Solar preheated water is supplied to a commercial laundry plant by an active system consisting of 6528 square feet of single glazed flat-plate collectors, 12,500-gallon fiberglass storage tank, auxiliary steam boilers, and a 16,500-gallon water pump with tube-shell heat exchanger for feedwater preheat. The system is designed to provide 20% of the water heating load by solar energy. The solar fraction measured is 18%. Other measures of performance are given, including solar savings ratio, conventional fuel savings, system performance factor, and solar coefficient of performance. The collector, storage, laundry hot water, and heat recovery subsystem performances are also discussed. The laundry's operating energy and weather data are given. (LEW)
