Economy and ecology of biomass utilization
Plíšek, Petr ; Špiláček, Michal (referee) ; Pospíšil, Jiří (advisor)
This bachelor thesis deals with an economic and environmental contexts of biomass utilization. The first part focuses on the description of the nature and manner of use of biomass. Another part is focused on economic aspects related to biomass. A necessity in the processing a particular energy source is its ecological problems, that is the third chapter. The last part is devoted to the design condensing heat exchanger and its output relative to the fuel wetness content, and boiler output with a condensing exchanger depending on the combustion products cooling temperature.

Air cooled condenser
Bochníček, Ondřej ; Kracík, Petr (referee) ; Pospíšil, Jiří (advisor)
This master´s thesis deals with an air cooled condenser. The specific attention is focused on the condenser in the Brno´s waste-to-energy plant SAKO. The general process of calculation of the heat transfer coefficient is introduced, which is the base for the calculation of the condenser´s output. This process is later used for the calculation of a specific condenser. A considerable part of the thesis is concentrated on the analysis of behavior of the condenser of SAKO in various conditions from the theoretical point of view and then also in terms of real operation using provided operational data.

Sensor of condensed moisture
Krejčí, Jakub ; Havránek, Zdeněk (referee) ; Beneš, Petr (advisor)
This master thesis deals with measuring condensed moisture in constructions using measuring moisture porosity material. Market research was performed and were made sensors own construction based on capacity principle and their attributes were measured. In this thesis is also described method, which is used for calibration for conditions in building constructions causing condensation of water.

Commented translation: Bien vivre avec son chat (Muriel Alnot-Perronin, Paris: Rustica Éditions, 2008)
Flanderová, Kristýna ; Belisová, Šárka (advisor) ; Šotolová, Jovanka (referee)
The work consists of two parts, translation and its commentary. It is a translation of a French breeders guide Bien vivre avec son chat - the chapter about feeding and the first part of the chapter about cats hygiene and care. I preserved the main function of the original text in the translation - to provide information to the recipient, to give them useful knowledge and advice. In the second part of the work, I reflect the problems of the translating process. First, I characterise in detail the original text, regarding both extratextual and intratextual factors. Then I focus on individual translation problems and create the typology of the problems. At the end of the work I summarize the methods used in the translation.

Hygrothermal processes in walls of wooden houses
Vencel, Lukáš ; Vlach, František (referee) ; Bečkovský, David (advisor)
This diploma thesis solves the problems of hydrothermal processes in walls of wooden houses and associated issues. A chosen were two apartment buildings, where they underwent exmerimental measurement of indor air, in order to determine the boundary conditions commonly boundary building evelope. Was followed by hygrothermal analysis of four commonly used constructions of wooden buildings in the Czech Republic, using various numerical methods. The quantity of information obtained from various numerical methods were analyzed individually. The final part of the thesis is devoted to experimental measurements of diffusion properties of materials. Namely foil vapor barrier, in terms of its influence on the perforation vapor diffusion resistance factor. Information obtained from the experiments were applied to re numerical analysis for walls with a foil vapor barrier. Followed by comparing both cases, in terms of changes hygrothermal behavior of structures with influence of perforation of the vapor barrier.

Building physics assessment of the roof structure
Konopík, Petr ; Janík, Zdeněk (referee) ; Kalousek, Miloš (advisor)
This theses deals with a structural design comparison of heat insulations implementation in flat roofs in light of heat engineering. It also adverts to possible structural design in terms of heat insulations distribution in a flat roof. There are many materials options. I show the possibilities of material solution and also advantages and disadvantages of the single sealing materials at these layers. In the aplication part of this thesis I deal with possible concepts of insulation and solution for a specific roof of an older apartment house in Brno, where I conducted a constructive exploration. There was developed and evaluated a few options of solutions considering the heat insulator used. The following computational programs were used for the evaluations: TEPLO, AREA, CUBE 3D.

The concept for passive cooling of the VVER-1000 reactor
Lamoš, Pavel ; Suk, Ladislav (referee) ; Martinec, Jiří (advisor)
This thesis is focused on the design of passive cooling system for a nuclear reactor VVER- 1000.This type of reactor is located in the Czech Republic in the location of Nuclear power plant Temelín. The thesis states an overview of the different cooling systems of nuclear power plants. The thesis is focused on passive safety system especially on passive cooling system, so there was done an overview of currently used passive safety system. In the work is discussed nuclear safety and the maximum projected accident of VVER-1000, which is called LOCA accident. In the design part of the thesis was done thermal calculation of heat exchangers. Exchangers are designed as condensers with a natural flow, where cooling of system is provided by outside airflow in case an accident. The results are evaluated at the end of the thesis.

Dewing sensor
Voda, Tomáš ; Antonín,, Žák (referee) ; Beneš, Petr (advisor)
This work consists options of measuring condensed humidity and moisture in material, which buffs this moisture. The work also describes design of testing plate in which condense humidity for testing dewing sensor. The work contains complete wiring of testing plate. The testing plate was build and successfully tested. Sensors were successfully tested in area of condensation.

Designing of a hot water heater
Zdražil, Pavel ; Frömel, Zdeněk (referee) ; Baláš, Marek (advisor)
This thesis processes design of hot water heater. It was done thermal, hydraulic and basic strength calculations in the work and from their outcomes was set up a design of heat exchanger, which was afterwards modelled and drawn. In the beginning of the work is reader introduced to heat exchanger types and characteristics and also to its thermal processes. Then the work continues with thermal design of the heat exchanger, where the most important outcome is heat transfer surface with other geometric parameters, followed by hydraulic design, where pressure loss on water side was calculated. The calculations are finished up by basic strength design, calculating thickness of shell and tube walls. The thesis is ended with evaluation of computed design and description of its basic features.
