Variantní řešení rekonstrukce systémů vzduchotechniky prostoru laboratoří / Variant solutions reconstruction of airconditioning systems in the laboratory

Faltys, Michal January 2015 (has links)
The diploma thesis deals with the designing and assessment of two variants of the reconstruction of the air conditioning system for the half of 3rd floor laboratory building BioVendor – Laboratorní medicína a.s. company. The system is proposed to fulfil hygienic, operational, economic and functional requirements for indoor microclimate of laboratories. The task of this system is the transport of fresh air to interior and the covering of heat gains in summer. The equipment is also designed for the regulation of air humidity in the interior. The theoretical part deals with the application of heat penetration of solar radiation double glazed construction. Calculating and project part deals with the specific proposal of two variants of a new HVAC system-level studies of which the selected variant is developed as the project documentation. Experimental part is devoted to measuring of CO2 concentration in operationally similar laboratory. The result of this work is to evaluate the operational and economic impacts on the choice of technically feasible options and implementation documentation selected option. The benefit of the experiment is to verify sufficient air exchange to ensure the optimum concentration of carbon dioxide in laboratories.

Teplotně vlhkostní namáhaní stěny dřevostavby / Hygrothermal processes in walls of wooden houses

Vencel, Lukáš January 2017 (has links)
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.

Technická zařízení budov v budovách s téměř nulovou spotřebou. / Building services of near zero energy bulildings

Fikejsl, Tomáš January 2017 (has links)
The thesis deals with the issue will be nearly zero energy. The theoretical part is divided into several chapters. Describes the requirements of applicable legislation of the Czech Republic and the EU and the application of renewable energy in these buildings. The third and last part serves as a basis for part of the experiment. Calculation section applies theoretical knowledge into practice. The subject has become a new residential building in which they are designed to ensure the technical equipment required internal environment. The proposal concerns the heating, ventilation, cooling, domestic hot water and lighting. At the end are attached graphic of energy performance certificates (PENB) and evaluated the economic and ecological point of view. The experiment deals with the measurement of the internal microclimate administrative building type in Brno, with regard to the requirements of current legislation of the Czech Republic.

Přidaná hodnota zelených střech / Added value of green roofs

Hrachovina, Vojtěch January 2017 (has links)
Introduction is focused on analyze green roof like a part of buiding construction, when thesis assembly principles of right proposal green roof layers. Main part describes characteristic properties green roofs at global impact. We get some added values after comparison with classic roof types. Master thesis consists of survey of added values of green roofs in these categories: life cycle assessment, microclima, outdoor climate, water retention. End of thesis devote to psychological effect of green roofs include questionnare about relationship between czech society and green roofs.

Návrh vzduchotechniky v bazénové hale / Design of air conditioning in the swimmingpool hall

Mahovská, Adriana Unknown Date (has links)
The diploma thesis is focused on the issue of ventilation of swimming halls. In the theoretical part, I assess the general issue of air quality in the indoor environment and in swimming halls, ventilation methods and elements for air conditioning in air handling units. In the project part, a complete design of air conditioning for the swimming pool buildings. For ventilation of the pool are created 2 alternative variants of dehumidification of the pool hall and their economic comparison. The experimental part is devoted to the evaporation of water from the water area when moving through water attractions.

Systémy TZB v nemovitých památkách / The systems of building services in immovable heritage

Maurerová, Lenka Unknown Date (has links)
The present PhD. thesis deals with the systems of building services (namely heating, ventilating and air conditioning, shading) which provide required indoor microclimate inside the immovable heritage. The work thus combines the exclusively technical field of building services (BS) and the general principles of heritage conservation. The aim of my PhD. thesis is the analysis of immovable heritage conservation processes, focusing on the current state of research and BS systems documentation. Furthermore the work concerns the possibilities of temporary measurements of indoor climate parameters inside the immovable heritage, and aims to develop a computer model (in BSim software) for the simulation of various working conditions in the selected buildings. For the stated aims were selected three representative historic houses: historical assembly hall at the Faculty of Civil Engineering, Brno University of Technology; the Palm Greenhouse at Lednice Chateau in Moravia; and Villa Tugendhat in Brno. These buildings had been surveyed for several years, and in this PhD. thesis I present their analysis, evaluation, and conclusions. The aims of this PhD. thesis broadly correspond to the transnational objectives. The present research is, for example, in accordance with the international document ICOMOS Charter (Zimbabwe, 2013) which is concerned with the analysis, conservation, and restoration of architectural heritage. The research of immovable heritage is also supported by European Union, e.g. by the Seventh Framework Programme of EU.

Vzduchotechnika hotelového komplexu / Air Conditioning of Hotel Komplex

Očkan, Tomáš January 2014 (has links)
The first part of the thesis is aimed on creating internal microclimate of the hotel complex by air conditioning systems. The choice of systems is based on theoretical knowledge’s and practical application in abroad. In the second part there is designed solution for hotel apartments and conference hall. The other areas are designed only conceptual. Technical solutions of chosen systems are the main outcome of the thesis. In the third part there are published my experimental measurements from laboratories of Oulu University of Applied Sciences. For the study field of Air Conditioning has been chosen Air Flow Measurement and Test Operation of HVAC unit. For the study field of Renewable Energy has been chosen the Heat Pump and for study field of Refrigeration has been chosen Water Cooling and Chiller Box.
