Fresnel/Photovoltaic Concentrator Application Experiment for the Dallas-Fort Worth Airport. Phase 1: System Design, Final Technical Report, 1 June 1978-28 February 1979

摘要

This Phase I Final Report summarizes the analytical, experimental, design, and specification efforts for the first nine months of the Dallas/Fort Worth Airport Fresnel/Photovoltaic Concentrator Application Experiment. The overall objective of the complete three-phase program is to develop and demonstrate a unique photovoltaic concentrator total energy system which, when mass-produced, will provide electrical and thermal energy at costs competitive with conventional energy sources. Toward this objective, the Phase I - System Design contract has been completed, resulting in a final system design, analytical definition of system performance and economics, and a successfully tested prototype collector which fully verified performance predictions. The proposed system will utilize 245 m exp 2 of E-Systems linear Fresnel photovoltaic collectors to provide 25 kW/sub e/ (AC) of power and 140 kW/sub t/ of heat to the Central Utility Facility of Dallas/Fort Worth Airport. The electric power will be used to meet a continuous lighting load, while the thermal energy will be used to preheat boiler feedwater. Peak system efficiencies will be 10.2% electric (insolation to net AC output) and 56% thermal (insolation to net heat delivered). Annual efficiencies will be 8.4% electric and 49% thermal. Production system economics are attractive in the near term: 7 cents/kWh electricity and $7/MMBtu heat (1975 $) could be achieved by 1981 with limited production. With higher production, these costs could be halved by 1990. (ERA citation 05:015309)
