    Nyckelord :Sprinkler activation; fire sprinkler; fire suppression; actuation; sloping ceiling; slope; CFD; Computational Fluid Dynamics; Fire Dynamics Simulator; FDS; FDS 6; NFPA 13; sprinkler activation pattern; sprinkler suppression.; Technology and Engineering;

    Sammanfattning : The purpose of this report is to investigate the implications of installing sprinkler systems in ceilings with a ceiling slope exceeding the maximum permitted by NFPA 13, being 9.5 ° or 18.44 ° depending on the type of sprinkler system. LÄS MER

  2. 2. Freezing in Fire Sprinkler Systems During Activation at Low Temperatures

    Magister-uppsats, Lunds universitet/Institutionen för energivetenskaper

    Författare :Kamil Oskar Bialas; [2011]
    Nyckelord :Freezing Fire sprinkler system ice growth ; Technology and Engineering;

    Sammanfattning : The subject of this thesis is theoretical examination of freezing phenomena inside fire sprinkler systems during activation at low temperatures in the surroundings. Many sprinkler systems are installed in environments such that they must be operable at subfreezing temperature conditions. LÄS MER

  3. 3. Sprinkler för personskydd

    Kandidat-uppsats, Lunds universitet/Avdelningen för Brandteknik; Lunds universitet/Brandingenjörsprogrammet; Lunds universitet/Avdelningen för Riskhantering och Samhällssäkerhet

    Författare :Christian Hansson; [2003]
    Nyckelord :fractional incapacitation dose; carbon dioxide; carbon monoxide; oxygen; literature; Residential sprinkler; temperature; thermal radiation; Technology and Engineering;

    Sammanfattning : The report puts together existing experiences about residential sprinkler on issues as its ability to save lives in a fire, its reliability in activation and reasons for failure of fulfilling these tasks. The project also conducts a series of tests with activation of sprinkler in a room with a fire in order to record and evaluate the environment in the room after the sprinkler activated and compare it with a fire with no sprinkler present.

  4. 4. Brandteknisk riskvärdering av Linden köpcentrum, Norrköping

    L3-uppsats, Lunds universitet/Avdelningen för Brandteknik; Lunds universitet/Brandingenjörsprogrammet; Lunds universitet/Avdelningen för Riskhantering och Samhällssäkerhet

    Författare :Louise Abrahamsson; Daniel Ekström; Andreas Kräling; Lisa Åkesson; [2003]
    Nyckelord :Brandteknisk riskvärdering; varuhus; rökfyllnad; utrymning; personsäkerhet; ARGOS V4.4; FAST CFAST V3.1.7; FDS V3.1; SIMULEX V11.1.3; Linden.; Technology and Engineering;

    Sammanfattning : The report contains an evaluation of the fire safety at Linden shopping centre in Norrköping, Sweden. The evaluation concerns evacuation times, fire development, smoke filling and smoke layer temperatures. The modelling has been executed with the computer models FDS, ARGOS, AST/CFAST and SIMULEX which were validated with hand calculations. LÄS MER
