Monitoring of the performance of an air-to-water heat pump under real operating conditions
Elger, Jiří ; Jaroš, Michal (referee) ; Charvát, Pavel (advisor)
he Bachelor´s thesis on „Monitoring of the performance of an air-to-water heat pump under real operating conditions“ deals with the evaluation of a heat pump operation in a family house with a subsequent finding of the dependence of the heating factor and thermal performance on air temperature. The first part is dedicated to the theory of heat pumps, their categorization and explanation of the basic concepts. Next, we compare the performance characteristics and the coefficient of performance of heat pumps from different manufacturers. In the second part we describe measurements of a real heat pump which is used in a family house, the measuring instruments used, and particular measuring procedures. The third part shows the measured values plotted on charts, the measured values are analyzed, and the heat pump is checked for its suitability.

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.

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.

Domestic heat pumps
Housírek, Jiří ; Baláš, Marek (referee) ; Pospíšil, Jiří (advisor)
The Bachelor´s thesis “Pump Heats for Heating Residential Buidings“ is divided into three parts. The first part explains the principle of pump heads, characterizes individual parts, describes interconnected relations, analyses theoretical diagram of the Carnot Cycle and division of pump heads according to sources of getting heat. The second part deals with particular type of heat consumption – water – which should be suggested for chosen residential building. Then follows a brief description of a chosen object, principal parameters of the object and interconnected summary of calculating figures and particular calculation of energetic demand of the building. The third part deals with economic analysis of a chosen system of heating and its financial return (return on investment) when two systems of heating are compared. The first one uses only gas boiler and the second one heat pump. The conclusion gives a particular evaluation of advantage of a suggested solution.

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.

Heating the building pedagogical-psychological services
Vlasák, Vojtěch ; Adam, Pavel (referee) ; Počinková, Marcela (advisor)
My bachelor’s thesis deals with a heating system designed for a four-storey building in which a pedagogical-psychological centre is based. The heating installation uses an air/water heat pump and a low-temperature forced water circulation system. For all storeys, the design proposes panel heaters, the only exception being one tubular radiator. As for ventilation, it is designed as a forced balanced ventilation system. Last but not least, the thesis includes a hot-water preparation system which also uses the heat pump.

Termoakustika
Trávníček, Zdeněk
The thermoacoustic energy conversion systems can operate as heat pumps (or refrigerators which are based on the same principle) or prime movers. The design optimization of the thermoacoustic refrigerator was made using two methods, namely the optimization based on the cooling load maximization and on the coefficient of performance (COP) maximization. The highest COP can be achieved with the noble gas mixture helium-xenon (62%-38%) as the working fluid, while the highest cooling load can be achieved with pure helium.
