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

    Author : Bengt Bergsten; Chalmers tekniska högskola; []
    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

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

    Author : Bengt Bergsten; Chalmers tekniska högskola; []
    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.

  5. 3. Temperature measurements on silicon core fibers during CO2 laser processing

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

    Abstract : 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. READ MORE

  6. 4. Developing Humidified Gas Turbine Cycles

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

    Abstract : 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. READ MORE

  7. 5. High Voltage DC-biased Oil Type Medium Frequency Transformer; A Green Solution for Series DC Wind Park Concept

    Author : Mohammad Kharezy; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; High voltage DC; Insulation design; Offshore wind farm; Leakage inductance; High power isolated DC DC converter; Dual active bridge; Medium-frequency power transformer; Parasitic capacitance; HVDC;

    Abstract : The electric energy generated by remote offshore wind parks is transported to the consumers using high voltage submarine cables. On the generation site, such transmissions are realized today by collecting the energy produced by several wind turbines in a bulky and expensive transformer placed on a dedicated platform. READ MORE
