Heat pump for resident heating
Abrahám, Jan ; Kudela, Libor (referee) ; Pospíšil, Jiří (advisor)
The bachelor thesis deals with the use of a heat pump for heating a family house. In the theoretical part of the thesis the principle of operation of the heat pump is introduced. This part also explains the coefficient of performance and describes the different types of heat pumps according to the heat source with their advantages and disadvantages. In the practical part the thermal losses of the selected building are calculated. The heating system is designed and finally the economical evaluation and the return of investment are determined.

Steam Turbine for Biomass Power Plant
Abrahám, Jan ; Fiedler, Jan (referee) ; Kracík, Petr (advisor)
Diploma thesis deals with the design of a condensing steam turbine with one controlled steam extraction. Its working range is 0 to 10 t/h. The first part contains the design of the heat balance scheme. The turbine has two unregulated steam extractions for low-pressure feedwater heater and outlet steam is cooled by water condenser. The main part is the design of the turbine flow channel with one regulative stage using impulse blading and 26 regular stages using reaction blading. The turbine rotating speed is 8500 rpm, which is strength suitable even in critical points. The following chapters are describing the design of the compensation piston and bearings. The consumption characteristic of the steam turbine is shown in the last chapter. Drawing of the turbine section is attached to this thesis. Final turbine power is 9259,7 kW and thermodynamic efficiency 85,5 %.
