Substitution of district heating by gas boiler
Dobiáš, Ladislav ; Skála, Zdeněk (referee) ; Pospíšil, Jiří (advisor)
In this work, there is an overview of the design concept of condensing boilers and types of heat pumps. The current state of heating in company is assessed and possible variants are given for techno-economic evaluation. For boiler room with the gas boiler is prepared a proposal with condensation boiler. For parameters are designed and calculated proposals to form a condensing boiler. The end of the work is focused on the advantages of gas boiler and heat pump.

Comparison of traditional and nontraditional cycles of heat engines
Dobiáš, Ladislav ; Jedelský, Jan (referee) ; Štětina, Josef (advisor)
The bachelor thesis describes the thermodynamic cycles of four-stroke spark ignition (SI) and compression ignition (CI) engine, Wankel engine and two-stroke spark ignition (SI) engine. Based on the information is compared with thermal efficiency of each engines with four-stroke spark ignition engine in the T-S diagrams. There were also dedicated to Atkinson cycle and its use in practice. The last part deals with the construction of a variable compression ratio used in the development of modern engines.
