  1. 1. District Heating for Residential Areas with Single-Family Housing -with Special Emphasis on Domestic Hot Water Comfort

    Författare :Tommy Persson; Energihushållning; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; low heat density; District heating; single-family housing; domestic hot water comfort; domestic hot water control; heat losses; supply temperature; thermostatic valves; Energiforskning; Energy research; marketing strategies; market penetration;

    Sammanfattning : The concept of district heating (DH) involves centralised heat production where heat is distributed to consumers via a piping network. It is essential that benefits achieved from concentrated, large-scale production instead of local production in each building exceed the costs associated with heat distribution. LÄS MER

  3. 2. District Heating Substations. Performance, Operation and Design

    Författare :Janusz Wollerstrand; Energihushållning; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; extreme value; heater; sizing; domestic hot water; drag reducing additives; microbial fouling; heat exchanger fouling; simulation; design; performance; District heating; substation; Energy research; Energiforskning;

    Sammanfattning : This thesis work is concerned with the efficient layout and operation of substations, i.e. those district heating (DH) system units which connect the network and internal building heating systems, such as radiator heating systems and domestic hot water distribution networks.

  4. 3. Energy Efficient Textile Drying

    Författare :Lena Brunzell; Bengt Månsson; Roger Renström; Jonas Berghel; Odilio Alves-Filho; Karlstads universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; tumble dryer; drying; textile; energy and mass balance; control strategy; Engineering mechanics; Teknisk mekanik; Miljö- och energisystem; Environmental and Energy Systems;

    Sammanfattning : Traditionally, textiles were dried outdoors with the wind and the sun enhancing the drying process. Tumble dryers offer a fast and convenient way of drying textiles independent of weather conditions. Tumble dryers, however, consume large amounts of electrical energy. LÄS MER

  5. 4. Effekten av effekten. Elanvändning och laststyrning i elvärmda småhus ur kund- och företagsperspektiv. Fallstudier

    Författare :Kerstin Sernhed; Institutionen för energivetenskaper; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; energianvändning; tariffer; effekt; laststyrning; småhus;

    Sammanfattning : Electricity must be produced at the same time as it is used. This necessitates flexibility in the electricity production and electricity networks. Until recently, the increase in electricity demand and peak power demand has been met by expansion of the electricity production. LÄS MER

  7. 5. Elbesparing med pelletkaminer och solvärme i direktelvärmda småhus

    Författare :Tomas Persson; Högskolan Dalarna; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Pellet; Pellets; Kaminer; Småhus; uppvärmning; Solvärme; Elvärme; konvertering; Biobränsle; Systemlösningar;

    Sammanfattning : The aim of this study was to investigate how electricallyheated houses can be converted to using wood pellet and solarheating. There are a large number of wood pellet stoves on themarket. Many stoves have a water jacket, which gives anopportunity to distribute the heat to domestic hot water and aradiator heating system.
