    Sammanfattning : The transmission of airborne aerosols in a ventilated indoor environment has become highly relevant since the Covid-19 outbreak. Initially, Covid-19 was only assumed to be spread via droplet and contact infection, but research and known outbreaks show that airborne transmission via aerosols occurs. LÄS MER

  3. 2. Utvärdering av avklingnings- och homogenspridningsmetoden vid jämförelse mellan deplacerande, omblandande och utjämnande ventilation

    Uppsats för yrkesexamina på grundnivå, Lunds universitet/Avdelningen för Installations- och klimatiseringslära

    Författare :Joakim Sandell; [2017]
    Nyckelord :Avklingningsmetoden; Homogenspridningsmetoden; Deplacerande ventilation; Omblandande ventilation; Utjämnande ventilation; Spårgasmätningar; Technology and Engineering;

    Sammanfattning : People spend a lot of time indoors, closer to 90% of their lifetime. To obtain a good indoor climate with good air quality buildings need to be ventilated. Therefore, they are often equipped with mechanical ventilation systems. Nevertheless, SBS (Sick Building Syndrome) is a serious problem. LÄS MER

  4. 3. Ventilation efficiency measurements - a comparison between three supply air methods

    Master-uppsats, Lunds universitet/Avdelningen för Energi och byggnadsdesign

    Författare :Max Henriksson; Henrik Nilsson; [2016]
    Nyckelord :Ventilation efficiency; air exchange efficiency; local ventilation index; mean age of air; comparison; mixed ventilation; displacement ventilation; Technology and Engineering;

    Sammanfattning : This study compares the two traditional ventilation methods ; mixed ventilation and displacement ventilation, with a new type of dif fuser which attempts to solve the problem with blockage of the diffuser for the displacement ventilation. This new diffuser called Airshower is a product developed by Airson engineering AB whom is also the company where all simulations and tests for this study were performed in a built office space.
