ADVANCED STORAGE CONCEPTS FOR ACTIVE SOLAR ENERGY IEA-SHC Task 32 2003-2007

摘要

Storage is a key success factor for the large development of solar heat utilisation in mid climate. IEA Solar Heating Cooling Programme started Task 32 in 2003. After 4,5 years Task 32 was completed in December 2007. The main objective of the Task was to contribute to the development of advanced storage solutions in thermal solar systems for buildings that lead to high solar fraction, and up to 100% in a typical 45N latitude climate. The Task was organised in 4 Subtasks: 1. Subtask A: Evaluation and Dissemination (Subtask Leader: Switzerland/France Thomas Letz) 2. Subtask B: Chemical and Sorption (Subtask Leader: Chris Bales, Sweden) 3. Subtask C: Phase Change Materials (Subtask Leader: Wolfgang Streicher, Austria) 4. Subtask D: Water (Subtask Leader: Harald Drueck, Germany) and gave valuable results and new information in all aspects of the 4 technologies that were investigated. This paper by the Operating Agent presents an overview of achievements and some of the main results. For detailed presentations of the scientific work, the reader can refer to companion papers from experts who participated in Task 32 and to the http://www.iea-shc.org/web site.
