  1. 16. Importance of the demand-supply balance in district heating systems

    Författare :Dmytro Romanchenko; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; flexibility; Space heating; demand response; buildings; optimisation; thermal energy storage; district heating;

    Sammanfattning : In line with global efforts directed against climate change, the building sector will have to undergo significant changes in terms of its energy use, along with the transformation of the energy system. The scope of this thesis is limited to the energy supply and demand within district heating (DH) systems, with the emphasis on the space heating demand in buildings. LÄS MER

  3. 17. Hydronic Heating Systems The Effect of Design on System Sensitivity

    Författare :Anders Trüschel; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; shunt group; controllability; district heating; room temperature; air heater; heating coil; thermal power output; deviations; water return temperature; valve group; hydronic heating; radiator system; P-band;

    Sammanfattning : This thesis starts from the recognition that a hydronic heating system can be optimised, but can never be totally perfect. Sooner or later, in practice, deviations - caused by one or more components having slightly different characteristics or settings than they are assumed or supposed to have - arise. LÄS MER

  4. 18. District Heating Substations. Performance, Operation and Design

    Författare :Janusz Wollerstrand; Energihushållning; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; extreme value; heater; sizing; domestic hot water; drag reducing additives; microbial fouling; heat exchanger fouling; simulation; design; performance; District heating; substation; Energy research; Energiforskning;

    Sammanfattning : This thesis work is concerned with the efficient layout and operation of substations, i.e. those district heating (DH) system units which connect the network and internal building heating systems, such as radiator heating systems and domestic hot water distribution networks.

  7. 20. The future load curve of the Swedish building stock – Interactions between the heating load and district heating

    Författare :Dmytro Romanchenko; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; thermal energy storage; District heating; demand response; buildings; optimisation; space heating;

    Sammanfattning : In line with global efforts directed against climate change, the building sector is required to undergo significant changes in terms of its energy management. This is the case for both the use of energy (reduced energy consumption) and the supply of energy (heat and electricity), and how these two interact. LÄS MER
