Efficiency assessment of heat pump
Dvořák, Martin ; Milčák, Pavel (referee) ; Gregorovičová, Eva (advisor)
The brachelor’s thesis focuses on assessing the effectiveness of a heat pump for heating a family house. The theoretical part of the thesis comprehensively discusses the issue of heat pumps, including their ecological contribution. Based on the completed research, a heat pump is chosen in the practical part. Then the energy demand of the building is calculated, on the basis of which the energy evaluation of the proposed system is carried out in individual months. At the end of thesis, a technical-economic comparison with heating with an electric boiler is presented.

Heating and cooling of the administrative building with hall
Hečko, Jakub ; Horká, Lucie (referee) ; Topič, Jan (advisor)
The bachelor thesis deals with the design of heating and cooling for an administrative building with a storage hall. The theoretical part focuses on large-area radiant heating. The computational part includes a detailed design of heating for the administrative building with a storage hall and a design for cooling the administrative building. The administrative building is heated by underfloor heating, while the storage hall is heated using hot water radiant panels. Cooling for the administrative building is designed using two-pipe cassette fan coil units. The source of heat and cold is an inverter air-to-water heat pump. Ventilation is considered forced, using air handling units. The design of hot water preparation is addressed as a priority. The project part includes drawing documentation and a technical report.

Grate Biomass Boiler
Kleinová, Martina ; Křemínský, Pavel (referee) ; Lisý, Martin (advisor)
The main content of the thesis is the design of a steam boiler for biomass of smaller outputs of 6 MW. The fuel of the boiler was chosen spruce wood chip by 40% humidity. The parameters of the superheated steam are a temperature of 420 °C and a pressure of 40 bar. The work includes stoichiometric and thermal calculations, which are determined by fuel composition and output steam parameters. In the annex to the thesis, individual heat-exchange surfaces and the dimensional design of the boiler, including the layout, are marked. This work also features calculations of pressure losses on the part of both media.

Evaluation of real heat pump installation operation
Pliml, Patrik ; Gregorovičová, Eva (referee) ; Pospíšil, Jiří (advisor)
The bachelor thesis on heat pumps focuses on various aspects related to heat pumps, including heat transfer or economic benefits. The function of the heat pump is described in a review way. Furthermore, the main heat pump components, low temperature energy sources and different types of heat pumps are presented. The main part of the thesis is focused on the evaluation of the heating of a family house after a real installation of an older heat pump. To solve this part, own measurements were used as well as a calculator to calculate the heat loss of the heated building. These results formed the basis for the evaluation of the system in terms of operational, technical, and economic aspects. A table was created in which the data on the electricity con-sumption for the heating period was kept in order to compare the heat losses obtained from this calculator. The aim of the last part of the bachelor's thesis was to design the heat pump in order to reduce the electricity requirements for heating. This requirement is based on the results obtained in the previous part and corresponds to the current standards of new heat pump technologies. The output of the thesis is a new heat pump design in order to reduce the electricity consumption.

Study of return of heat sources for a family house
Pavlík, Michal ; Lisá, Hana (referee) ; Toman, Filip (advisor)
This bachelor’s thesis focuses on the calculation and selection of the most suitable heat energy source for a selected family house. A brief overview of these heat energy sources serves for a general understanding and clarifies their basic functions. By calculating the heat loss through walls, heated and unheated rooms, functional parts of the building, the ground, and ventilation, the total energy required for heating the house for one year was determined. Additionally, the total energy needed to heat water for 4 people every day throughout the year was also identified. Based on these collected values, four energy sources were selected and subsequently compared with each other in uncluttered graphs. The most suitable heat source was chosen after an economic analysis of return on investment.
