Abstract
A methodology for solar energy system design improvement has been developed and coupled with a constrained function optimization code resulting in an automated solar energy system design procedure. The scope of the methodology is limited to systems using flat plate collectors and water as the working fluid. Eight parameters have been included as independent design variables. The design variables included collector area, collector tile angle, collector and storage fluid stream velocities, and collector to storage heat exchanger dimensions. The procedure includes an accounting for economic parameters as an intimate part of the design process. The resulting methodology has been used for the design of solar energy systems which would use shelf item collectors for the purposes of determining the optimum design variable vector for a given situation. The methodology could also be used on a limited basis for collector design optimization by exploring the effects of changing selected collector parameters on system performance. The methodology is coded in the FORTRAN computer language under the name SOLCAD-1 (SOLAR ENERGY OPTIMIZATION ANALYSIS OR DESIGN). Initial system trials indicate complete stability with minimal constraint activations. Eased on the results of approximately fifty design experiments using SOLDAD-1, new findings concerning optimum collector tilt angle and an invariant optimum collector flow factor are suggested.
