  2. 1. A Silent Revolution : The Swedish Transition towards Heat Pumps, 1970-2015

    Author : Petter Johansson; Pär Blomkvist; Martin Vendel; Eric Giertz; Mats Fridlund; KTH; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; heat pumps; socio-technical transition; sustainability transition; industrial dynamics; value networks; coopetition; complementarities; strategic management; värmepumpar; socio-tekniska övergångar; hållbarhet; industriell dynamik; värdenätverk; coopetition; komplementariteter; företagsstrategi; Industriell ekonomi och organisation; Industrial Economics and Management;

    Abstract : Currently, more than half of all Swedish single-family houses have an installed heat pump and more heat is supplied by heat pumps in Sweden than in any other nation. Despite the enormous impact of heat pumps on the Swedish energy system, the transition towards their use has gone relatively unnoticed. READ MORE

  4. 2. Process Integration of Industrial Heat Pumps in Grass-Root and Retrofit Situations

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

    Abstract : 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. READ MORE

  5. 3. Two-Stage Industrial Heat Pumps - A Design Study

    Author : Michéle Brun; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : .... READ MORE

  6. 4. Large Heat Networks in District Heating Systems

    Author : Akram Sandvall; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; MARKAL; Waste heat; Energy system modeling;

    Abstract : District heating (DH) systems have experienced three generations since the 1880s. In chronological order, high temperature steam and pressurized hot water above and below 100 degrees have been used to carry heat over these three generations. READ MORE

  7. 5. Compression/Absorption cycles for large heat pumps - Systems simulations

    Author : Lena Åhlby; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : The compression/absorption cycle can, in many situations,give an improved performance compared to the single-fluidcompression heat pump. Also other advantages can beachieved such as the possibility to use an already knownrefrigerant within a new temperature range. READ MORE
