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.

Shock Absorber for Generating of Electrical Energy
Maťaš, Marek ; Vetiška, Jan (referee) ; Hadaš, Zdeněk (advisor)
This these is considering with possibilities of generation of electric energy, with use of linear generator in automotive industry, that linear generator is replacing shock absorber. Subsequently the base model of shock absorber is used and excited with sinus signal. From this simulations are got the results of damping and power. Then it will be made a simulation of shock absorber, with known parameters of damping, mass of vehicle and real model of road. Then it is made control with PID regulator.

The use of greywater and rainwater for public facilities
Korytář, Ivo ; Raček, Jakub (referee) ; Raclavský, Jaroslav (advisor)
This paper analyzes the usage of grey and rain water in civic amenities. Its main goal is to assess the advantages and disadvantages of the grey and rain water and to dissect the problematic of rain water quality. In order to reach its goal, the current paper will analyze the already applied system of using grey water, specifically in the case of MOSAIC HOUSE in Prague, which was the first in the Czech Republic and second in the world to use grey water for heat purposes. In conclusion, this Bachelor’s paper presents one object of civic amenities, specifically the guesthouse U Cerneho psa in Cesky Krumlov, with the proposal of grey water purifier by ASIO s.r.o. and grey water seepage object from the same company together with a projected balance sheet.

Heating and ventilation in the "Doubrava" family house
Jirsová, Tereza ; Pech, Ondřej (referee) ; Charvát, Pavel (advisor)
The diploma thesis is focused on the design of heating and forced ventilation for the project of the family house Doubrava. In the first two chapters is briefly described the theory and there is also described the project of the family house. The next chapter deals with the design of the forced equal pressure ventilation with the heat and moisture recovery. Than the heat loss are calculated according to the norm ČSN EN 12831-1. The next part is focused on the design of heating system and the heat source for the family house Doubrava. There is described detailed design of the floor heating, including necessary calculations, and also the type of the heat pump, as the heat source and source for hot water heating, is chosen. This part also contains a selection of expansion tank and safety valve and approximate calculation of the size of the primar circuit. The last part deals with the possibilities of using renewable energy sources. At the end of the thesis, there are more detailed results of the calculations and the mechanical drawings of individual designs of the ventilation and heating system and also there are tables of the acquisition costs.

Exhaust Gas Energy Recuperation in a Commercial Vehicle Diesel Engine
Šroba, Roman ; Janoušek, Michal (referee) ; Vondrák, Adam (advisor)
The scope of this thesis investigates value added by a turbocharger with an associated motor-generator unit to a diesel engine used by a commercial vehicle. A thermodynamic model of the engine was prepared in GT-SUITE software. Case studies were primary focused on a reduction of specific fuel consumption as well as a nitrogen oxides production using an energy recuperation of exhaust gas. Furthermore, there are described potential benefits of using an electric assistance in order to increase an exhaust gas temperature during a steady state engine operation. Additionally, there is an investigation of potential benefits of a turbocharger assistance in a transition engine mode operating during rapid acceleration of the vehicle. The results of individual analysis will be taken into account for a selection of turbocharger regarding specific engine implementation. The results of simulation suggest that it is possible to lower specific fuel consumption, production of nitrogen oxides, as well as accelerate turbocharger response.

Energy passive kindergarten
Zelenka, Tomáš ; Kalánek, Jiří (referee) ; Ostrý, Milan (advisor)
The subject of the diploma thesis is a design of a kindergarten in a passive standard standing on a plot situated in the center of Fulnek. The building has two floors and the first floor is embedded in the terrain. The vertical load-bearing structures consist of sand-lime masonry with a contact thermal insulation system. The building is based on foundation strips due to the type of subsoil. The roofing is then solved by a single-layer flat roof with a vegetation layer.
