Energy Recovery from Exhaust Gases in an Electric-assisted Turbocharger for Hybrid Vehicles
Calábek, Daniel ; Kudláček, Petr (referee) ; Novotný, Pavel (advisor)
Obsahem této diplomové práce byla vhodnost využití turbodmychadla s přidruženým motor-generátorem pro vybrané typy hybridních vozidel a následná analýza energetických toků pro danou motorovou aplikaci. Přístup prezentovaný v práci zahrnuje termodynamický model motoru v programu GT-SUITE ve kterém jsou zkoumány možnosti energetických toků při změně velikost turbínového a kompresorového kola turbodmychadla. Přistup je aplikován na turbodmychadlo s variabní geometrií lopatek s přidruženým motor generátorem pro donáškové vozidlo, kde je možné při různých zatíženích motoru rekuperovat energii z turbodmychadla. Zároveň byli zjištěny možnosti snížení spotřeby paliva v určitých provozních bodech motoru.

Design of ventilation system in residental spaces
Břenek, Václav ; Charvát, Pavel (referee) ; Pech, Ondřej (advisor)
This bachelor thesis deals with design of a ventilation system with recuperation in a chosen flat. The introductory chapter focuses on research of recuperation units and their parts. In the second chapter the required amount of ventilation air is determined, and three recuperation units are selected. In the third chapter the pipeline system is designed for the selected units, which is subjected to a control calculation of pressure losses. The last chapter compares the costs of implementation and operation of selected units.

BMW Up-to-date SI-engines
Šroba, Roman ; Prokop, Aleš (referee) ; Dundálek, Radim (advisor)
The Bachelor’s thesis deals with modern BMW spark-ignition engines. It provides an overview of current automotive design solutions in gasoline engines. The work is focused on three main areas. The first part describes the latest and unconventional technologies used in current BMW spark-ignition engines. The second part is focused on design solutions in specific aggregates, their evaluation or comparison with contemporary competition. The last part describes the hybrid vehicles and the car manufacturer's response to emission standards with focus on the waste heat of a car.

Ventilation of low-energy houses
Kubisz, Pavel ; Fišer, Jan (referee) ; Charvát, Pavel (advisor)
Dissertation deals with division and description progressive trends of ventilation of low-energy houses. Forasmuch as ventilation is participant in total heat consumption, It is here practical example how total heat consumption depend on ventilation heat consumption and heat consumption by construction. At the close is showed when is good, or bad, to use ventilation with recuperation.

Ventilation and cooling system for an apartment in block of flats
Uřičář, Filip ; Fišer, Jan (referee) ; Hejčík, Jiří (advisor)
This Master’s Thesis deals with the design of ventilation and cooling of an under roof flat in a tenement building, built in the 1980s, and consists of five main parts. Within the first main part, the thesis is dedicated to the research of the current state of knowledge in the area ofventilation and cooling of residential premises, secondly, there is a detailed description of a particular flat, thirdly, the calculation for the optimal design of ventilation and cooling are made and, in the fourth part, suggested solutions are proposed with the following evaluation of them including the overall summary. The design of ventilation and cooling was carried out according to the design procedures with respect to the relevant standards and optimized to achieve the desired effect with respect to the requirements of the owner of a housing unit. As a solution, the ventilation of a flat by the Jablotron Futura´s ventilating unit and three variants of a flat cooling were proposed. After the evaluation of all cooling variants, the Sinclair´s multisplit system of cooling was chosen as the most suitable one.

Study on the potential of an integrated waste-to-energy unit
Freisleben, Vít ; Turek, Vojtěch (referee) ; Jegla, Zdeněk (advisor)
This diploma thesis is focused on the design of technological modifications of the existing industrial unit „waste-to-energy“, used for thermal treatment of process waste gases containing VOC and CO while flue gas is produced. The main objective of the existing unit modification is to improve its operating parameters considering economy, ecology and energy utilization. In the first part, the current industrial plant was presented with all necessary process data. Furthermore, all the key equipment used for the waste gases treatment or for the utilization of waste heat was identified. In the main part of the thesis there are performed modifications of the existing unit including the technology of existing heat exchangers intensification, the design of new and more efficient heat exchangers and finally the catalytic oxidation technology implementation for the decomposition of pollutants contained in the waste gas. The result of the thesis is a technical, economic and ecological comparison of the proposed technological modifications with the existing operation.
