Ventilation and cooling system for an apartment in block of flats
Uřičář, Filip ; Fišer, Jan (referee) ; Hejčík, Jiří (advisor)
This Master’s Thesis deals with the design of ventilation and cooling of an under roof flat in a tenement building, built in the 1980s, and consists of five main parts. Within the first main part, the thesis is dedicated to the research of the current state of knowledge in the area ofventilation and cooling of residential premises, secondly, there is a detailed description of a particular flat, thirdly, the calculation for the optimal design of ventilation and cooling are made and, in the fourth part, suggested solutions are proposed with the following evaluation of them including the overall summary. The design of ventilation and cooling was carried out according to the design procedures with respect to the relevant standards and optimized to achieve the desired effect with respect to the requirements of the owner of a housing unit. As a solution, the ventilation of a flat by the Jablotron Futura´s ventilating unit and three variants of a flat cooling were proposed. After the evaluation of all cooling variants, the Sinclair´s multisplit system of cooling was chosen as the most suitable one.

Experimental study of turbulence downstream of a wire mesh
Uřičář, Filip ; Pech, Ondřej (referee) ; Lízal, František (advisor)
This bachelor's thesis is focused on the convection behind a mesh grid and consists of three parts. The first part presents current of knowledge in the generation and damping of the turbulence by the mesh grid. The second part presents experimental results of the measurement. The third part of the thesis is focused on experimental data processing and analysis. The method of hot wire anemometry was chosen for the speed measurement, namely Streamline by Dantec and for experimental purposes track had been constructed in the Laboratory of Ventilation Systems at the Faculty of Mechanical Engineering, Brno University of Technology. Based on the knowledge gained from the study of literature and the consultations, calculations and technical possibilities of the instruments used, grid measurements were performed for convection from 150 to 300 liters per minute, which was sufficient to generate turbulent flow. For the experiment, a solid grid through which the fluid flows has been chosen, due to feasibility of the experiment.
