Simulation of air valves and difusers
Bombera, Jiří ; Rubinová, Olga (referee) ; Uher, Pavel (advisor)
The aim of the diploma thesis is the simulation of air valves and difusers using CFD. The goal of this thesis is to determinate the type of air valve and diffusor, which would ventilate the room of a detached house the best – considering the speed of the airflow and the age of the air. Outcome of this work is the design of the air conditioning system for a detached house with application of the air valve and difuser which is evaluated as the ideal option for the ventilation in the room.

Environmental design of the kindergarten building
Velísková, Jana ; Rubinová, Olga (referee) ; Uher, Pavel (advisor)
This thesis deals with the design of a kindergarten building in the village of Dolní Lhota.It is designed as a two-storey building with a flat roof. It will be connected to the existing primary school building. The first floor will be used for kindergarten purposes, the second floor will be used for afternoon activities. The first floor will house a classroom, toilets for children, cloakroom, offices, cleaning facilities, storage, utility room, mechanical room. On the second floor there are two classrooms for afternoon activities, a cloakroom, office, storage and toilets. It consists of three parts. The first part deals with the design of the building structure. It contains the project documentation with all floor plans, sections, foundations, roof drawing, technical report, views. The structural system of the building is a wall system. The perimeter and internal load-bearing masonry is designed in ceramic blocks. The ceilings are made of spiroll panels. The second part contains the technical equipment of the building. Design of the air handling unit and distribution elements to the rooms. Calculation of rainwater utilisation. It also includes the design of the building heating, lighting and a drawing of the global scheme. Photovoltaic panels are proposed on the roof to cover the building's consumption. Heating is provided by groundwater In the third part I discuss the effect of zoning a building. I used the design of air handling units as an example. Given the use of a school building, where the first floor will run mostly in the morning and the second in the afternoon, I looked at which option is more economical

Heat exchangers
Kuráňová, Helena ; Rubinová, Olga (referee) ; Uher, Pavel (advisor)
The master thesis deals with the issue of heat recovery and efficiency of exchangers. The experimental part is dedicated to the measurment of efficiency of a plastic model of heat exchanger with atypical construction compared to a standard plate heat exchanger. For production of the heat exchangers 3D printer was used so the thesis uses the possibilities that 3D printing is offering nowadays.

Environmental solution of a house with a café in Zaječí
Medková, Tereza ; Uher, Pavel (referee) ; Rubina, Aleš (advisor)
In my master's project I design a nearly zero energy consumption house with a café in Zaječí. The 1ST part of this project deals with a structural part of the building, which has two above-ground floors and basement. On the basement are storerooms and rooms for technical equipment, on the ground floor is café and living room with kitchen, and on the second floor are bedrooms, bathrooms and cloakrooms. Footings are from cast-in-place concrete, the load bearing walls on basement are from formwork blocks with cast-in-place concrete, on above-ground floors are from ceramic blocks and every non-load bearing walls are also from ceramic blocks. On whole floor are reinforced concrete floor slab and flat green roof. The 2ND part deals with technical equipment of the building. There are gas boiler, floor heating, air conditioning, mechanical ventilation (HVAC), photovoltaics panels with energy storage, retention tank, external blinds and biodynamic lighting. The 3RD part compares several options for using solar energy in combination with different heat sources in terms of energy and economic efficiency of the building.

Air conditioning in the library
Pospíšilová, Lucie ; Uher, Pavel (referee) ; Blasinski, Petr (advisor)
Dissertation offers a plan for air – conditioning equipment of library building in Brno and it involves air filter experimental measurement. The proposal is divided into three parts. The first part explains air filter theory with detailed description of atmospheric air filters for separation of particles for general ventilation - filter parameter determination. Theory part ends specifically with pocket air filters and their construction. The second part focuses on experimental pocket air filter measurement execution, which calculates with variable filter cartridges and pocket count. Measurement also evaluates pressure drop and their efficiency. The last part of the dissertation looks at air – conditioning equipment design for specified building, concretely library building. The project solves fresh air traffic into interior of selected library rooms and it counts with thermal heat gain in summer season, heat loss in winter season and air humidity modification.

Ventilation of sports hall
Urban, Ondřej ; Blasinski, Petr (referee) ; Uher, Pavel (advisor)
The master thesis deals with flow modeling in the CFD program. By means of which the opti-mal version of the air distribution diffuser in the sports hall will be selected. The first variant will bring fresh air through textile diffusers. The second variant will bring fresh air through flooded large circular diffusers. The tested parameter of the indoor environment will be the flow velocity and the age of the air. The better-performing version will be processed as an implementation documentation.

Acoustic emissions of buildings
Smažinka, Josef ; Uher, Pavel (referee) ; Rubinová, Olga (advisor)
The diploma thesis deals with acoustics with the main focus on acoustic emissions of buildings. The first part of the thesis aims to familiarize the reader with the field of acoustics as a whole. They will learn the basic concepts, quantities and relations that exist in acoustics. In the second part I focus specifically on the sources of noise in buildings and their surroundings, how can excessive noise affect health, what standards must be met and how to prevent excessive noise. The last part is devoted to practical measurements in the field, which is focused on real sources of noise in the city of Brno. The aim of this measurement is to compare the noise generated by buildings with other noises in the urban environment.

Application personalized Ventilation in Air Conditioning
Musil, Marek ; Uher, Pavel (referee) ; Rubinová, Olga (advisor)
The subject of this thesis is the application of personalized ventilation in air. The main aim of the work is to construct physical models of artificial ventilation outlets for personal and their experimental verification in the laboratory. The information obtained from experimental measurements are applied in the design of forced personal ventilation to the specified building. Result of this work is to evaluate the use of personalized ventilation for practice with these advantages and disadvantages.

Application and evaluation of energy enthalpy heat exchanger
Jetelina, Michal ; Horák, Petr (referee) ; Uher, Pavel (advisor)
This master thesis is solving measuring the efficiency heat recovery and application unit, which includes heat recovery into selected building. In the first part of the thesis are analy-zed the different types of heat recovery system, their behavior and suitability of use in HVAC systems. The second part includes the actual experiment, when were measured parameters of air, which passed through the unit and then were analyzed the results. In the last part, third, was measured unit applied to the selected house and was compared to operation of the unit in case of use by the producer given unit parameters and measured parameters.

Indoor pool ventilation
Hrabová, Kristýna ; Uher, Pavel (referee) ; Rubinová, Olga (advisor)
The bachelor thesis designed ventilation for the pool hall. Hall is divided on four separate working units. The first device is designed as an air-conditioning unit for the changing room. For swimming pool were designed swimming pool air conditioning units with heat pump. Air in the hall with a water slide is adjusted using the forced ventilation unit.
