    Sammanfattning : Fuel cell systems are becoming more commonplace as a power generation method and are being researched, developed, and explored for commercial use, including portable fuel cells that appear in laptops, phones, and of course, chargers. This thesis examines a model constructed on inspiration from the myFC PowerTrekk, a portable fuel cell charger, using COMSOL Multiphysics, a finite element analysis software. LÄS MER

  3. 2. Energy efficient space and water heating in a university building

    M1-uppsats, KTH/Strömnings- och klimatteknik

    Författare :Birte Schnurr; [2013]
    Nyckelord :space; water heating system; hot water supply; Norra Djurgården 43:12;

    Sammanfattning : The building Norra Djurgården 43:12 on the main campus of the Royal Institute of Technology (KTH)  in Stockholm will be retrofitted as students from the exter- nal campus Haninge will be moved there. This occasion is supposed to be used to improve the facility’s energy efficiency. LÄS MER
