Optimalizace vybraných parametrů kompresorového chlazení v potravinářském provozu

Černý, Lukáš January 2015 (has links)
This thesis focuses on the topic of food chilled compressor-lation. The work is divided into two parts. The first part deals with the theory of compressor cooling in the food service related regulations and standards. The second part focuses on the analysis of current cooling in selected food operation and design optimization of individual parameters. Part of the second part is also an economic evaluation optimization.

Vliv režimu práce zážehového motoru na jeho tepelnou bilanci

Studený, Petr January 2017 (has links)
The diploma thesis presents a topic The Influence of the Mode of Work of a Petrol Engine on its Heat Balance. The thesis is divided into two parts. The first one is focused on the characteristics of combustion engines and on individual components of a spark-ignition engine, which are closely related to a measurement of the heat balance. Second part of the presented thesis describes methodology of the heat balance measurement on a spark-ignition engine at the motor testing institute of Department of Technology and Automobile Transport of Mendel University in Brno. It is primarily focused on change of the individual heat flow components during different loading modes and graphic representation of them.

Optimalizace chladicího systému letounů / Airplane Cooling System Optimization

Lajza, Ondřej Unknown Date (has links)
Dissertation thesis is focused on the aircraft cooling system optimization. The knowledge of the pressure loss is necessity for design of an optimal system. In the beginning of the thesis, the different designs of piston engine cooling systems are described for both aircrafts and automobiles. Other sections outline the determination of the coolers characteristics and describe the different test sections applicable for the characteristics measurement. The test section built at the Institute of the aerospace engineering is described as well. Practical part of the thesis describes the calibration of the test section. The measurements of the specific coolers were compared with the CFD simulation of two models - the simplified cooler model and cooler element model. Additionally, the measurements were compared with results obtained at specialized coolers testing facility.

Chladič vody pro stropní chlazení / Water chiller for ceiling cooling system

Havlíček, Jan January 2013 (has links)
The topic of this diploma thesis is to design water chiller for ceiling cooling system. The thesis is divided into four main parts. The first part deals with the theoretical description of emitting cooling systems. The following part focuses on the theory of refrigerating systems and describes especially the thermal cycle and refrigerants which are used in cooling systems. In the third chapter refrigerating equipment are described. Compressor, heat exchangers and expansion valves belong to the main parts of refrigerating systems. The final chapter is devoted to the draft and selection of components of the refrigerating system.
