  2. 11. Residential Electricity Use and Control - Technological Aspects

    Author : Gregory North; Energihushållning; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : The research report details the current outcomes of an investigation into ways to improve the control and use of electricity for both electric utilities and residential end-users. These improvements can be achieved through electrical control possibilities where specific electrical devices could be either removed or time-shifted to less demanding periods. READ MORE

  4. 12. On the Design of Residential Condensing Gas Boilers

    Author : Mikael Näslund; Energihushållning; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energy research; flue systems; modelling; efficiency; condensing boilers; space heating; natural gas; Energiforskning;

    Abstract : Two main topics are dealt with in this thesis. Firstly, the performance of condensing boilers with finned tube heat exchangers and premix burners is evaluated. Secondly, ways of avoiding condensate formation in the flue system are evaluated. READ MORE

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

    Author : Tommy Persson; Energihushållning; []
    Keywords : 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;

    Abstract : 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. READ MORE

  6. 14. Energy Services in Sweden - Customer Relations towards Increased Sustainability

    Author : Kerstin Sernhed; Energihushållning; []
    Keywords : demand-side management; district heating; electricity; Customer relations; district-heating marketing strategies; load management; feedback;

    Abstract : Energy use and supply are evident issues to consider for a sustainable development, where the economic, social and environmental aspects are all important. In large grid-bound systems, the supply of energy is usually a rather invisible activity and the contacts between household custo-mers and utilities are sometimes only repre-sented through the energy bill.

  7. 15. District Heating Substations. Performance, Operation and Design

    Author : Janusz Wollerstrand; Energihushållning; []
    Keywords : 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;

    Abstract : 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. READ MORE
