Small-scale gas heat pump
Poul, Josef ; Kracík, Petr (referee) ; Pospíšil, Jiří (advisor)
The diploma thesis deals with the issue of gas heat pumps. It provides a general survey of heat pumps in the first part and in the second part it aims on proposing settings of a gas heat pump for the given operating parameters. The proposed concept is applied to the specific case study of deployment in the industry with subsequent economic evaluation.

Heat exchanger flu gas - water/stem for tri-generation unit based on stroke engine
Hadraba, Jiří ; Baláš, Marek (referee) ; Pospíšil, Jiří (advisor)
This diploma thesis with resolution of technical and partially economical project of combustion exchanger of cogeneration unit for application of absorbing cooling. Considered types of exchangers are: combustions/water and combustions/steam. The other capitols include the description of cogeneration, trigeneration and other possible resolutions of intersections among mentioned systems; general overview of plant oils used as a fuel in energetics, particularly in compression engines in technology of combined production of electricity and heat.

ORC cycle for waste heat utilizing
Vítek, Stanislav ; Svoboda, Pavel (referee) ; Pospíšil, Jiří (advisor)
The aim of this diploma work is the study and the modeling of an Organic Rankine Cycle (ORC). Organic Rankine Cycle is used for heat recovery from low-potential heat sources. Their working fluid is a refrigerant or a hydrocarbon whose properties are adapted to the conditions in which the heat recovery is performed. The other chapters include the technical resolution of exhaust-heat exchanger of cogeneration unit for application ORC and partially economic study use in Czech Republic.

Heat exchanger design
Vítek, Tomáš ; Lisý, Martin (referee) ; Špiláček, Michal (advisor)
This bachelor thesis deals with the design of an additional flue gas exchanger for the use of residual energy of flue gas. Part of the work is a summary of the knowledge about heat exchangers, their principle, operation and maintenance. The next part of the thesis is the calculation draft of the heat exchanger, calculation of heat transfer and subsequent calculation of hydraulic losses for the designed exchanger. Part of the bachelor thesis is a drawing documentation of the designed exchanger too.

Biomass microcogeneration unit with turbomachine
Horák, Jiří ; Fiedler, Jan (referee) ; Škorpík, Jiří (advisor)
This Master´s thesis deals with a theoretical micro cogeneration unit design contains hot air microturbine using energy from biomass. In the first part of the thesis there are model examples of energy consumption in typical family or apartment houses. In the next part there is the overview of micro cogeneration commercial units which can be used in model examples of a family or apartment housing. According to the assignment of this thesis and based on the analysis of model examples a new cogeneration system is designed. The last part of the thesis deals with the economic evaluation of the new cogeneration system compared with commercial systems.

Design of a flue gas exchanger for the use of condensation heat from flue gas
Čulík, Martin ; Burda,, Radim (referee) ; Baláš, Marek (advisor)
The subject of this thesis is the design of a flue gas exchanger for the use of condensation heat from flue gas. The first part of the thesis is rather theoretical and presents the main issues of condensation and its characteristics. Next, the necessary calculation relations for a complete thermal-hydraulic calculation are given. Using this knowledge obtained from the theoretical part, a flue gas exchanger is then designed in the practical part. Furthermore, for the same parameters, the exchanger is calculated in the PPSD program and both approaches are compared. Finally, a sensitivity analysis will be performed.
