1. Gas-filled, flat plate solar collectors
Abstract : This work treats the thermal and mechanical performances of gas-filled, flat plate solar collectors in order to achieve a better performance than that of air filled collectors. The gases examined are argon, krypton and xenon which all have lower thermal conductivity than air. The absorber is formed as a tray connected to the glass. READ MORE

3. Calculation and Measurement Methods for the Performance of Solar Collectors. Models of Flat Plate Collectors, Transparent Insulation and Efficiency Factors
Abstract : 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. READ MORE

4. Retrofitted Solar Domestic Hot Water System for Single-Family Electrically-Heated Houses: Development and testing
Abstract : In Sweden, there are roughly half a million single family houses that use electric heating for both domestic hot water production and space heating. Since electricity is the most expensive energy source in Sweden, it is interesting to install a high solar fraction solar thermal system to reduce the energy use in these houses. READ MORE

5. Load Adapted Solar Thermal Combisystems - Optical Analysis and Systems Optimization
Abstract : 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. READ MORE
