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 the building using renewable energy sources
Švanda, Martin ; Vyhlídalová, Karolína (referee) ; Hirš, Jiří (advisor)
The aim of this bachelor’s thesis is design of heating and preparing of domestic hot water use of renewable energy sources. The building is a family house. The theoretical part deals with solar systems, solar collectors and their function. The calculating part deals with improvement thermal properties of structures, design heating system and preparing of domestic hot water. As a heat source was proposed condensing boiler. The hot water is ensured by solar collectors. In case of hot water shortage will be use heat exchanger situated in condensing boiler. Design documentation contains engineering report and drawings of heating.

The Business Plan of the Porterhouse BeerPub
Švanda, Martin ; Trlida, Martin (referee) ; Luňáček, Jiří (advisor)
The diploma thesis focuses on creating a real budiness plan for establishment a porter house, that will offer beer from production of small breweries. Part of the thesis is also a making of prediction models for sales and costs in the branch. It also contains a financial plan and evaluation of the investment effectivity.
