Design optimization of packed bed for thermal energy storage
Krist, Thomas ; Charvát, Pavel (referee) ; Klimeš, Lubomír (advisor)
Tato diplomová práce se zabývá tématem výměny tepla v zásobníku tepla typu ”packed bed”. Cílem je popsat přenos tepla v zásobníku tepla obsahující kamínky malých průměrů, skrz který proudí horký vzduch. Toto je modelováno v prostředí MATLAB. Na začátku je krátký úvod do problematiky zahrnující ukládání tepla a jeho možné využití. Dále je uveden krátký přehled o základech přenosu tepla, typech přenosu tepla a termofyzikální vlastnosti systému vzduch-kámen. Ve třetí kapitole je představen zásobník tepla typu ”packed bed” a rozličné modely a dané podmínky jsou vysvětleny. Další kapitola se zabývá s numerickými metodami, převážně s metodou konečných diferencí použitou v této práci. Pátá kapitola se zaměřuje na obecnou optimalizaci daného problému přenosu tepla. Populačně založený metaheuristický optimalizační algoritmus zvaný Genetický algoritmus je popsán. Sestavení modelu je ukázáno v šesté kapitole, stejně jako prezentace výsledků získaných z programu MATLAB. V poslední kapitole je pak diskutován závěr a doporučení.

Creation of laboratory tasks for Selected topics from renewable energy sources and energy storage
Vaněček, Lukáš ; Vaněk, Jiří (referee) ; Bača, Petr (advisor)
This master‘s thesis contains a comprehensive laboratory task about saving a heat energy with a use of changing a state of matter. The thesis is written for the object Chosen passages of renewable resources and saving a heat energy. Part one presents a theoretical part of the topic, terminology and relations needed to make this laboratory work. It also contains a created procedure of partial tasks necessary to take laboratory measurements. The second part of the thesis is about measuring and evaluation of acquired values according to procedure described in the theoretical part of the thesis. Different variations considered during the creation of measuring procedure are also named here. The final part of the thesis describes a laboratory equipment necessary to complete the task and an example of filled protocol is attached.

Hot air airconditioning of the flat house
Viktorin, Michal ; Tesař, Zdeněk (referee) ; Rubina, Aleš (advisor)
The brachelor's dissertation is divided into three parts: theoretical, computational and design. The theoretical part is focused on heat recovery systems in air through regenerative heat exchangers. The calculation and project part deal with the design of air ventilation in flat house. The building is used for permanent housing and is divided into thirteen functional units. A technical solution is developer with regard to the statutory hygiene parameters of air and thermal comfort microclimate under applicable legislation of the Czech Republic in 2015. In addition, it will provide the ideal microclimate for housing and improve the quality of life in the building.

Airconditioning of intensive care unit
Cakl, Dominik ; Blasinski, Petr (referee) ; Rubina, Aleš (advisor)
This bachelor´s thesis deals with design of air-conditioning and air-condition systems in the spaces of intensive care unit of infection department and employees department. Proposoal of the systems meets relevant standarts, hygiene and operating requirements. The computational part is focused on total object analysis, heat balance, air flow in relation to increased hygiene requirements and requirements for air heating. The computational part also involves distribution, adjustment of air and other proposals, which are integrated in correctly proposed equipment. The theoretical part is involving heat recovery with heat pump. The project is processed on the level of the project implementing.
