Resumo(s)
This paper presents first results of a project that aims at the development of new mathematical models for characterization of Solar Thermal Systems (Factory Made Systems as defined in EN 12976) that can be used in association with dynamic system testing (non intrusive test method defined in the document ISO 9459-5) and which, based on the characteristic parameters defined in the adopted models, allow determination of those parameters by fitting between real test sequences and test sequences produced by the developed models, using fitting techniques independent of the models chosen for system characterization.
Another important goal of the project is the validation of results for Long Term (thermal) Performance (LTP) of the solar systems, based on the models developed, by comparison with long term measurement sequences obtained by the monitoring of different system types. Installation of the testing facility for this purpose is also described in the present paper.
