  2. 6. Performance of Compact Heat Exchanger in Non-Perpendicular Cooling Airflows

    Author : Lisa Henriksson; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Simulations; Angled; Experiments; Inclined; Heat transfer; Pressure drop; CFD; Heat exchanger;

    Abstract : During recent years the main focus in the vehicle industry has been on cutting the fuel consumption and emissions as well as improving the vehicle performance. To be able to meet these demands additional systems are being introduced into the vehicle. READ MORE

  4. 7. From Combined Heat and Power to Polygeneration

    Author : Fredrik Starfelt; Jinyue Yan; Eva Thorin; Umberto Desideri; Mälardalens högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energy- and Environmental Engineering; energi- och miljöteknik;

    Abstract : In order to reach targets on reducing greenhouse gas emissions from fossil resources it is necessary to reduce energy losses in production processes. In polygeneration, several processes are combined to complement each other to avoid sub-optimization of the standalone processes. READ MORE

  5. 8. Combined Assessment of Future Heat Supply and Demand - A Dynamic Systems Approach

    Author : Karl Vilén; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TIMES; Climate policy; Low heat demand housing; District heating; Heating system; Dynamic energy system modeling; Housing;

    Abstract : In order to meet climate change mitigation targets, the use of fossil fuels has to be reduced and, eventually, be phased out in all sectors. As the heating sector occupies a central place in energy systems, especially in Nordic countries, it is affected by and affects other energy sectors. READ MORE

  6. 9. Heat driven cooling in district energy systems

    Author : Magnus Rydstrand; KTH; []
    Keywords : District heating; district cooling; thermal storage; humidified gas turbines; combined heat and power; cooling;

    Abstract : Abstract The threat of global warming, caused by increasingemissions of carbon dioxide (CO2), is one reason why cooling supply systems mustwork more efficiently in the world today. An increasing share,currently between 10 and 20%, of the global output ofelectricity is consumed to produce cooling. READ MORE

  7. 10. 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
