The effective coverage of the heat demand using solar system
Vítek, Lukáš ; Horká, Lucie (referee) ; Vyhlídalová, Karolína (advisor)
This master thesis aims to design the heating system and HDW preparation in an apartment building. The first variant deals with condensation gas boiler as the only energy source, while the second variant combines the gas boilers with the solar thermal system. The apartment building is located in Prag and has three above-ground floors and a basement. In the basement is the technical room. Convectors are being used for heat distribution. The theoretical part deals with the introduction to the solar thermal system.

Systems of technical equipment in almost zero energy House
Bukovjanová, Eva ; Adam, Pavel (referee) ; Počinková, Marcela (advisor)
The aim of this thesis is the design and building services systems in buildings with energy close to zero. The thesis 2 variants were designed heating and DHW. In variant 2 is considered with the photovoltaic system to generate electricity that is used up mainly in the building. It is part of the thesis experiment, whose aim was to monitor and evaluate the structure of electricity consumption in the residential unit.

Heating with a heat pump
Mikoláš, Petr ; Počinková, Marcela (referee) ; Horák, Petr (advisor)
The bachelor's thesis is divided into three parts. The first part is theoretical and deals with history, principle of function and distribution of heat pumps and general description of solar systems and collectors. The second part is computational, which deals with the design of heating in an apartment house. It solves the design of the low temperature heating system with the air-water heat pump cascade and the design of the solar system for hot water. The last part is the project, which contains the elaborated technical report and the project documentation.

Design of an apartment building heating system
Kaša, Filip ; Maurerová, Lenka (referee) ; Vyhlídalová, Karolína (advisor)
The master's thesis aims to design heating and hot water supply in two variants for a new residential building in Nové Město na Moravě. The building consists of one underground floor and four above-ground floors. The heating system is designed for the above-ground floors, where residential spaces are located. Heating is not considered in the underground floor. Heat distribution to the spaces is ensured by panel radiators and pipe heating elements. The system is designed with copper piping as a hot water two-pipe system with a thermal gradient of 50/40 °C. The heating system is powered by a gas condensing boiler. Hot water supply is addressed in two variants. The first variant considers heating hot water using a gas condensing boiler. The second variant involves primary hot water heating through thermal collectors located on the sloped roof of the building, with additional heating provided by a gas condensing boiler. a simulation is conducted for the variant with thermal collectors, comparing primarily tubular and partially flat collectors from various manufacturers listed in Zelená úsporám 2023 catalog.

Energy Evaluation of Technical Services Systems
Cap, Petr ; Horák, Petr (referee) ; Vendlová, Lucie (advisor)
This Master’s thesis deals with the energy evaluation of existing buildings sports-recreational company complex in Brušperk. For this purpose provides a comparison of selected fuels as an energy source for the heating in terms of economy and their impact on the environment. In addition, provides an overview of existing legislation for elaboration of an energy audit. To complement shows the calculation of return on investment in solar panels on the roof of one of the objects. Calculation is based on the results of performed experimental measurement. Finally, the thesis presents a comparison of energy performance of buildings simulated in the Bsim software with reality.

Solar hot water storage tank
Vyhlídalová, Karolína ; Vranayová,, Zuzana (referee) ; Hirš, Jiří (referee) ; Horák, Petr (advisor)
The solar hot water storage tank is off great importance in the solar collector array. It allows transformed energy accumulation thus deals with the inconsistency between supply and demand. The suitable design of the storage tank can improve system efficiency. The storage capacity represents the balance between the amount of stored hot water and the tank's heat losses. The design of the storage capacity is based on three hypotheses. The coverage of hot water demand by solar energy, the ratio between storage capacity and solar thermal collector area and the prediction that the storage capacity corresponds to one- to twofold hot water demand. The purpose of this thesis is to share an understanding of the solar storage tanks design and to improve the design through numerical simulation, experimentations and general calculations. It also focuses on the confirmation of the used hypotheses and determination of the best way to design the solar storage tank for general practice and further potential discussions. The simulation model has three variables – the storage capacity, collector area and the number of occupants. The intent is to find the interdependence of these three variables. The purpose of the simulations is to modify the design of the solar tank based on the mutual influence of studied parameters. The modifications are performed based on the users' needs.
