  2. 16. Modelling Towards Control of Dynamic Systems : Applications on RDF Fired CFB Performance and DHN Distribution

    Author : Nathan Zimmerman; Konstantinos Kyprianidis; Carl-Fredrik Lindberg; Erik Dahlquist; Natasa Nord; Mälardalens universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Heat and Power; Circulating Fluidized Bed Boiler; District Heating; Model Predictive Control; Feed-Forward; CHP; Energy- and Environmental Engineering; energi- och miljöteknik;

    Abstract : The combination of global warming along with increasing energy demand necessitates the importance of improving processes pertaining to the production and consumption of energy in combined heat and power plants. This thesis brings to light transient factors currently burdening process performance for circulating fluidized bed boilers (CFBs) combusting refuse derived fuels (RDFs) and district heating networks (DHN).

  4. 17. Modelling the dynamics of domestic low-temperature heat pump heating systems for improved performance and thermal comfort : a systems approach

    Author : Dimitra Sakellari; Per Lundqvist; Savvas Tassou; KTH; []
    Keywords : Technology; heat pump; domestic heating and ventilation; low-temperature hydronic heat distribution; systems approach; integration; simulation; energy efficiency; TEKNIKVETENSKAP; TECHNOLOGY; TEKNIKVETENSKAP;

    Abstract : The present environmental concerns and the rising human requirement for solutions with better comfort and lower costs have resulted in an increased awareness for the energy use in the built environment. Technical advances in building structural systems and materials, heating and other comfort-providing systems and controlling strategies all lead to the integration of building technology with the function of buildings and the aesthetics.

  5. 18. Distribution and Differences : Stratification and the System of Reproduction in a Swedish Peasant Community 1620-1820

    Author : Jonas Lindström; Maria Ågren; Jan Lindegren; Carl-Johan Gadd; Uppsala universitet; []
    Keywords : HUMANIORA; HUMANITIES; Peasant; stratification; inequality; reproduction; resources; distribution; social mobility; household; family; community; landholding; principles; conditions; social structure; feudalism; early modern period; Björskog; Sweden; agrarian history; social history; History; Historia;

    Abstract : This dissertation examines the character, conditions and change of peasant stratification in early modern Sweden. Wherever and whenever one looks, one finds that resources were unevenly spread among peasant households. In the literature, there are different, and conflicting, views compatible with this finding.

  7. 20. Residential Demand Response in the Context of European Union Energy Policy

    Author : Pia Stoll; Fredrik Gröndahl; Nils Brandt; Lars Nordström; Will Kling; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Industrial Ecology; Industriell ekologi;

    Abstract : In order to achieve energy security, reduce global warming and promote the vision of a common electricity market, the European Union (EU) is transforming the EU electricity grid from a large set of independent hierarchical national grids into one meshed EU-wide grid. For the first time in the history of the electric power industry, residential consumers are being integrated into the grid as active consumers and micro-generators of electricity. READ MORE
