Heating of the School Building
Holková, Soňa ; Wierzbická, Helena (referee) ; Vendlová, Lucie (advisor)
The subject of this bachelor's dissertation is heating of the Primary and the Kindergarten school's buildings. The main aim is to make a design of the heating system and the hot water preparation. The source of the heat is the hot-water pipe, which the buildings are connected trough the heating coil to.

The finite element method for problems of heat transfer
Čupr, Pavel ; Chabičovský, Martin (referee) ; Štětina, Josef (advisor)
The study is focused on the research of heat transfer problems when assessing building constructions. It contains an overview of heat transfer theory, basic principles of method of advanced composites (MAC) and an outline of currently available MAC programmes based on open code. It researches the building constructions in terms of the heat transfer. The assignment uses analytical and numerical modelling of Ansys programme. Finally, acquired results have been compared and building constructions have been studied with regard to acceptability of different sets of temperatures.

Reducing the energy demand of a family house
Ondrák, Adam ; Kudela, Libor (referee) ; Pospíšil, Jiří (advisor)
The thesis deals with the issue of reducing the energy intensity of a family house and it approaches this issue in three steps. Firstly, the examination of the heat loss of the whole building, using the standard ČSN EN 12 831 and thermal vision. Subsequently, this is followed by the choice of the most economically suitable solution, so that the most modern technologies for reducing heat losses can be utilized and the project repays as quickly as possible. Furthermore, we will find the most suitable variant of a photovoltaic power plant, with regard to different types of photovoltaic panels. In conclusion, the price of the entire project and its repay and then other measures, that could be used to reduce project costs or the acquisition of additional equipment to reduce energy consumption, are listed.

Diagnostics and proposal to eliminate thermal bridges buildings
Bravenec, David ; Janík, Zdeněk (referee) ; Kalousek, Miloš (advisor)
This thesis presents a comparison of building materials for vertical bearing structures of buildings, thermal insulation materials and mutual combination of structural materials and insulators. Furthermore, there are possibilities for solving the most common insulation thermal bridges construction. The paper evaluated the pros and cons of different combinations of building materials. Teplo and Area programs were used for the calculations.

Indirect air heating
Beneš, Josef ; Adam, Pavel (referee) ; Počinková, Marcela (advisor)
The master Thesis deals with indirect air heating in air handling units. In the theoretical part of the thesis the categories of heat exchangers are defined according to their positioning in ventilation system, used material and type of heat transfer fluid. To the issue of calculating heat exchanges through heat exchangers and description of different kinds of regulation of primary heat transfer fluid is dedicated a separate chapter. The experimental part of the thesis deals with determining performance of current air heat exchanger at set thermal gradient with various heat transfer fluids. In the calculating part of the Thesis, based on measured values, are suggested two possible solutions for use of technological waste heat. Final evaluation of particular solutions was based on the criterion of efficiency usage and implementation investment costs.

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.

Influence of insulation of a guest house on expenses related to the operation of the property
Mach, Stanislav ; Čech, Josef (referee) ; Nykodýmová, Veronika (advisor)
The thesis solves the construction of the pension and deals with the assessment of the impact of the thermal insulation on expenses related to the operation of the property. The pension is situated on the street Valtická in Mikulov. The building has one floor and is founded on strip foundations. Roofing of the house is solved with irregular gable roof. In the first part of the thesis is a theoretical introduction mentions the possibility of building insulation and insulation methods. In the practical part of the thesis is an assessment of the heat transfer coefficient of the pension and costs associated with heating. There is also a proposal for modifications of the envelope construction with assessment of the heat factor and there are also proposed modifications to reduce the costs of operating the property.

Draft boilers for co-firing blast furnace gas and coke oven gas
Machara, Radek ; Křemínský, Pavel (referee) ; Baláš, Marek (advisor)
The diploma thesis deals with design of gas steam boiler with given parameters of steam. Blast furnace and coke oven gas are used as fuel. At the beginning of this work, both co-fired fuels are presented to us, their chemical analysis and stoichiometry are performed. The main part of the diploma thesis deals with the dimensioning of individual heat exchange surfaces such as steam superheaters, evaporators, economizers and air heaters. All heat exchange surfaces meet recommended parameters such as recommended steam rates, flue gas, etc. At the end, the total heat balance of the boiler is performed. Part of the work is also drawing documentation showing the main dimensions of the boiler. It is also indicated the connection of individual heat exchange surfaces.
