На английском языке. A report within IEA Heating and Cooling Program – Task 7, 1982, 107 pages.
In reality it was not possible to follow the original straightforward plan of work, in which the collection of a design basis was to be followed by a preliminary design, which eventually was
leading to a detailed design. It was found that the R & D on the fundamental major parts of a solar heating system with seasonal storage was still in a very dynamic phase and not yet yielding definitive conclusions and design recommendations. The subtask of bringing the design basis together and documenting it for future use became part of the proper R & D efforts in the
participating countries. This had the effect that the preliminary designs in most cases were not directly based on the final reports from subtasks 1(a) - 1(d), but on the knowledge and
experience that was available within each of the countries at the time. The work on Task VII had of course contributed to this knowledge, but it is impossible to say to what extent.
This report is a summary documentation of the preliminary designs from the 10 participating countries, more detailed information being available in national reports. The documentation
follows a format, which was developed by the participants as an adaption of the IEA reporting format for thermal performance of solar heating and cooling systems in buildings (from
Task I).
A development of the original plans for the Task is the fact that some countries actually built systems for solar heating with seasonal storage already during the first Phase of Task VII. In those cases the documentation covers these systems and has a greater realism than originally anticipated.
This report will present an overview of the national designs. First, however, an overview of the total work on Task VII will be given.
