Control and regulation of the temperature of the drug transport box
Maťašová, Daniela ; Králík, Martin (referee) ; Sekora, Jiří (advisor)
This bachelor thesis deals with the solution of drug transport in a transport box over longer distances. The work also deals with sensors for temperature measurement and methods of its control and regulation. The essence is the design, implementation and verification of the functionality of the transport device, which allows the display of continuous information about the state of the temperature inside the transport box. Temperature control is powered from the car’s on-board network and temperature sensing is powered independently. The transport device allows the setting of the limit temperature up to 35 °C, while exceeding it is indicated by an acoustic and visual alarm. The transport box, which is the result of the work, allows the transport of drugs, and ultimately meets all the requirements of the assignment.

Cooling of a powerful light source
Tulis, Vojtěch ; Tuhovčák, Ján (referee) ; Hejčík, Jiří (advisor)
The diploma thesis is focused on calculating the thermal resistance of the line light source and the design of the cooling system with ideal inlet temperature. The partial aim of the work is in cooperation with CAMEA spol. s r. o. to determine the thermal resistances of the individual parts of the device and propose modifications so that the total thermal resistance and the maximum temperature are within the limits given by the cooperating firm. The main objective is to design a cooling system with all safety features and recommended regulation for economical and reliable operation. Analytical calculations, CFD simulations and real-world testing are used to determine the desired results. A reduction by 30% in thermal resistance of the printed circuit board was achieved, the thermal resistance of the aluminum profile with the cooling channel was determined and its hydraulic properties were calculated. The current cooling system designed by CAMEA spol. s r. o. for less powerful diodes was verified for use in a more powerful system, and a new cooling system was designed for efficient and economical operation in a powerful diode system.

Revitalization of a multi-purpose building in the village
Federla, Jakub ; Nováková, Eva (referee) ; Kolář, Radim (advisor)
The aim of master‘s thesis is to renovate old agricultural building and design it as nzeb building. The thesis contains three parts: 1st – design of the building, 2nd – design of building services, and 3rd – assessment of the impact of different operations in building on energy consumption. The results are then evaluated for economic and environmental savings. The renovated building in village Rozkoš will be used for many purposes. It will be divided into 3 parts – a multifunctional hall, a pub, and a club room. Multifunctional hall will be used for various activities for village itself or public. In the pub will be only cold kitchen with small dishes and beverages. Club room can be used for elderly people, workout or young people. The building is low rise and structural system is combined. The vertical load-bearing walls and columns are built of bricks. Horizontal load-bearing structures are cross vaults made also of bricks. Saddle roof is made of timber roof truss. The building site contains also an outdoor car park and a garden. The project was carried out in the Revit.

Civic amenities building
Brázdová, Kateřina ; Pilný, Ondřej (referee) ; Berková, Petra (advisor)
Mixed-use building in Prostějov The aim of this master´s thesis is to elaborate the project documentation of a mixed-use building in Prostějov. The thesis consists of three parts: architectural-construction part, building services and elective part. The building has two above-ground floors. On the first floor there are storerooms, utility room, sanitary facilities and restaurant with kitchen and storerooms. The second floor is an office floor for one company which includes offices, dayroom, copyroom, meeting room and sanitary facilities. The building is founded on reinforced concrete foundation. The horizontal load-bearing and non-load-bearing structures are designed from ceramics blocks. The building is insulated by ETICS. The vertical load-bearing structures are designed from Spiroll slabs. The building has a green flat roof. There are parking spaces on the grounds. The building will be heated and cooled with a heat pump. It will also have an air condition. Part of electricity demand is covered by photovoltaics. In the third part of thesis, I replace frequently used materials with environmental ones in my project and compare them in terms of thermal engineering, acoustics and price. I used DEKSOFT, Hluk+, Autocad and Revit software. All structures comply with the valid standards and regulations.

Airplane Cooling System Optimization
Lajza, Ondřej ; Fiľakovský, Karol (referee) ; Horák, Aleš (referee) ; Píštěk, Antonín (advisor)
Dissertation thesis is focused on the aircraft cooling system optimization. The knowledge of the pressure loss is necessity for design of an optimal system. In the beginning of the thesis, the different designs of piston engine cooling systems are described for both aircrafts and automobiles. Other sections outline the determination of the coolers characteristics and describe the different test sections applicable for the characteristics measurement. The test section built at the Institute of the aerospace engineering is described as well. Practical part of the thesis describes the calibration of the test section. The measurements of the specific coolers were compared with the CFD simulation of two models - the simplified cooler model and cooler element model. Additionally, the measurements were compared with results obtained at specialized coolers testing facility.
