Dostavba občanské vybavenosti obce Zdenice. / Finishing of a building civic amenities in village Zdenice

ROSA, Jan January 2008 (has links)
My dissertaion is about projection of new fotball crew cabs in a village called Zdenice. My project has two versions. First version is about projection of new fotball crew cabs including the bar. Second version is the same but without the bar.

Doplňkový větrací systém kabiny vozu poháněný fotovoltaickým panelem / Car Cabin Aditional Ventilation System Powered by Photovoltaic Panel

Zdvořilý, Vítek January 2016 (has links)
The aim of the Master thesis is to design and verify the function of the system for the ventilation of parked car in the summer season with the intention to cut down the temperature peak in the cabin of the vehicle. The design of the system consists of the suitable placement of the fans and corresponding inlets and outlets for the flowing of the ventilating air. The fans are powered by a photovoltaic panel. The functionality of the system is verified by the measuring of the temperature drop in the cabin of the car. The ambient conditions for the setting of the intensity of solar radiation and of the ambient temperature have been chosen from the real measurements from TUBO station which is meteorological station of the Faculty of Civil Engineering of BUT Brno.

Návrh nákladního výtahu / Project of service lift

Kryška, Martin January 2017 (has links)
The aim of the diploma thesis was the conceptual design of a service lift driven by the rigid chain. The introduction part focuses on a general description of lifts and existing issues. The following chapters contain the created lift design, construction of important design elements and functional calculations. In the conclusion, evaluation compared with hydraulic lifts and evaluation of speed of the lift, starting and braking to exact stop are performed.

Odpružení kabiny traktoru / Suspension of tractorcabin

Prokop, Aleš January 2010 (has links)
This Master's thesis deals with construction design suspension of tractor's cabin. At the very beginning there is an overview of different possibilities suspension from others producers. Afterwards there is my constructional working from selection variant of suspension to final project with all details. The another part of my thesis is strain-stress analysis of significant parts of construction and suggestion of comparing the method with the previous variant of suspension.

Svázání fyziologického modelu s modelem tepelného komfortu / Coupling of the Models of Human Physiology and Thermal Comfort

Pokorný, Jan January 2012 (has links)
The thesis deals with car cabin environment and thermal comfort inside. A car cabin heat load model was developed in Dymola/Modelica to investigate influence of ambient environmental parameters. The model was validated on the data set of eight test cases measured in a climatic chamber and in a real traffic. The main objective of the thesis was to develop a human thermal comfort model suitable for non-homogenous environments and for a car cabin environment especially. The Coupled model of human physiology and thermal comfort was developed in Dymola/Modelica. The model allows predicting an overall human thermal comfort from local boundary conditions representing ambient and personal factors. The model was validated by 16 test cases taken from experiments in literature. Moreover three test cases were created in Theseus-FE to consider an asymmetrical heat load from Sun rays inside a car cabin. Prediction of the Coupled model was compared with Fiala model and experimental data. The Coupled model predicted mean skin temperature for moderate activities in neutral and warm environment well. In cold environment a predicted core temperature was very affected by ambient temperature and during high activity exercises, the predicted mean skin temperature was too high.

Optimalizace mikroklimatu v kabinách malých dopravních letadel / Optimization of Cabin Environment in Small Transport Aircraft

Fišer, Jan January 2011 (has links)
The thesis deals with design and optimization of environment in cabins of small transport aircrafts, especially in terms of thermal comfort and quality of ventilation. The design of air distribution systems and structural design were optimized and most important parts of cabin design with highest impact on the quality of thermal comfort and ventilation were identified based on literature research and experience of the author. The chosen modifications and their influence on the microclimate inside the cabin were investigated using the CFD model, which was validated by results obtained from measurements of flow and temperature fields in the cabin mock-up of small transport aircraft EV-55. Next optimizations were investigated: The type of air distribution system, The geometry of ducts of air distribution system, Thickness of thermal insulation and Emissivity of internal surfaces. Thermal comfort was assessed based on the methodology of the equivalent temperature and comfort zones diagram developed by H. O. Nilsson and for assessing the quality of ventilation the concept of based on index of the age of the air was used. Fifty cases were simulated in total and base of its results Modified mixing ventilation with original air ducts geometry have been evaluated as an optimum. The ducts geometry of Modified mixing ventilation system was suggested by author specially for the thesis. In combination with high thermal insulation of walls and high emissivity of the interior, then this system of ventilation ensures maximum thermal comfort and quality of ventilation for the investigated range of environmental and operational conditions.
