Resumen
The design of two collectors based on SunDial technology is conducted for two distinct case studies: a dairy company situated in Corinth (latitude 37.9 ◦N) and a steel company located in Iasi (47.1◦N). The discrepancy in latitudes necessitates different concept designs, one-axis for the former and two-axis tracking for the latter.
To develop these collectors, a combination of models is employed, including a thermal model for the receiver, an analytic model for predicting mirror shape, an analytical model for reducing the number of optical design variables, and a Monte Carlo Ray Tracing model for final field optimization. The optimization results in both case studies indicate the adoption of double-field configurations, involving a rotary platform with two fields on top. Notably, for higher latitudes, the size of the platform and the total reflecting surface are smaller compared to lower latitudes (8.3 × 8.3 m2 Vs. 8.0 × 8.0 m2 and 47 m2 Vs. 44 m2, respectively). These compact collectors lead to an annual energy yield of 27.8 MW h at their respective final locations.
