Heat sources for an apartment building
Jurčík, Peter ; Horák, Petr (referee) ; Vyhlídalová, Karolína (advisor)
This master thesis deals with the design of a heat source for heating and DHW in an apartment building. The theoretical part contains a brief division of heat sources for an apartment building and introduction of the components of the solar system. Significant part si devoted to the T*sol software, which was used as a simulation tool for calculation of the solar system parameters. Finally, an article that addresses similar design of the solar system was analyzed. The calculation part deals with the design of the heating system. It consists of the calculation of heat losses, the design of heating elements, heat source and other components. DHW calculation is solved in two variants – var. 1 with gas condensing boiler and var. 2 with gas condensing boiler and solar system. The last part of the master thesis is dedicated to the design of a solar system for DHW using the simulation of several variants followed by selection of the optimal solution.

Systems of technical equipment in almost zero energy House
Bukovjanová, Eva ; Adam, Pavel (referee) ; Počinková, Marcela (advisor)
The aim of this thesis is the design and building services systems in buildings with energy close to zero. The thesis 2 variants were designed heating and DHW. In variant 2 is considered with the photovoltaic system to generate electricity that is used up mainly in the building. It is part of the thesis experiment, whose aim was to monitor and evaluate the structure of electricity consumption in the residential unit.

Building services of near zero energy bulildings
Fikejsl, Tomáš ; Komínek, Petr (referee) ; Hirš, Jiří (advisor)
The thesis deals with the issue will be nearly zero energy. The theoretical part is divided into several chapters. Describes the requirements of applicable legislation of the Czech Republic and the EU and the application of renewable energy in these buildings. The third and last part serves as a basis for part of the experiment. Calculation section applies theoretical knowledge into practice. The subject has become a new residential building in which they are designed to ensure the technical equipment required internal environment. The proposal concerns the heating, ventilation, cooling, domestic hot water and lighting. At the end are attached graphic of energy performance certificates (PENB) and evaluated the economic and ecological point of view. The experiment deals with the measurement of the internal microclimate administrative building type in Brno, with regard to the requirements of current legislation of the Czech Republic.

Using of Renewable Energy Sources for Family House Supply
Varmuža, Jan ; Macháček, Jan (referee) ; Toman, Petr (advisor)
This work is concerned to analysis and evaluation of present recoverable energy resources and position EU to them. In study is provided comparison of recoverable resources (biomass, water, wind, environment energy, and sun). The details are noted for all single cases. As the next addition are included various techniques „how to obtain and convert them“. In study are also noted which necessary equipments must be used and their proper location. In practical part is done comparison of barrier-layer photocell from polycrystalline and monocrystalline silicon and water insulating foil „EVALON SOLAR“. For comparison was taken only produced energy. Next step was financial analysis of each single system and comparison with pay-off in case that invested sum (actual price) was placed to bank under time deposit and share capital fund. During analysis of financial evaluation was found, that more suitable is system from polycrystalline silicon. Because of investors main condition is financial aspect, so for realization will be recommended system from polycrystalline silicon.

Design of heating system for low-energy family house
Kytýrová, Zdeňka ; Hejčík, Jiří (referee) ; Košner, Jan (advisor)
This diploma thesis deals with the design of a heating system for a "low-energy" house. It is conceived as a low temperature system using a combination of radiators and underfloor heating. The design is supplemented with a calculation of heat loss, a proposal of needed components, a scheme of the system and means of regulation. The second part solves the heat source selection. A solar system with vacuum tubes is used as the primary source. The second one is an electrical water heater located in the accumulation reservoir for the hot domestic water. Necessary calculations for the design of the solar system, together with a scheme and means of regulation, are enclosed in this section.

High temperature energy reservoir with year-round operation in conjunction with a solar system
Hoc, Pavel ; Šikula, Ondřej (referee) ; Hirš, Jiří (advisor)
In this thesis I deal with the issue of stand-alone solar system development. This system ensures the supply of all the energy needed for a reference house. It consists of a solar concentrator and a heat reservoir. I used mathematical models to solve this issue. The calculations showed, that the concentration of solar radiation into the heat reservoir can usually achieve 69 % efficiency. The efficiency can be even higher when using a very reflective materials of the solar concentrator. In this thesis, the thermal reservoir is described and its improvements are suggested based on the optimization calculations. Thanks to knowledge gained during solving this issue, a prototype of the stand-alone solar system is going to be built. All findings will be experimentally verified with this prototype.

Multiparameter circulating pump driver
Pazour, Zbyněk ; Frýza, Tomáš (referee) ; Kratochvíl, Tomáš (advisor)
This master’s thesis deals with design of the regulation of a circulating pump in a solar system for heating of supply water and design of the regulator for this system. It describes a fundamental principle and layout of a regulated circuit of a heating system. Description of regulation, basic terms, properties and differences between different types of regulation are described in first part of the master’s project. Especially continuous (PID regulator) and discrete (PSD regulator) regulation are presented. Second part of the master’s project is focused on a conceptual design of the circulating pump regulator. The connection system of each part, selection conditions of components and connection scheme of regulator are described. The third section deals with design of controlling algorithm of the regulator. There is a detailed description of libraries and functions in each chapter which were used in programming of PSD regulator algorithm. The regulated system of a solar collector is described at the end of the work. This system is being developed for real testing and setting of regulator.
