  2. 6. Seasonal snow storage for cooling applications

    Author : Kjell Skogsberg; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Vattenteknik; Water Resources Engineering;

    Abstract : Seasonal snow storage for cooling applications is an ancient technique now being revived in different parts of the world. From June 2000 the first Swedish large-scale snow cooling plant provides for comfort cooling at the hospital in Sundsvall. The snow is thermally insulated by a 0. READ MORE

  4. 7. Impact of climate variability on dynamic groundwater storage in mid- to high latitude countries

    Author : Michelle Nygren; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; climate change; time series analysis; groundwater statistics; Sweden; drought; cold region hydrogeology; groundwater memory;

    Abstract : Climate change will alter the hydrological cycle, potentially changing dynamic groundwater storage and increasing groundwater drought risk. Climate influences groundwater storage directly via changes in groundwater recharge, but groundwater drought responsiveness further depends on groundwater system characteristics. READ MORE

  5. 8. A systems approach to ice loads on concrete dams

    Author : Rikard Hellgren; Richard Malm; Anders Ansell; Erik Nordström; Pierre Legér; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Ice loads; Ice pressure; Dam safety; Concrete dams; Cold regions; Monitoring; Measurements; Concrete Structures; Betongbyggnad;

    Abstract : Dams are mainly used for the storage of water to electricity production and irrigation, or for river regulation. Continuous work to assure a high dam safety level is a prerequisite to minimize the risk for the uncontrolled release of water. READ MORE

  6. 9. Short term water heat storage : an experimental and numerical investigation of phenomena that affect the degree of thermal stratification

    Author : Roger Hermansson; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energy Engineering; Energiteknik;

    Abstract : Thermal stratification was studied by measurements of the temperature and velocity fields in water heat storage's and by numerical simulations. The work includes experimental investigations in three model heat storage's of different size and comparisons to numerical simulations for two of the storages. READ MORE

  7. 10. Identification of risk factors in cold work

    Author : Lina Giedraityte; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Industrial Work Environment; Industriell produktionsmiljö;

    Abstract : All employers and self employed people have a legal duty to assess risks from their work activities, and for many persons in various occupations cold is a source of risks to their health and well-being. Questionnaire surveys conducted in the Nordic countries have indicated that 14 - 16% of employees experience cold as a hazard in their work. READ MORE
