Solar project description for Loudoun County Vocational Technical Education Center

Technical Report ·
OSTI ID:5496217

The solar energy system for the Loudoun County School in Leesburg, Virginia, provides solar preheating of the domestic hot water supply for the Charles S. Monroe Vocational-Technical School. The system utilizes 34 Southwest Ener-Tech collectors with a total gross area of 1225 square feet. The collectors face 15/sup 0/ west of south at a tilt angle of 37/sup 0/ from the horizontal. The collectors are ground mounted in one bank in a courtyard surrounded by a brick wall on the north side of the building. The collectors are piped in parallel with one absorber plate and two framed glazings per collector. A solution of Silicone-based oil is used as the heat transfer medium. The working fluid is heated by the collectors and circulated through a heat exchanger in the 2056 gallon solar storage tank. The preheated water from the solar storage tank is then supplied on demand to a smaller (1000 gallon) storage tank. Additional heat is supplied, if required, by an auxiliary electrical heating element in the smaller storage tank. (MHR)
