Use of surface water as a low-temperature source for heat pumps
Jordanov, Alexandr ; Špiláček, Michal (referee) ; Pospíšil, Jiří (advisor)
First part of my diploma thesis contains research of ground water, refrigerants and heat pump including its inner components. Second part contains calculation of heat exchanger water – antifreeze, which use heat from a river and it will be used for input to heat pump water – water.
High temperature energy storage
Roden, Lukáš ; Špiláček, Michal (referee) ; Pospíšil, Jiří (advisor)
Because of an increase share of renewable energy, there is a need to develop energy storage technologies, whether it is the electricity or the heat one. The main goal of this thesis is to design and assess a high temperature energy storage used for a long-term accumulation of a thermal energy. The designed storage is calculated for the needs of a family house with photovoltaic panels. It is used numerical method in the Excel software to simulate behaviour in storage. One of the biggest lack is a storage is large number of tubes, which are needed for a heat delivery into and out of the storage. This and the other related lacks make it impossible to a cost-effective application without the appropriate modifications.
Industrial heat pump
Pinkas, Marek ; Špiláček, Michal (referee) ; Pospíšil, Jiří (advisor)
The diploma thesis deals with the issue of industrial heat pumps. Its aim is to describe the technologies of heat pumps and their use in industry, where they are already often used to recover waste heat. The work is devoted to compressor and absorption heat pumps. The main parts of the heat pump are presented and described here. Emphasis is also placed on the working materials used. Real applications of industrial heat pumps are also presented. At the end, two variants of the application of the heat pump in cooperation with the cogeneration unit are proposed. In the first case, a compressor heat pump was proposed, and in the second, an absorption heat pump. The heat source for the heat pump is water from the wastewater treatment plant.
Heat exchanger for waste heat utilization
Švach, Šimon ; Brázdil, Marian (referee) ; Špiláček, Michal (advisor)
This bachelor thesis deals with waste heat recovery using a heat exchanger. The aim of the thesis was to design a heat exchanger for the recovery of hot water from the cooling of a concentrator photovoltaic panel. The thesis is divided into theoretical and practical parts. In the theoretical part, a literature research on heat recovery and photovoltaics was carried out. In the practical part, a heat exchanger has been designed for a specific solution.
Nuclear power plants
Krakovský, Matej ; Špiláček, Michal (referee) ; Milčák, Pavel (advisor)
The bachelor´s thesis explains different types of nuclear reactors and their fuel and safety characteristics. The thesis is complemented with history and description of nuclear powerplants in Slovakia. There are mentioned some of the experimental projects, whose usage is expected in the future. In the beginning are described fundamentals of nuclear energetics and nuclear fission chain reactions.
Cooperation of gas boiler and heat pump in the heating system
Kunert, Šimon ; Špiláček, Michal (referee) ; Pospíšil, Jiří (advisor)
This master’s thesis deals with the cooperation of gas boiler and heat pump in heating system. It contains a brief description of both device and hybrid variant. The aim of this thesis is to create a balance model that helps primary monitor the released CO2 emission and operating costs. The subsequent parametric study seeks the optimal setting of cooperation for both monitored parameters. The results are compared with gas boiler heating or heat pump air to water. The last part is developed to find the optimal setting for a particular object.
Gravitational energy storage
Militký, Ondřej ; Špiláček, Michal (referee) ; Pospíšil, Jiří (advisor)
This thesis characterizes the most common systems for storing electricity, including principles, stages of development and major installations. The thesis is mainly focused on the issue of gravity storage of electricity. The construction of individual types of storages, the phases in which individual projects are right now and their expected development are described here. Part of the thesis is the design of a gravity storage model showing the principle of operation and verification of the possibility of producing a small energy storage in home conditions. Furthermore, the energy and economic possibilities of installing a home gravity storage of energy and a gravity storage on an industrial scale are assessed.
Reactors and heat exchangers using liquid metals
Kmoníček, Jiří ; Špiláček, Michal (referee) ; Šnajdárek, Ladislav (advisor)
This bachelor thesis deals with nuclear reactors using liquid metals and heat exchangers used in nuclear power plants. Furthermore, a thermal calculation is performed for the selected steam generator. The drawing documentation of selected parts is also included.
Flue gas - water heat exchanger design 2020
Pálka, Jaroslav ; Baláš, Marek (referee) ; Špiláček, Michal (advisor)
The aim of this final thesis is to design flue gas – water heat exchanger with certain power and entering temperatures. This heat exchanger is designed for a gas boiler. From over-view of suitable technologies was selected gasketed plate heat exchanger. Design consists of heat, pressure drop calculation and basic design drawing.
Design of the steam generator for a nuclear power plant
Hort, Lukáš ; Špiláček, Michal (referee) ; Milčák, Pavel (advisor)
This bachelor's thesis is about the design of a steam generator for a nuclear power plant. The opening chapters are purely theoretical, with the first one covering nuclear energy as such, the next one continuing with the search for different types of parogenerators and their subsequent comparison. This is followed by a calculation section dealing with the thermal calculation of the parogenerator for the given parameters.
