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

    Author : Bengt Bergsten; [2009]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; pilot plant; cooling tower; simulation; low energy cooling; cooling tower model; free cooling; chilled beams; evaporative cooling; commercial buildings; hydronic cooling system;

    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

    Author : Bengt Bergsten; [2004]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; cooling tower; commercial buildings; simulation; low energy cooling; evaporative cooling; hydronic cooling system; internal heat gain; free cooling; chilled beams; methodology;

    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. 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

  5. 5. Structure determination of beam sensitive crystals by rotation electron diffraction the impact of sample cooling

    University dissertation from Stockholm : Department of Materials and Environmental Chemistry, Stockholm University

    Author : Fei Peng; Stockholms universitet.; [2017]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; electron crystallography; rotation electron diffraction; structure determination; cooling; oorganisk kemi; Inorganic Chemistry;

    Abstract : Electron crystallography is complementary to X-ray crystallography. Single crystal X-ray diffraction requires the size of a crystal to be larger than about 5 × 5 × 5 μm3 while a TEM allows a million times smaller crystals being studied. This advantage of electron crystallography has been used to solve new structures of small crystals. READ MORE
