  1. 1. Effektivisering av pump- och fläktdrifter i byggnader. Elanvändning och systemlösningar

    Författare :Caroline S Markusson; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; damper; efficiency; electric energy; authority; demand; control; variable speed; valve; heating; cooling; fans; electric motors; ventilation; pumps;

    Sammanfattning : In this licentiate work the energy savings potential by more efficient pump and fan operation in buildings has been examined. The national savings potential in Sweden has been estimated based on available statistics and on information gained in a limited inventory. The estimated energy use for pump operation in residential and commercial (i.e. LÄS MER

  3. 2. Efficiency of building related pump and fan operation - Application and system solutions

    Författare :Caroline S Markusson; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; motor drive; control-on-demand; hydronic systems; air systems; electric motor; variable speed; decentralized systems; pump; electric energy; fan; local systems; efficiency;

    Sammanfattning : The electric energy use in Swedish non-industrial buildings is 71 TWh per year out of which 30 TWh per year is used for the operation of technical systems. A significant part of those 30 TWh/year is used for pump and fan operation. The Swedish parliament decided in 2009 on a national energy and climate plan. LÄS MER

    Sammanfattning : Energy from solar photovoltaic (PV) are generated as direct current (DC) and almost all of today’s electrical loads in residential buildings, household appliances and HVAC system (Heating Ventilation and Air-conditioning) are operated on DC. For a conventional alternating current (AC) distribution system this requires the need for multiple conversion steps before the final user-stage. LÄS MER
