Air conditioning in the library
Pospíšilová, Lucie ; Uher, Pavel (referee) ; Blasinski, Petr (advisor)
Dissertation offers a plan for air – conditioning equipment of library building in Brno and it involves air filter experimental measurement. The proposal is divided into three parts. The first part explains air filter theory with detailed description of atmospheric air filters for separation of particles for general ventilation - filter parameter determination. Theory part ends specifically with pocket air filters and their construction. The second part focuses on experimental pocket air filter measurement execution, which calculates with variable filter cartridges and pocket count. Measurement also evaluates pressure drop and their efficiency. The last part of the dissertation looks at air – conditioning equipment design for specified building, concretely library building. The project solves fresh air traffic into interior of selected library rooms and it counts with thermal heat gain in summer season, heat loss in winter season and air humidity modification.

Interiors of small and medium enterprises as a source of waste heat for a heat pump
Valachovič, Filip ; Miklas, Václav (referee) ; Máša, Vítězslav (advisor)
Environmental problems and the recent high rise in energy prices are forcing us to look for more sophisticated and more energy-efficient solutions. As a result, more and more renewable energy sources and waste heat are being used. Sources of waste heat, which have so far remained outside the area of interest, such as waste heat contained in the air of industrial interiors, are thus becoming the subject of interest. This waste heat undoubtedly has huge potential in many industries. The use of waste heat is always complemented by a certain technology. In terms of operating costs and the environment, the heat pump seems to be a perspective solution. The main goal of the presented thesis is to evaluate the application potential of heat pumps for the use of waste heat contained in the air of the interiors of small and medium enterprises. The first part deals with an overview of available technologies for the use of waste heat, introduction to heat pump technology, the issue of heat load of industrial buildings and due to the possibility of using a heat pump for cooling the interior, attention is also paid to hygienic requirements for the quality of the interior. The second part of the work presents a conceptual design of the integration of the heat pump into the selected process – laundry facility. The methodology of the solution consists of the selection and analysis of the process in terms of heat energy, heat pump design, economic analysis, and evaluation of the achieved results. The currently available waste heat in the air of the examined laundry corresponds to 37 kJ and the heat load corresponds to the heat output of 526 kW. The minimum heat output of the heat pump for heating 4.3 m3 of water per hour corresponds to 170 kW at a compressor electrical input of approximately 23 kW. This parameters, current energy prices, an estimated investment of CZK 1.5 million and compared to water heating by natural gas combustion give a payback return in less than 6 months. Given the current energy prices, it can be stated that the heat pump is the optimal solution in this case. It is surprising that no work on this topic has been created yet and it can be stated that the diploma thesis presents a completely unique solution with a high potential not only in the laundry process.

Air conditioning area of the car showroom
Svobodová, Leona ; Blasinski, Petr (referee) ; Rubina, Aleš (advisor)
The diploma thesis deals with shielding elements in the theoretical, project and experimental level. The theoretical part describes the variants of building shading and compares individual shading elements. It explains several concepts from the field of environmental technology, which are related to the topic. The design part deals with the air conditioning of the showroom space with a specific indoor environment. The space has a flush facade, so it has a high heat load. This is a showroom for veterans, where it is necessary to maintain optimal constant hu-midity throughout the year. An air conditioning unit was designed for these needs. The experimental part describes the measurement of the values of the shielding factor of external blinds for individual slopes of slats. The measurement results are applied to the reference room and the dependence between the inclination of the slats and the energy demand for space cooling is evaluated by the software.
