Variant solutions reconstruction of airconditioning systems in the laboratory
Faltys, Michal ; Andrys, Petr (referee) ; Rubina, Aleš (advisor)
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.

Creating a microclimate of an industrial building with high demands on its uniformity
Tůmová, Eliška ; Gebauer, Günter (referee) ; Šikula, Ondřej (advisor)
This diploma thesis deals with the optimization of microclimate of an industrial building. There is required constant temperature with minimal fluctuations during manufacturing process in the building. Due to insufficient cooling power of air-conditioning system was objective to design a solution that ensures stability of internal temperature during production especially in summer and simultaneously should be the solution economically acceptable. Simulation shows original state defined problems. Some new or unusual materials for solar shading are reviewed in the thesis by the experimental measurements and by the comparative method. To each material is assigned shading coefficient according to Czech standards, thereby is achieved universality for calculations of heat gains resulting from solar radiation. By one part of the experiments and their evaluation is determined thickness of the standard single glass glazing. It is also determined proportional transmittance of solar radiation for certain multiwall polycarbonates, which are currently used as fillers of industrial skylights and production hall‘s window openings. From experiments resulting design is subjected to the simulation. Comparison of temperatures is shown for the time before the installation of designed solar shading and after the installation of the solar shading.

Air Conditioning of Hotel Komplex
Očkan, Tomáš ; Děckuláček, Zbyněk (referee) ; Gebauer, Günter (advisor)
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.

Cooling systems and their management in office settings
Kotásek, Petr ; Šikula, Ondřej (referee) ; Formánek, Marian (advisor)
The bachelor thesis deals with the cooling systems of office spaces. The theoretical part focuses on the principle of operation of commonly used cooling systems and the possibility of cold production. This work describes the advantages and disadvantages of each system. The result of the calculation is design of optimal cooling system for the office building, which secures the removing of the heat load in the summer.

Airconditioning of production and storage hall
Fridrich, Lukáš ; Ell, Jiří (referee) ; Rubina, Aleš (advisor)
The bachelor thesis deals with the design of air conditioning equipment for production and storage hall and the space necessary to ensure the operation. The first system is designed to be able to cover the thermal load operated rooms in summer and hot air ventilation in winter time. The second system is used to hot-air heating in winter time and cover the thermal load in the summer. The third system provides coverage of thermal load in the preparation room. The theoretical part focuses on the rooftop units.

Hot water heating civil buildings
Vecheta, Aleš ; Počinková, Marcela (referee) ; Horák, Petr (advisor)
The main goal of this thesis is to design heating and warming of a TV in civil building. It is a building with overall built up area of 410.44 m2 which has two above-ground floors and under some parts of the building is a cellar. Heating is mainly delivered by heating units with local source of heat. Water in the pool uses warming with the help of a heat exchanger connected to a source of heat. The theoretical part is focused on the heat. There are described basic portion of the hinge and condensing boilers. Combustion principle and the principle of participation.

Microclimatic conditions in train, public city transport and long distance transport driver´s cabins
VÍT, Zbyněk
In my paper I´ve intended to collect theoretical knowledge of the issue of microclimatic conditions in the workplace and it´s impact on health and performance of the worker with the scope to workplaces ? cabins of train, city public transport and long distance transport drivers. I have proceeded from legally binding regulations. In the theoretical part I have described particular requirements and limits of factors affecting the quality of the inner workplace environment. After the theoretical part I have dealt with the practical part where I have proceeded from measurements which I have attended personally. I have completed my own measurements with the results of other measurement records elaborated by State Health Institute in Prague. Perspective measurements were interesting due to the ways technical devices were working and set to provide optimum microclimatic conditions in workplace. The largest measurement results were those from electric train units, known in our railway transport system as ?Pendolino?. While in the workplaces of engine drivers the set year-long inner environment limits have been mainly implemented, in the driver workplaces of public city and long distance transport, summer outside conditions had an impact on significant worsening of the microclimatic conditions ? a big temperature load on drivers, which is impossible to be eliminated without financially demanding measures.
