Collector array performance report for sites of the National Solar Heating and Cooling Demonstration Program

OSTI ID:5606507

A major goal of the National Solar Heating and Cooling Demonstration Program is to collect and analyze data which will be used to determine the thermal performance of selected solar energy systems. To meet the goals and objectives of the Demonstration Program, the National Solar Data Network (NSDN) has been developed for the Department of Energy by the Federal Systems Division of the International Business Machines Corporation. The network consists of sensors which measure key performance parameters at a selected site, a Site Data Acquisition System (SDAS), telephone transmission circuits and a Central Data Processing System (CDPS) which collects data and performs the computations required for system performance analysis. The output of the National Solar Data Network is a monthly performance report which defines the energy contribution of the solar energy system and resultant fossil fuel savings. Data for all operational solar energy systems being monitored by the National Solar Data Network are given for the month of July 1979. The following data are given for each site: (1) single-panel instantaneous efficiency curve coefficients; (2) current month instantaneous efficiency curve coefficients; (3) cumulative (through current month) instantaneous efficiency curve coefficients; (4) cumulative (through current month) second order curve coefficients; (5) daily energy gain comparisons for the current month; (6) properties of the collector transport fluid; (7) array flow rate (average for the month); (8) single-panel flow rate; (9) array temperature gain (average for the month); and (10) monthly energy gain comparisons for the most recent 12 months.
