Heating system of a Low-energy house
Jankola, Mario ; Pech, Ondřej (referee) ; Katolický, Jaroslav (advisor)
This master’s thesis pertains to heating practices of low-energy houses using a heat pump (example 1) and low-temperature condensing boiler (example 2). The first part of the work contains calculations of suggested building’s heat efficiency and of under-floor heating. The second part of the work includes estimates of seasonal heating factors for construction with a heat pump. Based on the comparison: both of these heating systems are recommended; the capacity of the warm water container is established; and safety elements are chosen. Furthermore, a system of regulation for warm water heating is determined, and a curve of equithermal regulation for heating is calculated. Both of the recommended heating possibilities include calculations of costs of supplies and manufacturing, as well as blueprints for construction.

Specifications in the heat calculation of electrothermal devices
Mikmek, Vladislav ; Foral, Štěpán (referee) ; Lázničková, Ilona (advisor)
This bachelor's thesis deals with the heat calculation of a resistance crucible furnace with emphasis on the influence of selected specifications. The whole process of the heat calculation is described. The calculation used in this thesis requires inputs as the kind of material of the batch or it's weight, the dimensions of the crucible and of the heating elements and others. The output of the calculation is the heat necessary to melt the batch, power needed by the crucible, the dimensions of the resistance spiral, permitted surface load of the spiral and the number of supports in the furnace to hold the heating elements. Parts of the canculation where there is possible to choose different methods to acquire needed values are also mentioned. The last chapter shows on a particular example of crucible furnace the influence of selected specifications on quantities dependent on these specifications. In selected parts of the calculation, that can be done by at least two diffent methods, is shown the influence of the choice on the partial result. In the case of a bigger differences of the results is shown even the influence on the subsequent parts of the calculation and final results. The contribution of the thesis is a summarization of the influences of the selected specifications on the results of the heat calculation. It also shows that some selected specifications have minor and other major influence on the calculation.

Low temperature heating with heat pumps
Bros, Miroslav ; Horká, Lucie (referee) ; Počinková, Marcela (advisor)
The master’s thesis deals with design and comparison of two variants of low temperature heating with radiant systems and heat pumps. Building is used for administrative purposes. The theoretical part describes the evaluation of heat pumps. The calculation part deals with the calculation of heat loss of the building, the design of the heating system, the hot water preparation system, the heat source, all necessary supplementary devices, and the calculation of yearly heat and fuel consumption for heating and hot water preparation of the building. Heating system consists of floor heating and ceiling heating. For hot water preparation an indirect fired hot water storage tank is designed. The source of heat is a cascade of two air/water heat pumps. Experimental part is focused on measuring and assessment of pressure loss, heat output and efficiency of radiant ceiling panel.

Heating of flat house
Hánl, Jiří ; Počinková, Marcela (referee) ; Topič, Jan (advisor)
The theme of my bachelor´s thesis is heating proposal and hot water preparation in apartment house. The teoretical part is focud on applicability and constructional solution of fittings. The calculating part consists of heat source proposal, hot water preparation, distribution of heating water and heating elements design. In the building there are proposed two heat sources, the first one for heating water and the second one for hot water preparation. The heating elemets are panel, tubular and floor convectors. The project part consists of technical report and drawing doocumentation.

Heating residential building
Blažek, Tomáš ; Počinková, Marcela (referee) ; Horák, Petr (advisor)
The aim of this bachelor’s thesis are issues of condensing boilers in theoretical part. The computational part solves design of heating and hot water in residential building in Kyjov. The four-floor residential building is situated in slightly bulit-up area. It consists of 9 flats for 24 persons. The heat source for this building is a gas condensing boiler. The heating surface consist of steel panel radiators, tubular heaters and convectors.

Ventilation and Air Conditioning of Civil Buildings
Matějíček, Michal ; Adam, Pavel (referee) ; Hirš, Jiří (advisor)
This bachelor thesis deals with the design of the air conditioning of a swimming pool in Karlova Studánka. Air conditioning ensures forced ventilation and adjusts incoming air to required temperature and humidity inside the pool. The theoretical part deals with literary research on the topic of humid air, evaporation from the water and the thermal load of the object. The experimental part deals with evaluation of the measured humidity and indoor temperature in a bathroom and in a swimming pool.

Topical and Advanced Possibilities of Heating by Thermal Pumps
Božek, Michal ; Brázdil, Marian (referee) ; Lisý, Martin (advisor)
The bachelor's thesis is focused on search of one of the many methods of home heating systems, specifically on heat pumps. The first part describes the structure of heat pumps, the principle of how they work, main types, their two most important parameters and comparison of them to other systems of heating. The second part contains comparison of individual heating systems from economical point of views on a selected model house.

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.
