The Page Jackson Elementary School in Charles Town, West Virginia has a solar energy system for space heating and cooling for the 52,600 square foot building. The 11,215 square feet of PPG double-glazed, flat-plate collectors face south at a 45/sup 0/ angle to the horizontal. The collectors are piped in reverse return with insulated copper branch piping. The collectors are attached to the sawtooth framing and glass mirrors are attached to the north side of the frame. Copper absorber plates, with a black chrome selective coating, are soldered to copper tubing. The two 1/8 inch Herculite tempered glass glazings are separated from each other and the absorber plate by 3/8 inch airspaces. There is a 6 inch fiberglass insulating batt placed behind the uninsulated collectors. Overheat protection is provided by circulating storage water. Freeze protection is provided daily by automatically draining the collectors and the exterior piping after the collector pump turns off. Two insulated 10,000 gallon steel storage tanks are located in the mechanical equipment room and are connected in series. The tanks are insulated with 6 inches of sprayed urethane insulation which has an asbestos coating. No chilled water storage is provided. Space heating is provided by circulating warm storage water through five air handling units. A 780,000 Btu/hr oil-fired boiler is used for additional heating. Space cooling is provided by pumping hot storage water to a 100-ton absorption chiller. (MHR)
