel heaters, the only exception being one tubular radiator. As for ventilation, it is designed as a forced balanced ventilation system. Last but not least, the thesis includes a hot-water preparation system which also uses the heat pump.

Use of renewable energy sources for heating
Heneková, Barbara ; Počinková, Marcela (referee) ; Horák, Petr (advisor)
This work is solving the proposal of underfloor heating office building. The theoretical part focused on the characteristics of heat pumps.The computational part is making a proposal for underfloor heating. The warm source is a heat pump of air and water, located in the exterior. The work includes a proposal for the all needed equipement and also the design of the source of warm water.

PCM-based heat and cold storage
Němec, Lukáš ; Ostrý, Milan (referee) ; Šikula, Ondřej (advisor)
In the first part of the bachelor thesis I will deal with the accumulation of heat and cold using materials with phase change and also the design of a PCM storage tank. The aim of my effort is to design the most ideal spacing of tubes in a given tank, so as to achieve the greatest possible heat capacity. I performed simulation experiments in CalA 4.0. The second part is computational, where I focus on the design of heating in the pension. I solve heating with an air-to-water heat pump. I designed solar collectors for hot water heating. The last and third part is the project, which contains the project documentation together with the technical report.
