Comparison of photovoltaic and photothermal systems for hot water heating in an apartment building
Švéda, Richard ; Lachman, Jakub (referee) ; Toman, Filip (advisor)
This bachelor's thesis examines the comparative merits of photovoltaic and photothermal systems for domestic hot water heating. The introductory section provides an overview of solar radiation, its origin, and its striking the Earth´s surface. Thereafter, both systems are subject to detailed analysis and calculations. These systems are designed for a specific residential unit and evaluated from technical, financial, and operational perspectives. Based on these calculations and analyses, the most suitable choice for the given location is recommended.

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.

Heating of hot water by systme base on photovoltaic panels
Zdvořilý, Vítek ; Hejčík, Jiří (referee) ; Fišer, Jan (advisor)
The aim of the Bachelor thesis is to compare specific types of regulation for the effective heating water with using photovoltaic panels for the standard household. The follow types of regulation was taken into account: the MPPT controller, switching of load, switching of pannels connection and PWM regulator. The second part of the thesis is focused on design of photovoltaic system for domestic hot water heating which is designed for climatic conditions in Polička near Svitavy.

Heat pump for a family house
Lang, Martin ; Linda, Jakub (referee) ; Pospíšil, Jiří (advisor)
This bachelor thesis describes the function and types of heat pumps. It also deals with low-potential heat sources, their advantages, and specifics. Based on this information, a specific heat pump is selected. Subsequently, a technical-economic evaluation is carried out with heating by a solid fuel boiler and a gas boiler.
