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.

Radiating shield for sensor outdoor temperature
Janáček, Adam ; Charvát, Pavel (referee) ; Štětina, Josef (advisor)
Bachelor’s thesis mentions methods for outside temperature measurement; each of this method is briefly described. Principles of outside temperature measurement, regarding placing of the temperature sensor, are shown. Importance of use of radiation shield for more precise measurement is pointed out. Radiation shield’s function and construction of aspirated and self-aspirated shield, as well as their main advantages and disadvantages are described. Market research then shows radiation shields made by their main manufacturers, each shield is briefly described. Two radiation shields, aspirated and self-aspirated, are designed, with respect to simple construction and knowledge gained during market research
