Design of ventilation system in family house
Hrbáček, Jiří ; Toma, Róbert (referee) ; Pech, Ondřej (advisor)
The aim of this bachelor thesis is to design a ventilation system with recuperation in a family house. In the first chapter the work focuses on the research of ventilation units and their parts. Furthermore, the required amount of ventilation air is determined, and three ventilation units are selected. The duct route is then designed for the selected units and the pressure loss calculation is performed. In the final part the installation, operation and maintenance costs of the selected units are compared.

Local Control of Seat Ventilation and Its Impact on Human Thermal Comfort
Matuška, Jaroslav ; Toma, Róbert (referee) ; Fišer, Jan (advisor)
Diplomová práce je zaměřena na měření ventilovaného sedadla s ohledem na tepelný komfort člověka. Popisuje a shrnuje tepelný přenos lidského těla s okolím a termoregulaci člověka. Dále zachycuje a zhodnocuje vybrané přístupy hodnocení tepelného komfortu. Zabývá se komplexním přehledem tepelně komfortních jednotek v automobilu. Představuje použitou metodu měření tepelného komfortu u ventilovaného sedadla, načež analyzuje a vyhodnocuje jednotlivá získaná data.

Measurement of clothing sets by means of thermal manikin
Hanzlík, Martin ; Toma, Róbert (referee) ; Fišer, Jan (advisor)
This diploma thesis is focused on the experimental determination of thermal resistance of the gloves and their combination in the layering system. The measurement was based on procedure specified in the standard ČSN EN 511 by means of thermal manikin. The thesis begins with the description of heat transfer mechanisms, description of glove materials and measurement methodology. The body of paper consists of the measured data analysis and equation design for determination of the glove layering system thermal resistance. At the end of the thesis, these equations are evaluated and it has been shown, that the thermal resistance of glove layering system cannot be precisely determined by the calculation, and it is necessary to measure the whole three-layer system.

Air-conditioning of office rooms
Taclík, Jakub ; Toma, Róbert (referee) ; Fišer, Jan (advisor)
The aim of this diploma thesis is to design the air conditioning system for one floor of the offices. The thesis is divided into theoretical, computational and design part. The computational part consists in determining the amount of ventilation air, calculation of heat losses, heat gains and psychrometric calculations for summer and winter season. Based on the calculated values, air ducts, end-points and air-conditioning units are designed. The diploma thesis is supplemented with a list of materials and drawing documentation.

Measurement of Cabin Environment by Means of Thermal Manikin and Test Subjects
Toma, Róbert ; Tuhovčák, Ján (referee) ; Fišer, Jan (advisor)
In this thesis, there is processed design of test procedure for innovative HVAC system. This design was created in consecutive phases with use of thermal manikin Newton and climate chamber. Correlation between data from thermal manikin and tests subjects and possible design changes were evaluated after each phase. There are mentioned basics of human thermoregulation, factors which affect thermal comfort and ways in which is possible to measure and rate it with use of thermal comfort scales and comfort zones diagram. The thesis includes survey for testing thermal comfort and scales which are used to complete it. In the end, we mentioned some results alongside with our approach in evaluation of correlation between thermal manikin and test. There is also final design of test procedure for innovative HVAC system which would be used for its calibration and final functionality testing.

Database of typical clothing for cabin of cars
Toma, Róbert ; Pokorný, Jan (referee) ; Fišer, Jan (advisor)
In this bachelor thesis, there are processed databases of typical clothing for cabin of cars. Data are based on information from survey for both women and men for three seasons – summer, transitional season and winter. There are mentioned factors which affect thermal comfort and thermoregulation of human body. The thesis includes options how to measure thermal comfort and how we can evaluate results on different scales. Next, I process the way how we measure thermal resistance of each databases of clothing. Measurements are placed in climate chamber in VUT Brno and we are using manikin Newton made by Measurement technology Northwest. In the end, we mention some results and comparison of both genders.
