The diploma thesis deals with overall reduction of energy use in the family house by reducing heat loss and selecting heat and cold source. In the first part are described different types of heat loss along with ways to efectively reduce each loss. Contact insulation systems are further more described, because of beeing used more often. Newer materials are also presented to readers, although their use is less common. The next chapters describe the parameters of choosed heat and cold sources. The calculating part describes process of annual power usage calculation. Further there are three designs of thermal insulation proposed and for each one the appropriate heat and cold source is selected, using heat pump with bivalent operation for all designs. Finally these options are compared in an economic and technical way and the most advantageous of them is determined.

The introductory part of this diploma work contains a basic thought for the application of the heat pumps cascade connection and further I describe its function and define the notion of an optimum middle temperature.Then the direct comparison of two heats pumps cascade connection with an one-stage heat pump is shown there in a concrete example. The main part of the work is aimed to the determination of the most suitable variant for the heating and for the preparation of a hot service water in a benchmark family house. The systems of heatings are provided in options of a low-temperature floor heating and hot-water radiators. Both types of the heat pumps supply the warm to every heating system. It results into four possibles alternatives of the building heating.Besides of the alternatives mentioned above, a new variant of optimalised cascade connection was arisen during this work elaboration . The first stage of this connection which supplies the warm to the floor heating is disconnected out of the heating season and the second stage provides only a hot service water warming. The results of this work showed us that just this variant of a cascade connection causes savings in energy in comparison with an one-stage heat pump. In the conclusion of this work there are discussed the reached results and indicated the possibilities of a practical exploitation.

Low cost, rapid and high thermal by IR heating, rapid cooling and high efficiency, there are RTP (Rapid Thermal Processing) properties. We can use RTP for annealing, diffusion, contacting, oxidation and others. Rapid temperature change and IR heating can be followed positive effects in the silicon substrate. This paper is focused on annealing by RTP. Wafers were p-type monocrystalline CZ silicon with different bulk minority carrier lifetime. Minority carrier lifetime was measured by MW-PCD (Microwave Photoconductance Decay) before and after thermal processing.

The main goal of the submitted thesis is the design of central conditioning system used to ensure the required internal microclimate of office space and meeting rooms on the 2nd floor of office building, located in the city of Brno. The first part provides an overview of air conditioning systems and the appropriate central air conditioning system is selected. In the next part is designed the devices for air conditioning by building layout, properties of building structures, equipment and office space occupied. The work also submits drawing documentation, technical report and specification of materials used.

The aim of this thesis is to design the heating system for the house, including the design and calculating the required quantity of heat for hot water. The specified heat sources are the heat pump air to water and solid fuel boiler. The task was to design the heating system to the fastest possible return on investment. The initial investment in a heat pump is high so it is necessary to design the heating system as efficiently as possible. The thesis contains a complete project of calculating heat loss of the building, the design of heating surfaces and their heat-technical calculation. There is included the design of the pipe system, the calculation of pressure loss and its regulation. The thesis also includes design of safety equipment, temperature regulation and drawings. On the basis of calculated data was processed economic assessment, which determines the return on investment to the heat pump. Compared to the gas condensing boiler the return on investment will ideally be after five years.

Diploma thesis deals with change of heating source for a block of flats with aim to reduce heating costs. Thesis contains calculations of energy requirements of house, including requirements for heating and domestic hot water preparation. Several ways of heating by a heat pump were designed based on the calculated values. Each variant of the designed heating system is compared with current operational costs. Possible cost economies and maximum value of investment costs of the heating system were assessed

The thesis is aimed on a proposal from heating sources, heating systems and ventilation of family house. Designing of a house is provided by Keeo4design. This proposal contains a complex of two houses. The first one is used for residential purposes, the other is made up of mostly parking garages. The work focuses on heat loss calculation objects. Subsequently, on a proposal from heating sources, heating systems, ventilation systems and their regulation.

The task of this diploma thesis is to design a basic unit of a living house - container, which will be suitable by its proportions to be transported easily on the roads and at the same time it will meet the requirements of a thermal protection of a building. Other complementary units are designed to the basic container to extend a house space with new rooms. There have been designed four options, for which the author calculated heat loss coefficients and defined energy ambition grade of building. For the basic unit the calculations are made for two grades of a thermal isolation. For an exact definition of these results, linear thermal bridges were calculated. Methodical process of construction composition assessment and a process of heat loss coefficients calculating are made regarding a standard ČSN 73 0540 Thermal protection of a building. Energy ambition grade of building is defined according to a public notice n.78/2013 about energy ambition grade from 22th March. According to a standard ČSN EN 12 831 there have been planned a heating load for every individual room.

The goal of the diploma thesis was to elaborate applicable solutions for the use of low-potential waste heat from the Nuclear Power Plant Temelín for agricultural production. A greenhouse of the 1 hectare size has been proposed as a model project for tomatoes production. First, in diploma thesis discussed universally questions related with building greenhouse, such is safety issues servis Nuclear Power Plant, the suitability of use different technologies, property law, suitability of the locality construction and impact on the environment... Then was detailed processed version for heating-up greenhouse of the 1 hectare, including solution key problem . Part of this diploma thesis is economic balance and proposal for the future practical use.

Thesis is focused on thermal-insulation properties of wood fibreboards and building structure model including non-ventilated air layer. In the first part, the influence of temperature and moisture content on heat conductivity coefficient and heat transfer coefficient of wood fibreboards was investigated. In the second part, the building structure model was prepared, consisting of CLT, air layer and wood fibreboard. Subsequently, the two above mentioned characteristics were determined in dependence on measuring temperature, air layer thickness and inner surface emissivity.
