  1. 1. Performance assessment in district cooling networks using distributed cold storages : A case study

    Master-uppsats, KTH/Energiteknik

    Författare :Zinar Bilek; [2020]
    Nyckelord :;

    Sammanfattning : District cooling is a technology that has been gaining traction lately due to increased demand from the commercial and industrial sectors, especially in dense urban areas such as Stockholm. A literature study found that customers such as hospitals, offices, malls and data centres all depend on both comfort cooling and process cooling. LÄS MER

  2. 2. Energy poverty and the elderly-care: Exploring energy poverty in the elderly-care through case studies with social welfare organizations in Taiwan

    Master-uppsats, Lunds universitet/Internationella miljöinstitutet

    Författare :Tzu Ling Kuo; [2020]
    Nyckelord :Science General;

    Sammanfattning : The topic of energy poverty has recently gained prominence amongst researchers and academia in Taiwan within the context of rising energy prices and low emission energy transitions. Social welfare organizations (SWOs) that provide 24-hour residence and care for vulnerable populations, such as the elderly and disabled, highly depend on various energy services and are likely to be significantly affected due to rising energy prices, adding to their existing financial pressure.

  4. 4. Möjligheter till ökad driftsäkerhet och kostnadseffektivitet i fjärrvärmenät : En simulerings- och optimeringsstudie på Kalmar Energi

    Master-uppsats, Linköpings universitet/Energisystem; Linköpings universitet/Energisystem

    Författare :Carl Torstensson; Daniel Nordborg; [2019]
    Nyckelord :District Heating; NetSim; Simulation; Optimization; Bypass; Bottleneck; Differential pressure; DH; Fjärrvärme; Förbikoppling; Flaskhals; NetSim; Simulering; Optimering; Differenstryck;

    Sammanfattning : Since district heating is the most common way of space heatingin Sweden, continual improvements of theefficiency of production and distribution of district heating is crucial. The purposeof this report is therefore to, using Kalmar Energi as an example, study how the production and distribution of district heating is affected by introducing a bypass pipeat a critical point in the network, and to investigate howcost efficiency might be achieved.

    Sammanfattning : This thesis provides a standardized method to measure accuracy for engine and gearbox sensors. Accuracy is defined by ISO 5725, which states that trueness and precision need to be known to provide a metric for accuracy. However, obtaining and processing the data required for this is not straight forward. LÄS MER
