Climate testing room for personal vehicles
Málek, Ludvík ; Katolický, Jaroslav (referee) ; Štětina, Josef (advisor)
The diploma thesis deals with the design of testing equipment, a climate chamber in particular, to simulate external weather conditions. The chamber walls are made of socalled sandwich insulation panels. Based on the wall thermal properties, heat loss of the chamber was calculated. The conditioned air is supplied by a distribution channel at sides of the chamber. The exhaust air leaves the chamber in the ceiling zone. The ventilation unit is located on the ceiling. The design includes the integration of the UV lamp, simulating sunlight. The chamber will allow the weather effects on the microclimate inside a car to be studied. Furthermore, the sunlight simulations can be carried out in the chamber to detect polymers or varnish aging, and the fading of colours.

Measuring and regulation of computer controlled solar systems: Vizualization of energetic systems
Vlčnovská Kotlíková, Silvie ; Mašek, Ivan (referee) ; Půčková, Helena (advisor)
This work is oriented on study and evaluation of performance of real operating solar system. There was made analysis of actual technological unit and there was suggested mode of measuring of nodal parameters. There was made interconnection between the head operating unit of the solar system and the web server. And there was prepared software for grafical image of time and temperature dependence and for data transfer to ready web application. It primarily talks about increase of efficiency of real technological unit through regulating of parameter that is using up of accumulated energy.

Analysis of the thermal resistance of insulation systems from foamed insulants in flat roofs
Rundt, Lukáš ; Žák,, Antonín (referee) ; Žižková, Nikol (advisor)
On many structures there ocurred a problem of expanded polystyrene-based thermal insulation material degradation caused by high temperatures close to glazed areas. In a theoretical part of this Master’s Thesis there are the most common thermal insulation materials described, followed by a brief desciption of flat roof waterproofing materials and a thermal stress of structures. An experimental part describes a design of a methodology for evaluation of thermal resistance properties of foamed insulants in flat roofs and several experiments carried out according to the methodology.

Analysis of humid air transport in the building envelope
Tománek, Jan ; Kupsa, Tomáš (referee) ; Žák, Antonín (advisor)
The diploma thesis deals with the analysis of temperature and humidity in the construction of flat roofs with influence even without influence of solar radiation. It was necessary to study and verify the properties of building materials, the physical nature of the influence of solar radiation on building structures and the transport mechanisms of moisture. The theoretical part describes the basic physical theory on solved problems, the essence and division of solar radiation, the description of thermal moisture properties of building materials and the calculation method of determination of moisture in structures according to valid standards. Practical part deals with description of work in software DEKSOFT - Thermal technology 1D and WUFI 2D software, description of individual models and analysis of achieved results. At the end of the practical part the achieved theoretical knowledge is validated by analyzing the obtained data from the practical model.
