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.

Heat loss of buildings and proposals for measures to eliminate them
Nguyen Khac, Hoang ; Poláčik, Ján (referee) ; Baláš, Marek (advisor)
The bachelor thesis deals with calculations of heat loss in buildings and proposals of meas-urements. Thesis is divided into 5 chapters. In the first one there are reasons to insulate buildings, the process of material selection and furthermore there are descriptions of each materials used as insulation materials. In the second chapter there is the description of the model house, which is analysed in the thesis. The third one is about the calculation proce-dure. In the fourth chapter there is the proposal of reconstruction and in the last, fifth chapter there is an evaluation of reconstruction from financial standpoint.

Substitution of steam by hot water in heat distribution net
Mužila, Martin ; Baláš, Marek (referee) ; Pospíšil, Jiří (advisor)
The work is focused on area of exchanging steam distribution net for hot water one, in central distribution net of Martin’s heating plant. The main subject, which talks about pros and cons in this exchange process, is determination of heat losses which are created on heat distribution net during different operating status. These heat losses are calculated and on their basis some conclusions are concluded. Moreover, new heat exchanger is designed for certain conditions and also mathematical model of distribution net is created, which is suitable for checking different operating status. As a result of the work is technic’s and economic’s analysis of this project.

Reconstruction of a School building heating system
Kozák, Karol ; Košner, Jan (referee) ; Hejčík, Jiří (advisor)
This master's thesis pertains to designing a new heating system in secondary grammar school's building in the city of Vlašim. The old heating system is going to be replaced completely for a new system consisting of panel radiators and distribution piping network made of copper. Thesis includes technical description of old heating system and building itself, calculating of suggested heat efficiency using calculation software TechCON, selection of new panel radiators and appropriate dimensions of piping network , calculation and regulation of pressure losses, description of heat source and inspection of its safety components - expansion vessel and safety valve, determination of system for measurement and regulation as well as calculation of equithermal curves of this system. Last but not least total usage of heat is calculated. Blueprints of heating system are included as well.

The Earthship concept and its energy design
Peciarová, Michaela Mária ; Charvát, Pavel (referee) ; Mauder, Tomáš (advisor)
Táto práca popisuje koncept Zemelode ako sebestačný, udržateľný solárny pasívny dom a taktiež poskytuje podrobný opis energetických systémov v Zemelodi. Práca sa tiež snaží určiť energetický potenciál konceptu Zemelode pomocou odhadu energetickej bilancie daného obydlia. Celkový prehľad ideológie Zemelode a detailný opis energetický systémov, ktoré predstavujú tému čitateľovi, boli získané z publikácii rešeršom. Energetický výkon tejto stavby bol vyhodnotený podľa českých a európskych noriem pomocou výpočtu tepelných ziskov a strát pre zvolený model Zemelode. Následne, boli skontrolované kritéria pasívneho domu. Výhody a nevýhody tohto konceptu boli kriticky zhodnotené na základe rešeršu a výpočtu energetickej bilancie. Zhodnotenie výkonu zvoleného modelu Zemelode ukazuje, že toto obydlie nespĺňa požiadavky pasívneho domu, avšak stále sa jedná o nízko-energetický dom. Vykonaný rešerš ukazuje, že tento dizajn je vysoko závislý od podnebia a ročného obdobia, preto nemusí fungovať všade vo svete.

Complex Production Line for Through Hole and Surface Mount Components Assembly from energy saving point of view
Tomanček, Maroš ; Zatloukal, Miroslav (referee) ; Starý, Jiří (advisor)
Thesis deals with analysis of electronic assembly line from an energy consumption point of perspective. The throughput rate is observed along with consumption of individual devices from the chosen assembly line at Resideo company. The work load balance of the assembly line was evaluated by cycle time analysation. Electrical power and losses were measured with the use of power logger and a thermal camera. The possible energy saving solutions are then concluded from analysis and comparison of power drawn by the devices. Use of low temperature solder alloys and other modern industry solutions were considered with recommendation to be used in the field.
