Pipe materials
Pecl, Tomáš ; Helcelet, Marek (referee) ; Molliková, Eva (advisor)
Objective of the bachelor thesis is to introduce the important aspects of the material for the manufacture, installation and operation of pipeline systems. The thesis mentions the suitability of individual groups of pipe materials for various technological and natural conditions with respect to the material properties. The work deals with the pipe installation, implementation of control tests with a focus on of technology pipe installation before commissioning, finding defects and the possibility of repair. Finally, in the work are placed practical information that helping solve problems

Heating of the Residential Building
Molnár, Lukáš ; Topič, Jan (referee) ; Vendlová, Lucie (advisor)
The goal of the work is to design heating and hot water production in an apartment block. Condensing gas boilers were designed for a heating system and a hot water storage tank, boilers should be located in a technical room in basement. Plate and tubular heating units are the heating surfaces. Heat consumption measurements in flats are gauged by remotely monitored calorimeters. The temperature in each flat is controlled by an electrically powered zone valve.

Heating of the Kindergarten
Náglová, Michaela ; Topič, Jan (referee) ; Vendlová, Lucie (advisor)
This thesis deals with a theoretic description of underfloor heating system, its parameters and describes a design of ventilation used in school buildings. The aim of its practical part is a design of a heating system for kindergarten building, a system of hot water distribution, heat sources and forced ventilation for chosen rooms. The heating system combines radiators and underfloor heating. Calculations are based on thermal performance of each room.

Condensing boiler and solar collectors in a residential building
Bukovjan, Jiří ; Vendlová, Lucie (referee) ; Horák, Petr (advisor)
The subject of this thesis is the heating and hot water preparation in the residential house in Rožnov pod Radhoštěm. Object has four floors and basement. In each floor there are two residential units. In thebasement there is a utility room with heating, gas boiler cascade. Used to heat-pipe heatingsystem. Heating surfaces are plate and tubular body. The primary source of hot water is gasboiler. As a secondary source of alternative preparation with solar system.

Boiler-room apartment house
Lampa, Jan ; Vrána, Jakub (referee) ; Vališ, Ivan (advisor)
The introduction of the theoretical part of the thesis deals with condensing boilers. There is a description of the parts of boilers, gas combustion methods, the amount of combustion air and the overall running of condensing gas boilers. Other parts of the paper describe radiators, thermostatic valves, safety relief systems, piping and circulating pumps. The design section provides an illustrative example of the design of the heating system for a residential building with 12 apartments.

The Effect of Overloading of Pipes on their Fracture Toughness in Relation to the Strength Grade of Steel
Šperl, Martin ; Gajdoš, Lubomír
The present experimental results showed a very positive effect of a controlled overloading of a pipeline on its fracture toughness. These results have been referred to steels of the class L360MB and L415MB. However, more recent results obtained on L450MB steel indicated that the positive effect of oveloading is reduced as the strength properties of steels are increased. It follows from this that the final technological operation of overloading of pipes made from steels of an increased strength could be let out from the pipe manufacture scheme. The paper presents experimental results which prove by evidence a decreasing positive effect of overloading on the fracture toughness of steels of high strength properties.
