Definitions
- This invention relates to solar energy technology and, in particular, to the testing of materials and articles for resistance to solar light and weather factors with the use of concentrated solar radiation.
- the rate of these and other degradation processes depends on the composition of the atmosphere, temperature, and exposition to light.
- the exposition to light irradiation is most pronounced in the ultraviolet (UN) region of solar spectrum (290 -450 nm).
- the physical nature of the predominant effect of UN radiation of the Sun in material degradation processes is caused by the fact that the energy of photons of solar light in this part of spectrum corresponds to the energies of rupture of typical chemical bonds of organic and organoelernent compounds (C-C; C ⁇ ; C-O; C-"F; C-Cl, and etc;).
- Irradiation of materials with the light of the long-wave (visible and infrared) regions of solar spectrum is responsible only for the heating of materials.
- this concentrator is also characterized by complex Sun tracking and impossibility of obtaining high solar concentration ratios.
- the invention allows the achievement of required result which consists in a reduction of a time period necessary for testing the objects by a factor of up to 100 (several days instead of several months or years) with highly reliable predictability of behavior of objects under a wide variety of testing conditions due to creation of concentrated, uniform, and selective with respect to spectrum light spot in a plane wherein the samples under tests are arranged.
- a multi-face concentrator of a solar setup for exposure of objects placed in a target plane to the action of solar radiation which comprises a supporting frame and facets differing by that the facets of the concentrator are chosen with spherical focusing reflective surfaces of equal focal lengths and with selective coatings reflecting a desired spectral fraction of solar radiation, and are arranged on the supporting frame symmetrically with respect to the common axis of the concentrator, their optical axes being directed to the single point on the optical axis of the concentrator located before the nominal focus point of the concentrator and determining the position of arranging the target plane.
- Figure 1 shows the block diagram demonstrating the formation of uniform flux irradiating, the samples in the target plane.
- Figure 2 shows the optical scheme demonstrating the formation of uniform flux irradiating the samples in the target plane.
- Figure 3 shows the photo of the experimental setup with the multi-facet selective concentrator intended for accelerated natural sunlight weathering of materials.
- Figure 4 demonstrates experimental data on reflective characteristics of the concentrator facets.
- Figure 5 demonstrates experimental data on distribution of flux power over a target area.
- the concentrator contains a carrying frame 1, whereon facets 2, such as a K-8 5 grade glass substrate, are placed symmetrically with respect to the common optical axis. In this case, the optical axes of the facets are directed to a common point 3 located on an optical axis of the concentrator and disposed before nominal focal point 4 of the concentrator.
- the position of target plane 5, where the common area 6 is located being determined by point 3.
- the common point 3 is disposed before the nominal focal point 4, to achieve less than maximal concentration, and at a fraction of the nominal facet focal length 7 so as to retain an image with approximately the same shape as the facet 2, but with smaller size in proportion to the ratio of distance 3 to distance 4.
- This aiming strategy and concentrator design provides a means to vary the concentration by changing the distance of common point 3 without any changes to the concentrator except reaming the facets. It is the overlapping of essentially equal and uniform facet images that create the uniform flux intensity on the object to be exposed.
- the concentrator operates in a following mode.
- the incident radiation corresponding to whole solar spectrum comes to facets 2 having selective reflective coatings with predetermined characteristics.
- the fraction of radiation reflected from facets 2 with selective coating is directed to target plane 5.
- all the facets are adjusted so that the light spot with high uniformity degree of illumination is collected onto a common area 6 (Fig. 2) in a target plane 5.
- Fig. 2 a common area 6
- Example 1 Example 1
- Figure 3 shows the photo of the experimental setup with the multi-facet selective concentrator intended for accelerated natural sunlight weathering of materials.
- Figures 4 and 5 demonstrate experimental data on reflective characteristics of the concentrator facets and distribution of flux power over a target area, respectively.
- the present invention can be also effectively used in a series of other applications such as the part of solar setups for waste waters detoxification, disinfecting and purification of water, laser pumping with natural sunlight radiation, targeted photo and photocatalytic synthesis of chemicals using sunlight energy, and photovoltaic power systems using concentrated solar radiation.
