Účinnost zdrojů a nepřímotopný ohřev teplé vody / Boiler efficiency and indirect heating of hot water

Matůšů, Ondřej January 2019 (has links)
This diploma thesis deals with efficiency of heat sources and indirect heating of hot water. First part of this thesis is about heating of hot water, particulary indirect heating of hot water and it is all summarized in theoretical knowledge section. Second part deals with central heating and indirect heating of hot water in four floor flat house. The heat source for this object is cascade of two gas condensing boilers. In this building there are mostly used panel radiators. In the last, third part, I experimentaly deal with operational efficiency of heating sources with heating of hot water.

Provozní účinnosti zdrojů tepla / Operational efficiency of boilers

Doležal, Lukáš January 2019 (has links)
The topic of this diploma thesis is the operational efficiency of heat sources. The work had several goals. The first was to determine the efficiency of the wood boiler according to available calculation methods and to compare the methods among them. The second was to determine the difference in the performance of the flue gas analyzer and the real calculation. Further, to determine the efficiency of a boiler firing different wood species - spruce and hornbeam based on their properties and elemental composition. Experimental measurement of various operating states of effectiveness took place in an older two-generation family house, which was also the subject of the project part. Due to lack of project documentation, it was necessary to focus and plot the object. Afterwards, the building was thermally inspected and the design of the heating system and the reconstruction of the whole heating system was carried out. The project was developed in two variants for two different heat sources - a heat pump and a solid fuel boiler for heating and water preparation. The thesis deals with the technical report, the conceptual solution of the related professions, the evaluation of the heat source variants and the project documentation.

Vytápění bytového domu / Heating of flat house

Jára, Marek January 2020 (has links)
The theme of this diploma thesis is to design heating of the flat house. The theoretical part of this diploma thesis is about exhaust gases paths. The calculation part of this diploma thesis contains the design of the heating system by panel heaters, floor convectors and underfloor heating system. The heat source is the system of cascade-connected gas condensing boilers. The rest of this part are the calculations of the preparation of hot water, design of hot water storage tank and another necessary equipment of the system. The part Project is about technical report and simulation of behaviour of underfloor heating system in various marginal conditions.

Provozní účinnost kotlů / Working efficiency of boilers

Rejsa, Vojtěch January 2020 (has links)
This work deals with the determination of the operational efficiency of solid fules boilers for their inclusion in the relevant emission class according to ČSN EN 303-5. Two steel boilers of the same manufacturer, type and performance but of different ages, were measured. The experimental measurments in the real operation of the boilers were carrien out during the combustion of two types of fuels, namely brown coal and spruce wood.The operational efficiency of the monitored sources was calculated from the measured data using both direct and undirect methods. The found efficiency of the boilers corresponds to the expected values, due to their construction, age and the way of using individual components and regulations. In the project part of this work there is a proposal of heating of the family house for the condition of the building before and after the insulation. The calculation was made for the solid fuel boiler and heat pump. The building is heated by radiators and floor heating. The design of the whole system, technical report and project documentation were prepared for each variant.

Velkoplošné systémy pro vytápění a chlazení / Heating and cooling systems

Pavlíček, Radek Unknown Date (has links)
The topic of this diploma thesis is large area heating and cooling systems. Theoretical part of this thesis is focused on thermal comfort of people in interier and on theoretical calculation of heat transfer and on large area heating and cooling systems. Second part is devided to two variants. First variant is design of a heating system in kindergarden with floor heating combined with plate heating radiators. Second variant is heating system with only plate heating radiators. As source of heat is used condensing gas boiler. Part of a design is preparation of hot water. Experimental part of the thesis contains measurements of coefficient of heat transfer in floor heating and wall heating.

Horský hotel / Mountain hotel

Sibilla, Luboš January 2013 (has links)
Diploma thesis is focused on design of a new hotel in mountain surrounding with one underground floor and five stories. The hotel has 53rooms for guests from the second to the fifth floor and two rooms for employees of hotel on the fifth floor, what means 106 beds for guests. The hotel is equipped indoor swimming pool 25x10meters, its own kitchen, dining hall, sauna, massages and Conference hall. The object consists of four dilatation units – accommodation sides and common central part and swimming pool. Roof construction is created by huge wooden truss from the second floor to the fifth floor, which sequentially subsides and formed by 70 dormers. Angle of the roof is 46° and 23°, and surface coating is smooth titanium zinc sheet. Load bearing system of whole object is designed as irregular reinforced concrete monolithic skeleton from concrete C30/37 with prestressed elements and based on prestressed reinforced concrete slab. The cladding is designed from ceramic bricks with inner additional insulation and additional insulation on outer surface, which is covered by facade with ventilated air gap, designed from cement-fibers boards, which are by color and structure imitating natural stone. Each accommodation floor is divided into two accommodation sides, central part with central stairs and two personal elevators. Each accommodation side has two protected escape routes and one fire evacuation lift. On the Ground floor, there is the reception, the dining hall, the pool hall and offices. On the underground floor, there is wellness center for guests of the hotel, technologies for the pool, HVAC engine room and kitchen. In all object, there are designed different types of hanging ceilings, because of attendance of stabile sprinkler system. In the pool hall, there will be acoustic hanging ceiling. Heating will be procured by combination of biomass boiler and heat pumps, which will be used mainly for deck heating in rooms in accommodation floors.

Účinnost rozvodů tepla / The efficiency of heat distribution

Vích, Pavel January 2015 (has links)
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.
