Cramer, M.

Craftsman Enterprises is an industrial laundry in Dallas, Texas. The active solar energy system is equipped with 1011 square feet of liquid collector panels, a 2000-gallon steel storage tank, and two 100-gallon gas-fired hot water heaters in series with a condensate heat exchanger which is piped to a steam boiler. The solar fraction, solar savings ratio, conventional fuel savings, operating energy expenditure, system performance factor, and solar system coefficient of performance are given for the year. Monthly performance data are given for the solar energy system overall, the collectors, storage, and the process hot water subsystem, and monthly weather data are tabulated. Typical system operation is presented in the form of typical storage and collector array temperatures graphed against time for a 24 hour period. The system operating sequence is also graphed and the use of solar energy and the percentage of losses are given. (LEW)
