Earth heat sources for heat pumps – flat collectors
Houdek, Milan ; Štětina, Josef (referee) ; Jaroš, Michal (advisor)
The aim of this bachelor’s thesis is to summarize the types of flat collectors and to compare them with the other sources of heat for heat pumps from the investment standpoint. Then to compare this kind of heating with the other kinds of heat sources for households in light of investment and operation costs. Finally, to find out usability of this heating source based on above-mentioned criterions.

Using a heat pump
Tretera, Robin ; Křivík, Petr (referee) ; Jandová, Kristýna (advisor)
This diploma thesis provides basic information about the thermal pumps and photovoltaic systems. The heat pumps are described regarding their construction and sources of low potential heat. The description of photovoltaic systems explains the main principle of transformation the solar light to electric power and possible cooperation of this systems with the heat pumps. In practical part of the thesis there is a description of the assessed building and calculation of its thermal losses. It is followed by three designs of the thermal pump systems which are supposed to replace the original way of heating - the electric boiler. One of the designs is supported by photovoltaic system. The final part of the thesis provides the calculation of required heat sources for house and water heating, the operation expanses of all three heat pump designs, prices of electric energy and economical reliability of described solutions.

Domestic heat pumps
Merta, Libor ; Lisý, Martin (referee) ; Pospíšil, Jiří (advisor)
The Bachelor´s Thesis deals with domestic heat pumps. It is devided into two basic parts. In the first part, an operating principle, components and various types are described. Particular kinds of low-energy sources including characteristical features and comparision are mentioned there as well. In the second part, a project for a domestic heat pump is prepared. The project includes proposition of a particular heat pump, a borehole and an amount of heat needed for heating and a preparation of warm water. At the end, a complete economical balance including an economic return of the investment is mentioned.

Heat pump heating for a house
Loibl, Jan ; Hrnčířová, Michaela (referee) ; Nerud, Pavel (advisor)
The theoretical part of the bachelor thesis deals with introducing to the issue of heat pump systems. The functioning principle of the most widely used heat pump type is explained here as well as its coeficient of performance, its operational modes and fundamental components. In addition, possible ways of heat pump systems application in terms of obtaining lowpotential heat are introduced. In the practical part the calculation of thermal loss of selected family house is discussed together with the calculation of heat requirements for heating and domestic hot water. The following part focuses on the selection of the most appropriate type of heat pump systems for covering heat demands of the selected house. The final part poses economical assesment of the designed heat pump system including the calculation of investment recovery.

Pile Foundations - Energy Piles
Hoza, Martin ; Leiter, Augustin (referee) ; Glisníková, Věra (advisor)
At a time when ecology and renewable energy sources come to the fore, the use of geothermal energy appears to be one of the suitable alternatives. The aim of this paper is to explain the function of ground source heat pumps, to mention factors affecting the efficiency of the system and discuss the technology of energy piles realization. This paper also focuses at risks associated with the soil temperature influencing and shows examples of realization.

Simultaneous utilizing of a heat pump and solar panels in a heating syste
Gongol, Jakub ; Chroboczek, Libor (referee) ; Pospíšil, Jiří (advisor)
My bachelor thesis focuses on simultaneous utilizing of a heat pump and a solar thermal collectors. I introduce principle and types of heat pumps and thermal collectors. I also introduce different sources of low-potential heat, which can be used for a heat pump. In conclusion, heat pump and solar collectors are chosen for a type house. I calculate costs needed for heating house without and with heat pump. These costs are compared and economic return is evaluated.

Potencial for geothermal energy utilizing
Kohut, Vojtěch ; Bogdálek, Jan (referee) ; Pospíšil, Jiří (advisor)
The main purpose of this bachelor’s thesis is to collect all available literature, from which can reader obtain basic knowledge of geothermal energy practical usage possibilities. Geothermal energy comes from heart of our planet. As such it is ranked among renewable energy sources. Thesis describes direct heat utilisation for heat supply systems and electric power generation in geothermal power plants. It is also entertain about possible usage of low-potencial geothermal energy by the help of heat pumps.

Heating of Family House by Heating Pumps
Kordiovský, Jan ; Moskalík, Jiří (referee) ; Lisý, Martin (advisor)
Bachelor’s thesis deals with the topic of heating of family house by heating pumps. Fundamental principle of their function is there explained as well as possibility of performance evaluation, different modes of operation with an additional heat source and basic distribution according to divergent criteria. In the next part were selected three types of heating pumps: air/water, ground/water and water/water. Advantages and disadvantages are evaluated for each of them. There is the question of the appropriateness of application to family houses.
