Determination of HVAC air distribution within a passenger vehicle cabin
Planka, Michal ; Mlkvik, Marek (referee) ; Fojtlín, Miloš (advisor)
The aim of this bachelor´s thesis is to determine proportional coefficients of air distribution provided by heating, ventilating, and air conditioning system (HVAC) within a passenger vehicle cabin. The focus of this paper is to determine air flow rates from the outlets at predefined outside climatic conditions (ambient temperature and solar load). The simulation of outside climatic conditions was executed by placing the car into a climatic chamber. The air flow rates from outlets were determined by measuring air flow velocity method, specifically by determining mean value of air flow velocity profile and area of outlet crosssection. Hot-wire anemometry was used for air flow velocity measurement. The results of this experimental work are presented in a diagrammatic form and will serve as a groundwork for boundary condition setting for computer modeling of thermal load and thermal comfort within a vehicular cabin.

Artificial lung ventilation for neonates
Pohořilský, Marek ; Mlkvik, Marek (referee) ; Lízal, František (advisor)
The bachelor thesis deals with optimization of artificial lung ventilation (CPAP) aiming to achieve higher efficiency in use with neonates at neonatal intensive care unit. The content of the thesis is divided into three parts. The first part describes the basic principle of the mechanical ventilation operation, lung parenchymal disease, respiratory care of neonates and patient interface devices. The second part of the thesis focuses on research, which is divided into chapters describing calculation of pressure loss and the experiment itself. The last part outlines a comparison and evaluation of individual interface devices and recommendation of effective practical use.
