Influence of solar field recirculation on medium-size CSP performance

The results of this study show that partial recirculation of the solar field does not allow performance improvement of the CSP plant. Moreover, bypassing the cold tank in the recirculation path avoids a strong deterioration in performance. Differences between recirculation strategies become subtler for clear-sky days and, therefore, the present results can be very useful for improving the CSP performance, especially during mostly cloudy days.
