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

    Författare :Bengt Bergsten; Chalmers University of Technology; []
    Nyckelord :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;

    Sammanfattning : 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. LÄS MER

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

    Författare :Bengt Bergsten; Chalmers University of Technology; []
    Nyckelord :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;

    Sammanfattning : 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. Temperature measurements on silicon core fibers during CO2 laser processing

    Författare :Korbinian Mühlberger; Michael Fokine; Valerio Pruneri; KTH; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Physics; Fysik;

    Sammanfattning : This thesis presents temperature measurements on silicon core optical fibers during CO2 laser processing. Silicon core fibers are a new type of fiber offering a unique platform to combine the optoelectronic properties of silicon and the possibilities of the optical fiber platform. LÄS MER

  4. 4. Developing Humidified Gas Turbine Cycles

    Författare :Michael Bartlett; KTH; []
    Nyckelord :advanced gas turbine cycles; evaporative; humidified; power; heat and power; ;

    Sammanfattning : As a result of their unique heat recovery properties,Humidified Gas Turbine (HGT) cycles have the potential todeliver resource-effective energy to society. The EvaporativeGas Turbine (EvGT) Consortium in Sweden has been studying thesetypes of cycles for nearly a decade, but now stands at acrossroads, with commercial demonstration remaining. LÄS MER
