Dynamic model of a heat pump with plate heat exchangers and ecological refrigerant
Strmiska, Pavel ; Řehák Kopečková, Barbora (referee) ; Pokorný, Jan (advisor)
For the optimization of a heat pump, there is a need to possess its dynamic model. One of the freely available tools for creating such a model is the language Modelica and its open-source compiler OpenModelica. The thesis aims to research options for creating dynamic models of refrigeration circuits with the ecological refrigerant R290 and its components in Modelica, to create the circuit and subsequently validate it using previously measured data. Models of basic components of heat pumps - compressor, condenser, evaporator and expansion valve are created in a way described in the thesis. A simplified model of a refrigerant loop is also created

With wall heating systems
Bendová, Martina ; Topič, Jan (referee) ; Počinková, Marcela (advisor)
This work deals with the topic "Systems with wall heating". On this theme is elaborated theoretical part. Further experimental part, which deals with the measurement of wall heating and comparing the results with the software CalA. Subsequently, this topic is applied to the specified building in which the wall heating, among other things dealt with. The project addresses the design of central heating, water heating, water heater design power units and air tempering lawn for future newly built free-standing facilities football club. The project is designed in two versions. In the first variant of the heat source heat pumps air-water. In the second variant is the heat source hot water pipe which is connected to transfer water-water station with plate heat exchangers.

Heating of the sports center
Fuksa, Lukáš ; Horká, Lucie (referee) ; Počinková, Marcela (advisor)
Subject of this bachelor thesis is the design of heating in sport centre. Thesis includes three parts. The first theoretical part solves available ways of heating of large spaces and hall objects. The second calculations part solves design of heating in sport centre. This part includes heat loss, design heating surfaces, hot water production, dimensioning, safety equipment and other calculations. The third part solves drawings with technical report.

Heating of a multifunctional house
Mrlina, Pavel ; Vendlová, Lucie (referee) ; Počinková, Marcela (advisor)
The main content of the bachelor's thesis is the solution of heating for a multifunctional building. The thesis is divided into three parts: theoretical, computational, and design parts. The theoretical part focuses on heat substations. The computational part is dedicated to the design of heating and hot water preparation for the multifunctional building. The building houses a dental hygiene office, administrative spaces, a shop, staff lounges, and storage areas. The building is heated using panel radiators and bench convectors. The heat source is provided by a heat substation connected to a central hot water supply system. The heat substation is thermally independent and is equipped with plate heat exchangers for both the heating system and hot water heating. The design part includes drawings and a technical report. These documents are prepared based on the computational part.
