South Dakota School of Mines, Keystone, South Dakota: solar energy system performance evaluation, December 1979-May 1980
Performance of the South Dakota School of Mines solar energy system from December 1979 to May 1980 is described. The system is installed in the Mt. Rushmore National Memorial Visitors' Center near Keystone, South Dakota. The site is located at 44/sup 0/N latitude and 1600 m elevation. The building has 540 m/sup 2/ of conditioned space and a design overall thermal transfer coefficient (UA) of 0.22 GJ(/sup 0/C/sub <21/ d)/sup -1/. The solar energy system is of liquid-based active type, with 187 m/sup 2/ of flat-plate collector area and 11.4 m/sup 3/ of water thermal storage. The site experienced average irradiance of 155 WM/sup -2/ and average ambient temperature of 2/sup 0/C during the period described. Under these conditions, the solar energy system supplied 43% of the energy required for space heating, saving 3790 liters of fuel oil that would otherwise have been burned. Storage temperature set points for energy supply to space heating were investigated during the season, and results of the investigation are described. The regime of 38/sup 0/C threshold and 32/sup 0/C cutoff temperature was found to be optimal.
