Design of a solar system for hot water heating in a family house
Reiskup, Matěj ; Tuhovčák, Ján (referee) ; Jaroš, Michal (advisor)
The thesis discusses the use of solar-powered water heating system in a family home. The introductory chapters present traditional methods of heating water and solar energy concepts. Following chapters compare the advantages and disadvantages of solar-powered water heating with more traditional heating methods and the core parts of such system. Finally a solar-powered heating system for a family home is proposed, including cost calculation, return on investment and comparison with a common heating system.

Effect of geographical location on solar systems performance
Kuljovský, Martin ; Weismanová, Júlia (referee) ; Jaroš, Michal (advisor)
The sharp price increase and the impending depletion of fossil fuels has led to an increasing interest in renewable resources. This thesis deals with one of the most lucrative substitution between renewable sources - the solar energy. The introduction describes the emergence and spread of energy in the universe, then is devoted to basic distribution of collectors and informs about the possibilities of their use. In particular, it contains formulas for calculating the basic performance characteristics and then comparing differences between panels. Finally, it compares the effectiveness of collectors for different geographical locations in the Czech Republic.

Measurement and control system of an air-ground heat exchanger
Bielik, Jan ; Štětina, Josef (referee) ; Jaroš, Michal (advisor)
Diploma thesis deals with design of measurement and control system of an air-ground heat exchanger, which is placed in area of FME BUT in Brno. System is built in development environment LabVIEW and it is using modules CompactDAQ from National Instrument. Developed system managed trial operation, during which was designed additional changes of measurement equipment for determine another magnitudes, which help us with future evaluation of benefit of air-ground heating exchanger. It was designed some operational modes, which solve different ways of control air-ground heat exchanger.
