  2. 6. Solar-driven refrigeration systems with focus on the ejector cycle

    Author : Wimolsiri Pridasawas; Per Lundqvist; Hans-Martin Henning; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Solar Cooling; Solar-Driven Refrigeration System; Ejector; Ejector Refrigeration Cycle; Exergy Analysis; Dynamic Analysis; Engineering mechanics; Teknisk mekanik;

    Abstract : Interest in utilizing solar-driven refrigeration systems for air-conditioning or refrigeration purposes has grown continuously. Solar cooling is com-prised of many attractive features and is one path towards a more sus-tainable energy system. READ MORE

  4. 7. How will climate change working life?

    Author : Karin Lundgren Kownacki; Ergonomi och aerosolteknologi; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; occupational heat stress; climate change; productivity; international standards; India;

    Abstract : Heat stress has been studied extensively. However, in the contemporary context of climate change there is a lack of information on the extent of future heat stress and its consequences, especially in occupational settings. READ MORE

  5. 8. Applications of Finite Element Simulation and Mixed Reality in Architecture and Built Environment

    Author : Carl Lundholm; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; augmented reality; FEniCS; multimesh; CutFEM; multi-objective optimization; mixed reality; HoloLens; virtual reality; view computation; finite element method;

    Abstract : This thesis presents applications in architecture and built environment that are based on the finite element method and mixed reality. The work consists of two main components: two projects presented in three papers. The first project (presented in Paper I) concerns an application in urban design, thus built environment on a larger scale. READ MORE

  6. 9. State-of-the-art Integrated Refrigeration Systems in Supermarkets : An Energy Efficiency Evaluation Based on Field Measurements Analysis and Computer Simulations

    Author : Mazyar Karampour; Samer Sawalha; Björn Palm; Silvia Minetto; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Carbon dioxide CO2 ; Supermarket; Supermarket refrigeration; Trans-critical cycle; Field meas-urements; Computer simulation; System integration; State-of-the-art; Heat recovery; Air condi-tioning; Reference HFC system; Geothermal energy storage; Energiteknik; Energy Technology;

    Abstract : Supermarkets have become a vital feature of modern society. However, they have significant impact on the environment due to the large amount of refrigerants needed in the refrigeration system, and due to the large energy use in the supermarket, they are the commercial buildings with highest energy intensity.
