  1. 41. Integrating Heat Pumps into Smart Grids

    Författare :David Fischer; Björn Palm; Georges Laurent; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energy Technology; Energiteknik;

    Sammanfattning : Transforming our energy system towards 100% renewable energy sources requires radical changes across all energy sectors. Heat pumps as efficient heat generation technology link the electricity and heat sector. From 2010 to 2015 between 750,000 and 800,000 heat pumps have been sold every year across Europe. LÄS MER

  4. 43. Economic analysis of air-water heat pump technologies with a screening method

    Författare :Gunda Mader; Björn E. Palm; José Miguel Corberan; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Early on in the process of product development a decision has to be made which technologies to focus on. Under a purely techno-economic viewpoint for a heat pump only these technologies should be considered which maximize heat pump performance for a given cost. LÄS MER

  5. 44. Developments in Ground Heat Storage Modeling

    Författare :Alberto Lazzarotto; Björk Folke; Michel Bernier; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Borehole fields; g-functions; network; inclined; integrated design; Energy Technology; Energiteknik; Byggvetenskap; Civil and Architectural Engineering;

    Sammanfattning : Ground heat storage systems can play an important role for the reduction of green house gases emissions by increasing the exploitation of renewable energy sources and “waste heat” with a consequent diminution of the use of fossil fuels.A ground heat storage consists in an array of vertical boreholes placed in such a way that promotes the mutual thermal interaction between the ground heat exchangers creating the necessary conditions required to effectively store and retrieve heat.

  7. 45. Process Integration of Industrial Heat Pumps in Grass-Root and Retrofit Situations

    Författare :Erik Wallin; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; process integration; pinch technology; retrofit; industrial heat pumps; grass-root;

    Sammanfattning : In several works, methods for process integration of heat pumps (HPs) have been developed, which in turn have been used for case studies in different industrial types. HP integration has thus proven to be a promising technique for utility savings and attractive payback periods. LÄS MER
