Provozní účinnosti zdrojů tepla / Operational efficiency of boilersDoležal, 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 houseJára, 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 boilersRejsa, 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 systemsPavlíček, 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.

Účinnost rozvodů tepla / The efficiency of heat distributionVích, 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.

Kvalita otopné vody pro zdroje tepla / Hot water quality for heatSnášelová, Tereza January 2017 (has links)
The diploma thesis focuses on assesment of water quality in heating systems. The experiment includes description of used methods and meters as well as analysis of collected samples. The theoretical part describes selected water properties, quality meters and sources of heat according to the material of their heat exchanger. This thesis processes design of heating system and hot water preparation for complex of administration buildings. The project includes calculations of heat losses, system proposal and two versions of possible heat source. The first version offers solution with condensing boiler with heat exchanger from stainless steel, while the second version uses condensing boiler with heat exchanger from aluminium and silicon. Both versions have their own solution of safety equipment and water treatment.
