Low-temperature biogas purification
Hřebíček, Martin ; Fiedler, Jan (referee) ; Pospíšil, Jiří (advisor)
The aim of this thesis is the issue of low-temperature cleaning of biogas. He briefly acquaint the reader with the technology of production of biogas and its possible use. Provide requirements for low-temperature treatment and purification of biogas to the needs of downstream equipment. Provide an overview of the possibilities of suitable production systems applicable cold. Develop your own design facilities for low-temperature treatment of biogas

Minimization of residual stresses for rolled long products
Kubík, Petr ; Raudenský, Miroslav (referee) ; Petruška, Jindřich (advisor)
This thesis deals with simulation of cooling of rail during its passing through cooling device which has been designed by the heat transfer and fluid flow laboratory. Inputs of the computational model have been set up to get best possible correspondence between outputs of the computational model and results of experimental measurement. The solution with using of model of austenitic stainless steel is provided in first part of the thesis. The solution with considering model of carbon steel is performed in next part. Using of model of carbon steel allows including evolution of latent heat during phase changing. A fields of residual stress has been calculated for different cooling conditions in the last part of this thesis.

Design of chiller for specific application
Gaverník, Michal ; Kohoutek, Josef (referee) ; Jegla, Zdeněk (advisor)
This diploma thesis deals with design of chiller for specific aplication – The City Theatre in Brno. The solving equipment of cooling appliance includes complete design of heat exchanger, battery cold and dimensioning of pipeline system used for various media. One part of design is also choice of individual coolant pumps, which guarantee necessary cirkulation of cooling medium in a certain pipeline routes. Selected battery cold in this administration reduced the size of the necessary cooling resources, therefore the cost of implementation. Everything is processed in calculating software. The resulting proposal is also drafted in the design program and will serve as one of the bases for subsequent implementation.

Refrigeration systems in the food industry
Dvořák, Josef ; Katolický, Jaroslav (referee) ; Štětina, Josef (advisor)
Bachelor´s thesis is aimed at refrigeration systems in the industry which are used mainly in the food industry. Here are described individual parts that are refrigeration systems assembled. The work also contains summary of the ways you can make use of waste heat and also factors that have impact on economy of operation. The aim of work is to describe the basic analysis of thermodynamic cycles in the refrigeration systems which are displayed on the illustrative diagrams.
