Leak testing of pneumatic components
Staňo, Martin ; Šubrt, Kamil (referee) ; Houška, Pavel (advisor)
This diploma thesis is focused on the issue of pneumatic components testing and air leakage measurement. The current state of the given issue is summarized based on the analysis of leak testing methods in accordance with valid legislation. The aim of this thesis is to design methods for pneumatic components testing according to specification. As part of method verification, a pneumatic circuit with a pressure control system has been assembled, on which functionality tests of provided components and leak tests by the pressure-drop method have been performed. The results of these tests have been subsequently evaluated as consistent with the specification.

Testing method of car air-conditions
Bezděk, Lukáš ; Katolický, Jaroslav (referee) ; Štětina, Josef (advisor)
A topic of bachelor’s thesis is a testing of car air-conditions. The introduction shortly covers the history of the air-condition in the personal vehicle. Following chapters describe a definition of air-conditioning equipment, explaining the cooling principle, and transporting the air to the interior of the vehicle. Air-conditioning device is a complicated unit, thus there are mentioned the main circuits and components, from which the vehicle air-condition is built. The basic division is also included. There is also a big chapter that paid attention to different diagnostic methods of testing the vehicle air-conditions. This chapter follows a proposal of testing device and functional scheme of air-condition measurement. The conclusion summarizes the usage of the cooling media, its impact on environment, and new trends in area of refrigerant.

Analysis of technology for checking the tightness of manufactured heat exchangers with a focus on increasing its reliability
Grúz, Jan ; Kilkovský, Bohuslav (referee) ; Jegla, Zdeněk (advisor)
This master thesis deals with the analysis of the leakage checking technology of heat exchangers in a selected industrial company. According to this analysis the specific improvement proposals with the potential to increase the reliability of this technology are identified, selected and created. This analysis is carried out through consultations and meetings with the employees of the company and also with the help of the provided data and information. On the basis of this analysis, the technical background research of the leak testing technology and the DMAIC methodology, specific modifications with the potential to improve the operated technology are proposed and the amount of investment to implement them is estimated.
