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 Residential Building
Dittrichová, Zuzana ; Wierzbická, Helena (referee) ; Vendlová, Lucie (advisor)
The aim of this bachelor´s thesis is to find a solution of heating system and warm water preparation and subsequent design of heat source for a residential building. The project consists of a calculation of heat losses, a design of radiators, a dimensioning of pipes and a design of heat source for heating and warm water. The heat source is a gas condensing boiler and warm water in a store tank is heated by heating water from boilers. The theoretical part deals with the fixtures and the regulation of heating systems.

Optimization of Heat Transfer Surfaces of Heat Exchangers
Bartuli, Erik ; Dohnal, Mirko (referee) ; Vinogradov, Andrey Vladimirovich (referee) ; Raudenský, Miroslav (advisor)
Disertační práce je zaměřena na kovové a polymerní výměníky tepla. Hlavním předmětem zkoumání je optimalizace teplosměnných ploch za účelem zvýšení účinnosti výměníku tepla. Tyto cíle byly dosaženy experimentálně a numericky pomocí modelování v ANSYS. Na základě dosažených výsledků byla rozpracována technologie křížového navíjení polymerních výměníků z dutých vláken. Experimentální zařízení původně určené pro navíjení tlakových nádrží bylo modifikované pro automatizovanou výrobu polymerních výměníků z dutých vláken, ježto může být použita při jejich masové výrobě. Tato práce se také zabývala výměníky tepla pro klimatizační systémy. Byly zkoumány možnosti využití polymerních výměníků z dutých vláken v těchto systémech. Mimo jiné byla provedena studie vlivu cyklického tepelného zatížení standardního kovového žebrovaného tepelného výměníku.

Design and optimization of a heat source for resort
Valek, Ondřej ; Počinková, Marcela (referee) ; Formánek, Marian (advisor)
This Master’s thesis deals with design of heating source and heating system in the model object. Design is based on three variants of sources and heating systems. The first option is a heating pump air/water, the second option is pellet boiler and the third option is heating pump ground/water. At first heating losses are determined. Then heating systems and related heating sources are designed. The fundamental part of these free options is a design of alternative source for central heat and and hot water and heat storage. The last part is comparison of all variants.

Using thermoelectric generator to increase the efficiency of the radiator
Kříž, Pavel ; Janák, Luděk (referee) ; Vlach, Radek (advisor)
This diploma thesis deals with a design layout of the fan power supply that ensures the increase of the efficiency of the heating unit. For usage in the areas without electric power, the power supply is secured by thermoelectric generator. The system has to function on the basis of autonomous system which turns itself on only when necessary. In the introductory part of the paper there is a recherché of thermoelectric generators for general usage. Next it mentions the basic findings in from the field of DC/DC converters for low power applications. In this part attention is given to MPPT algorithm. Furthermore basic knowledge from the field of heat transmission together with its most used elements is described. Subsequently existing applications that increase the effectiveness of heating are mentioned. Their disadvantage however is that they depend on the external source of power supply. The practical part to a large extent covers the analysis of the suitability of the chosen thermoelectric module. For securing of the heat gradient of the generator there was a model created meeting the figures in the manual and there are several simulations in the MATLAB program. Furthermore several measurements of the thermoelectric module took place in order to secure realistic figures. Subsequently a DC/DC converter was chosen. Finally the testing was made on the real composition. In conclusion there is an overall evaluation including the real usage and the economical aspect of the project. The outcomes of the work enable to avoid common mistakes that are part of many specialized articles. The created system is to be used after the adjustment of the cooling to the required aim. At the same time it becomes very effective.

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.

Heating of the Residential Building with Commercial Spaces
Kašparová, Eva ; Horák, Petr (referee) ; Vendlová, Lucie (advisor)
This thesis aims to introduce the concept of central and water heating in a residential building with some commercial premises in Brno city. Gas condensing boiler has been designed as a source of heat for the heating system as well as water storage heater. The water storage heater is located in the boiler room in the ground floor. Areas of the heating surfaces are panel radiators and tubular and design elements. Electrical heating cable were used for the rooms with limited space.
