The field of a research of this diploma thesis is building with controlled internal temperature. The research is focused on main heat fluxes at this type of buildings and how it contributes to the energy consumption of the building. The main objective of the analysis is heat loss caused by heat flux through the building envelope and air exchange at the building. As next it is described heat gain resulting from the operation inside of the building. To obtain the results of the research part is used software on the platform Delphi Pascal, temporarily called SIM_Chlad. The aim of this computer modeling is non-stationary heat fluxes from the mentioned heat sources in the building. The computed heat balance analyzes the energy consumption of the building for a period of one year. The diploma thesis evaluates impacts reflecting local weather conditions, the structural system of the building and the operation in the building. A cooling machinery analysis is not the subject of the research at this diploma thesis.

The aim of the thesis "Design and optimization of the heat pump" is the project documentation for building permits, finding a suitable source of heat and cold. The problem is solved for a Tesco hypermarket. The device is designed to meet the health, performance and functional requirements for indoor climate. The task of this device is to transport fresh air into the interior cover heat losses in winter and coverage heat gains during the summer. The theoretical part deals with the problem of heat pumps. Special mention is about heat pump air x air. Calculation and design part is a specific proposal, two air conditioners and optimizing for winter. The experimental part deals with the processing of data on existing rooftop units.

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.

The diploma thesis deals deals with the designing and assessment of the two variants of cooling and humidifying the air in the production hall for cotton in Humpolec. The system is proposed to fulfil hygienic, operational, economic and functional requirements for indoor microclimate of the production hall. The task of this system is the transport of cooler air to interior and the covering of heat gains all year round. The equipment is also designed for the regulation of air humidity in the interior. The theoretical part is devoted to air humidification and air humidification device. Calculation of the project and then a specific proposal, two variants for air distribution level studies. Both variants are treated as project documentation. Experimental part is devoted to the measurement on the measuring path containing adiabatic humidifier in the laboratory. The benefit of the experiment is to verify the data from the manufacturer adiabatic humidifier which we can assess the practical use of the product.

The aim of this master thesis is to design a low-energy building for civic amenities, specifically the design of a recreational wellness centre. The building has an L-shaped floor plan with a flat roof and is designed with two above ground and one underground floor. The ground floor will serve as a wellness centre with a swimming pool and saunas. Massages and solariums are proposed on the 2nd floor. Technical facilities are located in the basement. The first part of the thesis is devoted to the architectural and structural design. Structurally, the building is divided into two parts. The part of the administrative facilities and the massage rooms consists of a construction of the character of a transverse wall system made of cut brick blocks and insulated with ETICS. The internal masonry is designed in ceramic ground bricks. Ceiling structures are in the form of continuous reinforced concrete slab. The building is based on footings and waist foundations. The roof of the building is single-skin flat with a gravel. The wellness part is made up of a monolithic diaphragm skeleton with high slenderness columns. The horizontal load-bearing structure in this case again consists of a continuous monolithic reinforced concrete slab. The second part of the thesis deals mainly with the environmental engineering of the buildings. The building will be heated by a pellet boiler and will also use energy from photovoltaic panels. Ventilation in the building is provided by air handling units with heat recovery. The third part of the thesis deals with the assessment of solar gains in the indoor environment of the pool hall. Three variants are proposed with multi-criteria evaluation and the optimal option is selected. The thesis is mainly elaborated in Archicad, Deksoft, MS Excel and Word software.

This diploma thesis is divided into three parts: theoretical, calculation and experimental measurement. The issue of humid air and air-conditioning in winter stadiums is elaborately analysed in the theoretical part. In the calculation part, the dessertation focuses on the optimization of current draft of hockey hall air conditioning system. The hall is now in operation during the season, which means from September to March. In the dissertation are discussed two variants of the draft. The first variant is draft upgrade to year-round operation with condensing dehumidification. The second option is solved as a combination of air handler unit system and absorption dehumidification. This variant is also designed for seasonal and year-round operation of the ice rink. At the end of the dissertation are all of them compared in terms of annual costs. The experimental measurement is carried out on dehumidification of air from areas with high water gains, in this case swimming pool hall model. This problematics is solved by changing the speed of ventilator and using Peltier generator.
