Comparison of Multitank Storage DHW Heating Solar Plants.[CONFRONTO FRA IMPIANTI SOLARI CON ACCUMULO A SERBATOIO MULTIPLO.]

Distribution of the hot storage in a multitank system may be a suitable way to assure stratification in DHW solar heating plants of medium and great sizes. The possible connections for the various tanks are manifold: three different working ways are considered in this paper. Performances are analyzed during one year through TRNSYS computing program and the results are compared
