Through the use of central solar heating plants with large, seasonal storage
systems, solar energy can be collected during the summer and stored until needed
in the heating season when solar radiation is often insufficient. As a result of
the Task 7 collaboration, significant advances were made in this technology.
During the first phase, participants collected engineering, performance and cost
data on the major component subsytems. A parallel effort involved the
development of MINSUN, a simulation and optimization program for central solar
In the second phase, MINSUN was used to make a systematic evaluation of various
design concepts and to identify thise which appeared to be modt promising.
During phase III, participants exchanged data on the design, construction and
operation of existing or new CSHPSS systems and jointly evaluated this
