Design of ventilation and cooling in a two-family house
Exnerová, Anežka ; Charvát, Pavel (referee) ; Pech, Ondřej (advisor)
This diploma thesis deals with ventilation and cooling systems in two-generation family house. It is divided into two parts – theoretical and practical. Theoretical part describes basic terms and laws needed for subsequent solutions. The principle of ventilation and cooling, parts of air-handling units, air duct and distribution elements are presented. The thesis continues with calculations and device design. First, the selected object is described in aspects of construction and considered parameters. The amount of ventilation air is proposed, followed by the design of air handling units, piping and distribution components. Furthermore, there is the calculation of the thermal load of the attic apartment because there is a requirement for cooling. At the end of the thesis, implementation and operating costs are evaluated.

Air conditioning design in the theater
Vladyková, Pavlína ; Rubinová, Olga (referee) ; Blasinski, Petr (advisor)
The aim of the work is to design an air conditioning system for the auditorium and stage of the theatre that will cover the heat gains and partly the losses. The work is divided into three parts - theoretical, computational and design. The first part deals with the carbon dioxide concentration in the interior. The second part contains all the necessary calculations and design of the air conditioning system in the theatre. The third part is practical - it contains the technical report, technical specification, and control scheme. Drawings of the proposed air conditioning system are also part of this work. The procedure has been carried out in accordance with the applicable standards and guidelines

Optimization of air conditioning of the ice stadium
Zach, Daniel ; Rubinová, Olga (referee) ; Blasinski, Petr (advisor)
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.

Air conditioning of the cinema
Czempka, David ; Rubinová, Olga (referee) ; Blasinski, Petr (advisor)
The aim of this bachelor thesis was to design air-conditioning systems in the selected cinema equipped with a spacious foyer with bar, cinema hall with technical facilities, recording studio and secondary spaces. Systems are designed to meet hygienic, operational and safety requirements and to create an optimal indoor microclimate for people. The air-conditioning systems provide distribution of fresh air and extract of exhaust air, covering the heat loss in winter and heat gains in summer, and in selected spaces also humidification in the winter season. In the theoretical part of the thesis, I focused on the basic acoustic quantities and spatial acoustics.

Design of Cooling and ventilation system in family house
Bíza, Michal ; Charvát, Pavel (referee) ; Pech, Ondřej (advisor)
The diploma thesis is focused on the design of ventilation and cooling for the family house. The first part of the thesis deals with possibilities of ventilation and cooling, air ducts and their components and selected ventilation units. The next part deals with the analysis of air-conditioning routes, their dimensions and pressure losses. Then the heat gain is determined, and cooling is proposed. The last part deals with the comparison of financial costs for purchase of all components for ventilation and cooling, assembly, installation and operating costs. The enclosed drawings and item lists are at the end of the thesis.

Bioreactor monitoring and control for optimal heat gain
Hujňák, Jan ; Bajko, Jaroslav (referee) ; Baxant, Petr (advisor)
This bachelor thesis deals with thermal energy generation in biodegradation processes, monitoring and control of these processes. In the theoretical part, it gives a brief overview of biodegradation processes, then focuses only on processes in which waste heat is produced. Mainly it focuses on the composting process, its stage, the ideal composition of the composting material, the composting methods, the control quantities and the metering devices. The practical part focuses on the improvement of the original bioreactor and the subsequent realization of the new bioreactor. The bioreactor is subsequently monitored using temperature sensors that describe the ongoing processes inside the compost using measured temperatures. The aim of the bachelor thesis is to connect the bioreactor with yurt, to realize thermal circulation and to control this circulation through the AMiNi system in order to achieve optimal heat recovery without negative effects on the course of biodegradation processes inside the bioreactor.

Air-conditioning of office rooms
Taclík, Jakub ; Toma, Róbert (referee) ; Fišer, Jan (advisor)
The aim of this diploma thesis is to design the air conditioning system for one floor of the offices. The thesis is divided into theoretical, computational and design part. The computational part consists in determining the amount of ventilation air, calculation of heat losses, heat gains and psychrometric calculations for summer and winter season. Based on the calculated values, air ducts, end-points and air-conditioning units are designed. The diploma thesis is supplemented with a list of materials and drawing documentation.

Airconditioning of the passive house
Voleš, Jakub ; Uher, Pavel (referee) ; Rubina, Aleš (advisor)
The aim of this bachelor´s thesis is the concept of the air-conditioning and cooling system for the residential rooms of the two-storeyed house. The technical solution respects functional, hygienic and operational demands on the internal microclimate. The main functional requirement of the air-conditioning system is compensation of the heat losses and the annual inflow of the necessary minimum of the fresh air. The theoretical part of the thesis is concerned about acoustics and it’s connection with air-conditioning. Firstly, the text introduces what is sound from the physical point of view, characteristics and it’s impact on the physiology of the humans. At the end of the theoretical part are mentioned the sources of sound and it’s spreading through the system. Finally, the methods leading to the reduction in harming acoustics effects are presented. The result of the computational part is the design of the air-conditioning unit, the piping and the other components; also the concept of the direct cooling at the summer period. The project part containes the technical report, the attachements and the project documentation for realization.

Air-conditioning system of a typical floor of A1 building
Pekárek, Antonín ; Charvát, Pavel (referee) ; Krejčí, Vladimír (advisor)
Master thesis deals with designing of air-conditioning system into newly reconstructed high-rise building of Faculty of Mechanical Engineering Brno University of Technology. Reconstruction of a building results in change of thermo-technical parameters which impacts dimensioning of air condition system. Designing air-conditioning system depends on heat loss and heat gain calculation and also on consequential psychometrical calculations. The size of air conditioning equipment which provides required internal microclimate will be determined from the calculation results. Currently there is Detail design elaborated including technical report and material specification.
