Design of domestic energy supply system using renewable energy sources
Gaborčík, Michal ; Pavelka, Tomáš (referee) ; Matoušek, Antonín (advisor)
This bachelor thesis deals with possibilities of utilization of renewable energy sources for domestic power supply. In theoretical part is created research about available technologies using solar collectors, photovoltaic systems and heat pumps. In practical part there are calculated expected values of energy needed for heating of family house, domestic hot water heating and electrical consumption of appliances. These values are bases for system design using air to water heat pump for heating and domestic hot water heating. As far as photovoltaic system is concerned there is comparative design of systems using polycrystalline and thin-layer technology. At the end both designed systems are evaluated from technical and economical points of view.

Heat pump for a family house
Chlud, Jaroslav ; Köbölová, Klaudia (referee) ; Pospíšil, Jiří (advisor)
The topic of the final bachelor thesis is heat pump heating. The aim of the thesis is to design a system using heat pump technology in a family house and economic and energy assessment of the designed system. This thesis focuses on research about heat pumps and usable low-potential heat sources. The envelope method is used to estimate the heat loss. The calculation of heat loss and heat demand is facilitated by using a calculation tool from a web source. The design of the storage water heater is calculated using the standard. Operat-ing costs and payback are calculated by simple formulas. As a result of the work, the design of heat pump, drawing heat from the ground, and the connection of the device to the existing system is implemented, which corresponds to the assignment of the work. A reduction in the total heat demand and therefore energy consumption due to energy saving measures is achieved. The system can benefit by saving operational costs for heating and hot water. The short payback period shows that the investment in the selected heat pump is worthwhile. This work can serve as a basis for the real implementation of the heat pump design.

Retrofit of heating system in a family house
Doležel, Pavel ; Hejčík, Jiří (referee) ; Charvát, Pavel (advisor)
The master’s thesis deals with the solid-fuel fired furnaces, complying with the new emission legislation, and their application in central heating. The introductory part of the thesis focuses on the theory of solid fuels combustion, pertinent legislation, and various designs of solid-fuel fired furnaces. The main part of the thesis deals with the design of a central heating system for a townhouse with a solid-fuel fired furnace as the primary heat source for central heating. A roof-mounted PV system was considered for solar-assisted domestic hot water heating. The energy performance of the house was evaluated with the use of the degree-day method and also with a detailed computer simulation in TRNSYS. As an appendix, the thesis includes the detailed engineering calculations and the engineering drawings and diagrams of the central heating system.
