Solar collectors with vacuum tubes
Petruška, Bohumil ; Katolický, Jaroslav (referee) ; Jaroš, Michal (advisor)
This thesis deals with solar collectors with vacuum tubes. The first part is focused on describing the function of the collectors, comparing with other types of solar collectors followed by specifications of their usage. Another topic is the heat transfer fluid that is used for transmission of heat, and therefore it is an important component of a collector. The last part deals with an application concept of use of a vacuum tube solar collector, including basic energetic and economic calculation.

Design of solar system for family house
Kundrát, Roman ; Katolický, Jaroslav (referee) ; Jaroš, Michal (advisor)
Objective of this thesis is the design of solar collector and its parameters for a designated family house with regard to the different uses of heat coming into the system in the form of sunlight. Based on literature studies, experience and advice of experts is at work introduced the concept of design of the solar system and its basic parts. Introduction of the sunlight and current technologies for processing and elements of the system priors the actual design of solar system.

Statistical processing of data of solar radiation in place BUT FME Brno
Nečasová, Klára ; Jaroš, Michal (referee) ; Štětina, Josef (advisor)
This bachelor’s thesis deals with the measurement of solar radiation. The aim of this work is to determine the usefulness of solar energy and solar radiation compared to the oblique and horizontal surface. You are given basic information about solar radiation, the Solar, collectors and sensors. Further work includes measurements and calculations of solar radiation in the course of one year and at the end of the evaluation of measurement results.

Data acquisition of solar radiation and calibration
Knapčík, Lukáš ; Jaroš, Michal (referee) ; Štětina, Josef (advisor)
Bachelor’s thesis is focused on description sensors of solar radiation, main principles, function and reason of rise mistakes and faults during the measurement. At the end of thesis is performed calibration of two cheaper pyranometers SG002 from Czech producer by comparison to a reference pyranometer CM11, which represent the secondary standard. Calibration consists of two main parts. In the first part is necessary to determine offset and in the second part to specify an instrument transferring constant between the correct and calibrated value.

An advancement of heating plants system in Brno
Brabec, Vít ; Lízal, František (referee) ; Jaroš, Michal (advisor)
The content of this bachelor’s thesis is the examination of the advancement of heating plants system in Brno. The first part of the thesis introduces a brief overview of an eighty-year history of heating industry in Brno from the first ideas up to the current state. Next part closely describes the individual plants and the system of centralized heat supply. The last section compares heat supply through steam and hydrothermal pipe-line and its influence on the combined production of heat and electrical energy.

An assessment of returnability of solar collectors installation in low-energy family house
Hrbata, Jiří ; Pešek, Martin (referee) ; Jaroš, Michal (advisor)
Increasing of standard of living, automation and mechanization of production and industrial growth lead into energy need growth. At the same time the energy prices continuously rise and it is still more preferable to use renewable energy, particularly solar radiation. This thesis contains basic information about usefulness of solar radiation, solar collectors and ways of their integration into heating systems. Particularly, it deals with the assessment of returnability of solar collectors instalation in the low energy family house. It contains calculations of necessary heat for heating, hot water heating and energy gains from solar collectors. Returnability assessment is demonstrated on concrete example.
