Heating of Family House by Heat Pumps
Sláma, David ; Moskalík, Jiří (referee) ; Lisý, Martin (advisor)
This bachelor thesis deals with heating of family house by heating pumps. The main task was to design a suitable heating pump for a chosen family house. Here is given the method of calculation total heat loss of building. Depending on the performance characteristics are compared two types of heat pumps, and will be selected the appropriate one. The last part compares the seasonal performance factors (spf) 3 and 5.

Optimalize Application of Cascade Convection of a Heat Pumps
Hrnčíř, Zdeněk ; Šenk, Josef (referee) ; Gregor, Jan (advisor)
The introductory part of this diploma work contains a basic thought for the application of the heat pumps cascade connection and further I describe its function and define the notion of an optimum middle temperature.Then the direct comparison of two heats pumps cascade connection with an one-stage heat pump is shown there in a concrete example. The main part of the work is aimed to the determination of the most suitable variant for the heating and for the preparation of a hot service water in a benchmark family house. The systems of heatings are provided in options of a low-temperature floor heating and hot-water radiators. Both types of the heat pumps supply the warm to every heating system. It results into four possibles alternatives of the building heating.Besides of the alternatives mentioned above, a new variant of optimalised cascade connection was arisen during this work elaboration . The first stage of this connection which supplies the warm to the floor heating is disconnected out of the heating season and the second stage provides only a hot service water warming. The results of this work showed us that just this variant of a cascade connection causes savings in energy in comparison with an one-stage heat pump. In the conclusion of this work there are discussed the reached results and indicated the possibilities of a practical exploitation.

Air to water heat pumps
Špatenka, Jindřich ; Weismanová, Júlia (referee) ; Hejčík, Jiří (advisor)
Topic of the bachelor thesis are heat pumps air - water. The first part deals with the principle of heat pump and development since the inception to the present day, as well as a brief indication of other types of heat pumps and their adventages and disadvantages. In the next part are selected heat pumps from different manufacturers achieved by heating factors, performance and other parameters. Followed by used circuits of heat pumps. In the third section are described the component parts of heat pumps and their distribution.

Heat pump with accumalation
Kohout, Jiří ; Lisý, Martin (referee) ; Pospíšil, Jiří (advisor)
This diploma thesis deals with the assessment of SCOP of the heat pump installed in the selected building and with the determination of optimal size of accumulation which should help to heat pump work with higher temperature and higher SCOP. Annual savings of operating cost and return of investment from installation of accumulation tank are evaluated in this thesis. In the research part of this thesis are described the main components of heat pump, sources of low-potential heat and types of heat pump.

Bivalent heating systém with an air-water heat pump
Tvrdý, Miloslav ; Fiedler, Jan (referee) ; Pospíšil, Jiří (advisor)
The work is about bivalent heating system with an air-water heat pump. In the first theoretical part there is described princip, basic partition and possibilities of performance of the heat pumps. There are presented possible secondary sources for bivalent performance, too. In the second part there is processed actual offer of bivalent heating system with an air-water heat pump and there is choosed the optimal solution for heating real family house. There are also presented and confronted possible secondary sources for this solution and there is the confrontation with the others possible heating systems. There is complete economical evaluation in conclusion the work.

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.

Waste heat recovery from processes using heat pumps
Marada, Petr ; Zejda, Vojtěch (referee) ; Havlásek, Martin (advisor)
The aim of the bachelor thesis is to describe the possibilities of using waste heat from the processes by heat pumps. The first part defines the waste heat and deals with the possibilities and ways of its use. The next section describes the different types of heat pumps, their components and sources from which it is possible to draw the heat. The last part shows the calculation of return on investment to make heat pump for heating office buildings.

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.
