Cold production and trigeneration
Jordanov, Alexandr ; Toman, Filip (referee) ; Kracík, Petr (advisor)
This bachelor’s thesis is recherché dealing with cool production. The aim of this thesis is present the main cooling system, their comparison, practical realisations, describe laws, which should cooling systems accomplish and assess influence on the environment. The first two chapters are about cogeneration and trigeneration. The main part of the thesis is focused on different methods of cooling, their advantages, disadvantages and their influence on the environment. Because of refrigerants in cooling systems, which have negative impact on health and environment, is part of the thesis dealing with law. At the conclusion of the bachelor thesis is the assessment of cooling systems and their forward-looking perspective present.

Waste heat recovery from technological processes
Bednařík, Jakub ; Bača, Petr (referee) ; Vaněk, Jiří (advisor)
Master thesis deals with the utilization of waste heat from Nova Mosilana company. Theoretical part of this work is focused on the waste heat description (heat, heat quantity, heat temperature/quality, composition of waste stream) in which a considerable energy potential is hidden. The other parts describe waste heat technology, especially heat pumps, Organic Rankine Cycle (ORC) and system absorption cooling. Some of the technologies described in the theoretical part are used in the design of the more efficient existing waste heat utilization, especifically power and cold production.

Usage of Busbar as a Source of Heat
Svoboda, Ondřej ; Macháček, Jan (referee) ; Radil, Lukáš (advisor)
This study is dedicated to the use of heat energy from the busbar and its cooling system. The study deals with thermal analysis of the busbar, both using numerical simulations in SolidWorks and practical examination – warming of the busbar. We can verify the correctness of the simulation from the measured values. To determine the temperature profile of the busbar, it is necessary to measure the temperature at various points of the busbar by contact method using thermocouple or contactless method using a thermal imager. Measurements are performed at the busbar LIA1600 made by Siemens Busbar Trunking System Mohelnice. The aim of the study is to analyze temperature busbar, to suggest the most efficient method of heat recovery, and to make economic calculation

Solar cooling
Smokoň, Pavol ; Janírek, Martin Stanislav (referee) ; Hejčík, Jiří (advisor)
This bachelor‘s thesis deals with current possibilities of using solar energy to power cooling devices. First part is dedicated to various techniques used in the field of electrically driven and thermally driven coolers. Second part focuses on ways of getting solar energy to power them. Last part enlists examples of some installed solar cooling systems.

Trigeneration
Vítek, Stanislav ; Fortelný, Zdeněk (referee) ; Pospíšil, Jiří (advisor)
The aim of this thesis is present procedure and advantages of cogeneration and trigeneration. There are described primary cogeneration units which transform energy contained in fuel to required form of energy. Another part of the work deals with comparison of cooling technologies, namely vapour-cycle and absorption cycles. At the conclusion of the bachelor thesis, the economic assessment is present for all considered for cooling systems with reference to durability of the system.

Trigeneration
Hadraba, Jiří ; Chroboczek, Libor (referee) ; Fortelný, Zdeněk (advisor)
This bachelor thesis is the recherche dealing with cogeneration and trigeneration consecutively. There are described prevailing primary units designated to the transformation of the energy of the fuel in cogeneration units to electricity and heat. The next chapters are dedicated to the absorbing and compression machine cooling. There are also analysed the possibilities of the heat accumulation and the influence of trigeneration on the enviroment.
