Design of heating system for multifunctional building
Illichman, Petr ; Horák, Petr (referee) ; Vyhlídalová, Karolína (advisor)
The Bachelor thesis is divided into the theoretical part, the computational part and the project. Theoretical part consists of the basic description and the division of the fittings in a heating. In the computational part, I deal with heating proposal and a hot water preparation in the building of a multifunctional house st. Anny, located in Brno. The building has a four floors and the basement, commercial space, garages and apartments. The building designed with the gas condensing boiler and the indirect heating tank for domestic hot water use, the heating of the building is supplied the by plate and tube radiators. The project contains technical report and drawing documentation.

Heating of flat house
Hánl, Jiří ; Počinková, Marcela (referee) ; Topič, Jan (advisor)
The theme of my bachelor´s thesis is heating proposal and hot water preparation in apartment house. The teoretical part is focud on applicability and constructional solution of fittings. The calculating part consists of heat source proposal, hot water preparation, distribution of heating water and heating elements design. In the building there are proposed two heat sources, the first one for heating water and the second one for hot water preparation. The heating elemets are panel, tubular and floor convectors. The project part consists of technical report and drawing doocumentation.

Building Services in Low-energy Building
Fireš, Michal ; Tůmová, Eliška (referee) ; Hirš, Jiří (advisor)
The theme of my bachelor´s thesis is to analyse a building P4 of scientific and research center AdMaS (Advanced Materials, Structures and Technologies) in Brno and results compare with real values. The second part is heating proposal. Building P4 is composed of two side halls and stores, which are connected with central fourth-floor administrative building. The teoretical part is focud on nearly Zero Energy Building. The calculating part consists of heat loss calculating, heating elements design, hot water preparation and distribution of heating water. Heating elements are designed as panel and tubular. The part of project part is technical report, drawing documentation and the evaluation of present condition of building services.

Thermal calculation in design of resistance and induction devices
Krčál, Vít ; Foral, Štěpán (referee) ; Lázničková, Ilona (advisor)
This bachelor’s thesis focuses on thermal calculation of electric heating device and related theory. Selected topics in electric heating technology are explained, followed by the calculation in design of a crucible furnace and its automation using a computer program. The theoretical part first deals with the heat transfer mechanisms and their mathematical description. Further on, the thesis describes how heat is created in resistance and induction heating devices and mentions applications of these types of heating. The main part of the thesis focuses on the thermal calculation of the resistance crucible furnace for aluminium melting. The calculation relates to a cylinder-shaped model of the furnace with determined structure and deals mostly with heat loss, electric power input, thermal efficiency and design of heating elements. The calculation is achieved only in general and it is subsequently automated in Microsoft Office Excel® application. The computer program, which is also a part of the thesis, allows user to change input parameters and see how it affects results of the calculation. In the last chapter, an example of calculation for specific numeric data is presented. The main goal of the thesis is to automate the calculation. That can save some time while calculating and designing a crucible furnace.

Calculation of resistance furnace with indirect heating
Bezecný, Ján ; Radil, Lukáš (referee) ; Lázničková, Ilona (advisor)
The content of the submitted thesis is to determine a methodology for calculation resistance furnaces with indirect heating. In developing of the methodology, we used the theoretical knowledges of converting an electricity to heat and its sharing with an environment, and practical experiences in a construction of resistance furnaces and heating elements, with respecting of economical efficiency of production. We were applied these knowledges in designing of furnace for hardening the classic sodium-calcium glass, with a volume of the batch 2 dm3, that are in industrial practice used mainly in construction, as well as the commercial glass. These furnaces are used by small and medium companies, that are focused on custom pieces, respectively small batch production. Within the methodology, we determined appropriate type of furnace and furnace lining, by defined required size and temperature of the batch. From the values of the heat, required for heating-up the batch and cover the heat losses, we calculated the the required electric power, specific consumption energy and efficiency of electric furnace. At the end we designed the dimensions and layout of heating elements.

PSpice library of circuit elements with selfheating
Šrut, Martin ; Petržela, Jiří (referee) ; Kolka, Zdeněk (advisor)
This bachelor´s thesis is devoted to the topic PSpice library of circuit elements with selfheating, which deals with the lack of temperature in the PSpice and design models of the resistor, diode and transistor to the treatment of this problem. The thesis describes theoretically Electrothermal analogy, creating a thermal equivalent circuit model and the theory of creation diodes and transistors. The next step is a theoretical design procedure of general circuit, theory of system libraries and netlist in PSpice and a description of ways of creating subcircuits. Their own solution the whole thesis is creating a model of a resistor, diode and transistor with self-heating. Furthermore, the results are shown simulations of the models. Transistor model is tested on the output stage audio amplifier together with a model heatsink.

Heating of the Training Center
Matoulková, Jana ; Topič, Jan (referee) ; Vendlová, Lucie (advisor)
The aim of this thesis was to design heating a training center in the Velke Mezirici. The heat source was designed gas condensing boiler, which covers the requirements for the heating system and heater air handling unit with heat recovery. The heat source is located in the utility room on the first floor. The building was designed by panel radiators and convectors bench.
