Solar production of industrial process hot water. Quarterly performance report, January-March 1980

The performance of the Campbell Soup solar hot water facility is tabulated for January through March 1980, from each of the monthly performance reports. The data during this period indicates that the system is operating with good reliability (95 percent in February, 90 percent in March). Of the days that the system was not operating in those months, only one was for work on the system, one was for testing of the flat plate collectors, and the remainder were due to the system not operating because the storage tank was full. The data also show that the system was operating consistently at good thermal efficiency (50 percent). Actual measured system performance is compared with calculated values. The measured energy to storage values is lower than the predicted values primarily due to the collectors receiving less than the predicted insolation during operation. The system was controlled by a clock timer and ran only 6 hours a day, thereby missing available insolation. The system controls have been revised to permit collector operation whenever there is available insolation. On 6 days in March, the system shut down early because the tank filled up, thereby losing about 24 hours of system operation. It is …
