Design of heatexchanger
Nováček, Filip ; Gottvald, Jakub (referee) ; Nekvasil, Richard (advisor)
The aim of this bachelor thesis is to design a heat exchanger which will be part biogas cogeneration system. This work will be divided into two parts. The first part deals only with the known types of industrial heat exchangers, operation and maintenance. The work is not addressed the issue of transfer and exchange of heat because the thermal-hydraulic calculation was the subject of enter. In the second part is design solution heat exchanger according to given parameters controlling, the calculation of pressure parts of the heat exchanger according to ČSN EN 13445-3 and FEM calculation of the critical parts of a heat exchanger. The thesis is also the drawings forms of the heat exchanger.

Software comparison for design and control of pressure vessels
Staňková, Lucie ; Pernica, Marek (referee) ; Lošák, Pavel (advisor)
The main goal of this thesis is to compare different software for pressure vessels design and control. This comparison is done by designing a given pressure vessel, specifically a heat exchanger. The heat exchanger is designed in software Sant’Ambrogio, Visual Vessel Design and PV Elite. Advantages and disadvantages of used software are discussed. Thesis evaluates various aspects of design, particularly graphic interfaces, user-friendliness, clarity and calculated results. The results for the cylindrical shell and the torispherical end of each software are analysed and compared to own calculations based on ČSN EN 13445 design code. Differences among results are explained. Thesis also contains the literature search report of pressure vessels design.

Analysis of heat exchanger troubles
Bartošek, Nikola ; Jegla, Zdeněk (referee) ; Kilkovský, Bohuslav (advisor)
The master thesis is focused on analysis of specific cross-flow in-line tube bundle heat exchanger which deals with significant operational problems. Thermal, hydraulic and vibration calculation analysis of selected parts of the heat exchanger is performed based on CFD flow distribution results. Calculation is performed by using Maple software. Thermal and hydraulic calculations are compared with results obtained by commercial software HTRI.

Heat exchanger model
Dufek, Martin ; Hynčica, Ondřej (referee) ; Štohl, Radek (advisor)
This bachelor thesis deals with programmable logix controller ControlLogix, panel PanelView Plus, model of the heat exchanger and its components. The main goal is to suggest a model exercise for exchanger and processing of standard measurements. Model exercise is solving regulation and handling fault conditions. Visualization solves a draft and a realization within a work with the model which makes possible to monitor a state of the model in distance conditions and its controlling.

The design of the recuperative heater flue gas - air
Procházka, Tomáš ; Baláš, Marek (referee) ; Milčák, Pavel (advisor)
The bachelor s thesis deals with thermal-hydraulic calculation of recuperative gas air he- ater. Type of heat exchanger is shell and tube. This thesis is divided to two parts. The first part apprises the most common types of heat exchangers and their use. It contains also description about basic methods and equations for heat exchanger designing. The second part is calculation of heater with software EES. Whole calculation is checked by software HTRI Xchanger Suite. At the end of this thesis are two datasheets, whitch contains designing solutions for heater with plain tubes and solution with fin tubes. Conception of heat exchanger is chosen by TEMA Standards.

Parametric Study of Air Heat Exchanger
Podola, David ; Volavý, Jaroslav (referee) ; Fišer, Jan (advisor)
This diploma thesis deals with the impact of changes in operating and geometrical parameters of regenerative heat exchanger on the efficiency of decentralized ventilation units with heat recovery. Decentralized ventilation unit can be used for ventilation of family houses or smaller administration buildings. Output of this work is to determine the efficiency of a particular produced model of decentralized ventilation unit and overview of the possibilities increased efficiency of heat recovery of this units.

Present production of heat exchangers in the Czech Republic
Dvořák, Jakub ; Bělka, Miloslav (referee) ; Jaroš, Michal (advisor)
The aim of this bachelor’s thesis is to compile summary of heat exchangers manufacturers, which occurs on Czech market. In the theoretical part of this thesis is stated distribution of heat exchangers according to some basic criterions (for example flow arrangement). This distribution is followed by short explanation of how heat transfer can be realized. In the end of the theoretical part of this thesis there are presented some physical relations and their description. More practical and main part of this bachelor’s thesis contains summary of heat exchangers manufacturers and examples of their products, which are divided to some categories, mainly according to construction. At the end, there is comparison of brazed plate heat exchangers from various companies in application for preparation of hot water.

Calculation program for heat exchanger design
Švec, Dalibor ; Baláš, Marek (referee) ; Pospíšil, Jiří (advisor)
The diploma thesis is focused on creating a calculation software for designing heat exchanger. The software will not calculate one single heat exchanger but will recommend all heat exchangers which meet the requirements. Then, user can decide which heat exchanger is best suited for the specific application and make a comprehensive calculation. Part of the diploma thesis is to verify correctness of the software and make a parametric studies. Parametric studies will be focused on baffle cut, baffle spacing, tube pitch, and tube thickness and its effect on heat transfer and pressure drop.

Low-grade heat recovery in industrial processes
Novák, Michal ; Gal, Pavel (referee) ; Havlásek, Martin (advisor)
The bachelor thesis is focused on the waste heat recovery options from industrial processes. The first part is the theoretical introduction into the problematics of the heat transfer. In the next part the most common waste heat sources are presented. The third part summarizes the methods for waste heat recovery. The last, practical part presents the implementation of the waste heat recovery system into the real operation.

Designing of a hot water heater
Zdražil, Pavel ; Frömel, Zdeněk (referee) ; Baláš, Marek (advisor)
This thesis processes design of hot water heater. It was done thermal, hydraulic and basic strength calculations in the work and from their outcomes was set up a design of heat exchanger, which was afterwards modelled and drawn. In the beginning of the work is reader introduced to heat exchanger types and characteristics and also to its thermal processes. Then the work continues with thermal design of the heat exchanger, where the most important outcome is heat transfer surface with other geometric parameters, followed by hydraulic design, where pressure loss on water side was calculated. The calculations are finished up by basic strength design, calculating thickness of shell and tube walls. The thesis is ended with evaluation of computed design and description of its basic features.
