AIR-CONDITIONING OF STORAGE AND ADMINISTRATIVE SPACES
Buchta, Jan ; Formánek, Marian (referee) ; Šikula, Ondřej (advisor)
The bachelor thesis deals with air-conditioning and system of chilling for two-floor ad-ministrative and storage part of storage hall. The goal is to design air-conditioning sys-tems and to ensure optimal indoor microclimate. The theoretical part compares three systems of combinated air-conditioning. The result is the choice of optimal combinated systems for administrative zone of solved part of building.solved part of building.

Influence of polymers to reduce dust
Šubrt, Michal ; Mravcová, Ludmila (referee) ; Vávrová, Milada (advisor)
The main issue this bachelor thesis deals with the reduction of emit into the enviroment. A specific type of polymer compound from Canadian provenance will be tested for this purpose. The aim of this work will be the identification of positive characteristics of the polymer, and determine to the appropriate method of application. The above mentioned reduction of dust, stabilization of areas after application, possibly reduction of its permeability and increase of its maximum dry density will also by measured.

Use of the Energy Harvesting Method
Dobrovolná, Terezie ; Králík, Martin (referee) ; Sekora, Jiří (advisor)
The bachelor thesis deals with the use of Energy Harvesting. It contains suggestions for obtaining electric power from alternative sources located inside the laminar box such as light, heat or vibration. Electricity is also used to power sensors and measure solid particles in the air. If a certain particle concentration is exceeded, the acoustic sensor alerts. The work also focuses on the compilation of a block diagram of the device, experimental construction and verification of the functionality of the entire system.

Accumulation of electricity from renewable sources
Plíšek, Petr ; Špiláček, Michal (referee) ; Pospíšil, Jiří (advisor)
This diploma thesis deals with the issue of accumulation of electricity produced by renewable sources. The first part focuses on the description of possible ways of accumulation, especially with focus on those methods, that are suitable for renewable energy sources. The next part deals with the design of the accumulation energy in the compressed air for the selected photovoltaic power plant. The necessity of designing a particular method of energy storage, is also its technical and economic analysis, which is the content of the last part of the thesis.

Flow measurement of air by multiport averaging probes
Šimák, Jakub ; Uher, Miroslav (referee) ; Šedivá, Soňa (advisor)
Master work deals with the measurement of fluid flow (particularly air) pipe, with orifice and multiport averaging probe. The theoretical part is followed by practical, which verifies the properties of the measured system. In a next part of semestral work are verifies the properties of multiport averaging probes Vavra s.r.o. MQS-011 and Rosemount Annubar 485. Measured values from probes are compared.

Assesment of air concentration in water depending on pressure
Uttendorfský, Petr ; Himr, Daniel (referee) ; Pochylý, František (advisor)
This bachelor thesis deals with air concentration in the water. The general conception comes from Henry's law about gas dissolved in the liquids depending on pressure. The basic derivation, the values which influence dissolvability and the Henry's Law constant´s forms are discussed here. Next part is about the usage aeration in the industry and in the construction of aeration systems. The special equipment is for realization experiment. This special equipment is gas´s accumulator based. The measured values are expressed as the tables and the graphs. The data from experiment validated the force of Henry´s Law: with growing pressure above water level, the air concentration in the water is growing too.

Project and calculation of heat exchanger
Kóša, Štefan ; Lisý, Martin (referee) ; Skála, Zdeněk (advisor)
This master’s thesis is concerned with design of a heat exchanger for a unit with gas turbine. The pressurized air from the compressor is heated with flue gases from gasification and subsequent combustion of wooden biomass. Then it is led to the expansion turbine. For thermal and hydraulic calculations a program named HTRI Xchanger Suite® has been used. The thesis includes a brief description of heat exchangers, description of the used program, calculation and selection of input data, solving and conclusions. It contains also a layout of the exchanger.

Study of surface tension of systems applied in ultrasonography.
Říkovská, Klára ; Pekař, Miloslav (referee) ; Mravec, Filip (advisor)
Surface tension of sonography systems was investigated using several experiments. These experiments were comprised of measurements of surface tension using BPA-800P tensiometer. The influence of surface tension of commercial substance SonoVue®, which contains in its structure two types of phospholipids, was studied more detailed. Other phospholipids were studied to comparison with SonoVue®. All substances were dissolved in saline (0,15 M NaCl). Effect of gas type on microbubbles formation and surface tension was investigated. Some samples were studied using du Nüy ring method. It was found that gas constructing the microbubbles (air or SF6) has no impact to the surface tension value. Production of foam on the surface of solutions has an impact on the value of the surface tension. This foam degreases the surface tension. Gas pressure is significant to comparison of measured data.
