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.

Energy efficiency of heat pumps
Bártů, Marek ; Hejčík, Jiří (referee) ; Pospíšil, Jiří (advisor)
This diploma thesis deals with the energy efficiency of heat pumps, especially efficiency of air/water system. In the this thesis is simply described the principle of the heat pump and function of each component. It shows the issues of determining the parameters of performance of the heat pump and also describes verification in according to applicable standards. The diploma thesis gives an analysis of determining the energetical efficiency and calculation of coefficient of performance, in other words, the seasonal heating coefficient of performance. Seasonal energy efficiency of selected samples of heat pumps for the heating season is designated for specific climatic conditions.

Alternative Energy Resources for Family House
Němec, David ; Brázdil, Marian (referee) ; Špiláček, Michal (advisor)
This bachelor thesis is focused at an issue of thermal energy supply for family houses from renewable resources. The aim of this thesis is to provide a summary of possible thermal energy supplies from renewable resources (solar collectors, heat pumps). After that follows a draft and economic evaluation of these systems for individual sources of thermal energy. In introductory section a solar energy is described. It is a significant part of renewable energy. This part is followed by review with description, composition and principle of individual types of solar collectors and heat pumps. Next part is focused on draft of these systems. Conclusion is then dedicated to energy evaluation of individual designed systems.

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.

Heating Asylum House
Gongolová, Klára ; Topič, Jan (referee) ; Počinková, Marcela (advisor)
In my thesis, i prepare proposals for heating and hot water in a shelter in the Havirov city. It is a renovated brick building that has two floors. The property also adjacent kitchen with workshop. In the calculation deals with the proposal of heating surfaces, plumbing, heating water and heat. I object to proposed plate radiators and pipe. Distribution of hot-water, two-pipe, symmetrical. I opted for the joint preparation of heating water for the production of domestic hot water heating and water heating. The heat source is a cascade of two heat pumps. In the theoretical part I focus on heat pumps.

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.

Assessment of cooling and heating factor of real heat pump
Tupcová, Tereza ; Andrys, Petr (referee) ; Rubina, Aleš (advisor)
The diploma thesis deals with the issue of replacement of non-ecological refrigerant R22 according to the requirements of relevant juristic regulations and of subsequent influence of this replacement to the efficiency of air conditioning systems. The theoretical part is focused on proceeding processes in thermodynamic cycles and during heat transfer, then determines calculation of cooling and heating factor in context with experimental measurement. The experimental measurement utilizes to the assessment of operation of heat pump after refrigerant replacement and it is source for the composion of economical evaluation of alternative solutions due to the particular choice of refrigerant replacement.

Heat pump in cooperation with PV for family house
Drašar, Vojtěch ; Vrána, Michal (referee) ; Mastný, Petr (advisor)
The bachelor thesis deals with the design of a heat pump in cooperation with a photovoltaic system for a family house. The theoretical part describes the principles of the heat pump and the photovoltaic system. The thesis presents the methods of operation of the heat pump, the principles of building cooling, the connection of the PV system to the grid, or the methods of storing excess energy. In the practical part, the consumption of a typical family house has been determined by means of typical supply diagrams. The consumption is based on hourly statistical values for the year 2021. From the obtained values a pump was designed. Another objective of the work was the placement of photovoltaic panels on the roof. The power plant is considered as a hybrid, in order to maximize the consumption of the energy produced and the use of energy at the point of generation. For this, a battery system was also designed. The work includes an energy and economic evaluation, including the payback of the combination. For the economic evaluation, a subsidy from the New Green Savings 2021+ program was considered. The proposed solution has applications in both renovation and new construction, where the emphasis is on minimizing air pollutants and also the use of ecological resources.
