Solar heating tap water
Kysel, Stanislav ; Pospíšil, Jiří (referee) ; Fiedler, Jan (advisor)
Solar heating tap water In this bachelor´s work I engage in problems and concept of solar system for preparing warm supply water. For heating – up has been used a bivalent system complemented by electric heating inlet. The calculation has been intent on concept of collector area size and size of the supply bin.

Multiparameter circulating pump driver
Pazour, Zbyněk ; Frýza, Tomáš (referee) ; Kratochvíl, Tomáš (advisor)
This master’s thesis deals with design of the regulation of a circulating pump in a solar system for heating of supply water and design of the regulator for this system. It describes a fundamental principle and layout of a regulated circuit of a heating system. Description of regulation, basic terms, properties and differences between different types of regulation are described in first part of the master’s project. Especially continuous (PID regulator) and discrete (PSD regulator) regulation are presented. Second part of the master’s project is focused on a conceptual design of the circulating pump regulator. The connection system of each part, selection conditions of components and connection scheme of regulator are described. The third section deals with design of controlling algorithm of the regulator. There is a detailed description of libraries and functions in each chapter which were used in programming of PSD regulator algorithm. The regulated system of a solar collector is described at the end of the work. This system is being developed for real testing and setting of regulator.

Design of a heating system of a new apartment building
Kaša, Filip ; Maurerová, Lenka (referee) ; Vyhlídalová, Karolína (advisor)
The bachelor's thesis aims to design heating and hot water heating of a new apartment building in Nové Město na Moravě. The building has one underground floor and four above-ground floors. Heating is designed only for the upper floors, where there are living spaces. The sharing of heat into the space is ensured by plate radiators, tubular radiators and floor convectors. The system is designed in copper piping, as a hot water two-pipe. The system is powered by three gas condensing boilers. Hot water is heated by a storage heater.

Auxiliary inverters for electric traction
Polášek, Petr ; Pazdera, Ivo (referee) ; Červinka, Dalibor (advisor)
This thesis concerns with specified problems of an electric traction. It deals with the concept of module controlling EC motor of the voltage 24V and the current 100A. There are described possibilities and principles of controlling EC motor in detail. For controlling, the single-purpose IO MC33035, which is directly specified for it, is used. The thesis describes implementation of both testing and final versions of converter for a circulating pump drive of a cooling circuit in locomotives. The convertor is partly universal and can be used in other applications. According to the implemented convertor, a laboratory test and a model protocol were made. In the second part, the concept is described as well as the implementation of DC/DC conventor of output voltage of 24V and which is supplied by 12V battery. The specified output current is 4A. It is used for supplying of the controlling traction vehicle unit and is installed as a boost convertor which contains a resonance conventor. The presentation of measured parameters of the complete convertor is either a part of this thesis.

Comparison of Hydraulic Conditions in Primary Heating Networks
Mudrá, Martina ; Takács, Ján
The paper deals with the comparison of hydraulic conditions in the primary heating network of a selected section of the district heating system. The calculated state was compared with the actual state before the renovation of buildings and the calculated state with the expected state after the renovation of buildings connected to the district heating system. The aim of the paper is to point out the disproportions that exist in the real heating networks of district heating systems through pressure diagrams, as the hydraulics of the outer part of the heating system are not given sufficient attention. By reconstructing the original primary heat distribution and replacing the circulation pump on a selected section, hydraulic stability of the system and savings in operating costs can be achieved.
