Method and Comparison of Advanced Storage Concepts
Report A4 of Subtask A
December 2007 - PDF 0.3MB
This report presents the criteria that Task 32 has used to evaluate and compare several storage concepts part of a solar combisystem and a comparison of storage solutions in a system. Criteria have been selected based on relevance and simplicity. When values can not be assessed for storage techniques to new to be fully developed, we used more qualitative data. 29 pages

Performances of Solar Combisystems with Advanced Storage Concepts
Report A3 of Subtask A
December 2007 - PDF 0.59MB
Editor: Thomas Letz
In the present report, simulation results for nine different systems are presented: five for systems using water storages, one for a system using a storage with Phase Change Material (PCM), and three for systems using chemical or sorption storages. Curves have been drawn for two indicators: the thermal end the extended Fractional energy savings. These characteristic curves allow seeing at one glance how a system performs. They are similar to the characteristic curves of solar collectors, which allow visualising the performances of different concepts. 46 pages

The Extended FSC Procedure for Larger Storage Sizes
Report A1 of Subtask A
December 2007 - PDF 0.43MB
Editor: Thomas Letz
In task 26 "Solar Combisystems", a new characterization method had been proposed, allowing to summarize the behaviour of a whole combisystem with a simple parabolic equation giving the thermal or extended fractional energy savings according to a new parameter called Fraction Solar Consumption (FSC). 19 pages

The Reference Heating System, the Template Solar System of Task 32
Report A2 of Subtask A
May 2007 - PDF 0.54MB
This work defines reference conditions and a reference simulation environment for the simulation of solar combisystems for domestic hot water (DHW) preparation and space heating (SH) for various European climates and a range of building loads. These will be used for simulation studies within the IEA-SHC Task 32 by all participants who intend to compare their new products or ideas with the current state of the art or with other products and system approaches. 55 pages.
