1. Calculation and Measurement Methods for the Performance of Solar Collectors. Models of Flat Plate Collectors, Transparent Insulation and Efficiency Factors
Sammanfattning : This thesis deals with models of flat plate collectors, transparent insulation and efficiency factors. An equation for the energy output from a glazed flat plate collector is derived by modelling the collector efficiency factor, F´ as the sum of a constant and a temperature dependent part. LÄS MER
2. Characterising Resistance to Electrical Treeing in New XLPE-Based Materials for High-Voltage Cables
Sammanfattning : This work looks into electrical treeing in cross-linked polyethylene-based materials (XLPE), where the ability to resist tree development is considered as an indicator of improved applicability for insulation in high voltage power cables. The thesis presents results of a twin PhD project involving joint work of two students. LÄS MER
3. Optical design of stationary solar concentrators for high latitudes
Sammanfattning : The optical design of stationary solar concentrators for high latitudes has beenstudied. Irradiation distribution diagrams, which are tools for the design ofstationary linear concentrators, have been developed. LÄS MER
4. Solar Thermal Collectors at High Latitudes : Design and performance of non-tracking concentrators
Sammanfattning : Solar thermal collectors at high latitudes have been studied, with emphasis on concentrating collectors. A novel design of concentrating collector, the Maximum Reflector Collector (MaReCo), especially designed for high latitudes, has been investigated optically and thermally. LÄS MER
5. Single Skin Glazed Office Buildings - Energy Use and Indoor Climate Simulations
Sammanfattning : Modern office buildings have high energy savings potential and potential for indoor climate improvements. During the nineties many office buildings with glass facades were built, in several cases with double skin glass facades. LÄS MER
