The issue of energy-efficient home heating
Kollár, Ľubomír ; Hrnčířová, Michaela (referee) ; Baláš, Marek (advisor)
Low-energy houses are becoming more common and requested. The Bachelor's thesis focuses on heating and ventilation of low-energy houses. The beginning chapters describe and explain basic principles of these buildings and basics of air-handling and heating systems. The main part of the work overviews contemporary heating and ventilation systems while pointing out their advantages and disadvantages. The work includes a design of heating and ventilation of low-energy house.

Evaluating and modeling of fouling process in heat exchanger
Čirka, Martin ; Kilkovský, Bohuslav (referee) ; Jegla, Zdeněk (advisor)
This diploma thesis discusses fouling processes and mechanisms of industrial heat exchangers, with focus on shell side fouling of heat transfer area by flue gases, and eventually taking fouling into account, or more precisely its modeling and predicting by calculation. Thermal-hydraulic design of heat exchanger is focused mainly on shell side, as flue gases are dominant process medium in terms of fouling and heat transfer. Based on available operational data of evaluated industrial heat exchanger, specific process has been developed to determine by calculation, or more precisely predict change of fouling factor throughout operational period of heat exchanger. Usage and various options of this specific calculation technique are being discussed in conclusion, whether there is a potential to use this technique regarding more complex operational inputs or prediction of fouling process for different operational regime of heat exchanger.

Aspects of an experimental solution with the use of geothermal energy in Balneotherapy
Miček, Denis ; Horák, Petr (referee) ; Kabele, Karel (referee) ; Hirš, Jiří (advisor)
The Earth, our home planet is world unlike any other. The third planet from the sun is the only place in the known universe confirmed to host life. We, the humans always headed up to reach set up goals, innovate our technologies and way of living. The fact that, we had never been aware of is that this race to our bright and modern future is destroying our home. By this time, the global temperature arises by 1,9 oC since 1880, 427 gigatons of ice sheets were melted and there are 414 ppm of carbon dioxide particles in our atmosphere. As the trend is changing and we are above to think in green way of living, there is necessity to set up roadmaps and actions plans to stop, eventually decrease the damage which was already caused. The European union started to measure and provide actions plans to decrease the pollution and production of greenhouse gases since the year 1990 – which was set up as reference year for comparison to progress. This arrangement forced the countries to start evaluating the current statuses of their public and industrial sectors in terms of climate changes and provide climate plans for reducing the greenhouse gases. The most important part of climate action plans is to involve the renewable sources of energy into all public and industrial sectors and in this way start the green way of living. Therefore, the investigation and proper understanding of this problems must be the main focus of technical universities and scientific sectors. This dissertation thesis is the summit of 8 years studies and investigation in field of renewable sources of energy, mainly focused on geothermal energy which production in year 2002 was 0 GWh. The main goal is to experimentally analyze designed solutions, elaborated within master and bachelor thesis in real operation of Balneotherapy departments at Slovak Health Spa Piestany, Slovakia from energy, economic and environmental point of view, to set up energy, aqua management and fully understand the way of involvin
