Use of residual heat
Vlasák, Vojtěch ; Formánek, Marian (referee) ; Počinková, Marcela (advisor)
This dissertation is divided into three parts. The first part deals with the use of waste heat in the theoretical plane, where methods and possibilities of using this heat are described. Part Two, which is computational, deals with the suggestion of heating industrial halls with an adjacent, mostly office, building in two variants, then it goes on to also deal with the concept of equal pressure forced ventilation, a proposal of air curtains and preparation of hot water, where the heat source is a boiler. In the last part an experiment took place which investigated the conversion efficiency of thermal to electric energy.

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.

Optimalize Application of Cascade Convection of a Heat Pumps
Hrnčíř, Zdeněk ; Šenk, Josef (referee) ; Gregor, Jan (advisor)
The introductory part of this diploma work contains a basic thought for the application of the heat pumps cascade connection and further I describe its function and define the notion of an optimum middle temperature.Then the direct comparison of two heats pumps cascade connection with an one-stage heat pump is shown there in a concrete example. The main part of the work is aimed to the determination of the most suitable variant for the heating and for the preparation of a hot service water in a benchmark family house. The systems of heatings are provided in options of a low-temperature floor heating and hot-water radiators. Both types of the heat pumps supply the warm to every heating system. It results into four possibles alternatives of the building heating.Besides of the alternatives mentioned above, a new variant of optimalised cascade connection was arisen during this work elaboration . The first stage of this connection which supplies the warm to the floor heating is disconnected out of the heating season and the second stage provides only a hot service water warming. The results of this work showed us that just this variant of a cascade connection causes savings in energy in comparison with an one-stage heat pump. In the conclusion of this work there are discussed the reached results and indicated the possibilities of a practical exploitation.

Design of a space heating system with a heat pump air-water and solid fuel source for heating the family house
Španihelová, Kateřina ; Elcner, Jakub (referee) ; Katolický, Jaroslav (advisor)
The aim of this thesis is to design the heating system for the house, including the design and calculating the required quantity of heat for hot water. The specified heat sources are the heat pump air to water and solid fuel boiler. The task was to design the heating system to the fastest possible return on investment. The initial investment in a heat pump is high so it is necessary to design the heating system as efficiently as possible. The thesis contains a complete project of calculating heat loss of the building, the design of heating surfaces and their heat-technical calculation. There is included the design of the pipe system, the calculation of pressure loss and its regulation. The thesis also includes design of safety equipment, temperature regulation and drawings. On the basis of calculated data was processed economic assessment, which determines the return on investment to the heat pump. Compared to the gas condensing boiler the return on investment will ideally be after five years.
