  1. 1. Using exergy and optimization models to improve industrial energy systems towards sustainability

    Detta är en avhandling från Linköping : Linköpings universitet

    Författare :Mei Gong; Jinyue Yan; [2004]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TECHNOLOGY; TEKNIKVETENSKAP;

    Sammanfattning : With finite natural resources and large energy demands in the world, a sustainable development approach becomes increasingly important in the improvement of energy systems. The concept of sustainability is examined with relation to exergy flows on the earth. The present industrial society is obviously not sustainable. LÄS MER

  2. 2. Enhanced District Heating Technology : Maintaining Future System Feasibility

    Detta är en avhandling från Lund : Lund University Open Access

    Författare :Helge Averfalk; Sven Werner; Urban Persson; Mei Gong; Patrick Lauenburg; Kerstin Sernhed; Per-Olof Johansson Kallioniemi; Louise Ödlund; [2017]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : When heat demand and high temperature heat supply gradually decreases in the future, then it will effect district heating systems ability to compete on the heat market. A good way to mitigate less district heating feasibility is to operate systems with lower temperature levels and the most conceivable way to achieve lower temperature levels is to decrease return temperatures.
