Heating and preparing of domestic hot water via solar system
Lustigová, Andrea ; Adam, Pavel (referee) ; Horák, Petr (advisor)
The aim this bachelor thesis is the design of heating and preparing of domestic hot water via solar system. The theoretical part deals with the solar systems, solar collectors and stagnation of solar systems. The second part deals with a separate proposal heating and preparing of domestic hot water in a family house. As a heat source was proposed condensing boiler and solar collectors. The hot water is also ensured condesing boiler and solar collectors. The third part consist of a technical report and drawings heating of the specified object.

Heating of the School Building
Holková, Soňa ; Wierzbická, Helena (referee) ; Vendlová, Lucie (advisor)
The subject of this bachelor's dissertation is heating of the Primary and the Kindergarten school's buildings. The main aim is to make a design of the heating system and the hot water preparation. The source of the heat is the hot-water pipe, which the buildings are connected trough the heating coil to.

Pressure losses in heating systems
Švanda, Martin ; Horká, Lucie (referee) ; Počinková, Marcela (advisor)
This diploma thesis deals with pressure losses in heating systems. The diploma thesis is divided into three sections. The first part is theoretical and deals with the occurrence of pressure losses. It discusses the properties of the fluid that affect pressure losses. It also deals with hydrodynamic phenomena, flow distribution, pressure loss distribution and its calculations. The aim of the second part, which is practical, was to create a heating project for a selected object. The object is a two-floor kindergarten building located in Velké Němčice. For this project, two heating variants were created. For the first variant, radiators and heating benches were designed and for the second variant, underfloor heating was installed in the building. The goal was to use a source which will gain heat mainly from renewable sources, so the air / water heat pump was chosen as the source of heat production. The project ends with a technical report. The third part of the thesis is dedicated to an experiment which purpose was to find out how the pressure losses of the connecting pieces are reacting to the change with the change of the heating water conditions (flow, temperature). Alongside, two pipes were created which differed in the type of connecting pieces so it allowed to compare how their pressure losses differ. Both pipes were connected by radial pressing, but the fittings differed in the quality of the brass, and therefore in the construction. Also, part of the experimental section of the diploma thesis is a description of the course of radial pressing of fittings from the Herz company.

Proposal heating system of the house
Taclík, Jakub ; Štelcl, Otakar (referee) ; Baláš, Marek (advisor)
This thesis is focused on computation of family house heat losses with two floors above ground, choice of three heat sources, and designing of radiators to cover the losses. The thesis also contains computation of a fuel consumption for a heating period and a discussion which one of heat sources, with particular temperature gradient, is the most economic.

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.

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 efficiency of heat distribution
Vích, Pavel ; Horák, Petr (referee) ; Počinková, Marcela (advisor)
This diploma thesis focuses on the analysis of heat loss of heating distribution in the industrial area. The aim of this labor is to determine heat loss heat distribution kept in non manholed canal and evaluate economic return to build a local source of heat for the office building. For this building is in two variants resolve the reconstruction of the existing heating system. For the first variant is designed the local gas condensing boiler and for second variant existing central heat source. The experimental part of this labor compares the measured and calculated values of boundary conditions of hot-water pipes kept in non manholed canal.

The use of renewable for multi-purpose building
Němec, Filip ; Horák, Petr (referee) ; Formánek, Marian (advisor)
The goal of my final thesis is to get to know the problematic of renewable energy sources and it’s use. I have divided my thesis into three parts. First part is theoretical and it is about renewable heat sources. It goes deeper into use the energy of sun and heat pumps. Second part is proposal of heating system and the preparation of hot water. It includes the calculation of heat transfer coefficient, thermal losses of individual rooms and the proposal radiators and all the sub-elements. Within the study of possible options for renewable sources, it suggests three variants of the heat source and then the chosen one for further processing. The last, third part contains technical report and construction documentation.

Proposal heating system of the house
Minařík, Petr ; Hrnčířová, Michaela (referee) ; Baláš, Marek (advisor)
This work includes the calculation of heat loss and design of the house heating system. To determine the heat loss of the family home will be used standard ČSN EN 12831. Heat loss will be calculated for each room. Radiators are designed to individual rooms for different temperature gradients and by heat losses. The lounge is designed underfloor heating. For heating are designed three different heat sources. One source of high-temperature and low-temperature two sources. The investment costs of the heating system will be evaluated finally.

Heating of the guesthouse
Kubík, Michael ; Vendlová, Lucie (referee) ; Počinková, Marcela (advisor)
The main subject of this bachelor thesis is the design of a heating system for a guesthouse located in a mountain area. The thesis is divided into 3 main parts - theoretical, computational and project. In the theoretical part, biomass and also petels are introduced. The second main part is focused on the concrete design of the heating system for heating and hot water. In the last part of the thesis, the technical report and the design of the building are provided.
