Design and comparison of a space heating systems with different heat sources in family house
Kamenský, Petr ; Elcner, Jakub (referee) ; Katolický, Jaroslav (advisor)
Diploma thesis deals with design and comparison of heating systems. In diploma thesis is designed system with gas condensing boiler, system with heat pump and system with gas condensing boiler for heating and solar collectors for heating of hot water. Content of this thesis is calculation of house heat loss, design of radiators, design of heat systems including a check of protective components, regulation with the help of thermostatic radiator valve, calculation of economical evaluation and creation of design documentation. Design is made for systems with unified temperature fall 55/45. For the variation with heat pump is computed a possibility of using the heat pump as an univalent or bivalent heat source. In the analysis of costs is considered a usage of natural gas for heating and warming of hot water with a condensing boiler, annual consumption of electric energy for operation of electrical appliances in household, consumption of electric energy for operation of heat pump for heating and warming of hot water and consumption of electric energy for warming of hot water in case of system with solar collectors. In the final evaluation a pay-off period is determined.

Economic Evaluation of Public Investment Project
Balogová, Kristina ; Vorlíčková, Petra (referee) ; Hromádka, Vít (advisor)
This thesis deals with the economic evaluation of optimalization of transport infrastructure. Aim of the thesis is to define problematics of economical evaluation of public investment projects and It’s specifics. In analytical part It describes theme of public sector, project life cycle, cost output methods and transport infrastructure evaluation. In the practical part, the project is analysed in the original variant and in case of project suspension for one year. Furthermore, there are perfomed evaluation analyses by sensitivity and quantitative analyzes for both variants.

Strength calculation of heat exchanger tubesheet with focusing on economic evaluation
Horniak, Patrik ; Vincour, Dušan (referee) ; Buzík, Jiří (advisor)
This bachelor thesis is focused on strength design of assigned shell-and-tube heat exchanger. This heat exchanger have fixed tube sheets and straight tubes. Designed tube sheet is integrated with shell and flanged to the channel. First part of the thesis serves as introduction on the issue of heat exchangers and tube sheets. Following chapters are dedicated to the strength design of tube sheet thickness based on the ČSN EN 13 445 standard. These chapters are dealing with input parameters, basic requirements of calculation, equations essential for calculation of stress in heat exchanger and analysis of stresses in heat exchanger with the use of proper strength conditions. Conclusion of these chapters is evaluation of calculated results from personal scipt written in Python language using Spyder environment. Correctness of these results is ensured by their comparison with the output of Visual Vessel Design (VVD) program. Final part of the thesis is economic evaluation of whole tube sheet design based on possibility of choosing different analyzed material.

Design of an extraction steam condensing turbine in the Precheza company.
Pavelka, Tomáš ; Paseka, Bohumil (referee) ; Bok, Jaromír (advisor)
This diploma thesis is concerned with the design of the machinery with an extraction steam condensing turbine in Precheza corp. The theoretical part of this thesis describes the energetical situation in the company and the primary consideration about recovery of the heat, released at sulphuric acid production, for electrical power production. There is also presented brief description of the sulphuric acid production and the fundamental principles of the steam production at this process. In the practical part of this thesis there is performed the calculation of the heat-flow diagram of the steam turbine and the calculation of heat and producted electrical power at the basic operational states. There is presented the source code for the calculation of the heat-flow diagram using Matlab software. In the end there is mentioned the economical evaluation of the whole project, using the fundamental economical methods, such as net present value method, or profitability index, including the calculation of the pay-back period.
