Versatile Control Unit of Solar Collectors
Tříska, Vít ; Růžička, Richard (referee) ; Šimek, Václav (advisor)
This thesis deals with design and implementation of a versatile control unit, which is primarily designed for control of solar collectors. It describes the various stages of design. First, the system of solar collectors is introduced. Its input-output parts are analyzed and the requirements are determined for the control unit. The characteristics of temperature sensors are examined, the work deals with continuous variable speed circulators. The following part is dedicated to hardware and software implementation of the objectives of the work. The boards were designed in Eagle design environment, the firmware was written in C programming language. In conclusion, the evaluation of the results of the proposed system and possible ways of its further development are discussed. The versatile control unit can be deployed in practice realistically.

Air-collector in heat balance of building
Dosedlová, Anna ; Počinková, Marcela (referee) ; Rubinová, Olga (advisor)
The subject of the thesis is the use of solar thermal technology for the production of low-potential heat. The theoretical part is focus in the solar technology, variants of passive use of solar energy. Describes in detail the solar facades, it's classification in terms of basic criteria. Applications on the project forced ventilation in administrative buildings, installation of solar facade. The work also includes an experiment that deals with the thermal behavior of the air collector.

Determination of the efficiency of solar collectors covered makrolon plates.
MATĚJKA, Jan
This thesis deals with the alternative cover of the liquid solar collector. It describes the structure of the solar collector itself and the influence of various parameters that directly affect its effectiveness. It analyses technical - economic possibilities of the usual type of the glazing and compares them with possibilities to cover the collector with the makrolon plates. The aim is to perform a theoretical evaluation to find out whether the referenced type of covers, due to its characteristics, could be used. In conclusion the evaluation of values and possibilities of its practical use are shown.
