Air condition of lodging house
Horká, Lucie ; Rubinová, Olga (referee) ; Šikula, Ondřej (advisor)
This bachelor's thesis deals with the air condition of the lodging house. Design is specialy focused on guest rooms, common areas and the apartment of manager. The project deals with ventilation units, including heat recovery, chillers and the heat source. Designed facilities in the lodging house have achieved the optimum microclimate in the summer and also in the winter.

Controlled dehumidification in summer season
Voleš, Jakub ; Ell, Jiří (referee) ; Rubina, Aleš (advisor)
The subject of the diploma thesis is the design and the assessment of two variants of existing HVAC system, that serves the microelectronic laboratory premises of GL Electronic company, which are situated in JIC INMEC center. The aim of the designing process is to find the optimal solution of the problem, which is concerned of excessive air humidity gains in the clean rooms. The first proposed approach is the installation of controlled dehumidification in the form of direct cooling into the yet existing device. The second considered approach is a complete deconstruction of implemented air conditioning unit and subsequent reinstalling of the brand new unit, which would meet all the requirements. Both two variants will be in the beginning outlined in a form of pre-study, selected option will be later on processed as project documentation for construction. The winning solution will be designed in the way that will satisfie the criteria of hygiene, function, and economy. The next section of the text will be dedicated to the research regarding the topic of the physical nature of air humidity, of the transportation of humidity, dehumidification of the space, also. Last but not least, the heat recovery efficiency will be measured (in the form of thermal glycol tubes). The experiment provides evidence of the system's real-time performance.

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.

Ventilation of the roadhouse
Kojecká, Karolína ; Uher, Pavel (referee) ; Rubinová, Olga (advisor)
The bachelor thesis deals with the design of ventilation and direct cooling in the roadhouse. The ventilation system provides supply of fresh air and delivery of exhausted air. In selected rooms is resigned direct cooling to remove the heat load and provide a suitable microclimate in the summer.

Industrial cooling systems
Doležal, Jan ; Horák, Petr (referee) ; Formánek, Marian (advisor)
This thesis describes the design of cooling ice rink. Cooling system design is based on a physical nature, measured data and observations from practice. The result is a proposal cooling system with the highest possible cooling factor, which uses waste heat for technology needs snow pit and hot water, in order to achieve the lowest cost of operation ice rink.

Application of modern technologies to increase the life of forming tools
Bambušek, Martin ; Sliwková, Petra (referee) ; Píška, Miroslav (advisor)
The content of this thesis is to design and analyze possible ways of cooling hot forming tools and holders with use of modern and conventional technologies. From this analysis a least technologically and economically difficult solution with high efficiency of cooling effect is chosen and used on specific application. There are also described heat effects on degradation in the beginning of this thesis. Cutting edge of the tool made by the chosen technological solution is also analyzed during the experiment. In the conclusion of this thesis is an evaluation of achieved results.
