Surface condenser
Kloda, Michal ; Baláš, Marek (referee) ; Šnajdárek, Ladislav (advisor)
The bachelor’s thesis dealing with surface condensers is split into three main sections. The first section describes surface condenser, problems of heat transfer during condensation and a method of determining the heat transfer coefficient using the methods HEI and VTI-CKTI. The second section deals with the main construction elements and their materials, where the special attantion is paid to condenser tubes materials. In the third and the last section, the simplified thermodynamic design of surface condenser for given parameters is shown.

Steam ejector pump
Třináctý, Jan ; Baláš, Marek (referee) ; Šnajdárek, Ladislav (advisor)
The aim of this theses is to do search about maintaining vaccum in surface condensors and subsequently propose basic dimension of one stage steam ejector. The first part deals with the issue of vacuum. The following part is dedicated to description of various types of vacuum pumps. Hence it describes the principle of operation of each pump as well as their output. The following part deals with vacuum and vacuum technology in the field of power engineering. This part is dedicated to those types of vacuum pumps that are used in power engineering, especially to steam ejectors which are most widely used. The final part is addressed to the design of single stage steam ejector. This part contains the calculation of pump dimension. The conclusion evaluates the design of one stage steam ejector.

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.

Brown Coal Power Plants in Czech Republic
Šperka, Radim ; Šnajdárek, Ladislav (referee) ; Špiláček, Michal (advisor)
The thesis describes brown-coal power plants in the Czech Republic. The first part discusses brown coal as a mineral raw material, its mining in the Czech Republic, the impact of mining on the environment and ecological territorial limits.. The second part deals with the Thermo-dynamic working cycles in the power plant. Also deals with various technological parts of brown-coal power plant, including equipment and procedures for the cleaning of exhaust gases. The last part describes the most important individual brown-coal power plants in the Czech Republic, their brief history, the technical parameters and the planned service life.

Cogeneration
Martinek, Jan ; Šnajdárek, Ladislav (referee) ; Fortelný, Zdeněk (advisor)
This bachelor thesis is intended to handle the issue of cogeneration. There is presented the principle of cogeneration and its benefits. Cogeneration is compared to the separate production of power and heat. This work deals with the storage of electric energy and heat and also deals with used batteries. The next chapter discusses the impact of cogeneration to environment and at the end there are mentioned the main Brno’s cogeneration units and central heat distribution in Brno.
