Embodiment Construction
[0026] The present invention will be further described below in conjunction with the embodiments shown in the accompanying drawings.
[0027] The present invention proposes a solar thermal photoelectric frequency division utilization system based on a reflective Fresnel concentrator, figure 1 A schematic diagram of the optical path of the system, figure 2 A schematic diagram of the waterway of the system. The system includes a direction control unit, a preheating unit, a photoelectric unit, a photothermal unit, a concentrating unit and a heat recovery unit. The photothermal unit absorbs the thermal energy of sunlight; the photoelectric unit performs photoelectric conversion of sunlight; the preheating unit recycles the heat generated by the photoelectric unit; the concentrating unit gathers sunlight; the heat recovery unit recycles the heat absorbed by the photothermal unit; The direction control unit connects the photoelectric unit, the photothermal unit and the light conc...
