Resumen o descripción
The methodology and results of the thermal and hydraulic design for a solar heating field of an elementary school’s semi-olympic is presented. Improved flat solar collectors with copper tube and aluminum fins, were used.
From own experiences, many Mexican solar fields does not operate correctly because of their poor irrigation, may be due to lack of attention given to this aspect. That's why the research of this work focuses on studying the behavior of the pressure drop in a hydraulic arrangement, particularly of this facility, in which all collector batteries are connected in parallel.
Previously two solar heaters were sent to a specialized laboratory for certification tests, obtaining the optimum water flow value for maximum thermal efficiency. The results show an optimum range between 4 and 11 L/min.
On the other hand, the develop of a thermal model based on a temporal energy balance, allowed us to determine that the optimum solar heating area is about 338 m2, using 195 flat-coated solar heaters, copper tube and aluminum fin.
For this heating system a volume water/solar collection, called REVA, of 1.45 m3/m2 was obtained. Referred to the hydraulic design and using the program EPANET 2.0 was found that in the proposed arrangement, 192 solar heaters were irrigated with the optimal range and only 2 solar collectors were below the lower range at 3 L/min
