Abstract
In the specific chapter, the optical performance of a symmetric and an asymmetric mini compound parabolic concentrator, adjusted on a circular absorber, is investigated. The operation of the two concentrators was examined at the typical day of each month of a whole year in Athens, considering that the north-south axis is first parallel to the width of the reflectors (E-W axis orientation) and then to the length of them (N-S axis orientation). The collectors’ performances were examined at 9 h of each day from 8:00 to 16:00. The symmetric configuration was tested not only at horizontal position but also by setting its aperture plane parallel to the aperture of the asymmetric reflector (7° inclination) for the E-W axis orientation. The results showed a total prevalence of the asymmetric configuration in the majority of the examined cases greater than 4.7%. The design and simulation of the concentrators were conducted in Solidworks.
