  1. 1. Energy Efficiency Improvements of Tumble Dryers -Technical Development, Laundry Habits and Energy Labelling

    University dissertation from Karlstad : Karlstad University

    Author : Lena Stawreberg; Karlstads universitet.; [2011]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; drying; domestic; energy efficiency; textile; energy labelling standard; TECHNOLOGY Engineering mechanics Mechanical and thermal engineering Thermal energy engineering; TEKNIKVETENSKAP Teknisk mekanik Mekanisk och termisk energiteknik Termisk energiteknik; Miljö- och energisystem; Environmental and Energy Systems;

    Abstract : Tumble dryers are becoming more and more common in ordinary households as a complement to the washing machine. Tumble dryers offer a fast drying cycle independent on weather conditions and require small space. They do, however, considering the large number of units use a large amount of electricity.

  2. 2. Postoperative recovery development of a multi-dimensional questionnaire for assessment of Recovery

    University dissertation from Örebro : Örebro universitet

    Author : Renée Allvin; Örebro universitet.; [2009]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Concept analysis; experiences; postoperative recovery; questionnaire; recovery profile; reliability; validity; MEDICINE Surgery; MEDICIN Kirurgi; Surgery; Kirurgi;

    Abstract : This thesis aims to present a multi-dimensional instrument for self-assessment of progress in postoperative recovery. The author employs different research paradigms and methodologies to achieve this aim.Walker and Avant’s approach to concept analysis was used to examine the basic elements of postoperative recovery (Study I).

  3. 3. District heating in future Europe Modelling expansion potentials and mapping heat synergy regions

    University dissertation from Göteborg : Chalmers University of Technology

    Author : Urban Persson; [2015]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; district heating; energy efficiency; distribution capital cost; heat demand density; plot ratio; excess heat recovery; sequential energy supply; heat utilisation rate; effective width;

    Abstract : This thesis presents a set of methodologies and approaches to investigate and determine the extent by which district heating can contribute to improved energy system efficiency and reduced carbon dioxide emissions in future Europe. The main motivation for suggesting large-scale implementation of district heating as a structural energy efficiency measure to obtain these objectives originates essentially in the predicament that a majority of European buildings today remain highly dependent on fossil fuels to provide energy needed for space heating and hot water preparation.

  4. 4. Biofuels from Kraft Black Liquor : Pilot-Scale Gasification Development and Techno-Economic Evaluation of Industrially Relevant Biofuel Production Pathways

    University dissertation from Luleå University of Technology

    Author : Yawer Jafri; Luleå tekniska universitet.; [2019]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; biofuels; black liquor; pyrolysis oil; gasification; drop-in; energy systems; techno-economic; Energiteknik; Energy Engineering;

    Abstract : Fuel combustion for transport was responsible for 24% of EU-28 greenhouse gas (GHG) emissions in 2016. Member states are expected to ensure that the share of renewable energy in the transport sector is at least 14% by 2030. Some countries, such as Sweden, have more ambitious targets. READ MORE

  5. 5. Waste Heat Recovery in Heavy Duty Diesel Engines

    University dissertation from ; Chalmers tekniska högskola; Gothenburg

    Author : Jelmer Johannes Rijpkema; [2018]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Organic Flash Cycle; Heavy Duty Diesel Engine; Organic Rankine Cycle; Trilateral Flash Cycle; Transcritical Rankine Cycle; Internal Combustion Engines; Waste Heat Recovery;

    Abstract : Over 50% of the energy released by burning fuel in a truck engine is lost as heat rather than being used to propel the vehicle. A promising method for capturing and reusing this heat, and thereby improving engine efficiency, is to exploit thermodynamic cycles for waste heat recovery (WHR). READ MORE
