Utilization of solar energy for heating and ventilation – warm-air systems
Pospíšil, David ; Fišer, Jan (referee) ; Jaroš, Michal (advisor)
Bachelor’s thesis considers summary of application trends with using warm-air systems to space heating and ventilation. Thesis is divided into several sections. The introduction to the topic presents basic facts about solar energy; the origin of it and its availability. The next part defines systems working with solar energy for space heating and ventilation, describes partition of these systems and explains working principles. The final part gives examples in system’s application.

Heat exchangers for air-conditioning
Pavlíček, Michal ; Jaroš, Michal (referee) ; Hejčík, Jiří (advisor)
The thesis is divided into 2 parts. The first part deals with classification and characterization of heat exchangers. The sizing process of plate heat exchangers is described and demonstrated in the second part. Obtained results are compared with real plate heat exchanger produced by Güntner Company.

Heat exchangers for heating
Blažek, Miroslav ; Hejčík, Jiří (referee) ; Jaroš, Michal (advisor)
The Heat exchangers are important part in the energy transfer between two substances. Bachelor’s thesis deals with the problems of the option of the heat exchangers. It seperated into two parts. In the first theoretic part there are shown the basic criteria of this option. The next part deals with the most frequent types of usage of heating units or convectors.

Utilization of solar energy for heating and ventilation – solar façades
Mazáč, Ondřej ; Fišer, Jan (referee) ; Jaroš, Michal (advisor)
The objective of bachelor´s thesis „The Usage of Solar Energy for Heating and Ventilation – The Solar Facades“ is the description of nowadays used types of solar facades, the examination of their technical parameters and the estimation of theoretical project on chosen building. The first part is focused on general description of solar radiation, the possibility of its usage in the solar system and and the explanation of its principle. The division of solar facades in terms of their basic criteria is described in the next part. The last part deals with particular estimation of buildings which uses the passive solar system in form of the solar Facade.

Use of thermal solar collectors for pool heating – design of application
Zatočilová, Aneta ; Košner, Jan (referee) ; Jaroš, Michal (advisor)
The objective of this bachelor’s thesis is to evaluate the possibilities of using solar collectors for swimming pool heating. The solar pool heating is often combined with solar water heating. The thesis examine technical parameters, effectivity and purchase cost of the thermal solar systems for both mentioned applications. The first part of the study is focused on general description of the solar radiation, its availability and potential of usage. The next part is dealing with collectors’ energy budget, their efficiency and means of their insulation. Further, there are described the most used types of the thermal solar collectors and various constructions of the thermal solar systems of nowadays. The last part is dedicated to specific project of thermal solar system for pool heating and its price budget.

Ideal cycles of internal combustion engines
Polívka, Radek ; Jaroš, Michal (referee) ; Štětina, Josef (advisor)
During the development of cars, two main basic types of internal combustion engines have been detached: diesel engines and petrol engines. The aim of the thesis is to make an analysis of ideal cycles of these engines (graphic scheme, derivation of valid formulas, characteristics quantities, etc.), with insist on the most important of parameters-thermal efficiency and then compare their advantages and disadvantages.

Earth heat sources for heat pumps – flat collectors
Houdek, Milan ; Štětina, Josef (referee) ; Jaroš, Michal (advisor)
The aim of this bachelor’s thesis is to summarize the types of flat collectors and to compare them with the other sources of heat for heat pumps from the investment standpoint. Then to compare this kind of heating with the other kinds of heat sources for households in light of investment and operation costs. Finally, to find out usability of this heating source based on above-mentioned criterions.
