This diploma thesis deals with thermal qualities of moulding mixtures of foundry mould of various types of sand grains and a computer simulation of the solidification of the cast. The aim of this work is to compare the values of thermal qualities of moulding materials bonded with water glass taken in experimental measurements to the values of thermal qualities of moulding materials connected with organic binding agent contained in simulation software. A sample cast will be moulded in order to evaluate cooling capacities of individual moulding mixtures according the shift of thermal axis. These results will consequently be compared to the results of the simulation.

The aim of this thesis is to design a low temperature heating system which will be operating in multifunctional wooden house. Ground souce heat pump being the pruducer of the energy in this systém, while the underfloor heating.being the consumer. After a short brief on theoretical level of used systems and devices, there comes a practical part of equations, designing and finding of a best solutions for all necessary parts of heating system. All imporant generated data are packed in a lucid charts. Thesis is trying to be somewhat brief but factical, and just a little bit stylish. At the end of the work there are some economical conclusions of used system like annual energy consumption cost, payback periods comparisons to other systems etc.

Thesis describes the procedures for evaluating performance parameters of heat pumps COP, SCOP (coefficient of perfomance, seasonal coefficient of perfomance). It is focused on the most common types of heat pumps in european geographical conditions, heat pumps air-water, water-water, brine-water.

This diploma thesis deals with comparison of possible ways to supply the specific house by thermal energy. In the first part is a brief introduction of the building and determination of heat consumption. Following chapters are devoted to description and sorting of gas boilers, heat pumps, biomass boilers and solar collectors, inclusive the choice of specific source of heat. In the following part is stated economic evaluation of selected heat sources. Final part of the thesis is focused on design of additional exchanger instead of gas boiler.

The goal of the thesis was research in the field of structure and properties of low alloyed steels used in low temperature environment. Work was focused on heat treatment and chemical composition of the steel and their impact to hardness and impact energy values. Chemical composition and heat treatment of steel was proposed on the basis of achieved results.

Heating and cooling along with the indoor air quality is now discussed topic not only in the family houses. Goes hand in hand with reducing the energy consumption of buildings. This fact is edited by various laws or Regulations, no matter we discuss new buildings requirements, or for example energy label on older constructions.

The diploma thesis contains by renovation of the family House on the “nearly zero-energy consumption building”, the proposal is for a variety of energy measures to achieve this status.

This diploma thesis solves design of heating in a residental building. This work is focused on the selection of appropriate one of the two options a heat source, which are cascade heat pumps ground-water and gas condensing boilers. The theoretical part of the diploma thesis deals with introducing to the issue of heat pump systems. The functional principle of the widely most used types and particularized type ground-water. In the practical part calculation and design of heating system with selected heating source that is cascade of gas condensing boilers.

ZELNÍČKOVÁ Marta: Optimizing of heat treatment of casting produced by SEED method. This work deals with designing optimum heat treatment method for casting alloy AlSi7Mg0,3, cast by SEED. Different temperature and times are tested in regimes of heat treatment, mechanical properties are determined with dependence of on the heat treatment method and optimal temperature regime is determined from the detected values.

This thesis deals with automotive headlamps, focusing on layout of temparature field and its influence on thermal stress of used materials, describes their history, kinds and ongoing research. Thesis shortly describes light and its characteristics, heat and heat transfer and means of temperature measurement. Main part of the tesis is dedicated to measuring front headlamp serving as a fog light, concretely measuring temperature field and illuminance depending of ambient temperature. Thesis contains everything from the first preparations, creation of measuring circuit, programming of measuring to processing acquired data. Thesis also compares cooler used for cooling luxmeter sensor, the comparision is between measured values and created simulation.
