The development of the model of PV system for electric water heating
Sochor, Tomáš ; Radil, Lukáš (referee) ; Ptáček, Michal (advisor)
This thesis deals with designing of a model of a photovoltaic system for domestic water heating in program PSCAD. In theoretical part, an analysis of photovoltaic systems regarding their connection to electrical grid is made. Then a description of chosen concepts of photovoltaic systems for domestic water heating is made. Furthemore, a photovoltaic cell is described with regard to its mathematical description and influence of different parameters on its volt-ampere characteristics. Also, a common topologies of DC-DC converters are described. Control is also related to these converters, that is why a fundamental MPPT algorithms are described. Practical part deals with designing of chosen concepts of photovoltaic systems for domestic water heating in program PSCAD. A basic simulations with regard to behavior of these systems are performed, especially a relationship with respect to irradiance and temperature. Simulations are then discussed in the conclusion.

Building services of near zero energy buildings
Šťastný, Radek ; Tůmová, Eliška (referee) ; Hirš, Jiří (advisor)
Master´s thesis is focusing on zero energy building with technical equipment. The building was built in 70. decade of last century. It has been using for sport and cultular events until these days. Restaurant was connected to sport hall. First part is focusing on zero energy building and technical equipment, their using, combination and optimal connecting in systém. Second part solving how many fotovoltaic panels must be in the system to reching economic advantage. In third part is solving how to connecting fotovoltaic panels to the system.

Heating and hot water preparation of recreation center
Hakl, Jaroslav ; Horká, Lucie (referee) ; Počinková, Marcela (advisor)
Content of this bachelor thesis is heating and hot water preparation of recreation centre in the village Ostužná, district Jeseník. Object have 2 above-ground floors. Ground floor is mainly used to meet people in play room or in common room. First floor is situated six accommodation units with private bathroom and toilet. Technical facilities are situated in ground floor and is consists of boiler room and the adjacent fuel storage. For heating is primary used grasifying boiler. Secondary source for hot water preparation is solar systém, that is supplemented by an electric heater in the absence of sunshine. Heating systém is in horizontal double-pipe version with distributor and collector in each floor. The Individual branches on the distributor and collector connected are sections of a single accommodation unit, that can be individually regulated. Radiators are designed as boards in the VK design.

Design of a heating system for an office building
Vítek, Lukáš ; Horká, Lucie (referee) ; Vyhlídalová, Karolína (advisor)
The aim of this bachelor thesis is to design a proposal of space heating and water heating system for an administrative building in Ostrava. The building has four above-ground floors and an underground floor. In the underground floor are located technical building background, stocks and a parking. In the above-ground floors are administrative offices. The heating is solved as a water heating, with a distribution of the heat into the space using panel radiators and convectors. Water heating is solved by an accumulation heater. As a heating energy source serves a cascade gas boilers. We can find in the whole building a forced ventilation. The theoretical part of this thesis deals with the BIM technology.

Measuring and regulation of computer controlled solar systems: Vizualization of energetic systems
Vlčnovská Kotlíková, Silvie ; Mašek, Ivan (referee) ; Půčková, Helena (advisor)
This work is oriented on study and evaluation of performance of real operating solar system. There was made analysis of actual technological unit and there was suggested mode of measuring of nodal parameters. There was made interconnection between the head operating unit of the solar system and the web server. And there was prepared software for grafical image of time and temperature dependence and for data transfer to ready web application. It primarily talks about increase of efficiency of real technological unit through regulating of parameter that is using up of accumulated energy.
