The use of solar collectors in the Czech Republic
Kočka, Jan ; Kic, Pavel (advisor) ; Vaculík, Petr (referee)
The aim of this thesis was to approach the market of solar systems in the Czech Republic and the subsequent design of the solar system in the selected object, in this case RD Divišov. In the chapter Overview of the findings from the literature there are outlined the general knowledge about the Sun and the use of solar radiation. In addition, this chapter provides a general overview of solar collectors followed by the approach of the necessary elements for the functioning of the solar systems. In the chapter Default conditions of the solved object there is characterized the selected one, and there is described the current system in this object. Chapter The design of the solar system in a given object includes the proposal of individual elements of the solar set for water heating. There are compared variants with different demands, different input parameters on the basis of values and graphs chosen the most efficient option for this project. At the end, the economic evaluation of the proposed system with the subsequent comparison with the current system and possible return. The work is ended by summarizing of the whole issue.
