Laboratory device with temperature control
Telecký, Jakub ; Škrabánek, Pavel (referee) ; Němec, Zdeněk (advisor)
This work deals with regulation and procedures that can be used for this. The theoretical part therefore presents the basic concepts of automation and controllers. The main part is the practical part. The purchased system consists of a regulated system, which must be set up correctly. Using system identification and known procedures, sample examples of how to best set the controller are compiled. The result is a sample laboratory task that automation students can try and gain experience with methods of setting up the controller.

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.

Design of Cooling and ventilation system in family house
Bíza, Michal ; Charvát, Pavel (referee) ; Pech, Ondřej (advisor)
The diploma thesis is focused on the design of ventilation and cooling for the family house. The first part of the thesis deals with possibilities of ventilation and cooling, air ducts and their components and selected ventilation units. The next part deals with the analysis of air-conditioning routes, their dimensions and pressure losses. Then the heat gain is determined, and cooling is proposed. The last part deals with the comparison of financial costs for purchase of all components for ventilation and cooling, assembly, installation and operating costs. The enclosed drawings and item lists are at the end of the thesis.

Design of beer tap
Vaňková, Klára ; Sládek, Josef (referee) ; Ondra, Martin (advisor)
The subject of my bachelor thesis is the design of a beer tap, in particular portable beer cooler and dispenser with a built in air compressor which has to comply with demanding constructional, ergonomic and aesthetic requirements. The ultimate goal of the designing process is to facilitate the portability of the dispenser and enhance its looks by creating a new visual style relating to the Czech tradition.

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.

Airconditioning in a sport center
Šafář, Robert ; Tesař, Zdeněk (referee) ; Rubina, Aleš (advisor)
Bachelor work is focused on designing an air conditioning system for the gym so as to meet functional, hygienic and operational requirements for the microclimate of sports building. The main tasks of the device are covering heat losses of area of the gym in the winter and transportation of fresh air into the room. The system is also designed to cover the summer heat gains. The first theoretical part deals methods of heat recovery for air conditioning needs, and the second part contains two designs of ventilation of changing rooms and air conditioning system for gyms. The result of this work is detailed design work for two air conditioning equipments for specified object.

Utilization of absorption systems in the heating systems
Vidlák, David ; Špiláček, Michal (referee) ; Pospíšil, Jiří (advisor)
Main goal of this work is familiarization with basic features of absorption heat pumps and it’s growing importance on the market. In the first part of the work there is a research for clarifying facts associated with such pumps. In the introduction there are descriptions of basic information from the field of heating industry and its connections to our systems. Next there is a brief analysis of price changes in electricity and heat in the last five years. Main part of the analytical section is a description of the used absorption system. Second part of the work is focused on the calculation of the absorption system itself. First there is calculated internal and external part of the device according to the parameters from GE Power s.r.o. After this step there are parametric studies based on changes of key parameters of the default device for a demonstration of the behavior of a heating pump. In the end of the work there is a integration of the unit into the heating cycle for variations including flue gas condenser and using a cooling water from the turbine condenser.

Calculation of thermal resistance of finned heatsink
Kyanka, Radim ; Huták, Petr (referee) ; Toman, Marek (advisor)
This bachelor's thesis is focused on the problem with analytical calculations needed to define thermal resistance of finned heat sinks. First it describes how temperature proceeds at different boundary conditions at fin tip. Than it describes different mechanisms of heat transfer, equlation of heat resistance especially of natural and forced convection. To verify the results there is comparison between analytical equlations written in Matlab program and measuring results.
