  2. 16. New process integration methods for heat-saving retrofit projects in industrial systems

    Author : Roger Nordman; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Process Integration; Heat Exchanger Network; Pulp and Paper; Method Development;

    Abstract : New graphical methods for HEN retrofit (further development of existing tools), release of usable excess heat and placement of supply tanks in HWWS systems have been developed. In addition, further development of the matrix method for HEN retrofit has been made. READ MORE

  4. 17. Advances in optimal design and retrofit of chemical processes with uncertain parameters - Applications in design of heat exchanger networks

    Author : Christian Langner; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Design under Uncertainty; Uncertainty Space; Process Integration; Managing Variations; Process Design; Flexibility Analysis;

    Abstract : There is widespread consensus that the omnipresent climate crisis demands humanity to rapidly reduce global greenhouse gas (GHG) emissions. To allow for such a rapid reduction, the industrial sector as a main contributor to GHG emissions needs to take immediate actions. READ MORE

  6. 19. Energy use and environmental impact from hotels on Adriatic Coast in Croatia : current status and future possibilities for HVAC systems

    Author : Vlasta Zanki Alujevic; Per Lundqvist; Dagnia Blumberga; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; HVAC systems; hotels; energy performance; energy efficiency; environmental savings; energy audit; system approach; sustainable energy systems; Environmental engineering; Miljöteknik;

    Abstract : This thesis analyses a specific type of energy usage system, “energy usage in hotels”, and how this system behaves. In order to evaluate the current state of energy use in hotels, an energy audit questionnaire was developed and conducted among 31,5% of hotels on the Adriatic coast. READ MORE

  7. 20. Lighting Control Systems for Energy Saving and User Acceptance: State-of-the-art and future directions

    Author : Niko Gentile; Institutionen för arkitektur och byggd miljö; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Indoor lighting; lighting control system; lighting control; energy saving; energy efficiency; user acceptance; human factor; occupancy strategies; absence sensor; presence sensor; lighting switch; manual switch; daylight harvesting system; daylight-linked system; photoelectric dimming; photosensor.;

    Abstract : Lighting accounts for one-fifth of global electricity use. In Sweden, energy demand for lighting corresponds to 20% of the total electricity use in office buildings. Lighting retrofit measures are considered to be among the most cost-efficient way to reduce energy use in buildings. READ MORE
