Air Conditioning of Hotel
Vičan, Martin ; Šikula,, Ondřej (referee) ; Gebauer, Günter (advisor)
This bachelor's thesis deals with hotel ventilation. Special interest is concentrated on the common section, which is comprised of a lecture hall, a wine bar and a lounge. This project is particularly focused on thermal balance, air-flow, designing distributional elements, pipeline dimensioning, air treatment, air-handling equipment design, noise cancellation, pipeline thermal isolation and ventilation cooling.

The effect of the ventilation settings on amount of fed air and its distribution in the car cabin
Poláček, Filip ; Fojtlín, Miloš (referee) ; Pokorný, Jan (advisor)
This thesis deals with measuring of the distribution and volume of intake air inside vehicle cockpit under varying outdoor conditions and air conditioning settings. Fan characteristic was developed to determine the volume of air taken inside the cockpit. The measuring was made using speed probes in climatic chamber, where different outdoor conditions could be simulated. Following the measurements there is dependence between the air distribution and the outside temperature. The diploma thesis presents source materials to develop a mathematical model of car cabin.

Optimization of Cabin Environment in Small Transport Aircraft
Fišer, Jan ; Janotková, Eva (referee) ; Masaryk, Michal (referee) ; Patočka, Stanislav (referee) ; Jícha, Miroslav (advisor)
The thesis deals with design and optimization of environment in cabins of small transport aircrafts, especially in terms of thermal comfort and quality of ventilation. The design of air distribution systems and structural design were optimized and most important parts of cabin design with highest impact on the quality of thermal comfort and ventilation were identified based on literature research and experience of the author. The chosen modifications and their influence on the microclimate inside the cabin were investigated using the CFD model, which was validated by results obtained from measurements of flow and temperature fields in the cabin mock-up of small transport aircraft EV-55. Next optimizations were investigated: The type of air distribution system, The geometry of ducts of air distribution system, Thickness of thermal insulation and Emissivity of internal surfaces. Thermal comfort was assessed based on the methodology of the equivalent temperature and comfort zones diagram developed by H. O. Nilsson and for assessing the quality of ventilation the concept of based on index of the age of the air was used. Fifty cases were simulated in total and base of its results Modified mixing ventilation with original air ducts geometry have been evaluated as an optimum. The ducts geometry of Modified mixing ventilation system was suggested by author specially for the thesis. In combination with high thermal insulation of walls and high emissivity of the interior, then this system of ventilation ensures maximum thermal comfort and quality of ventilation for the investigated range of environmental and operational conditions.

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.

OPTIMIZATION OF WELLNESS AIR CONDITION
Kysilka, Michal ; Zubíček, Vojtěch (referee) ; Šikula, Ondřej (advisor)
The theme of diploma thesis is a design optimization of air distribution in swimming-pool hall with regard to free water surface evaporation. This problem was solved according to determined criterions with the aid of CFD simulation. Experimental measurement part of the thesis deals with evaporation problems where own formula for this physical phenomenon is determined. This formula is compared with already known algorithms. Author suggests that such formula might be integrated in CFD software.

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 in the sports facility
Sedlařík, Jakub ; Bernard, Jiří (referee) ; Rubinová, Olga (advisor)
The bachelor thesis deals with air conditioning sport object. The building is located in Znojmo. The aim was to design three air conditioning equipment for bowling, gym and sanitation. This is the air conditioning and mechanical ventilation. In the first part of the theory is mainly focused on selected objects sports facilities and sports centers microclimate. The theoretical part explain the issue halls air heating, radiant heating and air conditioning, and finally its use. After the theoretical part of the calculation follows that addresses the design of the equipment for each room.

Airconditioning of the house to the medical service
Vytasil, Michal ; Jelínek, Ondřej (referee) ; Rubina, Aleš (advisor)
This bachelor's thesis deals with the design of air conditioning equipment in the house to the medical service. The solution is the basement floor with a waiting room, reception and sanitary rooms and 1.NP with surgery. Heating load of part of the basement is completely drained air handling units, in other rooms are used sub-system with fan coil units. Sanitary rooms are exhaust ventilation ceiling-suspended equipment. In the theoretical part of the thesis focuses on the bypass factor, surface temperature of the heat sink and their effect on the dehumidification.

Air conditioning for business and sports center
Klügl, Martin ; Rubina, Aleš (referee) ; Rubinová, Olga (advisor)
This Bachelor’s thesis processes after analysis of the building design of an air-conditioning devices for three selected areas. For this devices are calculated a heat balances and an airflow. On this parameters are further suggested a distribution elements, performs a dimensions of the pipe and is designed an air-conditioning unit. The devices are above that supplemented by a fancoils. It is also solved an attenuation of a noise. In a project part is write up a project for realization of the air-conditioning devices.

Ventilation in sports facility
Frühauf, Patrik ; Šikula, Ondřej (referee) ; Rubinová, Olga (advisor)
The bachelor thesis deals with ventilation in sports facility. The objective of this work is to design two or three air-conditioning units in the part of assigned building. The bachelor thesis is divided into three main parts: theoretical part, calculation part and project.The theme for theoretical part is air distribution. Attention is especially devoted to airflow in a room, piping system and distribution elements. The calculation part is practically focused on designing of air-condition units. The last part of bachelor thesis is formed as documentation for sports facility.
