Abstract:

The topic of presented master’s thesis was study of passive stabilization of building materials temperature. The main goal of this thesis was measuring and characterization of the thermal properties of building materials, which are used to PCM technology. PCM technology is based on utilization of latent heat of phase change. At the beginning of this thesis it was needed to define physical principle of phase change, then the most usable PCM chemicals (e.g. paraffin, Glauber’s salt, hexahydrate calcium chloride) and their basic physical properties (especially thermo-physical), background research of building materials with PCM and also the methods of thermo-physical properties measurement. It was also needed to characterize measured building materials and define theirs thermal parameters; because the values of thermal parameters of measured samples were compared to these values. In the experimental part of my thesis are measurements of material thermal analysis, which are methods, where the properties of materials are studied as they change with temperature. I had used to differential scanning calorimetry, transient pulse method and other methods, which are usable for thermo-physical properties measuring and characterization. I have been much interested in properties of measured material, which were specific heat capacity, temperature diffusivity, heat conductivity and phase change temperature (the melting point of PCM). At the end of my thesis the findings of all methods were finally summarized, compared and commented.

Abstract:

One of the key issues of our society is to decrease energy demand. About 40 % of energy consumption in Europe is related to building operation, mostly for heating. The required thermal comfort is related mainly to temperature of air and temperature of surrounding surfaces. Especially in older buildings with low level of thermal insulation the inner surface of perimeter wall can be several degrees colder than air. In such case the perception of thermal comfort will be lowered also depending on the layout of the room. Other issue can be related to thermal radiation asymmetry. The amount of energy that is eradiated from a surface is driven by material property called emissivity. A surface with sufficiently low emissivity will became “thermal mirror”. It is possible to elaborate about intelligent thermal management of the internal space with usage of low-emissive surfaces; where thermal radiation can be suppressed or can be enhanced. This depends on the surface emissivity and its real temperature. Recently, growing interest about the low-emissive surfaces can be seen. They can represent reasonable complement to conventional insulation, but they have certain limits. Potentially, even higher energy savings can be reached with so called retro reflection. If the thermal radiation of an object is reflected back, its thermal loss will be lower. In such case it can be expected that equivalent thermal comfort can be reached even with lower overall temperature of the room. The aim of the work is study of material combinations with potential for utilization as low-emissive interior surfaces. Research has been conducted on low-emissive paints and low-emissive foils. Another part of the work is related to retro reflection of thermal radiation as a potential way to influence thermal comfort. The work shows, that energy saving up to 20% can be obtained.

Abstract:

In the present time, when prices of energy go up continually, we can hear more and more about the topic of energy-cutting. Important role in this sphere performs low-energy development. Passive houses, which are specific type of low energy houses, cut heat demand significantly. It means marked improvement with the view of energy saving, protection of the environment, but also quality of living. There is no doubt that these constructions bring numerous advantages, as evidenced by ever-growing number of passive houses abroad. Nevertheless, in the Czech Republic are very little passive houses. Partial intention of the thesis work is to highlight the importance of certification, which is able to contribute toward expansion of passive houses. The outcome of this part is proposal of the criteria for certification of passive houses in the Czech Republic. Principal aim of my diploma work is to compare passive house to common house in light of capital expenditures and operating costs and information about pay-off period of investment in low-energy buildings. Just matter of economic return is the most important criterion in decision making about construction of house or building.

The calculations show that the traditional concept of the timbered structures is inefficient for the mentioned energy standards. The minimal thickness of the timbered wall which will satisfy the requirements of the energy standards for low-energy and passive structure were calculated for the proposed four types of wall composition. For the calculations methods according to the applicable standards ČSN were used. To verify accuracy of these method and the performed calculations simplified numerical model was made in finite element software.

Abstract:

The master thesis deals with passive houses and their profitability's economic analysis. The thesis focuses on both new buildings and renovations, which have the greatest potential for energy savings in the building's sector. The cost-effectiveness of proposed measures is evaluated using the example of reconstruction of an existing house with passive and low-energy standard. Low-energy option of reconstruction is more profitable from an investor's perspective than the passive one. At 4% annual growth in energy prices, both options become comparable. The result of the calculation is not generally applicable. The profitability always depends on a specific building and various measures. Besides the cost-effectiveness, the investor's decision about an investment is also influenced by an increasing level of living comfort, subsidies and environmental protection.

Abstract:

This diploma thesis deals with four chosen types of vertical sheathing of houses in the passive standard and their overall thermo-technical and economic evaluation. At first, the materials which may be used in wood constructions of vertical sheathing of a house are described. Further, a design and thermo-technical assessment of each of the structures is performed. Wooden structures using environmentally friendly insulation are designed for three types of vertical sheathing and the system Ytong with external insulation is proposed for the fourth type, currently often used in the construction of passive houses in the Czech Republic. In order to comprehensively assess the building envelope, the composition of the roof and floor on the ground will be designed. The other part deals with the evaluation of the building envelope, separately for all four vertical sheathing options. An economic comparison of the envelope options based on the creation of itemized budgets will be carried out. Finally, the pros and cons of using each of the proposed envelope compositions will be evaluated.

Abstract:

The main aim of the doctoral thesis was study of passive microrheological techniques as advanced methods for characterisation of viscoelastic properties of soft material. These techniques are able to provide certain advantaged or additional information on classical rheology. Several techniques from the wide range of passive microrheological group such as one particle video – microrhelogy with IDL data procesing, microrheology based on light scattering – DLS or FCS microrheology have been applied in practice during my PhD studies. New Matlab script has been also invented to simply obtain information about viscosity of low volume samples. Aplicability of techniques were studied on several various bicolloids such as solutions or gels of hyaluronic acid, on study of properties at the interfaces or on gelation proces studies of agarose. Obtained data were compared classical rheology results. Suitability of each technique for investigated systems or appropriate reccomendations for further measurements were didcussed based on obtained data. Main advantages and limites of passive microrheology techniques were also described in comparison wih classical rheology method.

Abstract:

This dissertation thesis focuses on the evaluation of modern machine tools, especially tools for finishing operations, with which the effect of the passive force components on the machining process is evaluated. The thesis will examine the analysis of creating chips and circumstances that accompany this process and substantially involve the formation of a new surface. The analysis of the process of the recording of the power load of the MT3 tool takes place in the experimental part of the thesis. MT3 is a reaming head intended for finishing holes at high cutting speeds (100-200 m.min-1) with removal of small cross section AD (0.024 mm2) chips. Particular attention is paid to the newly created profile from the surface after machining and evaluation of changes in geometry and loading of the cutting edge, which is significantly reflected in the establishment and the development of passive forces.
