The following is the design, construction and testing of the prototype of a high
temperature solar thermal concentrator type PDR (parabolic disc reflector). For
this purpose it is required that at its focus reach at least a temperature of 700 °
C, which is enough to be considered as a high temperature and additional
concentrator, manufactured with low cost materials.
Based on its operating principle of a PDR solar disk, the incidence of solar
radiation in the department of Boyacá, located in the central region of Colombia,
is explained, has good potential, compared to other latitudes of the planet, as
well as the necessary considerations in radiation losses by atmospheric
diffraction due to the typical climatic conditions of the area. The prototype is
designed, looking for its manufacture to allow imperfections in the geometry to
be minimal, as well as the materials used for its development. A solar
concentrator with an aperture of 1500mm and a focal point height of 900mm
has been chosen. We proceed to the construction of the prototype at scale,
which is evaluated through tests and applied techniques, such as irradiation,
heat transfer that occurs in the focus, among other measurements that are
made, obtaining the collection of data. The evaluation and discussion of the
results is carried out to issue concepts regarding the operation of the PDR solar
concentrator, for high power generation and manufactured with low cost
materials. The results will be compared with those obtained in studies from
other countries using the same design criteria, but with different solar radiation
and different materials. In this way it contributes with the research for the use
of alternative energies of low cost, of easy acquisition.
