Optimizing The Design of Dry Floors
Hlavsa, Petr ; Chybík,, Josef (referee) ; Klečka,, Tomáš (referee) ; Tuza, Karel (advisor)
This dissertation deals with the optimization of the dry floor design by solving the innovative floor composition supported by the development of a new floor element, doing so from the point of view of building physics – especially the heat and mass transfer in buildings – with the consideration for the benefits for acoustics. It is aimed at dry floors application to modern timber structure. In the area of heat and mass transfer in buildings, the impact of thermal stability of rooms and its increase in the use of a new floor structure is investigated with the inclusion of a proposed element improving the thermal storage capacity of the floor. All this in the context of ensuring the possible floor heating integration. In the evaluation of thermal stability in rooms, those operating conditions that are accompanied by interrupted heating, are considered to be key. After describing the current state of solving this issue, the main focus of this dissertation is its own development and design of a specific floor element and its integration into the floor composition. An important part of the dissertation consists of related numerical simulations, its own experiment, relevant measurements in the experimental object, and their evaluation.

Heating of Veterinary Clinic
Marčiš, Šimon ; Topič, Jan (referee) ; Počinková, Marcela (advisor)
This bachelor thesis examines a design of water heating and heating system for Veterinary clinic in Horný Hričov. The theoretical section reviews basic aspects of heat pumps like history, operating principles, types of refrigerants used and basic classification of heat pumps. A specific attention is paid to the brine/water heat pump type which is analyzed in detail. The analytical section of this thesis consists of complete calculation and design of the heating system and water heating. The third section of the thesis comprises a project elaborated to the level of a realization documentation for the construction. The project consists of a technical report and a drawing documentation.

Heating of the kindergarten
Jetelina, Michal ; Wierzbická, Helena (referee) ; Počinková, Marcela (advisor)
This work is solving the proposal of heating a kindergarten. The theoretical part is focused on warm water heating, which is used in the proposal. The computational part includes a proposal of heating the building. The system is a combination of low temperature system and underfloor heating. As a warm source, there is a design of thermal pump of air and water, which is located in exterior. The ventilation of the building is natural or forced, depending on location. The work contains proposal of all needed equipment and also the design of the source of warm water.

Heating of the exhibition rooms
Ženíšek, Pavel ; Vendlová, Lucie (referee) ; Vendlová, Lucie (referee) ; Počinková, Marcela (advisor)
The bachelor thesis delas with the heating of the exhibition rooms and preparation of the warm water. The building will be heated by plate radiators, convectors and underfloor heating. As a heat source is used a heat pump. Warm water is prepared in the DHW cylinder, heated by the heating water from the heat source. The project deals with the desig,n dimensioning and connection of these parts. The thesis also includes a theoretical part on the topic of underfloor heating.

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 the pedagogical advisory centre
Šrámková, Denisa ; Vendlová, Lucie (referee) ; Počinková, Marcela (advisor)
The bachelor's thesis deals with the design of the heating system of the pedagogical counseling center. The theoretical part of the work deals with the energy performance of buildings and a certificate of energy performance of the building. The calculation part deals with a separate design of the heating system and its partial elements. The calculation part also deals with hot water heating and heat accumulation. An air / water heat pump is designed as the heat source. The building is heated by radiators and underfloor heating. The entire technical solution is described in the technical report, including requirements for other professions.

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.
