Heat pumps for heating and hot service water preparation
Valášek, Martin ; Hrnčířová, Michaela (referee) ; Kracík, Petr (advisor)
This bachelor’s thesis is aimed to describe heating and water warming in the detached houses by basic technical devices and there are suggested various types of heat pumps for a particular object. These heat pumps are compared technically and economically. In the beginning of the thesis there is a summary of the possible ways of the house heating and water warming systems, such as heating by electric power, by gas, by solid fuel or the centrally distributed heating. Then the thesis concentrates on heat pumps. There are described various types of heat pumps, also their advantages and disadvantages. There were chosen four main types of heat pumps – air/water, air/air, water/water and earth/water – and with each type there’s constructed a plan for a low-energy house heating. This house is located in Vyškov and there’s thermal loss of 6 kWh and water-warming of a capacity of 260 l per day. At last there were used economical calculations, which shown, that the water/water heat pump has the shortest return rate in comparison with a gas-using heating system – 5 years. Considering the lifespan of the heat pumps – 10-20 years – all the heat pumps are profitable except for the air/air heat pump. The investment in this heat pump doesn’t return.

Solar heating tap water
Kracík, Petr ; Baláš, Marek (referee) ; Fiedler, Jan (advisor)
This bachelor thesis deals with the heating of hot service water by means of solar energy through solar collectors. At the beginning the author describes the most frequent methods for heating of service water in Czech houses with the help of electrical energy, fossil fuel, gas and central heat supply, including the input expenses for buying equipment. The author describes a solar system and his basic elements and suggests two variants with supplement heating by means of electrical energy, which compares with electrical heating of service water. The overall thesis is conceived as a review of possibilities of heating hot service water in households with economical budget at the end of the work.

Flow Measurement of Hot Dusty Gas
Dostál, Jiří ; Štohl, Radek (referee) ; Šedivá, Soňa (advisor)
The bachelor thesis deals with the measurement of hot dusty gas. The introduction outlines the problems of measurement. Another part of the work contains a theoretical introduction to the measurement of gas flow. In successive chapters the basic principles and characteristics of suitable methods for measuring the hot dusty gases are described. Finally, the function blocks are implemented in the Simatic STEP7 for calculation of volume flow rate and blocks are tested on PLC.
