Thermal measurement
Zachar, Martin ; Lisý, Martin (referee) ; Kracík, Petr (advisor)
This thesis deals with theory of thermal measurement with both physical as well as technical side. Thesis describes basic methodics of thermal measurment and further compares few different thermographic cameras at the current market. Main part of the thesis is focusing on a script, that has been created in program Matlab, serving for analysis of a series of thermographic pictures capturing verticaly placed pipes, following by registration of founded temperatures to Excel and drawing of diagrams of the change of average temperature along pipe and histograms of temperatures of given pictures.

Super-heated steam cycles
Uherek, Jan ; Kracík, Petr (referee) ; Pospíšil, Jiří (advisor)
The purpose of this bachelor´s thesis is to present new, highly efficient thermal cycles used in power plants, and to compare them with classical cycles. First, the impact of these cycles on the efficiency of electricity production is examined. The following section describes power plants where the supercritical technology has been successfully installed. The last section explains the calculation of the heat transfer surface. The conclusion of this thesis attempts to outline the future of energetics from the author´s point of view.

Energy use of biomass
Holečková, Michaela ; Kracík, Petr (referee) ; Baláš, Marek (advisor)
The aim of this bachelor thesis is the research of different types of biomass, description of the various types of methods and technologies for energy usage of biomass and the mapping of large power plant units in the Czech Republic. The first part of this thesis deals with the definition of biomass, its distribution and the description of basic essential attributes describing its composition. The downstream part of this work is focused on the technologies of gaining energy out of biomass or its possible conversion into other products depending on the currently discussed type of technology. The last part deals with energy balances of biomass in the Czech Republic and focuses on individual companies who use biomass as an energy source, by applying one of the methods mentioned in the previous part.

Production of cold
Soľár, Slavomír ; Šnajdárek, Ladislav (referee) ; Kracík, Petr (advisor)
This bachelor thesis is focused on description of cool production and properties of two basic cooling units. There are also included calculations for comparing these two units in term of consumption and operating expenses. Part of labour is devoted to applications of units in Czech Republic and rest of World, where the system of district cooling is used. It is also important to acquaint with legislation and regulations, which are related with production of cool and manipulation with equipments and refrigerants.

Heat pumps for heating and hot service water preparation
Valášek, Martin ; Hrnčířová, Michaela (referee) ; Kracík, Petr (advisor)
This bachelor’s thesis is aimed to describe heating and water warming in the detached houses by basic technical devices and there are suggested various types of heat pumps for a particular object. These heat pumps are compared technically and economically. In the beginning of the thesis there is a summary of the possible ways of the house heating and water warming systems, such as heating by electric power, by gas, by solid fuel or the centrally distributed heating. Then the thesis concentrates on heat pumps. There are described various types of heat pumps, also their advantages and disadvantages. There were chosen four main types of heat pumps – air/water, air/air, water/water and earth/water – and with each type there’s constructed a plan for a low-energy house heating. This house is located in Vyškov and there’s thermal loss of 6 kWh and water-warming of a capacity of 260 l per day. At last there were used economical calculations, which shown, that the water/water heat pump has the shortest return rate in comparison with a gas-using heating system – 5 years. Considering the lifespan of the heat pumps – 10-20 years – all the heat pumps are profitable except for the air/air heat pump. The investment in this heat pump doesn’t return.
