Heat sources for nearly zero-energy buildings
Zábovský, Ján ; Fojtlín, Miloš (referee) ; Hejčík, Jiří (advisor)
This bachelor's thesis deals with the topic of heat sources for nearly zero energy buildings. It is divided into three parts. The first part of the thesis describes the term „nearly zero energy buldings“ and its differences across European union and especially Czech and Slovak republic. The next part summarizes various types of systems and devices, which are directly or indirectly involved in maintaining interior thermal comfort. It also assesses their applicability to buildings with nearly zero energy consumption. The final part of the thesis consists of the design of several input parameters for the selected model house. A suitable heat source is suggested for each of the variants.

Heat pump for a family house
Chlud, Jaroslav ; Köbölová, Klaudia (referee) ; Pospíšil, Jiří (advisor)
The topic of the final bachelor thesis is heat pump heating. The aim of the thesis is to design a system using heat pump technology in a family house and economic and energy assessment of the designed system. This thesis focuses on research about heat pumps and usable low-potential heat sources. The envelope method is used to estimate the heat loss. The calculation of heat loss and heat demand is facilitated by using a calculation tool from a web source. The design of the storage water heater is calculated using the standard. Operat-ing costs and payback are calculated by simple formulas. As a result of the work, the design of heat pump, drawing heat from the ground, and the connection of the device to the existing system is implemented, which corresponds to the assignment of the work. A reduction in the total heat demand and therefore energy consumption due to energy saving measures is achieved. The system can benefit by saving operational costs for heating and hot water. The short payback period shows that the investment in the selected heat pump is worthwhile. This work can serve as a basis for the real implementation of the heat pump design.

Design of a weekend house heating
Rajdlík, Lukáš ; Pech, Ondřej (referee) ; Jaroš, Michal (advisor)
This master’s thesis deals with design of different variants of heating and warming of hot service water for holiday building (year-round weekend house, made of bricks). After calculations of the design heat load and heat requirement for heating and warming of hot service water for different types of operations the suitable heat sources are chosen. For heat sources the general design of heating is made. In the end the thesis includes economical analysis for each variant in view of investment and operating costs. The most suitable heat source is chosen from the results of analysis.

An assessment of returnability of solar collectors installation in low-energy family house
Hrbata, Jiří ; Pešek, Martin (referee) ; Jaroš, Michal (advisor)
Increasing of standard of living, automation and mechanization of production and industrial growth lead into energy need growth. At the same time the energy prices continuously rise and it is still more preferable to use renewable energy, particularly solar radiation. This thesis contains basic information about usefulness of solar radiation, solar collectors and ways of their integration into heating systems. Particularly, it deals with the assessment of returnability of solar collectors instalation in the low energy family house. It contains calculations of necessary heat for heating, hot water heating and energy gains from solar collectors. Returnability assessment is demonstrated on concrete example.

Design of heating of retirement home
Kouřilová, Klára ; Vyhlídalová, Karolína (referee) ; Horká, Lucie (advisor)
The main aim of this bachelor thesis is design of a heating system of the retirement home. The theoretical part deals with ensuring of thermal comfort and possibilities of building temperature regulation. The second part of this thesis, the calculation part, includes design of panel radiators, dimensioning of heating system, design of hot water preparation and design of heat source. As the heat source is chosen gas condensing boilers for heating system and hot water system. The third part contains documentation for construction of heating system.

Heating of administrative building
Bobek, Jan ; Počinková, Marcela (referee) ; Topič, Jan (advisor)
The dissertation deals with heating of the administrative building. The building is heated with the floor heating and the panel heating units. The heating source is an air to water heat pump with a bivalent heating from the central heat supplying (CZT). I deal in the project with design, dimension and connection of all these parts.

Heating of Family House-Heat Pumps
Choutka, Petr ; Čupr,, Karek (referee) ; Treuová, Lea (advisor)
The bachelor’s thesis contains a proposal of the heating of a detached house and a proposal of a suitable heating source. In the first part of the thesis there is an explanation of basic kinds of heating systems and types of heat pumps. The second part includes the description of the building, the determination of its basic parameters, the calculation of the heat loss and the heat demand for the whole household. Then a proposal of a heating system and a proposal of a suitable heating pump follow. In the end there is the comparison of the expected heating costs.

Heat pump for a family house
Lang, Martin ; Linda, Jakub (referee) ; Pospíšil, Jiří (advisor)
This bachelor thesis describes the function and types of heat pumps. It also deals with low-potential heat sources, their advantages, and specifics. Based on this information, a specific heat pump is selected. Subsequently, a technical-economic evaluation is carried out with heating by a solid fuel boiler and a gas boiler.
