Retrofit IP-LP Section Steam Turbine 300MW
Pavlik, Richard ; Fichtl, Richard (referee) ; Fichtl, Richard (referee) ; Fiedler, Jan (advisor)
The aim of this master’s thesis is a retrofit of condensing three case steam turbine K300-170 with reheating. In the first part, the heat balance of the system is calculated for given parameters. The design of the flow section is focused on the combined intermediate pressure and low pressure turbine section and it consists of defining rotor and blading characteristics. In the stress control, the stress of the designed blading is checked and for the conclusion the shaft seal losses and their effect on the overall output power of the turbine are estimated. The drawing of axial section of combined intermediate pressure and low pressure turbine section is also included in the thesis.

Family Houses Heating by Heat Pump
Zeťák, Marek ; Kalivodová, Markéta (referee) ; Lisý, Martin (advisor)
Heat sources are a daily part of our lives. The increasing demands for efficient, low-cost and eco-friendly heating of a family home can be satisfied with a heat pump. The main benefits include eco-friendly, efficient and unattended operations with low operating cost. This bachelor thesis provides information on how the heat pump works, what types exist and explains the concepts associated with them. Due to the decreasing power at low temperature, heat pumps are often installed in a bivalent connection with an additional heat source. The heat pump, like any other device, undergoes constant upgrades to improve the parameters and its function. In the final part of the thesis, a basic economic study of a new heat source for a model house is carried out, where the heat pump is one of the proposed options.

Impact analysis of renovation on the normal price of a single-family house in Kyjov
Kouřilová, Vendula ; Hlavinková, Vítězslava (referee) ; Komosná, Milada (advisor)
The subject of this master thesis is detection how the redevelopment and refurbishment affect regular price of family house. For valuation I chose the building in which I grew up so I know it very good. The family house is located in small south-moravian town Kyjov, in district Nětčice. The family house has a basement and two upper floors. Constructions were completed in 1962. Since 1976 many quite expensive redevelopment and refurbishment have been done. For property valuation is used method of direct comparison with the use of database of similar family houses in Kyjov and also cost method according to law number 441/2013 Sb. Valuation is done in two versions – for building in original condition (in 1985) and in current condition. All at once a couple of variants of redevelopment, which are common nowadays, and for one variant is made the itemized budget. Result of this master thesis should be detection if it is better to buy house after redevelopment and refurbishment or house in original condition and make these structural modifications until then.
