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.

Wall-Hung Heat Pump
Foltys, Jan ; Rapta, Patrik (referee) ; Hejčík, Jiří (advisor)
This thesis deals with the design and analysis of a wall-hung air/water heat pump that has the potential to replace existing wall-hung gas boilers in households. The thesis includes a detailed analysis of the principles of heat pump operation, an evaluation of existing technologies on the market, and the design of a new system. The thesis also extends to the optimization of the evaporator chamber, which is part of the design. It included CFD simulation, experimental verification, and design modifications were carried out. The results show that a properly designed heat pump can be an efficient alternative to traditional gas boilers, contributing to decarbonization and improved energy efficiency.

Heat pumps testing methodology
Španihelová, Kateřina ; Kamenský, Petr (referee) ; Hejčík, Jiří (advisor)
This thesis deals with the methodology of heat pumps testing. The first part covers the basic principles of a heat pump from the thermomechanical point of view, the description of the heat pump basic components and low-potential heat sources. The next section describes the parameters of heat pumps according to which we can evaluate their effectiveness. The last part is targeted on the issue of testing heat pumps including a description of the test methods and description of the test heat pump air-water.

Evaluation of heat pump operation data
Charvátová, Marie ; Fiedler, Jan (referee) ; Pospíšil, Jiří (advisor)
This diploma thesis deals with the issue of heat pumps as devices using low-potential heat of the surrounding environment for heating of buildings. In the theoretical part of the thesis there are described various types of these devices, the sources of low-potential heat and the possibilities of heat energy accumulation. The practical part of the thesis is focused on processing and evaluation of operational data of air/water heat pump used for heating of family house and assessment of importance of accumulation tank in heating system. Part of the thesis is also a proposal of optimization of heat pump control.

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.
