Posouzení dřevěných podlahovin vhodných pro podlahové vytápění

Peřina, Jakub January 2015 (has links)
The main objective of this thesis is to assess the suitability of multilayer wood flooring especially in terms of dimensional stability, which is the most important feature when combining flooring with underfloor heating. Part of the work is to describe the problems of floor heating from the perspective of the past and present point of view, mention types of flooring, including designs and flooring installations. The second part of the work is about issue of step layer suitable for underfloor heating, with a broader focus on wood materials, particularly engineered wood flooring. Work also includes measured values and processed to assess two three-layer flooring of different material composition. In conclusion of this work is indicated an assessment of available laminated wood flooring, which were examined in our test and also draft of new design flooring made of wood, which would improve the thermal effects of underfloor heating.

Energetická rekonstrukce samostatně stojícího rodinného domu / Energy retrofit of a stand-alone house

Stupka, Jaroslav January 2020 (has links)
The aim of the master’s thesis was to design heating, ventilation and cooling systems and to evaluate possibility of using renewable sources in case of a reconstructed two-storey family house. Air to water heat pump and floor system were designed to ensure both heating and cooling supply in the building. A heat recovery ventilation system was proposed. Gains of electrical energy from photovoltaic array were calculated and then possibility of coverage the heat pump consumption was evaluated. The thesis contains required calculations including building heat losses, heat gains, air exchange rates and the dimensioning of all mentioned systems. Technical drawing is also comprised.

Návrh vytápění a nuceného větrání pro rodinný dům Doubrava / Heating and ventilation in the "Doubrava" family house

Jirsová, Tereza January 2021 (has links)
The diploma thesis is focused on the design of heating and forced ventilation for the project of the family house Doubrava. In the first two chapters is briefly described the theory and there is also described the project of the family house. The next chapter deals with the design of the forced equal pressure ventilation with the heat and moisture recovery. Than the heat loss are calculated according to the norm ČSN EN 12831-1. The next part is focused on the design of heating system and the heat source for the family house Doubrava. There is described detailed design of the floor heating, including necessary calculations, and also the type of the heat pump, as the heat source and source for hot water heating, is chosen. This part also contains a selection of expansion tank and safety valve and approximate calculation of the size of the primar circuit. The last part deals with the possibilities of using renewable energy sources. At the end of the thesis, there are more detailed results of the calculations and the mechanical drawings of individual designs of the ventilation and heating system and also there are tables of the acquisition costs.

Nízkoteplotní vytápění / Low temperature heating system

Hrubý, 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.

Fyzikální jevy při dopravě vzduchu / Physical phenomena in air transport

Bělehrádek, Lukáš January 2018 (has links)
The aim of this thesis is to design an air conditioning system of a flat unit in two variants of piping. The piping system of the first floor is installed into the floor in one variant, in the other it is in the ceiling. Data received from measurements within the experiment have been used for the design. The result of the measurement are minor loss coefficient implemented for bending pipes and pressure losses caused by rubbing. These values are used for dimensioning piping variants. Both types of piping are described in the theoretical part and the method of how the experiment had been processed.

Podlahové systémy na bázi druhotných surovin z energetického průmyslu / Floor systems based on secondary raw materials from power industry

Kalina, Martin January 2014 (has links)
This thesis deals with the possibility of using secondary raw materials from the energy industry especially the solid residues of high temperature combustion of coal. These materials should be now seen as a material with wide usage especially in the construction industry. One possibility of their usage is a replacement of binding parts in floor systems. The aim is to find the optimal composition of the mixture, which fits all the technical requirements and at the same time reduces the cost of its production. An advanced methods of powder X-ray diffraction analysis, particle size laser diffraction analysis and X-ray fluorescence analysis were used to determine the raw materials. Based on these analysis the experiments were designed focusing on the mechanical properties, the observation of the evolution of hydration’s heat in prepared mixtures and their time of setting and hardening.
