Increasing the energy efficiency of industrial heating plant
Spišák, Lukáš ; Lisý, Martin (referee) ; Kracík, Petr (advisor)
This bachelor thesis consists of two parts. The introductory chapters are devoted to the basic description of cogeneration and trigeneration technologies, focusing on the description of cogeneration units and cooling devices. The second part of the thesis compares two specific ways of using cogeneration units and gas boilers in the CHEMOSVIT ENERGOCHEM a.s. in the town Svit. Subsequently, both variants are evaluated energetically and economically.

Heat processing principle of operation thermal resistance annealing.
Špičková, Petra ; Humár, Anton (referee) ; Kalivoda, Milan (advisor)
The project assigned for the bachelors study program B 2307 analyses the theory of heat processing in general and furthermore resistance annealing with the focus on the technology developed by the company Heatmasters. Examples of processing methods used at other technology providers are presented, inclu-ding documentation and datasheets. Resistance annealing is based on the heat transfer from a resistive wire, which heats up by electrical current. The thermal energy is then transferred to the target material through heat radiation or con-ductance. The resistance heat processing is used both for welding and for an-nealing. Nowadays is the documentation and recording of the heat processing of significant importance. Possibilities exist that allow recording of temperature during the entire cycle of the heat processing and subsequently providing the result evidence in a form of a certificate.

Temperature measurement of a machine tool
Novotný, Petr ; Merenus, Ondřej (referee) ; Hermanský, Dominik (advisor)
The aim of this work is to get acquainted with the problems of temperature measurement, various types of non-contact temperature measurement and types of non-contact gauges. It also tries to explain the basic concepts and knowledge from the field of machine tools and their thermal load. Part of the thesis is to test this knowledge using measurements at Intemac Solutions s.r.o. The acquired knowledge is then evaluated using graphs and tables.

Budisov-Biomass heating plant
Petrovský, Jiří ; Baláš, Marek (referee) ; Fiedler, Jan (advisor)
This dissertation contains a comparison of the real possibilities for heating reconstruction and TUV reheating in three public buildings (located nearby one another) in Budišov township, with resulting recommendations of the best options for local operating conditions. The dissertation contains calculations of heating requirements for particular buildings, a generic theoretical part which summarizes basic data concerning long-term fuels (biomass and natural gas), proposals for technical solutions to heating sourcing concerning these fuels and its prospective distribution from a central boiler house, and its reciprocal comparison from the perspective of the economics of actual realization and operation, and from a perspective of fuel availability and ecology.

Využití aktivometrů v řízení reprodukce holštýnského skotu na ŠZP Žabčice
Šalšová, Agáta
This bachelor thesis focuses on heat detection in cattle. The thesis introduces the description of the female reproductive system, estrous cycle and its neurohormonal control. It further discusses heat and its signs – primarily an increased physical activity and what it is affected by. It explores different models of activometers; more specifically an activometer model Ovalert, which is currently used in a school farm Žabčice. The thesis concludes that activometers are very beneficial tools for breeding. They significantly facilitate work and save time. They can also duly detect and alert you to certain health conditions related to the observed parameters such as decreased activity, rumination intensity or feed intake.

Design and verification of a thermodynamic sensor with a focus on high sensitivity
Staroštík, Petr ; Jankovský, Jaroslav (referee) ; Otáhal, Alexandr (advisor)
This work deals with the issue of using bolometers, calorimeters a thermo-dynamic sensor in measuring temperature and heat. In the case of bolometers and microcalorimeters are described their properties and limit parameters. The work focuses more closely on the construction of a thermodynamic sensor from discrete components with a focus on achieving high sensitivity. The sensitivity of the thermodynamic sensor was measured in an experiment with a defined heat change and evaluated. Using this experiment was set the measurement methodology, which was subsequently modified. As part of the bachelor's thesis was designed a new sensor for a thermodynamic sensor and was measured its sensitivity.
