  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.

    Abstract : Popular Abstract in Swedish Denna avhandling handlar om energieffektiva fönstersystem i svenska byggnader. Simuleringar av energianvändningen har gjorts för både småhus och kontor för att bedöma effekterna av olika fönsterval på energibehov och inneklimat. READ MORE

  4. 4. Thermal models of buildings : determination of temperatures, heating and cooling loads : theories, models and computer programs

    University dissertation from Department of Building Science, Lund Institute of Technology

    Author : Kurt Källblad; Lunds universitet.; Lund University.; [1998]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Building construction; Computer Programs; Windows; Infiltration; Comfort; Walls; Indoor Climate; Climate; Ventilation; Cooling Load; Heating Load; Buildings; Thermal Models; Building Physics; Energy; Byggnadsteknik;

    Abstract : The need to estimate indoor temperatures, heating or cooling load and energy requirements for buildings arises in many stages of a buildings life cycle, e.g. at the early layout stage, during the design of a building and for energy retrofitting planning. Other purposes are to meat the authorities requirements given in building codes. READ MORE

  5. 5. Experimental study of an intermittent ventilation system in high occupancy spaces

    University dissertation from Gävle : Gävle University Press

    Author : Alan Kabanshi; Högskolan i Gävle.; [2017]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Intermittent airflow; Indoor air quality; Perceived air quality; Thermal sensation; thermal comfort; Air movement acceptability; Convective cooling; Cooling effect.; Intermittent luftflöde; Luftstrålar; Upplevd luftkvalitet; Termisk komfort; Acceptans av luftrörelser; Konvektiv kylning; Kyleffekt.;

    Abstract : Spaces with high occupancy density like classrooms are challenging to ventilate and use a lot of energy to maintain comfort. Usually, a compromise is made between low energy use and good Indoor Environmental Quality (IEQ), of which poor IEQ has consequences for occupants’ health, productivity and comfort. READ MORE
