Experimental assessment of distribution elements in air conditioning
Novotný, Jan ; Blasinski, Petr (referee) ; Rubina, Aleš (advisor)
The subject of this thesis is the analysis of the ventilation of the locker rooms in a hockey hall. The thesis is divided into three parts: theoretical computational part, experimental measurements and assessment of the observed data. In the theoretical part the problems of indoor microclimate, air distribution, diffusor and their flow patterns are discussed in detail. Furthermore, the procedure of using CFD simulations is mentioned. In the computational part, the thesis focuses on the optimization of the diffusors in a hockey locker room using CFD simulations. Four variants of implementation are addressed, including the original design. These variants are then compared in terms of air velocity at the entrance to the residence zone and the age of the air in the selected hockey dressing room. Finally, the presented optimal ventilation option is then evaluated. Experimental measurements are focused on the verification of the CFD simulations. The ability of the elements to provide thermal comfort is also investigated.

Air Distribution in residence ventilation system
Štencel, Bedřich ; Rubina,, Aleš (referee) ; Rubinová, Olga (advisor)
My thesis is divided into three separate parts. The first part is devoted to the theoretical part of the ventilation systems. The second part deals with the determination of the conditions for a number of air exchange, a comparison of three variants of the location of air outlets in dwelling units and the application image airflow from experimental measurements on the common room. The third part is focused on the description of the experimental tasks in the laboratory at the Institute building services.

Ventilation of classrooms at school
Kadlček, Ondřej ; Blasinski, Petr (referee) ; Uher, Pavel (advisor)
This master’s thesis deals with CFD simulation of air flow in a primary school classroom. The aim of the simulation is to evaluate the results of the proposed solution and the created other variants of air distribution with the evaluation of the proposed measures and solutions. Part of the master’s thesis is the design of elementary school ventilation systems at the level of implementation documentation.

Airconditin of guesthouse
Miesler, Zdeněk ; Rubinová, Olga (referee) ; Uher, Pavel (advisor)
My bachelor thesis follows up to design two air-conditiong units for a pension. The fist unit is used to supply and remove of air with cooling, the second unit is used to the accommodation part of the pension on the second floor. In the project, there is the calculation of the heat balances of all solved rooms, air flows, the design of the indivi-dual distribution elements, the design of pipes, the design of units with the reduction of the noise to the required values.

Air handling units
Cakl, Dominik ; Blasinski, Petr (referee) ; Rubina, Aleš (advisor)
The diploma thesis deals with the analysis of problems of unevenly stratified air flow in air handling units and subsequent optimization with respect to speed ratios, energy efficiency and legislative requirements. Methods of solving the problem are theoretical and experimental, while the theoretical part deals with air distribution by means of air-conditioning fans with a focus on their aerodynamics, pressure conditions and other requirements, which are an integral part of properly designed equipment. In the experimental part of the thesis was applied a proposal of an innovative technical approach to a specific model of air conditioning assembly, which was implemented in the laboratories of the Institute of Building Services.

Experimental determination of the characteristics of air flow The distribution of elements
Ekl, Martin ; Rubinová, Olga (referee) ; Horák, Petr (advisor)
The thesis is aimed at the problem of the air distribution in buildings. The object of research is the concert hall. The thesis contains three different technical proposals and technical views of the microclimate concert hall. The microclimate’s solutions are focused on the air distribution in the hall. The part of the thesis is an experiment. The experiment continues on the one of the technical proposals. Its purpose is to determine the characteristics of air flowing from distribution element.

Air conditioning design in multifunctional sports hall
Navrátil, Radek ; Uher, Pavel (referee) ; Blasinski, Petr (advisor)
The diploma thesis deals with the design of air-conditioning equipment in the building of a multifunctional hall in Brno and also includes an experimental analysis of air flow. It consists of 3 parts. In the first part a theory of air distribution is elaborated. The second part deals with the analysis of air flow for different types of air diffusers and for one diffuser further looks for a simplified model. The last part of this work is focused on the design of air conditioning equipment in the assigned building, the multifunctional sports hall.
