Intelligent control of the storage water heater
Vašica, Radoslav ; Macháček, Jan (referee) ; Šlezingr, Jan (advisor)
The work generally deals with the possibilities of preparing hot water in household and analyzes saving posibilities. At the beginning of work the history of hot water preparation is briefly indicated. Chapter 3 deals with different ways of heating. Described in more detail electric storage heating is in chapter 4, where can be found the effect of heating to the power network, especially to the daily load diagram. The following are the information of the tariff policy, as a tool for motivation of consumers, for using the storage heating. In the next part, beginning with the fifth chapter, is written about the possibility of energy saving by means of intelligently controlled boiler. That eliminates the disadvantage of storage heating, which are the tank thermal losses. Heating is based on a certain regularity in the behaviour of the user and manages the preparation of water according to expected consumption. The sixth chapter then contains design of own algorithm for economical control of heating and also energetic and economic assessment of potential savings.

The development of the model of PV system for electric water heating
Sochor, Tomáš ; Radil, Lukáš (referee) ; Ptáček, Michal (advisor)
This thesis deals with designing of a model of a photovoltaic system for domestic water heating in program PSCAD. In theoretical part, an analysis of photovoltaic systems regarding their connection to electrical grid is made. Then a description of chosen concepts of photovoltaic systems for domestic water heating is made. Furthemore, a photovoltaic cell is described with regard to its mathematical description and influence of different parameters on its volt-ampere characteristics. Also, a common topologies of DC-DC converters are described. Control is also related to these converters, that is why a fundamental MPPT algorithms are described. Practical part deals with designing of chosen concepts of photovoltaic systems for domestic water heating in program PSCAD. A basic simulations with regard to behavior of these systems are performed, especially a relationship with respect to irradiance and temperature. Simulations are then discussed in the conclusion.

Energy Performance of Domestic Hot Water Preparation
Helánová, Blanka ; Vrána, Jakub (referee) ; Vendlová, Lucie (advisor)
Master’s thesis on Energy performance of domestic hot water preparation is concerned with calculating and comparing the energy performance of domestic hot water preparation in two-generation family house with an administrative part. Energy performance of domestic hot water preparation is calculated by two calculation methods and by experimental measurements, which are compared at the end of the thesis. The calculation is performed according to standard ČSN 06 0320 and set of standards ČSN EN 15316-3. Thesis is processed in accordance with valid legislative regulations.

Design of Heat Pump
Křepela, Radim ; Elbl, Patrik (referee) ; Toman, Filip (advisor)
The aim of this bachelor thesis was basic research in the field of heat pumps. Calculations for heating of domestic hot water were done afterward. The theoretical part describes basic principles of heat pumps and covers a wide range of currently used types of heat pumps. Heat pumps are categorized by the environment from which the heat is taken out of. The experimental part contains calculations and selection of commercially available main components. Components were chosen based on the ability to heat 1000 L of hot domestic water from 20 to 50 °C in 4 hours.

Proposal of heating from the perspective of the primary energy
Jurka, Vít ; Adam, Pavel (referee) ; Horák, Petr (advisor)
This master´s thesis proposal addresses the heating from the perspective of primary energy in the object. The building is located in Brno and is used as a villa with a pool hall. The object of this work is the selection of appropriate variants of three heat sources (gas boiler, pellet and electric) in terms of primary energy. The project is design of the heating system chosen mode of heat, which is a pellet boiler. The theoretical part is focused on the pellets and their history, classification, properties, production, storage and transport.

Energy Evaluation of Technical Services Systems
Cap, Petr ; Horák, Petr (referee) ; Vendlová, Lucie (advisor)
This Master’s thesis deals with the energy evaluation of existing buildings sports-recreational company complex in Brušperk. For this purpose provides a comparison of selected fuels as an energy source for the heating in terms of economy and their impact on the environment. In addition, provides an overview of existing legislation for elaboration of an energy audit. To complement shows the calculation of return on investment in solar panels on the roof of one of the objects. Calculation is based on the results of performed experimental measurement. Finally, the thesis presents a comparison of energy performance of buildings simulated in the Bsim software with reality.
