  2. 1. Sustainable building ventilation solutions with heat recovery from waste heat

    Author : Behrouz Nourozi; Sture Holmberg; Adnan Ploskic; Qian Wang; Shia-Hui Peng; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; wastewater heat recovery; balanced mechanical ventilation; defrosting reduction; heat recovery efficiency; thermal load shifting; renewables; Byggvetenskap; Civil and Architectural Engineering;

    Abstract : The energy used by building sector accounts for approximately 40% of the total energy usage. In residential buildings, 30-60% of this energy is used for space heating which is mainly wasted by transmission heat losses. A share of 20-30% is lost by the discarded residential wastewater and the rest is devoted to ventilation heat loss. READ MORE

  4. 2. A System Perspective on District Heating and Waste Incineration

    Author : Kristina Holmgren; Björn Karlsson; Anna Björklund; Linköpings universitet; []
    Keywords : Energy recovery; District heating; Waste incineration; Waste management; Environmental; Material recovery; TECHNOLOGY; TEKNIKVETENSKAP;

    Abstract : Energy recovery by waste incineration has a double function as waste treatment method and supplier of electricity and/or heat, thereby linking the systems of energy and waste management. Both systems are undergoing great changes, mainly due to new regulations. READ MORE

  5. 3. Thermoelectric Ba8Ga16Ge30 clathrates for waste heat recovery

    Author : Daniel Cederkrantz; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; thermal stability; substitution; thermal conductivity; Seebeck coefficient; electrical resistance; Clathrates; Ba8Ga16Ge30; waste heat recovery; semiconductors;

    Abstract : The modern, highly industrialized, society of today requires huge amounts of energy to function. This has resulted in a heavy dependence on the very energy efficient fossil fuels, a source of energy which of course is not infinite and we are slowly approaching the day when oil runs out.

  6. 4. Exhaust Heat Utilisation and Losses in Internal Combustion Engines with Focus on the Gas Exchange System

    Author : Habib Aghaali; Hans-Erik Ångström; Carlos Guardiola; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Turbocharger; heat transfer; heat loss; exhaust heat utilisation; waste heat recovery; turbocompound; divided exhaust period; internal combustion engine; gas exchange; pumping loss; variable valve timing; WHR; DEP; Turbo; värmeöverföring; värmeförluster; avgasvärme utnyttjande; förluster vid värmeåtervinning; turbocompound; delad avgasperiod; förbränningsmotor; gasväxling; pumpningsförlust; variabla ventiltider; WHR; DEP; Vehicle and Maritime Engineering; Farkostteknik; Energy Technology; Energiteknik;

    Abstract : Exhaust gas energy recovery should be considered in improving fuel economy of internal combustion engines. A large portion of fuel energy is wasted through the exhaust of internal combustion engines. Turbocharger and turbocompound can, however, recover part of this wasted heat. READ MORE

  7. 5. Evaluating the utilisation of industrial excess heat from an energy systems perspective

    Author : Igor Cruz; Magnus Wallén; Mats Söderström; Maria Johansson; Danica Djuric Ilic; Johanna Mossberg; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Industrial excess heat; Waste heat; Heat recovery; Greenhouse gas emissions;

    Abstract : Sweden aims to achieve climate neutrality by 2045. The need to immediately reduce greenhouse gas emissions in order to achieve climate targets affects industry directly. The pulp and paper sector is responsible for more than 50% of industrial energy use in Sweden. READ MORE
