Ověření funkčnosti počítačové simulace v oblasti tepelných vlastností forem / Verification of computer simulation in the field of thermal properties of foundry mouldsŠupa, Jan January 2013 (has links)
This diploma thesis deals with thermal qualities of moulding mixtures of foundry mould of various types of sand grains and a computer simulation of the solidification of the cast. The aim of this work is to compare the values of thermal qualities of moulding materials bonded with water glass taken in experimental measurements to the values of thermal qualities of moulding materials connected with organic binding agent contained in simulation software. A sample cast will be moulded in order to evaluate cooling capacities of individual moulding mixtures according the shift of thermal axis. These results will consequently be compared to the results of the simulation.

Nízkoteplotní vytápění / Low temperature heating systemHrubý, Jakub January 2013 (has links)
The aim of this thesis is to design a low temperature heating system which will be operating in multifunctional wooden house. Ground souce heat pump being the pruducer of the energy in this systém, while the underfloor heating.being the consumer. After a short brief on theoretical level of used systems and devices, there comes a practical part of equations, designing and finding of a best solutions for all necessary parts of heating system. All imporant generated data are packed in a lucid charts. Thesis is trying to be somewhat brief but factical, and just a little bit stylish. At the end of the work there are some economical conclusions of used system like annual energy consumption cost, payback periods comparisons to other systems etc.

Srovnání možných způsobů zásobování rodinného domu energií / Comparison of energy sources for energy supply of residentialŠpatenka, Jindřich January 2014 (has links)
This diploma thesis deals with comparison of possible ways to supply the specific house by thermal energy. In the first part is a brief introduction of the building and determination of heat consumption. Following chapters are devoted to description and sorting of gas boilers, heat pumps, biomass boilers and solar collectors, inclusive the choice of specific source of heat. In the following part is stated economic evaluation of selected heat sources. Final part of the thesis is focused on design of additional exchanger instead of gas boiler.

Vytápění a chlazení RD s kombinovaným systémem dodávky tepelné a el. energie / Heating and cooling for residences with complex energy supply systemPavlíček, Michal January 2015 (has links)
Heating and cooling along with the indoor air quality is now discussed topic not only in the family houses. Goes hand in hand with reducing the energy consumption of buildings. This fact is edited by various laws or Regulations, no matter we discuss new buildings requirements, or for example energy label on older constructions.

Optimalizace zdrojů tepla pro bytový dům / Optimization of heat generators for residential houseSmola, Vojtěch January 2016 (has links)
This diploma thesis solves design of heating in a residental building. This work is focused on the selection of appropriate one of the two options a heat source, which are cascade heat pumps ground-water and gas condensing boilers. The theoretical part of the diploma thesis deals with introducing to the issue of heat pump systems. The functional principle of the widely most used types and particularized type ground-water. In the practical part calculation and design of heating system with selected heating source that is cascade of gas condensing boilers.

Tepelné a světelné poměry u automobilového světelného zdroje nové generace / Study of the thermal and light conditions in the automobile headlamp with built-in light source of the new generationZachar, Martin January 2016 (has links)
This thesis deals with automotive headlamps, focusing on layout of temparature field and its influence on thermal stress of used materials, describes their history, kinds and ongoing research. Thesis shortly describes light and its characteristics, heat and heat transfer and means of temperature measurement. Main part of the tesis is dedicated to measuring front headlamp serving as a fog light, concretely measuring temperature field and illuminance depending of ambient temperature. Thesis contains everything from the first preparations, creation of measuring circuit, programming of measuring to processing acquired data. Thesis also compares cooler used for cooling luxmeter sensor, the comparision is between measured values and created simulation.
