Design of experimental model of boiler
Kuba, Pavel ; Sikora, Michal (referee) ; Vlach, Radek (advisor)
This thesis describes the design of experimental model of boiler and identification of systems parameters. Model and measuring unit were designed on basis of research study. Data acquisition module NI USB-6216 was used to measure and transfer data to computer. Programe MATLAB was used to proces data.

Heat Exchangers
Rosypal, Štěpán ; Fortelný, Zdeněk (referee) ; Baláš, Marek (advisor)
This bachelor thesis shall inform readers about basis types of heat exchangers used in power industry and their basis sorting. They are sorted not only from the point of view of their purpose and function, but also, from the point of view of their construction. Apart from that, there is a comparison of recuperative heat exchangers. Moreover, the thesis deals with possibilities to enhance their efficiency, possible problems in service and ways to solve these problems, maily with sedimentation and cleaning heat exchangers.

Possibilities of heat transfer regulation while MIG/MAG welding
Mášová, Pavla ; Hála, Michal (referee) ; Daněk, Ladislav (advisor)
The project is elaborated in terms of bachelor's studies of branch 2307. The project is submitting possibilities of heat transfer regulation while MIG/MAG welding. Energy storage welding is a conventional method of heat regulation. Other methods were developed by company producing welding unit. A company Kemppi offers a method Fast Root for the heat regulation, methods Rapid Arc and Rapid Melt were developed by AGA AB and company Lincoln Electric offers a method Surface Tension Transfer. Method Cold Metal Transfer by Fronius company and ColdArc by EWM company are used for reduction of heat transfer into the weld steel-aluminium.

Temperature field analysis of spent fuel cask
Švaříček, Tomáš ; Nerud, Pavel (referee) ; Šen, Hugo (advisor)
The purpose of this thesis is temperature field analysis of spent fuel cask destined for dry buffer storage. Also to show possible ways of solving the difficulties in temperature field analysis, together with definition of simplifying presumptions and boundary conditions. Based on reasonable arguments were designed solving formulas, gained analytic solution of the temperature field and then compare analytical solution with numeric solution from ANSYS in the end of thesis.

Heat exchangers for air-conditioning
Pavlíček, Michal ; Jaroš, Michal (referee) ; Hejčík, Jiří (advisor)
The thesis is divided into 2 parts. The first part deals with classification and characterization of heat exchangers. The sizing process of plate heat exchangers is described and demonstrated in the second part. Obtained results are compared with real plate heat exchanger produced by Güntner Company.

Air conditioning systems of residential buildings and one-family houses
Verfl, Jan ; Fišer, Jan (referee) ; Janotková, Eva (advisor)
Airconditioning now a days became important equitment in every household. It keeps optimal microclimate and thermal comfort. The first chapter describes valuatiuon of microclimate and termal condition of enviroment and also termal transport in between human body and enviroment. The second chapter desribes conditioner and its main parts, division of aircondition systems and their estimation.

Ventilation and air conditioning of a car cabine
Viščor, Petr ; Hejčík, Jiří (referee) ; Fišer, Jan (advisor)
In this work are described kinds and functions of air-conditioning systems which are used in cars. Further is described heat transfer between car cabin and ambient environment and issue of reduction of air-conditioning energy consumption. Last part of the work contains numerical simulation made by the THESEUS-FE 2.1 software package. This simulation was done on a model of the Toyota Prius car and was focused on effect of glazing on a temperature of the air inside the car cabin during hot summer days.

Study efficiency of modern thermal insulation for buildings
Šot, Petr ; auditor, Karel Trojan, Brno, energetický (referee) ; Šťastník, Stanislav (advisor)
The bachelor´s thesis deals with the problem of thermoreflect insulation. The small part of thesis focuses on the energy demand of buildings and its problems. Then the greater extent is analysed problems by heat transfer of material. It includes effects arising from the individual methods of heat transfer and defines the level of expression of individual methods of heat transfer in materials. The thesis presents an overview of experimental methods for determining thermal insulating properties of insulators. Then there is shown a selection of the most widespread insulation materials used in today´s construction. It includes the division of insulators in terms of used materials and subsequent classification of the most used materials in these groups. Another part of thesis deals with the thermoreflect isolation. There are mentioned the necessary concepts for the study of thermoreflect thermal insulation, which include the emissivity surface, the coefficient of mutual radiation and translucency of the material. Then there is described the method heat transfer of thermoreflect isolation. On the next there are presented experimental methods of determining thermal insulating properties thermoreflect thermal-insulating material. The thesis also includes a practical part, which contains the measurement results on a small range of samples taken termoreflection insulators. In the end there is mentioned a brief realization of thermoreflection thermal insulation materials in buildings.
