This report summarizes the work carried out in Sub-Task 1(a), Systems Studies and Optimization, of Task VII, Central Solar Heating Plants with Seasonal Storage (CSHFSS), of the IEA Solar Heating and Cooling Program.

The objectives of Sub-Task 1(a) were:

• to develop procedures and analytic tools for studying system feasibility and for evaluation, and

e to recommend specific systems analysis procedures and tools for use in Sub-Task 1(e), Site-Specific Preliminary Design, and Phase IX of Task VII.

As outlined in this report, the approach adopted for Sub-Task 1(a) was to select, modify and further develop two analytic tools as design aids for CSHPSS and to examine the appropriateness of these tools by undertaking application case studies. Although the CSHPSS configurations were limited by the lack of complete flexibility of the design tools, applications over a range of system sizes, collector types, weather conditions and operational schemes can be examined. It was concluded that the MINSUN program, in particular, was a useful tool for understanding the thermal and economic characteristics of many CSHPSS configurations and over a broad size range.

About the work with MINSUN until now, the following remarks can be made:

• to do with MINSUN the optimization work on a system several assumptions have to be made to model the system with MINSUN,

• to make these assumptions it is necessary to have the results (energy flows in the system) of a simulation programme (TRNSYS/TNO-model),

• the energy savings of a certain system is strongly dependent on the location (solar insolation/heat load),

• fuel price and system component cost have a large influence on the annual cost. For an optimization study it is necessary to have reliable cost data.
