  2. 21. Energy Efficient Textile Drying

    Author : Lena Brunzell; Bengt Månsson; Roger Renström; Jonas Berghel; Odilio Alves-Filho; Karlstads universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; tumble dryer; drying; textile; energy and mass balance; control strategy; Engineering mechanics; Teknisk mekanik; Miljö- och energisystem; Environmental and Energy Systems;

    Abstract : Traditionally, textiles were dried outdoors with the wind and the sun enhancing the drying process. Tumble dryers offer a fast and convenient way of drying textiles independent of weather conditions. Tumble dryers, however, consume large amounts of electrical energy. READ MORE

  4. 22. Analysis of PEM Fuel Cell Stacks and Systems with Water/Thermal Balances

    Author : Takamasa Ito; Värmeöverföring; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Thermal engineering; applied thermodynamics; Termisk teknik; termodynamik; PEM Fuel Cell Systems ; Water Thermal Balances ; Heat Exchangers ; PEM Fuel Cell Stacks ;

    Abstract : The Proton Exchange Membrane (PEM) fuel cell has been investigated for a long time, and is regarded as a new energy source for various applications, such as portable, stationary and automotive ones. However, due to the shortage of the infrastructure in the society, the high cost, the difficulty of the water/thermal management, etc. READ MORE

  5. 23. Life cycle primary energy use and carbon emission of residential buildings

    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Byggteknik;

    Abstract : In this thesis, the primary energy use and carbon emissions of residential buildings are studied using a system analysis methodology with a life cycle perspective. The analysis includes production, operation, retrofitting and end-of-life phases and encompasses the entire natural resource chain. READ MORE

  6. 24. Computational Analysis and Modeling Techniques for Monolithic Membrane Reactors Related to CO2 Free Power Processes

    Author : Faruk Selimovic; Värmeöverföring; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Oxygen Transfer Membrane OTM ; High Temperature Heat Exchanger HTHEX ; Monolithic Heat Exchanger; Advanced Zero Emission Power Plant AZEP ; Mixed Ionic-Electronic Conducting Membranes MIEC ; Computational Fluid Dynamics CFD ;

    Abstract : Funded by European Community and Swiss government research project AZEP (Advanced Zero Emission Power Plant), the project was carried out at the Department of Energy Sciences at Lund Faculty of Engineering (LTH). The project addressed the development of a specific, zero emissions, gas turbine-based, power generation process to reduce local and global emissions in a cost-effective way. READ MORE

  7. 25. Gravure vs. Web-offset! : a changing world in publication printing 1986-2006

    Author : Anders Bjurstedt; Nils Enlund; Robert Chung; KTH; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Mass communication; Masskommunikation;

    Abstract : The European publication printing industry and its markets have undergone profound structural changes between 1986 and 2006. This thesis is an investigation of these changes and of how the publication industry has been affected, as well as of the balance between publication gravure and commercial heat-set web-offset.
