Solar-energy-system performance evaluation: final report for Honeywell OTS 44, Ocmulgee, Georgia

Technical Report ·
OSTI ID:6890139
The operation and technical performance of the Solar Operational Test Site (OTS 44) at Ocmulgee National Monument, in Georgia, are described, based on the analysis of data collected between April 1981 and August, 1981. The following topics are discussed: system description, performance assessment, operating energy, energy savings, system maintenance, and conclusions. The solar energy system at OTS 44 is a hydronic heating and cooling system consisting of 5040 square feet of liquid-cooled flat-plate collectors; a 4000-gallon thermal storage tank; one 25-ton capacity organic Rankine-cycle-engine-assisted water chillers; a forced-draft cooling tower; and associated piping, pumps, valves, controls and heat rejection equipment. The solar system has eight basic modes of operation and several combination modes for providing space conditioning and hot water to the building. Based on the instrumented test data monitored and collected during the 4 months of the Operational Test Period, the solar system collected 285 MMBtu of thermal energy of the total incident solar energy of 1040 MMBtu and provided 210 MMBtu for cooling and 10 MMBtu for heating and hot water. The net electrical energy saving due to the solar system was approximately 2600 kWh(e), and fossil energy saving was about 20 million Btu (MMBtu).
