TEMPORAERE THERMISCHE ISOLIERUNG BEI DER PASSIVEN SOLARNUTZUNG - ENTWICKLUNG EINES WAERMESCHUTZROLLADENS.
A super insulating rolladen is developed, which gives an effective temporary thermal insulation (night insulation) for passive solar utilisation. The k-value of the thermal insulation device + in connection with a double glazing + is about 0.5 W/m**2K, which is the insulation of a very well insulated wall. In order to present a most cost effective design, our research has focused on a concept, using standard rolladen components to a large extent. The work programme covered conceptual work, set up of a testing + and proving stand, performance of heat transfer measurements and initiation of life tests and proving programme. The design work took account of the structure to withstand influences like storm, hale, dust, rain, solar radiation, and mechanical strains. Other design criteria were low maintenance costs, long life time, good architectural integration of the rolled up device and easiness of operation. A prototype series of rolladen elements have been produced for the thermal and mechanical tests. The thermal effectiveness of the rolladen and the mechanical stability have reached the design goal. The work has shown, that the boundary effects are of great importance on the overall performance. Several guidance and sealing techniques have been tested, which keep the losses by air infiltration and thermal conductivity low. Future work has to cover the large scale production aspects, the broadening of the range of technical adaptability, improving thermal testing, and architectural integration."
