Tepelná vodivost u nestandardních materiálů pro TZB / The thermal conductivity of non-standard materials for HVAC

Běťák, Karel January 2019 (has links)
The thesis is focused on the determination of the thermal conductivity coefficient on the group of thermoplastics used for 3D printing (PLA, ABS, PETG). The thesis describes the materials used for 3D printing and the design of air conditioning for the grocery store. A stationary method was used for the solution. The heat flux passing through the sample was measured and the thermal conductivity coefficient was calculated. By the chosen method, we determined the coefficient is = 0,11-0,13 W/(m·K). Comparison with the available results of other methods and authors has shown that the resulting coefficient is lower. Based on the data, it is possible to compare the thermal properties of 3D printing materials.

Filtrace vzduchu / Air filtration

Krajčová, Kateřina January 2019 (has links)
The diploma thesis describes the design of air conditioning equipment of materni-ty hospital and experimental measurement nanofilters and their subsequent comparison with conventional air filters. The work consists of three parts. The first part describes the types of filters. Nanofilters and nanofiber materials are de-scribed in detail here. In the second part is the topic of air filtration applied to the maternity hospital. Two variants of air conditioning and cooling are designed for the 3rd floor of this building. The third experimental part deals with antibacterial effects of thr silver fiber nanofilter and its comparison with commonly used filters. It also deals with the pressure drop on the filters at different air speeds.

Návrh větrání a chlazení v rodinném domě / Design of ventilation and cooling system in family house

Bareš, Josef January 2020 (has links)
The diploma thesis is focused on a ventilation and cooling design of a family house. Author’s idea was to make summary of theoretical information and project documentation for realization (installation) of the ventilation and cooling. Introduction of the house disposition, theoretical research of a current cooling and ventilation options in residential buildings are parts of this thesis. Next it contains thermal load calculation, two designs of a cooling and three designs of a forced ventilation, dimensioning of the pipelines and financial cost comparison of a purchase, assembly, working and service of a designed systems.

Energeticky úsporný administrativní objekt s posilovnou a wellness Kostka / Energy efficient office building with gym and wellness Kostka

Kotas, Marek Unknown Date (has links)
The master thesis describes a complete design of an office building, including its technical equipment. The building's technical equipment contains HVAC, lighting, DHW and photovoltaics design, water demand. The building has two floors. It contains offices, a bistro with a lounge, a wellness area and two gyms, a children's playground and facilities. This master thesis is divided into three parts. Firstly, the thesis presents building documentation with an engineering and an accompanying report. Secondly, the thesis introduces the design of the building's technical equipment and engineering reports. Lastly, the results of a conducted experiment are presented. In this experiment, a system for the optimization of blind tilt angle is proposed.

Tepelná čerpadla ve vzduchotechnice / Heat pumps used in airconditioning

Géryk, Ondřej January 2012 (has links)
This thesis deals with issues of heat pumps for air conditioning purposes. Mainly addresses itself with physical principles of heat pumps and with division of heat pumps according to natural resources, from which they draw heat energy. The next part of this thesis dedicates itself to experimental measurement of air conditioning unit, which in winter time operates on the principle of heat pump. The last part of this thesis is focused on design of two options of employment of heat pumps as sources of heat and coldness for a central air handling unit, which regulates incoming air for a dining room in a retirement home in Brno.

Teorie vnitřního prostředí / The theory of internal environment

Blažková, Klára January 2013 (has links)
The aim of master's thesis is to find an optimal solution in terms of window shielding factors in shaping the internal environment in the interior. In therms of this work there was used a computer program Teruna to created mathematical model entered the room in the experimental section. The theoretical part inquires into the theory of the internal environment. The project inquires into the design and application of a mathematical model of two variants room office in the premises of the factory building.
