Modern Application for Household Heating
Šoupal, Filip ; Brázdil, Marian (referee) ; Lisý, Martin (advisor)
This bachelor thesis is focused on the research of basic sources, methods, and possibilities of heating modern family houses. The thesis is divided into three parts, the first one is focused on the advantages and disadvantages of individual heating sources in the use of renewable and non-renewable energy sources. The next section thoroughly describes and compares the methods of heating considering current emission standards. At the end, there is a technical and economic comparison of the variant of the current gas boiler with the variant of the automatic coal boiler and the modern heat pump. The comparison in interpreted on a model house through performed calculations. For better accuracy, the thesis is enhanced with pictures and tables.

Shaft seals and stuffing boxes of pumps
Pluskal, Tomáš ; Dobrovolný, Martin (referee) ; Štefan, David (advisor)
Pumps are an integral part of industry, agriculture, but also everyday life. One of the main elements that affect the proper function and reliability of these machines are shaft seals and gaskets. The first part of this work deals with individual types of shaft seals and gaskets, their design, application, function and used materials. In the second part, a suitable seal for the selected pump is dimensioned.

Design and lay-out of high pressure pumping station.
Václavík, Tomáš ; Franc, Zdeněk (referee) ; Habán, Vladimír (advisor)
The aim of diploma thesis is design and lay-out of high pressure pumping station with plunger pumps for splash of scales from slabs of hot-rolled. Theoretic (introduction) part of this thesis contain description of formation of scales and description of ways how it is possible remove these scales. And this part contains also explication of effect of water jet on solid material. The practical part of diploma thesis is focused on design of pumping station including of dimensioning of machinery. Part of this work is also technical documentation for proposed pumping station and specification of main machines and devices.

Experimental verification of ejector and creation of mathematical model.
Strmiska, Michal ; Štigler, Jaroslav (referee) ; Habán, Vladimír (advisor)
This diploma thesis deals with the area of ejectors. In the intoduction, an ejector is classed as an hydraulic machine. There is also an introduction of the principle and application of this machine there. The next part describes two different ways of calculation and there is a suggestion how to get characteristics, that were achieved by calculation in MS Excel, projected. The purpose of this diploma thesis is to confront this mathematical model with the experiment done in school laboratory at Kaplan department of hydraulic machines. The description of this experiment and the evaluation procedure of measured values is described in the final part of this diploma thesis.

Heating and hot water preparation of recreation center
Hakl, Jaroslav ; Horká, Lucie (referee) ; Počinková, Marcela (advisor)
Content of this bachelor thesis is heating and hot water preparation of recreation centre in the village Ostužná, district Jeseník. Object have 2 above-ground floors. Ground floor is mainly used to meet people in play room or in common room. First floor is situated six accommodation units with private bathroom and toilet. Technical facilities are situated in ground floor and is consists of boiler room and the adjacent fuel storage. For heating is primary used grasifying boiler. Secondary source for hot water preparation is solar systém, that is supplemented by an electric heater in the absence of sunshine. Heating systém is in horizontal double-pipe version with distributor and collector in each floor. The Individual branches on the distributor and collector connected are sections of a single accommodation unit, that can be individually regulated. Radiators are designed as boards in the VK design.

Use of standard centrifugal pump as turbine
Podešva, Adam ; Franc, Zdeněk (referee) ; Habán, Vladimír (advisor)
This work deals with the use of a centrifugal pump in turbine mode and control of the system where this machine is operated. The introduction describes and divides the various types of pumps and discusses the issue of Euler's pump and turbine equations. The flow control options are also described here. Part of the work is a research that examines the advantages and disadvantages of using a centrifugal pump in turbine mode, the possibilities of using this system and real applications in the Czech Republic and in the world. The main part is the design of a mathematical model in Microsoft Excel, which solves the regulation of the piping system with a pump operating in turbine mode, especially out of the optimal operating parameters.

Sanitation installation and gas installations in the hotel
Šumpík, Vojtěch ; Vrána, Jakub (referee) ; Vaščáková, Alena (advisor)
This Diploma Thesis presents a project focused on the installation of utilities consisting of fresh and hot water distribution, gas plumbing, and waste or sewage piping within the building along with their connection to a public network. The building is located in the village of Ratmerice and is intended as a hotel with a restaurant. In addition, the document presents different options for hot water preparation and distribution, along with an assessment of the advantages and disadvantages of the different systems available. A comparative analysis based on various criteria is carried out to determine the optimal solution for the specific characteristics of the building, its intended use, and the availability of public servi-ces in the given location.
