  2. 1. The Compression/Absorption Heat Pump Cycle - System Simulations

    Author : Lena Åhlby; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; compression; refrigerant mixture; absorption; NH3 H2O; NH3 H2O-LiBr;

    Abstract : From the results presented in this thesis it is clear that the compression/absorption heat pump cycle offers several advantages over other types of heat pumps. In many cases it gives a higher or equally high COP compared with the single-fluid compression heat pump but also the smaller SCD (i.e. READ MORE

  5. 3. Lifecycle of Black Carbon in the Arctic

    Author : Roxana S. Cremer; Ilona Riipinen; Peter Tunved; Sara Blichner; Hannele Korhonen; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Black Carbon; Aerosols; Arctic; lifecyle; absorption; Environmental Sciences; miljövetenskap;

    Abstract : This PhD thesis investigates the atmospheric life cycle of Black Carbon (BC) in the Arctic. The Arctic region has been rapidly changing in the last decades and the role of BC aerosols in this is still uncertain. READ MORE

  6. 4. On the Arctic Seasonal Cycle

    Author : Jonas Mortin; Gunilla Svensson; Rune G. Graversen; Wolfgang Dierking; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Arctic climate; Seasonal melt-freeze transitions; Arctic sea ice and snow; Active microwave measurements; Climate model evaluation; atmosfärvetenskap och oceanografi; Atmospheric Sciences and Oceanography;

    Abstract : The seasonal cycle of snow and sea ice is a fundamental feature of the Arctic climate system. In the Northern Hemisphere, about 55 million km2 of sea ice and snow undergo complete melt and freeze processes every year. READ MORE

  7. 5. Combined Electricity Production and Thermally Driven Cooling from Municipal Solid Waste

    Author : Seksan Udomsri; Andrew R. Martin; Torsten Fransson; Erik Dahlquist; KTH; []
