Heating of flat house
Zajíček, Václav ; Vendlová, Lucie (referee) ; Topič, Jan (advisor)
The thesis is composed of three parts - theoretical, computational and a project part. The theoretical part deals with heat sharing through conduction, flow and radiation. The computational part is focused on the overall calculation of the heating system to operate smoothly and reliably. Three gas condensing boilers are designed as a source of heat. The heating of the water is solved as a reservoir. It's source of heat is one gas condensation boiler. The project part contains a technical report and the project documentation on the stage of the implementation dossier.

An assessment of returnability of solar collectors installation in low-energy family house
Hrbata, Jiří ; Pešek, Martin (referee) ; Jaroš, Michal (advisor)
Increasing of standard of living, automation and mechanization of production and industrial growth lead into energy need growth. At the same time the energy prices continuously rise and it is still more preferable to use renewable energy, particularly solar radiation. This thesis contains basic information about usefulness of solar radiation, solar collectors and ways of their integration into heating systems. Particularly, it deals with the assessment of returnability of solar collectors instalation in the low energy family house. It contains calculations of necessary heat for heating, hot water heating and energy gains from solar collectors. Returnability assessment is demonstrated on concrete example.

Family house with a business activity
Václavek, Jaroslav ; Manová, Ludmila (referee) ; Maceková, Věra (advisor)
The topic of this bachelor thesis is a family house with business activities. It is a two-storey house with a partial basement, the roof is pitched with a slope of 35 °. As the structure two-way wall HELUZ walls were used. The building is set on a land slightly sloping towards the west. All structures comply with the applicable standards ČSN.

Experimental heat flux declaration through soil or artifikal substrate using HFP01-SC sensor
VÁŇA, Jan
The aim of this thesis is to describe a method of measuring the heat flow through the substratum or soil with self-calibrating heat flux sensor HFP-01SC (Hukseflux, The Netherlands) and to confirm the appropriateness of its use. In addition, this paper should be a manual for applications using this sesnor. Submitted work should be a contribution to disciplines dealing with measurement of heat flow through the substratum or soil.

Impact of Heat Treatment Environment of Microstructure and Transformation Path in NiTi Shape Memory Alloy
Kuběnová, Monika ; Zálešák, Jakub ; Čermák, Jiří ; Barták, Tomáš ; Dlouhý, Antonín
We report results of differential scanning calorimetry (DSC) experiments in which heat flow (T) from and to Ti-50.9at%Ni shape memory samples was recorded during the temperature scan through a B2 B19’ transformation range. Prior to the DSC experiments, the samples were separately annealed in evacuated quartz capsules containing different hydrogen and helium mixtures with an overall filling pressure of 900 mbar. The quartz tubes containing the annealed samples were subsequently quenched into cold water. After quenching, the capsules were opened, martensitic transformations were investigated by DSC and the microstructure of the samples was assessed by transmission electron microscopy (TEM). Annealing in the mixtures with an increasing partial pressure of hydrogen led to a considerable drop in the latent heat associated with the B2 B19’ martensitic transformation. Results obtained using TEM suggest that hydrogen may function as a catalytic substance that accelerates the long range ordering of Ni atoms in early stages of Ni4Ti3-phase precipitation. The selected area diffraction study focused on patterns in <100>B2 and <110>B2 zones and provided evidence for diffuse scattering due to spatial modulations of the lattice constant. These variations in the background electron intensities might be related to a precursor of Ni4Ti3 phase in its early state of formation.
