    Sammanfattning : Nonlinear systems occur in industrial processes, economical systems, biotechnology and in many other areas. The thesis treats methods for system identification and control of such nonlinear systems, and applies the proposed methods to a solar heating/cooling plant. LÄS MER

  3. 12. Load Adapted Solar Thermal Combisystems - Optical Analysis and Systems Optimization

    Författare :Svante Nordlander; Högskolan Dalarna; []
    Nyckelord :Solar Combisystems Concentrating Collector Optimization Incidence Angle Optical Efficiency Simulation TRNSYS Stagnation;

    Sammanfattning : In a northern European climate a typical solar combisystem for a single family house normally saves between 10 and 30 % of the auxiliary energy needed for space heating and domestic water heating. It is considered uneconomical to dimension systems for higher energy savings. Overheating problems may also occur. LÄS MER

  4. 13. Studies on the adsorption of flotation collectors on iron oxides

    Författare :Elisaveta Potapova; Luleå tekniska universitet; []
