Heating historic building alternative fuels
Lampa, Jan ; Ing. Vrána (referee) ; Vališ, Ivan (advisor)
The introduction of theoretical part deals with issue of fuel. There are basic kinds of fuels, their properties and calorific values. In next part a summary of types of boilers depending on the kind of fuel is described. A process of burning in each type is discussed. Then the basic issue of heat transmission, heat losses and design of individual elements of central heating system is described. In the second part there are two studies compared to each other. In the first one an automatic pellet boiler is used as a source of energy and in the second one it’s a heat pump, type air-water. At the end both of the variants are reviewed and the better option is chosen. In the last part the better option is designed, into detailed design documentation. Important design values for using the heating system and hot water service are calculated.

Application of renewable energy sources in civil construction
Sedlák, Tomáš ; Počinková, Marcela (referee) ; Horák, Petr (advisor)
The aim of this Diploma thesis is the design of solar collectors. The thesis is consists from three parts. The first part describes the technical design of solar collectors and solar systems. The second part contains with design size of the collector area for the two selected variants. The third part addresses the experimental measurements located on the real building. The output of third part is the economic evaluation of the solar system.

Application of Renewable Energy Sources for the Family House Heating in Bosnia and Herzegovina
Štefková, Daniela ; Topič, Jan (referee) ; Vendlová, Lucie (advisor)
Diploma thesis is focused on renewable energy sources and its applications for heating of family house in Bosnia and Herzegovina. The project contains two design variants which are described in part B in detail. Alternatives are compared in conclusion and the most suitable one is chosen for given building. The part of experimental solution deals with measurement of solar intensity and air temperature in Bosnia and Herzegovina and in the Czech Republic. Obtained data are processed, compared and graphically represented. Experimental part also includes stationary state simulation of floor heating carried out in CalA software. Simulations were made in different variants.

Hydraulics solar systems
Podjuklová, Lucie ; Topič, Jan (referee) ; Počinková, Marcela (advisor)
The project addresses in the theoretical part of the hydraulics of solar systems and her components, which are used to design a solar system on apartment house. Solar systém addresses praparation hot water in two variants of the solution. In the first alternative solution is used low flow and 15 l/hod.m2 support stratification. In the second variant is used higher flow 20 l/hod.m2 without support stratification. In the experimental part is solved by the data analysis of the same apartment building, where the solar system are already installed and operated. Some data from the measurement was taken into account and used in the design and calculation of both options.

Charge controller for solar panel based charging of lead-acid batteries
Korenčiak, Peter ; Štohl, Radek (referee) ; Fiedler, Petr (advisor)
Tato diplomová práce se zabývá návrhem a realizací regulátoru pro použití v solárním systému s větším počtem olověných akumulátorů. Takový regulátor umožňuje nezávislé připojení a řízení nabíjení většího počtu akumulátorů různého stáří a parametrů. To je v kontrastu s řešeními obsahujícími jedno připojení pro více baterií připojených paralelně, kde se míchání baterií různého druhu a stáří nedoporučuje. Tento regulátor nabízí vysokou škálovatelnost skladování energie v solárním systému. Umožňuje také používat starší baterie s novými, místo nutnosti staré baterie nahradit, když jejich kapacita klesne pod požadovanou úroveň. V této práci jsou podrobně popsány požadavky, návrh hardwaru a softwaru a implementace regulátoru s nominálním výstupním proudem 20A pro pět 12V olověných baterií. Práce popisuje také další funkce, stejně jako alternativní návrhy a algoritmy. Důležitá část práce se zabývá designem spínačů pro velké proudy, ochrany proti zkratu a obvodů pro měření stejnosměrného proudu. Správná funkčnost regulátoru byla ověřena měřením.

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.

Analysis of the economic efficiency of a solar system
Mikl, Antonín ; Pithart, Jan (referee) ; Macháček, Jan (advisor)
The Master’s thesis deals with the processing of solar thermal systems for heating hot water, outdoor swimming pool and heating selected house. Introduces us how we can use the sun for the production of thermal energy through solar collectors. Furthermore, the basic components of the solar system and the types of collectors used. After this summary on the present state be the calculation of the system and fixing the price of the investment. The economic part of the evaluate if this system to invest, eventually appoint a return on investment.
