  1. 1. Solar Heating with Seasonal Storage. Some Aspects of the Design and Evaluation of Systems with Water Storage

    Author : Jan-Olof Dalenbäck; Chalmers University of Technology; []
    Keywords : solar heating; water storage; solar power; simulation;

    Abstract : The report provides a basis for detailed design and evaluation of future solar heating plants with an insulated seasonal water storage. The importance of careful design and plant commissioning is pointed out and a system simulation model for future analyses of system performance is provided. A general evaluation methodology is presented. READ MORE

    Abstract : Energy from solar photovoltaic (PV) are generated as direct current (DC) and almost all of today’s electrical loads in residential buildings, household appliances and HVAC system (Heating Ventilation and Air-conditioning) are operated on DC. For a conventional alternating current (AC) distribution system this requires the need for multiple conversion steps before the final user-stage. READ MORE

  4. 4. Characterization of Chimney Flue Gas Flows : Flow Rate Measurements with Averaging Pitot Probes

    Author : Janne Paavilainen; Chris Bales; Jan-Olof Dalenbäck; Lennart Gustavsson; Högskolan Dalarna; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Flue gas; measurement; characterization; averaging Pitot tube; SolNET;

    Abstract : Performance testing methods of boilers in transient operating conditions (start, stop and combustion power modulation sequences) need the combustion rate quantified to allow for the emissions to be quantified. One way of quantifying the combustion rate of a boiler during transient operating conditions is by measuring the flue gas flow rate. READ MORE

  5. 5. Energy Efficiency in Shopping Malls : Some Aspects Based on a Case Study

    Author : Sofia Stensson; Jan-Olof Dalenbäck; Per Fahlén; Monica Axell; Jeffrey Spitler; Sweden Chalmers University of Technology; []
