Fine particles and air-cleaning
Knebl, Viktor ; Pospíšil, Jiří (referee) ; Poláčik, Ján (advisor)
The air, water or soil pollution is one of the major problem facing our society. Whether it is the production of large amount of greenhouse gases or contamination of soil and water by various types of chemicals. This bachelor thesis focuses on fine particles, which are mainly responsible for air pollution. The aim of this work is to create an overview of formation and distribution of these particles, to point out the impact of these particles on human organism and, last but not least, to show possibilities how to reduce the production of these particles or how to clean air from them.

Heat loss of buildings and proposals for measures to eliminate them
Nguyen Khac, Hoang ; Poláčik, Ján (referee) ; Baláš, Marek (advisor)
The bachelor thesis deals with calculations of heat loss in buildings and proposals of meas-urements. Thesis is divided into 5 chapters. In the first one there are reasons to insulate buildings, the process of material selection and furthermore there are descriptions of each materials used as insulation materials. In the second chapter there is the description of the model house, which is analysed in the thesis. The third one is about the calculation proce-dure. In the fourth chapter there is the proposal of reconstruction and in the last, fifth chapter there is an evaluation of reconstruction from financial standpoint.

Influence of heating water temperature on efficiency of heating system
Hliboký, Samuel ; Poláčik, Ján (referee) ; Pospíšil, Jiří (advisor)
The content of this bachelor thesis is to describe ways of increasing efficiency of heating in a family house. Thesis is divided into theoretical and practical part. The theoretical part is dealing with principle of function of gas boilers and ways of decreasing the temperature of water in heating system. The practical part of thesis includes economic-technical evaluation of replacement of standard gas boiler by condensing boiler, based on return of investment.

Autonomous energy systems
Dolinský, Filip ; Poláčik, Ján (referee) ; Pospíšil, Jiří (advisor)
Master thesis deals with usage issues of autonomous, self-sufficient and decentralized systems. In the first part convectional and experimental sources for autonomous systems are disclosed. Second chapter deals with accumulation of electrical and thermal energy and possibilities of applications. 3rd part is focused on pilot project realized for autonomous and smart systems, which were built in last years. In the 4th chapter electrical and thermal energy consumption curves are made on daily and monthly basis for 4 type objects. In the fifth part issue of autonomy is explained, and for type buildings solutions are made with additional return on investment. The last chapter is focused on calculation of thermal accumulator and briefly discloses small district heating.

Proposal heat sources for home heating
Dobai, Szabolcs ; Poláčik, Ján (referee) ; Baláš, Marek (advisor)
This bachelor’s thesis deals with heating and selection of appropriate heat sources for family houses. The first chapter describes heat sources used for heating by type of fuel. The second part is devoted to calculation of the energy balance and the amount of heat required for a particular object. According to the results, five possible options are selected. At the end, the economic evaluation of the selected heat sources are processed and the most suitable one is selected. The attachment provides floor plan, section, list of the elements (windows and front door) and also appearance of the house.

Proposal the heating system of the house
Zouhar, Adam ; Poláčik, Ján (referee) ; Baláš, Marek (advisor)
This bachelor thesis is dealing with proposals for the heating of the model house and about assessment of investments to these solutions. First, research of heating systems has been done, then the model house has been described. After that heat loss of this building and the energy needs for heating and preparing hot water have been calculated. At the end, some solutions of the heating system have been proposed. The financial comparison of these solutions has been done in the last chapter of the thesis.

Solar Energy Applications in Houses
Jankůj, Tomáš ; Špiláček, Michal (referee) ; Poláčik, Ján (advisor)
This thesis is focused on photovoltaics and photothermics. Their source is solar radiation that belongs to the category of renewable sources. At present, great emphasis is placed on ecology and economics. For this reason, renewable sources are coming to the foreground. In the first part of the bachelor thesis, types of photovoltaic cells, technology and their efficiency are presented. Furthermore, the principle and construction of photovoltaic and photothermal systems are described. The second part describes the design of the energy solution of a family house using solar energy.
