Ventilation and air conditioning of a car cabine
Viščor, Petr ; Hejčík, Jiří (referee) ; Fišer, Jan (advisor)
In this work are described kinds and functions of air-conditioning systems which are used in cars. Further is described heat transfer between car cabin and ambient environment and issue of reduction of air-conditioning energy consumption. Last part of the work contains numerical simulation made by the THESEUS-FE 2.1 software package. This simulation was done on a model of the Toyota Prius car and was focused on effect of glazing on a temperature of the air inside the car cabin during hot summer days.

Car cabin passive cooling system performance study
Viščor, Petr ; Hejčík, Jiří (referee) ; Fišer, Jan (advisor)
The work is focused on issue of passive cooling in a cabin of a car. The basic principles and mechanisms of heat transfer are described in the theoretical part and the quality of cabin environment in terms of thermal comfort and air quality is discussed as well. Next part of the work describing the principles of ventilation and air conditioning of cabins and possible methods of passive cooling are discussed. Passive cooling means decrease of temperature of cars interior, without need of energy supply from car battery, or fuel. The last part of the work includes numerical simulation of selected methods of passive cooling using the THESEUS-FE 3.0 software. Simulations were performed on model of Volkswagen Polo car and primarily were focused on testing of functionality of various methods of passive cooling.

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.

Condition and Control Active Safety
Gašpar, Daniel ; Drápal, Lubomír (referee) ; Blaťák, Ondřej (advisor)
Bachelory work concerns conditional and control safety, shows thermal conditions of car crew, obligated specifications for heating and air-conditioning. Focuses on cooling units, defines exact part of air-condition´s systém, transfer of heat between a cabin of a car and souroundings, reduction of consumption and ways of reaching of this statement. Next it is encouraged with comfortability of siting, mainly locating people in bodywork, geometry inside space and creating virtual model and constructing seats.
