  1. 1. Evaporative Cooling Tower and Chilled Beams. Design Aspects for Cooling in Office Buildings in Northern Europe

    University dissertation from Chalmers University of Technology

    Author : Bengt Bergsten; Chalmers tekniska högskola.; Chalmers University of Technology.; [2009]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Byggnadsteknik; Building engineering; free cooling; low energy cooling; evaporative cooling; commercial buildings; cooling tower; cooling tower model; simulation; hydronic cooling system; chilled beams; pilot plant;

    Abstract : The purpose of this thesis is to examine a comfort cooling system consisting of a hydronic cooling system with an evaporative cooling tower and chilled beams. The system has no conventional chiller. READ MORE

  2. 2. Free cooling in commercial buildings. Application with evaporative cooling tower and chilled beams

    University dissertation from Chalmers University of Technology

    Author : Bengt Bergsten; Chalmers tekniska högskola.; Chalmers University of Technology.; [2004]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Byggnadsteknik; Building engineering; free cooling; low energy cooling; evaporative cooling; commercial buildings; internal heat gain; methodology; cooling tower; simulation; hydronic cooling system; chilled beams;

    Abstract : The use of electricity in commercial buildings has increased over the last decades. One major cause is the rapid escalation of air conditioning equipment together with a growth of internal heat gains originating mainly from an increased amount of office equipment, which also use electric energy, and high levels of solar irradiation.

  3. 3. Cooling and dopamine

    University dissertation from Roger Roscher, Dept. of Anaesthesiology, Rikshospitalet, N-0027 Oslo, Norway

    Author : Roger Roscher; Lunds universitet.; Lund University.; [2001]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Anaesthesiology; electrophysiology; cooling; Hypothermia; swine; lung transplantation; organ preservation; dopamine; circulation; contractility; oxygenation; intensive care; Anestesiologi; intensivvård;

    Abstract : Popular Abstract in Swedish Syftet med denna studie var att försöka kartlägga effekterna av ytkylning och dopamins effekter på hjärta och blodcirkulation samt på syrgastransport och syrgasförbrukning efter ytkylning. Faran för att bli oavsiktligt nedkyld är störst om immobiliserande skador har uppstått samtidigt som man exponeras för kyla, speciellt om kylan är kombinerad med väta. READ MORE

  4. 4. Experimental Studies of Effusion Cooling

    University dissertation from Chalmers University of Technology

    Author : Bernhard Gustafsson; Chalmers tekniska högskola.; Chalmers University of Technology.; [2001]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Fysik; Physics; Teknisk mekanik; Engineering mechanics; effusion cooling; full coverage film cooling; film cooling; jet in crossflow; infrared thermography; laser-Doppler anemometry; flow visualization;

    Abstract : The desire to increase the efficiency of jet engines, has led to an increase in the temperature in the combustion chambers and in the turbine stage. There is thus an interest in efficient cooling methods. Film cooling and effusion cooling are often used where there is a great heat load. READ MORE

  5. 5. Heat driven cooling in district energy systems

    University dissertation from Stockholm : Kemiteknik

    Author : Magnus Rydstrand; KTH.; [2004]
    Keywords : District heating; district cooling; thermal storage; humidified gas turbines; combined heat and power; cooling;

    Abstract : Abstract The threat of global warming, caused by increasingemissions of carbon dioxide (CO2), is one reason why cooling supply systems mustwork more efficiently in the world today. An increasing share,currently between 10 and 20%, of the global output ofelectricity is consumed to produce cooling. READ MORE
