Air Conditioning of Hotel Komplex
Očkan, Tomáš ; Děckuláček, Zbyněk (referee) ; Gebauer, Günter (advisor)
The first part of the thesis is aimed on creating internal microclimate of the hotel complex by air conditioning systems. The choice of systems is based on theoretical knowledge’s and practical application in abroad. In the second part there is designed solution for hotel apartments and conference hall. The other areas are designed only conceptual. Technical solutions of chosen systems are the main outcome of the thesis. In the third part there are published my experimental measurements from laboratories of Oulu University of Applied Sciences. For the study field of Air Conditioning has been chosen Air Flow Measurement and Test Operation of HVAC unit. For the study field of Renewable Energy has been chosen the Heat Pump and for study field of Refrigeration has been chosen Water Cooling and Chiller Box.

Cooling system for Industry 4 demonstrator
Cviček, Pavel ; Benešl, Tomáš (referee) ; Kaczmarczyk, Václav (advisor)
The aim of the bachelor thesis is to design and implement a cooling system that will be able to distribute a cooled medium. The individual parts will deal with the description and design of equipment, as well as the selection of components, including electrical ones. It will also include a description of the implementation of the equipment and the control program that will ensure the proper operation of the system. One of the goals is to create a virtual model that will serve for accurate design and also as a check whether all predetermined and required parameters for construction have been complied with. Finally, the work of the system as a whole will be evaluated.

CI-engines for Army Purposes
Šebesta, Radek ; Svída, David (referee) ; Dundálek, Radim (advisor)
The bachelor's thesis deals with utilization of compression-ignition engine in army purposes, especially in army vehicles . It aims to motors of military and special vehicles as are armoured vehicles or tanks and gives view of features about motors and exigencies which must fullfils usage in specific conditions. Thesis describes problematics of operating and maintanance CI - engines and negative effects which appear in battle contidionts. It gives notice about curing methods each parts of engine and about systems which supports engine working and classifies exemplifications of differences distinct from ordinary motors, common uses in civil cars. Creates view on problematics of positioning and constructional solution of motor space inside vehicle. It brings basic informations about oil fuels used in army and its requierements. Objective of this thesis is disclosure of information about specific features and standards of motors intended for army purposes.

Formula Student Cooling System
Marek, Jiří ; Šebela, Kamil (referee) ; Janoušek, Michal (advisor)
The bachelor’s thesis deals with Formula Student cooling system, analysis of the current cooling system, it’s construction and possibilites for it’s improvements. Based on the research of Formula Student cooling systems, the water radiator was implemented into rear double diffuser in order to support aerodynamics and other important parameters for overal vehicle dynamics. Some of the computational resources were supplied by the project "e-Infrastruktura CZ" (e-INFRA LM2018140) provided within the program Projects of Large Research, Development and Innovations Infrastructures.

Production technology flexible plastic clip
Mikulenka, Martin ; Kebrle, Ondřej (referee) ; Kandus, Bohumil (advisor)
Currently, the plastics industry has a wide range of applications due to the possibility of a fully automated process or through increased production efficiencies. The reason for this choice of the thesis was to understand the whole issue of plastic injection molding process. The specified component is used to atach the sail, which serves to protect workers in the welding sector. A specified number of the series is 350 000. The work includes a theoretical problem of injection molding process, selection of technology, material selection and design of mold. An integral part of every design mold is a simulation of injection, which is also included. In conclusion of thesis is the calculation of the various stages of production and operation of the injection mold.
