Simulation and Optimization Report - Maxlean Concept
March 2008 - PDF 2.25MB
This report is part of Subtask D of the Task 32 of the Solar Heating and Cooling Programme of the International Energy Agency dealing with solutions of storage based on water. Water tank storage is still the state-of-the-art way to store solar energy between 20 and 100C. There is however some potential for further improvements of storage in water tanks and of combisystems with water tank storage. 71 pages

Experiments with Vertical Plates for Temperature Stratification in a Heat Storage Tank
Report D2 of Subtask D
October 2007 - PDF 0.37MB
Experiments were carried out to test an inexpensive set-up to enhance temperature stratification in water heat stores or water heater stores. The set-up essentially consists of an arrangement of two vertical parallel plates open to the storage volume on all or most sides with the inlet flow entering the gap between the plates through a flange on one of them. Any difference in temperature or density between the entering flow and the fluid in the store will allow it to propagate vertically between the plates in reaction to the differing buoyancy of the respective fluids. 18 pages
