  1. 1. Resilient cooling technologies : Simulation study to determine the cooling capacity in old residentialbuildings located in mid-Sweden

    Magister-uppsats, Högskolan i Gävle/Energisystem och byggnadsteknik

    Författare :Ali Talib Ali; [2022]
    Nyckelord :cooling; cooling demand; absorption chiller; absorption refrigeration; district cooling; primary energy; resilience; residential buildings; old buildings; cooling capacity.;

    Sammanfattning : The Long-term changes in the climate conditions have increased the need foradequate thermal comfort systems. These alternations influence extremeevents, which their intensity and frequency have increased over the past years.Moreover, this study focuses on space cooling and parameters that the systemshould have to be considered as resilient.

    Sammanfattning : Thermochemical heat storage (TCS) is a thermal energy storage (TES) technology used to store thermal energy for later use. TCS can provide heating or cooling services from intermittently available thermal energy, often low grade waste heat. LÄS MER

  4. 3. Adaptation of Solar Energy Driven Absorption Chillers for Air Conditioning in Commercial Building

    Master-uppsats, Högskolan i Gävle/Avdelningen för bygg- energi- och miljöteknik

    Författare :Ranjith Shantha De Silva Kalinga; [2017]
    Nyckelord :;

    Sammanfattning : The most recent analysis of energy usage in the country reveled that nearly 50% of the power generation is used for air conditioning and mechanical ventilation most of which is used by commercial organizations. The grid generation mix that contains a high percentage of fossil fuel makes such energy usage environment unfriendly. LÄS MER

  5. 4. Solar-Biomass hybrid system for process heat supply in medium scale hotels in Sri Lanka

    Master-uppsats, KTH/Kraft- och värmeteknologi

    Författare :Asela M.A.J. Abeywardana; [2016]
    Nyckelord :;

    Sammanfattning : This study aimed at evaluating and demonstrating the feasibility of using Concentrated Solar Thermal technology combined with biomass energy technology as a hybrid renewable energy system to supply the process heat requirements in small scale industries in Sri Lanka.
