Energy usage of beer production
Maťa, Jakub ; Tuhovčák, Ján (referee) ; Hejčík, Jiří (advisor)
The bachelor thesis deals with the issue of energy consumption of beer production. The first part focuses on the technology of beer production itself, the understanding of which is a key prerequisite for assessing the possibility of using a heat pump for this process. The main part then describes the individual processes and their energy consumption. Finally, it evaluates the use of a heat pump and shows if it could reduce the energy requirements of beer production.

Interiors of small and medium enterprises as a source of waste heat for a heat pump
Valachovič, Filip ; Miklas, Václav (referee) ; Máša, Vítězslav (advisor)
Environmental problems and the recent high rise in energy prices are forcing us to look for more sophisticated and more energy-efficient solutions. As a result, more and more renewable energy sources and waste heat are being used. Sources of waste heat, which have so far remained outside the area of interest, such as waste heat contained in the air of industrial interiors, are thus becoming the subject of interest. This waste heat undoubtedly has huge potential in many industries. The use of waste heat is always complemented by a certain technology. In terms of operating costs and the environment, the heat pump seems to be a perspective solution. The main goal of the presented thesis is to evaluate the application potential of heat pumps for the use of waste heat contained in the air of the interiors of small and medium enterprises. The first part deals with an overview of available technologies for the use of waste heat, introduction to heat pump technology, the issue of heat load of industrial buildings and due to the possibility of using a heat pump for cooling the interior, attention is also paid to hygienic requirements for the quality of the interior. The second part of the work presents a conceptual design of the integration of the heat pump into the selected process – laundry facility. The methodology of the solution consists of the selection and analysis of the process in terms of heat energy, heat pump design, economic analysis, and evaluation of the achieved results. The currently available waste heat in the air of the examined laundry corresponds to 37 kJ and the heat load corresponds to the heat output of 526 kW. The minimum heat output of the heat pump for heating 4.3 m3 of water per hour corresponds to 170 kW at a compressor electrical input of approximately 23 kW. This parameters, current energy prices, an estimated investment of CZK 1.5 million and compared to water heating by natural gas combustion give a payback return in less than 6 months. Given the current energy prices, it can be stated that the heat pump is the optimal solution in this case. It is surprising that no work on this topic has been created yet and it can be stated that the diploma thesis presents a completely unique solution with a high potential not only in the laundry process.

Using a heat pump
Tretera, Robin ; Křivík, Petr (referee) ; Jandová, Kristýna (advisor)
This diploma thesis provides basic information about the thermal pumps and photovoltaic systems. The heat pumps are described regarding their construction and sources of low potential heat. The description of photovoltaic systems explains the main principle of transformation the solar light to electric power and possible cooperation of this systems with the heat pumps. In practical part of the thesis there is a description of the assessed building and calculation of its thermal losses. It is followed by three designs of the thermal pump systems which are supposed to replace the original way of heating - the electric boiler. One of the designs is supported by photovoltaic system. The final part of the thesis provides the calculation of required heat sources for house and water heating, the operation expanses of all three heat pump designs, prices of electric energy and economical reliability of described solutions.

Utilization of waste heat from rectification
Frank, Vojtěch ; Konečná, Eva (referee) ; Touš, Michal (advisor)
The purpose of the thesis is to draw up a model of the energy and material balance using technical and technological analysis of the current state of production of waste heat in the process of distillation. Using these results, subsequently evaluate the energy potential of individual streams and propose optimal energy savings using waste heat. Emphasis is placed on the modelling of the process and the various proposed savings options. The result is also an evaluation of the potential of the proposed savings based on the results of the calculation.

Low temperature heating with heat pumps
Bros, Miroslav ; Horká, Lucie (referee) ; Počinková, Marcela (advisor)
The master’s thesis deals with design and comparison of two variants of low temperature heating with radiant systems and heat pumps. Building is used for administrative purposes. The theoretical part describes the evaluation of heat pumps. The calculation part deals with the calculation of heat loss of the building, the design of the heating system, the hot water preparation system, the heat source, all necessary supplementary devices, and the calculation of yearly heat and fuel consumption for heating and hot water preparation of the building. Heating system consists of floor heating and ceiling heating. For hot water preparation an indirect fired hot water storage tank is designed. The source of heat is a cascade of two air/water heat pumps. Experimental part is focused on measuring and assessment of pressure loss, heat output and efficiency of radiant ceiling panel.

Energy optimization of the administrative building
Černý, Tomáš ; Horák, Petr (referee) ; Adam, Pavel (advisor)
The diploma thesis deals with the energy audit of administrative building. In the theoretical part I described the heat pumps. In a calculated part I proposed austerity measures and created of them saving variant. I chose the most suitable variant and assess it from an economic and ecological point of view. In the third part, I use the calculation program to optimize the building.

Domestic heat pumps
Merta, Libor ; Lisý, Martin (referee) ; Pospíšil, Jiří (advisor)
The Bachelor´s Thesis deals with domestic heat pumps. It is devided into two basic parts. In the first part, an operating principle, components and various types are described. Particular kinds of low-energy sources including characteristical features and comparision are mentioned there as well. In the second part, a project for a domestic heat pump is prepared. The project includes proposition of a particular heat pump, a borehole and an amount of heat needed for heating and a preparation of warm water. At the end, a complete economical balance including an economic return of the investment is mentioned.
